SwaptoX Aggregator – Relocation & Ecosystem Integration Proposal (Astar Network)

Governance dApp Staking Applications
1

Project Name: SwaptoX Aggregator
Category: DeFi Infrastructure / Swap Aggregator
Developer: Independent (Solo Builder)
Current Deployment: Base Network

Project Overview

SwaptoX is a swap aggregator designed to help users find better swap routes across multiple liquidity sources.
The project has been live on Base for over three months and currently supports more than 600 tokens.

Although SwaptoX is still in an early adoption stage, the swap execution logic has already been thoroughly tested.
Over the past six months, I have executed and verified tens of thousands of swap simulations and real transactions to ensure routing accuracy, execution safety, and contract stability.

SwaptoX is entirely self-developed by me as a solo developer.
From protocol logic, routing engine, UI, to pricing infrastructure, all components were built from scratch over more than one year of continuous development.

DApp: https://app.swaptox.com

Twitter: https://x.com/swapto_x

Additional Infrastructure Built

In addition to the swap aggregator itself, I independently built a token-to-USD pricing system that maps on-chain token prices to USD values.

This pricing system can later be exposed as an API, allowing:

Ecosystem projects to easily query token USD prices

Derivatives, trading bots, and analytics tools to integrate pricing data

Development & experience sharing:

Why Astar Network

Currently, Astar ecosystem lacks a mature, general-purpose swap aggregator infrastructure that ecosystem projects can easily integrate.

If supported, I plan to relocate SwaptoX to Astar and make it a native DeFi infrastructure component, providing:

Reliable swap routing

SDKs for ecosystem projects

APIs for advanced trading and derivatives

This would significantly lower the barrier for Astar ecosystem projects to add swap functionality.

Requested Relocation & Builder Support

I am applying for a small relocation and builder support grant to continue development and integration on Astar.

The requested support will be delivered through the following milestones:

Milestone 1: SwaptoX Migration to Astar

Deploy SwaptoX on Astar network

Integrate Astar-native tokens and liquidity pools

Ensure stable routing and execution

Timeline: 1 month

Requested support: $8,000

Milestone 2: Swap Mini SDK for Web Integration

Develop a lightweight Swap SDK for websites and DApps

Enable easy swap integration for Astar ecosystem projects

Timeline: 1 month

Requested support: $7,000

Milestone 3: Public API & Documentation

Develop a public Swap API

Provide full technical documentation

Enable usage by trading bots, derivatives, and advanced applications

Timeline: 1 month

Requested support: $5,000

Long-Term Value to Astar

SwaptoX is a foundational infrastructure project.
Once the above milestones are completed, SwaptoX will become a complete and extensible product with multiple future expansion paths, including:

Advanced routing strategies

Professional trading tools

Derivatives and automation integrations

This will provide long-term value to the Astar ecosystem with minimal upfront cost.

Closing

I am an independent developer who has already invested significant time and effort into building SwaptoX.
With Astar’s support, I can focus on delivering a production-quality swap infrastructure tailored for the Astar ecosystem.

Thank you for your time and consideration.

Hi @SwaptoX ,

Thank you for the detailed proposal. It is great to see builders from other ecosystems looking to expand and contribute to Astar Network.

I have reviewed your plan and have a few specific questions regarding the project’s long-term sustainability and technical implementation:

  1. Project Continuity & Solo Builder Since you are operating as a solo developer, this inherently poses a Solo Builder risk to the protocol. If you are unable to continue development for personal reasons, what is the contingency plan? Will the source code be fully open-sourced to allow the community or other developers to maintain the project if necessary?

  2. Security & Audits Security is paramount for DeFi infrastructure. With the requested budget, is there any allocation for a smart contract audit? As a solo builder, how can the community be assured of the Router contract’s security and safety before interacting with it?

  3. Liquidity Integration which specific Astar DEXs do you plan to integrate initially (e.g., ArthSwap,…)? Additionally, does your routing algorithm take gas fees into account alongside price impact to ensure the user truly gets the best net output?

  4. Could the team share the target metrics after 3 months (e.g., number of swaps, total volume, number of dApps integrating the SDK) for the Astar Council to easily monitor effectiveness?

Looking forward to your response.

Hi @ms-py , thank you very much for the detailed review and thoughtful questions. I’m happy to clarify the points below.

  1. Project Continuity & Solo Builder Risk

You’re right. SwaptoX is currently maintained independently by a single developer, which naturally carries the risks associated with independent developers. However, it also brings operational advantages, such as lower long-term maintenance costs.

To mitigate continuity risk without compromising core intellectual property, the following measures will be taken:

All external interfaces (Router ABI, SDK, and API layers) will be public and well-documented, allowing dApps to integrate safely and transparently.

Non-core components, including SDKs, API services, and example integrations, will be fully open-sourced.

The smart contracts will follow non-custodial, minimal-state designs, reducing operational and upgrade risk.

In the event that I am unable to continue development for personal reasons, I am open to:

Releasing additional documentation or partial source access under community or foundation coordination

Or transferring maintenance rights to an ecosystem-aligned party approved by Astar

The objective is to ensure ecosystem safety and continuity, while still preserving the core routing logic as proprietary technology, which is standard practice for swap aggregators.

  1. Security & Audits

Security is a top priority, especially for a swap aggregator that routes user funds.

Regarding audits:

With the current requested budget, a full professional audit is not fully covered, but the budget allows for:

Extensive internal testing

Public testnet deployment on Astar

Open-source release for community review

The Router design follows battle-tested patterns used by existing aggregators:

No custody of user funds

No upgradeable proxy

No external state dependency beyond AMM pools

The Router performs direct pool-to-pool swaps, minimizing attack surfaces compared to complex vault-based designs.

I am also open to:

A phased audit approach (e.g., partial audit or audit bounty)

Or collaborating with Astar-recommended security partners if available through the ecosystem

  1. Liquidity Integration & Routing Logic

For the initial Astar deployment, the planned DEX integrations include:

ArthSwap

Other Astar-native or officially supported AMMs, depending on liquidity availability at launch

Routing logic details:

The routing algorithm considers:

Pool price impact

Swap fees

Gas cost estimation

Routes are ranked by net output, not just raw price.

Multi-hop routing (1–3 hops) is supported, and the system avoids routes where gas costs outweigh price improvement.

This ensures users receive the true best execution, especially important on chains with smaller or fragmented liquidity.

  1. Target Metrics (3-Month Post-Deployment)

To allow the Astar Council to clearly evaluate effectiveness, the following 3-month targets are proposed:

On-chain swaps: 500–1,000 swaps routed through SwaptoX on Astar

Total swap volume: $300k – $500k (depending on ecosystem liquidity growth)

SDK integrations: 2–5 Astar-based dApps integrating the Swap Mini SDK

API usage: At least 1 external project (e.g., bot, analytics, or derivative tool) using the API

These metrics are realistic for an early-stage ecosystem while still being meaningful indicators of traction and utility.

Closing

SwaptoX is positioned as long-term DeFi infrastructure, not a short-lived application. The requested grant supports migration, tooling, and ecosystem enablement, with the goal of making SwaptoX a reusable and extensible component within Astar’s DeFi stack.

Thank you again for the opportunity and for the constructive feedback. I’m happy to adjust scope or milestones based on the Council’s guidance.

From a completely different perspective, there’s also the fundamental issue that there are currently no DEXs with meaningful liquidity on Astar besides ArthSwap.
A key assumption behind a DEX aggregator is that liquidity exists across multiple DEXs — what are your thoughts on this point?

This has a significant impact on both your revenue potential and, more importantly, on users’ motivation to use an aggregator in the first place.

Additionally, when considering the size of the requested grant, the actual impact it can deliver appears quite limited.
This is more of an ecosystem-level issue rather than your fault, but if grants are to be allocated, cost performance also needs to be taken into account.

Thank you for raising this point — I fully agree that this is a very important and realistic consideration.

You are absolutely right that, at the moment, meaningful liquidity on Astar is primarily concentrated on ArthSwap, and that a classic DEX aggregator is most effective when liquidity is distributed across multiple DEXs. In its current state, Astar does not yet resemble that environment.

However, this is also precisely where I believe the role of an aggregator on Astar today is different from mature ecosystems.

At this stage, SwaptoX is not positioned as a volume-driven or revenue-focused product. Over the next year, I do not plan to enable protocol fees, and I am even open to subsidizing swaps to encourage early usage. The goal is not short-term monetization, but product completeness and ecosystem readiness.

From an ecosystem perspective:

Besides ArthSwap, there are already several Astar DEXs with deployed contracts but limited liquidity. SwaptoX is designed to integrate these DEXs quickly once liquidity emerges, reducing future fragmentation and integration costs.

Currently, Astar does not appear to have a native swap aggregator, which gives SwaptoX a natural first-mover advantage as basic infrastructure.

For users and developers, even a single-DEX aggregator still provides value through standardized routing, a unified SDK, and future-proof integration, especially for dApps, bots, and derivative products.

Regarding grant size and cost efficiency, I understand the concern. My intention with this proposal is not to extract value from the ecosystem, but to build a foundational piece of infrastructure at an early stage, when the cost of doing so is lowest. Once liquidity and DEX diversity increase, the marginal value of having an aggregator already in place becomes significantly higher.

In short, SwaptoX on Astar is less about solving today’s liquidity problem, and more about lowering the barrier for Astar’s next phase of DeFi growth.

I appreciate the candid feedback and am happy to further adjust the scope or milestones to better align with Astar’s current ecosystem priorities.

I think the positioning makes sense given Astar’s current stage: treating the aggregator as foundational infrastructure rather than a revenue engine aligns better with today’s liquidity reality. If scoped correctly, the real value is not immediate volume, but reducing future friction once liquidity and DEX diversity increase.

That said, for grant evaluation, it may be useful to explicitly frame success metrics around readiness and integration (number of DEX adapters, SDK adoption, dev usage) rather than swap volume or fees. This would better reflect the long-term intent and help align expectations between the builder and the ecosystem.

gm gm, thanks Matt — I fully agree.

At Astar’s current stage, SwaptoX should be evaluated as foundational infrastructure, not a volume or fee-driven product. Framing success around readiness and integration makes much more sense given today’s liquidity reality.

I’m happy to align metrics accordingly, for example:
Number of Astar DEX adapters integrated
SDK release and early developer adoption
API / routing usage by dApps or internal tooling

These KPIs better reflect the long-term goal of reducing future friction so the ecosystem is ready as liquidity and DEX diversity grow.
I’m very open to refining milestones to match the Council’s evaluation framework.

Thanks again for the constructive guidance.

Over the past few days, I’ve been actively reading discussions in the Astar community, and I genuinely appreciate the openness and depth of technical dialogue here.

I particularly resonated with the points raised in “Astar: From dApp Staking to Astar’s Financial Hub”, especially regarding the critical role of liquidity in enabling a sustainable DeFi ecosystem. I shared my thoughts in that thread because I strongly agree that liquidity is a prerequisite, not an afterthought.

From this perspective, SwaptoX is designed to be liquidity-ready infrastructure rather than a short-term volume or fee-driven product.

Once meaningful liquidity emerges on Astar, SwaptoX can integrate new DEXs and pools rapidly. I am also willing to make a public commitment that SwaptoX will not charge any fees (Swap, SDK, or API) for at least one year after deployment on Astar.

For end users, SwaptoX can serve as a more efficient and reliable token swap entry point.

For developers, this solves a very practical problem:
when a dApp’s core token is USDC (or another stable asset), but users only hold $ASTR, projects are often forced to redirect users to external platforms just to perform a simple swap.

With SwaptoX, a developer can either:

integrate swaps natively within their product via the SwaptoX Mini SDK in a very short time, or

leverage the SwaptoX API for trading bots, pricing services, or derivatives.

This gives developers a full year of optionality — time to decide whether to continue using SwaptoX or to build their own in-house solution, without immediate pressure or lock-in.

For these reasons, I believe this is an appropriate moment for SwaptoX to join the Astar ecosystem — contributing to its infrastructure readiness while allowing the product itself to grow alongside Astar’s liquidity and DeFi expansion.

After further ecosystem review and technical validation, I’d like to propose a small adjustment to Milestone 1 to better align SwaptoX with Astar’s broader ecosystem direction — without requesting any additional funding.

Recently, I became more aware that Soneium is an EVM-compatible network closely connected to the Astar ecosystem, and that it already has active liquidity and on-chain usage. From a technical standpoint, supporting Soneium alongside Astar is a low-friction extension and significantly improves the practical usefulness of the aggregator from day one.

Rather than introducing a separate funded milestone, I propose to extend Milestone 1 slightly and include Soneium compatibility at zero additional cost.

Revised Milestone 1: SwaptoX Migration to Astar (+ Soneium Compatibility)
Deploy SwaptoX on Astar Network
Integrate Astar-native tokens and liquidity pools
Ensure stable routing and execution on Astar
Add Soneium network compatibility, including:
Network support
Token & pool integration
Routing validation
Ensure the routing architecture cleanly supports both networks
Timeline: ~45 days
Requested support: $8,000 (unchanged)

This adjustment improves the immediate real-world usability of SwaptoX while staying fully aligned with Astar’s ecosystem strategy, and does not increase the grant size or risk profile.

Milestone 2: Swap Mini SDK for Web Integration (unchanged)
Develop a lightweight Swap SDK for websites and dApps
Enable easy swap integration for Astar ecosystem projects
Timeline: 1 month
Requested support: $7,000

Milestone 3: Public API & Documentation (unchanged)
Develop a public Swap API
Provide full technical documentation
Enable usage by trading bots, derivatives, and advanced applications
Timeline: 1 month
Requested support: $5,000

I believe this small adjustment increases cost-performance, improves early liquidity coverage, and strengthens the case for SwaptoX as foundational infrastructure for the Astar ecosystem and its EVM-aligned networks.

I’m very open to feedback if the Council prefers a different structuring.

Hi @juminstock, @you425, @matt,

I wanted to clarify a process-related question and also explain a small forum issue on my side.

I originally intended to update the proposal title and milestones, but unintentionally created a new topic instead. That topic has since been closed; however, it seems the original thread may no longer be categorized under the “Proposal” section.

As the proposal has been live for about a week, I want to make sure I’m following the correct next steps. I’ve seen mentions on the forum of an approximate 7-day discussion period, but I’m not entirely clear on what conditions or actions are required for a proposal to move toward the voting stage, or whether any adjustments to the format or content are expected from my side.

If there’s anything I should do next — or if it’s simply a matter of waiting — I would really appreciate some guidance.

Thank you very much for your time.

Hello @SwaptoX!

Yes, you can change the categorization of your post without any problem. This is an action you can perform at any time by going to the original post and editing it. If you created a new post, it may have been an action on your part rather than something caused by the platform itself.

Regarding your proposal, if you wish to move forward, you will need to create the request through our Astar Governance.

Importantly, it must be submitted as a public referendum, since you require funds for infrastructure. Optionally, you may request a review by the main council.

15

Reply to @Juminstock and @Gaius_sama :

Thank you for the clear guidance on the governance process. I appreciate the opportunity to ensure this proposal aligns well with Astar’s ecosystem standards and expectations.

I would like to formally request a review by the Main Council for the SwaptoX relocation and builder support proposal, prior to proceeding to a public referendum.

To better support the Council’s evaluation, I have refined the proposal’s focus to emphasize its role as foundational infrastructure for both the Astar and Soneium ecosystems:

Soneium & Astar Readiness (OP Stack Synergy):
SwaptoX is already live and stable on Base, which shares the same OP Stack architecture as Soneium. This allows for a low-risk and efficient deployment path. We are prepared to support native liquidity routing and core swap infrastructure from the early stages of the Soneium mainnet.

Developer-First SDK (React, Vue, & Vanilla JS):
A key deliverable of this proposal is the Swap Mini SDK, designed to minimize integration friction for ecosystem builders. It will provide native support for React and Vue, while remaining fully compatible with Vanilla JavaScript, enabling adoption across DeFi, gaming, NFT platforms, and analytics dashboards.

Long-Term Alignment with Astar (Build2Earn):
This proposal is not positioned as a one-time grant. Our intention is to participate in the dApp Staking v3 program post-launch, ensuring that SwaptoX’s sustainability and incentives remain directly aligned with the long-term growth of the Astar and Soneium ecosystems.

I am happy to provide a technical walkthrough, discuss implementation details, or supply any additional information that may assist the Council during the review process.

I look forward to your guidance on the next steps.

16

@SwaptoX If you wish to request a review by the Main Council, you will need to tag the team charge (@Gaius_sama)

17

Thanks for laying this out clearly. I think requesting a Main Council review first is the right step, especially given this is positioning SwaptoX as foundational infrastructure, not just another app deployment.

The emphasis on OP Stack compatibility with Soneium, combined with a developer-first SDK, is particularly relevant if the goal is to reduce friction for builders and accelerate composability across Astar + Soneium from day one. Framing this as long-term alignment via dApp Staking v3 rather than a one-off grant also strengthens the proposal.

A technical walkthrough for the Council would likely help validate execution risk and clarify how this integrates with the broader DeFi direction currently being discussed.

18

Thank you for the thoughtful feedback — much appreciated.

Based on this guidance, I would like to formally request a Main Council review for the SwaptoX proposal before moving to a public referendum.

As suggested, I’m happy to provide a concise technical walkthrough to help validate execution risk and clarify how SwaptoX aligns with Astar + Soneium’s broader DeFi and infrastructure direction.

Tagging @Gaius_sama to kindly request the Council’s review and next-step guidance. Thank you.

19

Thank you for your interest in Astar.
Frankly, I admire you; doing all this on the Base network by yourself is commendable, but even in the age of AI, a team is needed for a more sustainable and optimized project.

I also believe it is necessary to work with an audit firm for security measures.

I am an active DeFi user, and I would be happy to see another aggregator join the Astar ecosystem. However, instead of a direct grant, the following process could be implemented: operating on Astar for a period of time → dapp staking application → UCG application → close communication with the foundation based on ROI and potential investments.

Reply to @mrkarahanli-emre :

Thank you very much for the thoughtful reply and the encouragement — I truly appreciate it.

Regarding the solo builder point: while I am currently developing SwaptoX alone, this also means very low burn and high execution efficiency. My plan is to continue as a solo builder in the near term and gradually form a small team in the second half of 2026, once the product and ecosystem traction are more solid.

On security and audits: I fully agree audits are important. That said, SwaptoX does not custody user funds, and all swaps enforce strict minimum output checks with full transaction reverts on failure. This significantly reduces risk at the current stage. Given my limited resources, a formal audit is not my top priority right now, but it is absolutely part of the longer-term roadmap once funding allows.

As for the suggested path (operate → dApp staking → UCG): I understand and respect this approach. However, I want to be transparent that I have been building full-time for over a year on Base without any grants, sponsorships, or meaningful revenue. At this point, some level of direct financial support is critical for me to continue building sustainably and to eventually reach the stage where dApp staking and ROI-based evaluation make sense.

My intention with this proposal is not short-term gain, but to secure enough runway to keep contributing long-term to Astar’s DeFi infrastructure.

Thank you again for taking the time to share your perspective.
