Lucky dApp — Sunset Announcement

Astar
1

Hello,

With the upcoming decommissioning of WASM smart contracts on Astar Network and Shiden Network, I regret to announce that the Lucky dApp will also be sunset.

After considering the different options, I have decided not to migrate Lucky to Astar EVM for several reasons:

  1. The future of Lucky within the dApp Staking ecosystem

    The ACC has already raised some concerns regarding Lucky’s continued presence in the program. Even if I migrated the dApp to Astar EVM, there would still be a strong possibility that Lucky would eventually be delisted from dApp Staking.

  2. The amount of work required for the migration

    Migrating Lucky would require rewriting and thoroughly battle-testing the three smart contracts, adapting the worker currently deployed on Phala Cloud, updating the SubQuery indexer, and making the necessary changes to the UI.

    This is a significant amount of work, and at this stage, I have decided that I would rather dedicate this time to my family than spend it rebuilding the project.

  3. Infrastructure and maintenance costs

    Even though we have tried to automate as much of the process as possible and build the most decentralized architecture we could, Lucky still requires infrastructure to operate, including Phala Cloud, a server for the UI, and SubQuery.

For all of these reasons, Lucky will be sunset when the WASM smart contracts are decommissioned on Astar Network.

What does this mean for users?

From a user perspective, the recommended action is simply to choose another dApp directly from the dApp Staking section of Astar Portal.

There are currently no user funds held by Lucky’s smart contracts, so there is no risk of users losing their tokens as a result of the shutdown.

Looking back

Lucky started as an opportunity for me to learn about smart contracts, ink!, Rust, and eventually discover the wider Web3 ecosystem.

It has been a really valuable experience, and I am grateful for everything I have learned along the way.

This is not really an end, but rather the natural next step of the journey. The experience gained from building Lucky will certainly be useful for whatever comes next.

Thank you to everyone who used Lucky, supported the project, provided feedback, or simply followed its journey.

It has been a pleasure building on Astar.

WASM smart-contract sunset on Astar and Shiden

Unfortunately, I suppose this is unavoidable.

WASM smart contracts were once a promising area, but unfortunately, their adoption has been extremely limited compared to EVM. And now that Polkadot itself has abandoned WASM smart contracts, maintaining that technology stack on Astar would involve significant costs and risks.

As we saw with the recent major incident involving Cosmos EVM, we cannot continue using a system when upstream maintenance has stalled.

It is unfortunate, but given the current situation, I believe this proposal is reasonable.

Thank you for all your hard work.

Hi @GuiGou,

Although I understand the decision, it is always difficult to see projects that have shaped our ecosystem leave. Lucky and Lotto were among the very few ink! dApps that actually shipped and ran in production on Astar, contracts, worker, indexer and UI, built and maintained by one person. They were also genuinely fun, which is rarer than it should be. It was great working and collaborating with you on both.

You put it well, this is a step in the journey rather than an end. Thanks again for everything you built here, and I hope you find new opportunities to put those skills to work in this industry and in our ecosystem.
