JPYC (JPYCoin) is the first Japanese Yen Stablecoin in Japan utilizing blockchain technology (ERC20). It runs on the Ethereum mainnet, Polygon, Xdai and can be used to buy and sell goods at 1 JPYC = 1 yen at all times. It can be used as a Japanese Yen denominated coin in your wallet, such as Metamask, or in the secondary distribution market, such as Uniswap.

It’s the only stable coin in japan, which is working in accordance with Payment Act Law in Japan.

Future plan

We are thinking of expanding both Defi area and Payment area as JPYC is a stable coin that is working in accordance with payment act law in japan

(Defi area)

  • Expand JPYC on Multi Chain (Ex.Astar, Avalanche, Solana, etc)

  • Start liquidity mining program on DEX on Astar network.

  • List JPYC on Major Exchanges.

  • Make a partnership with other stable coin company (ex Circle)

(Payment area)

  • Expand JPY Payment with an external merchant, making our payment API available to every merchant in Japan.

  • Enable JPYC minted from Astar to exchange e-money. (ex. V-Preca gift, which is online money that can use be used at online Visa merchant.)


Cant say more, we definitely need


Great to have JPYC on Shiden!

It seems JPYC needs liquidity for the stability of the value.

Usually, we support projects through dApp Staking(for Application track) or Grant(for infra track & proven dApps), but supporting JPYC through providing liquidity seems a good option. Ecosystem Growth Fund is able to help this.


suggest support lquidity more well


Thank you very much for your comments.

Yes, as you mentioned, we are working on having more liquidity of JPYC, and we hope we work with Shiden for not only liquidity, but also creating new network synergy for each other. for both Defi and Payment area.

At this moment JPYC is quite popular in some Japanese Market in some defi services such as SushiSwap(Kashi), QuiickSwap and so on.

It will for sure bring community the opportunity of Japanese yen Stablecon.
