rDEX V1 is LIVE on Testnet, Join rDEX Bug Bounty and Win FIS Reward


After thorough internal testing, rDEX V1 has been launched on the testnet. rDEX is an AMM DEX that solves liquidity problems for StaFi native rTokens (rETH, rBNB, rFIS, rDOT, rKSM, rATOM, rSOL, rMATIC). ​​Once accessible, native rTokens minted by users can directly be traded through rDEX for better liquidity. This will eliminate the need for cross-chain migration to Ethereum or other ecosystems.

rDEX has the following features:

1.Low slippage in small and medium-sized transactions, which is realized through the AMM CLP market maker model.

2.FIS as the basic trading asset for all rToken trading pairs to promote liquidity.

3.Impermanence loss protection, whereby the loss incurred by Liquidity Provider will be compensated by FIS token.

4.Liquidity can be provided by any single currency or a dual-currency model with different ratios.

StaFi is excited to announce that the rDEX is live on the testnet from today: The StaFi team welcomes any users and developers participating in the testing of rDEX. We have also prepared incentives as bounty rewards for any user or developer who finds out and reports bugs and vulnerabilities.

For a detailed introduction to the rDEX solution, please check:
