rDEX V2 is Deployed on the StaFiHub Testnet with The Bug Bounty Program


After several rounds of internal testing, rDEX V2 is now deployed on StaFiHub testnet to be open to our community to test. rDEX V1 officially went live on the substrate-based StaFi Chain three months ago after the completion of testnet Bug Bounty and PeckShield security audit. During the past three months, rDEX has proven to be safe to our community. Now we have upgraded rDEX V1 to V2 with new features and deployed the V2 on StaFiHub testnet.

With rDEX V2, StaFiHub users can trade the rTokens issued on StaFiHub against the base token, like rATOM against ATOM, and not the rATOM against FIS token on StaFi Chain. We think that this new feature will greatly improve the capital efficiency of liquidity providers and create a friendly arbitrage mechanism to help peg the rToken trading price with the real on-chain exchange rate. For now, rDEX V2 testnet supports 2 trading pairs: rATOM/ATOM and rIRIS/IRIS.

StaFi hereby announces with excitement that the rDEX V2 on StaFiHub testnet is live to the community from today: The StaFi team welcomes any users and developers participating in the testing of rDEX V2, and for that, we have prepared incentives as well as considerable bounty rewards for users and developers who find bugs and vulnerabilities.

rDEX V2 Key Features

rDEX is very important for StaFi protocol’s staking derivative eco as the decentralized trading platform for all the rTokens. rDEX V2 has the following new features:

  • Trading rTokens against base tokens: Compared with rDEX V1, rDEX V2 supports trading between rTokens issued on StaFiHub and the base token.
  • Continuous Liquidity: rDEX is an automated market maker DEX to provide continuous liquidity for rTokens by utilizing Thorchain’s CLP market maker model.
  • Lower Slippage: rDEX ensures low slippage for small and medium-sized transactions by using the fee model based on slippage.
  • Asymmetrical Deposit: Unlike the majority of cryptocurrency liquidity pools, rDEX users can provide liquidity by depositing one token or two tokens asymmetrically.
