R2, a yield-bearing stablecoin protocol, has officially launched its final testnet and plans to go live with its mainnet in September. Within just a few weeks, the protocol has attracted over 385,000 user addresses, with more than 50,000 daily active addresses, and has been integrated across more than seven blockchain networks. Its native cross-chain bridge is set to launch on July 11, further expanding access to composable on-chain yield strategies.
