Perena, founded by Anna Yuan, the former head of stablecoins at the Solana Foundation, completed a pre-Seed round of about $3 million, led by Borderless Capital. According to Anna Yuan, Perena is building exchange pools that allow traders of up to seven different stablecoins to easily swap assets between them - just as Curve's 3pool has done on Ethereum. Stablecoin holders will be able to earn additional gains by borrowing their assets into the pool, with more based on their risk tolerance.
