Fun Fact: @CurveFinance has built a network of PegKeeper pools around ethereum:0xf939e0a03fb07f59a73314e73794be0e57ac1b4e, using different stablecoins to help manage its peg. In 2025, Frax plugged ethereum:0xcacd6fd266af91b8aed52accc382b4e165586e29 directly into that system through the frxUSD/crvUSD PegKeeper. The PegKeeper was added to Curve’s monetary policy system, while the pool’s price oracle was integrated into the aggregated crvUSD oracle. ethereum:0xcacd6fd266af91b8aed52accc382b4e165586e29 is therefore part of the actual infrastructure supporting the crvUSD peg. Frax gets another use case for frxUSD liquidity. Curve gets another source of stablecoin liquidity that can help keep crvUSD around $1. Both protocols are effectively building on top of each other’s infrastructure. Proper DeFi OG engineering.
