Zest, similar to Pendle, but separates yield from asset price volatility. Users can deposit Blast_ETH to borrow stablecoin zUSD (a yield-bearing stablecoin), earning leveraged Blast_ETH native yield. Another product is mirror ETH token (leveraged ETH derivative), offering users on-chain leveraged ETH derivatives. Pendle separates the yield and principal of yield-bearing assets, and Zest separates the yield and price volatility of yield-bearing assets.
