Does your DAO want to delegate treasury management but keep custody? Or trustlessly automate your yield?

Check out our Smart Vaults to automate DeFi operations in a secure, trustless, and non-custodial way.

For DeFi projects: you can also automate collecting your fees across chains and swapping/distributing them.

Previously Mimic’s co-founders helped build POAP, Balancer, and OpenZeppelin, among others.  Backed by Starbloom Ventures.
