Yearn Finance has eliminated all protocol fees from their v3 vaults, offering builders:

  • Battle-tested, audited vault infrastructure
  • Complete fee control for vault deployers
  • No need to fork vaults to remove built-in fees

The change follows a successful governance proposal and simplifies vault deployment through their factory system.​ Builders can now launch custom vaults directly from Yearn's documentation.​
