stYFI (Governance Staking)

Yearn’s current governance staking UX is built around stYFI (and stYFIx).

  • stYFI: stake YFI to earn rewards and keep direct governance rights.
  • stYFIx: a “set-and-forget” option that delegates voting power (recommended if you don’t want to manage governance actions yourself).

Where to use it​

Stake (YFI → stYFI / stYFIx)​

Staking is a two‑step flow:

  1. Approve YFI for the contract you’re using.
  2. Stake YFI to mint stYFI or stYFIx.

The interface uses exact‑amount approvals (not infinite approvals).

Unstake and withdraw (14‑day linear cooldown)​

Unstaking starts a 14‑day linear cooldown:

  • funds unlock gradually during the stream
  • you can withdraw the currently unlocked portion without waiting for the full 14 days

If you add more to an active cooldown:

  • any currently‑unlocked amount is auto‑withdrawn first (so it can’t be re‑locked), and
  • the cooldown timer resets for the remaining streaming amount

The UI will warn you before you confirm a reset.

Rewards (claim yvUSDC)​

Rewards are claimable from the stYFI dashboard and are paid in yvUSDC (a Yearn vault token).

Notes:

  • stYFIx does not auto‑compound in the current implementation.
  • Rewards accrue separately and still need to be claimed.

If you have legacy veYFI​

If you held a legacy veYFI lock, you may be able to migrate it to the current system and activate a boost used by the dashboards.
