Compound

Supply the base asset to a Compound V3 market and hold the cToken that represents your position.

Compound V3 (Comet) runs one money market per base asset per network. You supply that network’s base asset to the market and earn a variable supply rate paid by borrowers, plus COMP incentives where Compound is running a rewards campaign on that market. yield.xyz exposes one lending yield per market.

Entering

Enter takes a required amount. yield.xyz builds an approval transaction (skipped if allowance already covers the amount) followed by the supply transaction. Compound issues the cToken in the same transaction.

Exiting

Exit takes an amount and an optional useMaxAmount flag to redeem the full cToken balance. Compound burns the cToken and returns the base asset in the same transaction. There is no cooldown or unbonding step.

Rewards and position

The cToken balance grows over time as interest accrues; pricePerShare on the balance is 1. The yield’s public rewardRate combines the market’s on-chain supply rate with Compound’s published COMP rewards rate for that market into a single figure, where a rewards campaign is active.

COMP is claimed manually. When the market is running a rewards campaign, the balance response for the position carries a claimable balance with a CLAIM_REWARDS pending action; COMP is not paid out automatically when you exit the position, so claim it separately with a manage action before or after exiting.
