Claiming Trading Fees
Every time a trade occurs on Curve Finance, 50% of the trading fee is collected by users who have vote-locked their CRV. Furthermore, since the introduction of Curve's stablecoin, crvUSD, all accumulated interest rate fees are awarded to veCRV holders.
Fees are collected weekly from the pools, converted to 3CRV, and then distributed. Users who lock CRV can claim trading fees as often as they wish; however, fees will only be converted into 3CRV once a week.
Info
There is a delay before the first claim of 3CRV can be made after locking. A wait of 8 days from the Thursday following the lock is required before a claim can be done.
To claim trading fees, visit https://curve.fi/#/ethereum/dashboard and click the Claim LP Rewards button.
when using the classic UI please visit: https://classic.curve.fi/ and look for the green Claim button in the box labeled veCRV 3pool LP claim at the bottom of the page.
Swapping 3CRV for a Stable Coin¶
3CRV is the liquidity provider (LP) token of the 3pool, which consists of USDC, USDT, and DAI. If the pool is perfectly balanced with 33% USDC, 33% USDT, and 33% DAI, then one 3CRV will represent 0.33 USDC, 0.33 USDT, and 0.33 DAI.
If a user wishes to withdraw 3CRV back into a stablecoin, they can do so at: https://curve.fi/#/ethereum/pools/3pool/withdraw. The user needs to select the stablecoin they would like to receive (withdrawing in a balanced or custom proportion is also an option) and click Withdraw. After the transaction is confirmed, they will receive the withdrawn stablecoin.
Note
When withdrawing 3CRV into a stablecoin, it might be beneficial to take a look at the balance ratios of the pool. Withdrawing in a token with a higher balance than the other two could result in a small premium for that token. On the other hand, withdrawing a token with a lower balance relative to the other two coins may lead to receiving a slightly lesser amount. Further information can be found here.
How does it all work?¶
When the burn process is initiated, a contract collects fees, which come in dozens of different forms such as stablecoins, volatile assets, or LP tokens. These tokens are then burned through various contracts and pools, and converted into 3CRV by adding liquidity to the 3pool.
Burning is a costly process due to the complexity and number of transactions involved. However, anyone can trigger this process at any time, provided they are willing to cover the associated costs.
Fees can only be claimed for the week that has already concluded, as the burner cannot determine each user's entitlement before the end of that period. Fees will be made available weekly, within 24 hours after Thursday midnight UTC, as long as someone — typically the Curve team — has initiated the burn process beforehand.
