What does it cost in ETH to claim pool fees on Optimism?
On Optimism, a fee claim carries a Tokenry fee of 0.0015 ETH plus gas, with both paid in ETH. If you locked a v4 position with Tokenry's pool creator, its claim costs gas and no Tokenry fee.
Does claiming fees on Optimism remove liquidity or close my position?
No. A fee claim on Optimism sends you the position's unclaimed fees and leaves the position open, so you claim trading fees without removing liquidity. Tokenry's contract rejects a claim that would take out liquidity or burn the position NFT. Removing liquidity from a v3 or v4 position also pays out its fees, so remove only when you want the liquidity out.
Can I claim the fees of Uniswap v2 LP tokens on Optimism?
No. On Optimism, Uniswap v2 puts trading fees straight into the pool's reserves, so they sit inside your LP tokens. They come out when you remove liquidity on Optimism. Uniswap's fee docs explain the difference: v3 and v4 fees are collected separately by the position owner.
Are Optimism LP fees paid in ETH, WETH or OP?
Your Optimism position pays its trading fees in the pool's 2 tokens, not in OP, unless OP is one of them. In a pool paired with ETH, the ETH side arrives as ETH: native from a v4 pool, unwrapped from WETH on a v3 pair. When a v3 ETH pair holds a token with a tax or limits, its ETH side comes as WETH, which the review shows. A USDC pool pays its USDC side as it is.
Can I claim fees from a locked position on Optimism?
Yes, you can claim fees from your locked Uniswap v4 position on Optimism if the lock was made with Tokenry's pool creator. That lock is the "Lock forever, keep the fees" option you pick as you create a liquidity pool on Optimism with Uniswap v4. The claim tool shows the position to the wallet set at launch, marked "locked" next to its range. Its claim is a single transaction, with no NFT message to sign.
Which Uniswap positions on Optimism can I claim fees from?
Tokenry's claim tool collects Uniswap v3 and v4 fees on Optimism from positions whose pool fee is 0.01%, 0.05%, 0.3% or 1%. Positions on another Optimism DEX, such as Velodrome, are claimed in that DEX's own app. The Uniswap app can also collect these v3 and v4 fees. If a position does not show up, paste its pool or token address.
What do I sign to claim fees on Optimism?
To claim fees on Optimism, you first sign a message that gives Tokenry's contract use of that one position NFT for this claim. Then you confirm the claim transaction. Inside that transaction, the contract pays the fees out to you and gives the NFT back. Only the position's owner can send the claim transaction, and no token approval is needed. Tokenry never holds your keys.
