Koi farm, LP and rewards still staked

Steps in “How to get it out” are written from how the farm contracts behave on-chain. They have not yet been walked through in the live app.

For the complete exit, including LP, fees, Amplifiers and farms, read the Mute.io and Koi withdrawal guide.

What it is

Koi, first called Mute, ran farms on zkSync Era: you staked the LP token of a pool and earned a reward (KOI, MUTE, ZK, or the token of a partner project) that vested over 30 days. Koi’s home page now points to Robinhood Chain, but the farms are still on zkSync Era. On 2026-11-01, 16 of them still held about $152,000 of LP, and their rewards were still being paid out.

The stake and unpaid reward are separate. Withdrawing early can forfeit unvested rewards, and payout also depends on the reward payer holding enough tokens.

Who is eligible

Any wallet with a stake in one of the 16 farms. The source of these contracts is not published, so the check reads them by their raw function code (0x64c73e00), checked against real claims. It adds up your stakes in each farm and shows your share of both tokens of the pool at today’s reserves, plus the reward not paid yet.

How to get it out

Before copying a recipient, use your own wallet, never transaction history, and compare the complete address to avoid address poisoning. Verify the full contract destination separately.

1. Check the date first. Rewards vest over the month after each deposit, and withdrawing before that forfeits the part not vested yet (Koi’s docs). The report gives the date when a reward is still vesting; most stakes vested long ago.
2. Open Koi’s app at https://dapp.koi.finance, connect your wallet on zkSync Era and look for your farm position. Withdrawing pays everything in one transaction: your LP token, the vested reward and the pool fees earned while staked.
3. If the app no longer lists the farm, a wallet that lets you send custom data can call it directly: send a transaction to the farm shown in the report, with no ETH and the data 0x3ccfd60b (the code of withdraw()). Block explorers show no write button, because the source is not published.
4. You now hold the pool’s LP token. Remove the liquidity to get both tokens back (see the Koi liquidity check for the steps).

Each reward is paid from a separate contract. The check reads that contract’s balance: when it holds less than your reward, the report says the reward cannot be paid today instead of counting it as yours. Other stakers claim from the same contract, so even a covered reward is not reserved for you.

What it costs

Three zkSync Era transactions: the withdrawal (up to 847,906 gas in real claims, most under 530,000), then the approval and the removal of the liquidity (up to 462,088 gas together). About 13 cents in total on 2026-11-01.

Deadline

No deadline. People were still withdrawing from these farms in October 2026.

How to check

Scan your address without connecting a wallet or signing. Review incomplete results and coverage limits before deciding whether to use the official app.

FAQ

Can an early withdrawal lose rewards?

Yes. Koi documents forfeiture of unmatured rewards on early withdrawal. Check the vesting date before acting.

Is the unpaid reward reserved for me?

No. A separate reward payer serves other claims too, so its current balance is not a reserved allocation.

What does withdrawing a farm cost?

Recorded farm withdrawals used up to 847,906 gas in the 2026-11-01 verification. LP approval and removal are separate steps budgeted at up to 462,088 gas together.
