Curve

Curve pools in Yield show wallet LP holdings and supported Staked direct Curve gauges. On Ethereum, a pool with staking uses its supported gauge for new Sickle deposits. Other supported NG chains retain their LP-only option alongside compatible gauge options. Wallet LP tokens and existing recovery holdings keep their own actions. A Stake DAO vault is a separate choice when available. Existing positions appear under their actual holding contract.

Standalone support covers the direct coins handled by deployed Curve connectors, with two through eight ordered inputs for plain StableSwap-NG pools on supported chains. Fixed and crypto pools retain their connector limits. Available gauges use Ethereum Minter, sidechain child-factory, or reward-only connectors.

Deposit and increase

Select existing LP tokens to deposit them without changing underlying liquidity. Select the combined pool-token option to supply every direct coin in pool order, with one total split across the coins. Manual token amounts remain in place when the same token’s metadata or balance refreshes; choosing another token resets its amount. The fiat amount updates when the token price or display-currency rate changes. The pool-token row accepts one total, and You provide lists each coin with its balance, its amount and a bar for the share of that balance in use. Type the total or one coin’s amount, in the coin or your display currency, or drag a coin’s bar; the Auto split badge marks that the other coins follow the pool’s reserve ratios. The total starts at the maximum your balances cover; enter a smaller amount or drag a bar to deposit less, and MAX returns to the maximum. Native ETH can replace WETH in a pool-token combination; network gas is reserved before calculating its maximum.

Single-token deposits and withdrawals use available swap routes and prices. Metapools accept their direct coins, including a base-pool LP token. Expanded underlying deposits, one-coin exits and imbalanced exits are unavailable. Liquidity quotes protect LP mint amounts and each nonzero proportional output with positive minimum amounts.

Some pools restrict adding or removing underlying liquidity. Their action pane explains the restriction, and compatible held LP returns remain available. The reviewed yETH pool currently offers held LP recovery only. Disabling deposits does not hide an existing wallet or Sickle holding.

Direct gauge rewards

Ethereum gauges can pay Minter CRV, extra reward tokens, or both. Sidechain child gauges claim CRV through their authenticated child factory; reward-only gauges claim their extra streams. Harvest claims them, and Compound reinvests through available routes. Rewards accrued in an expired extra stream remain claimable after its displayed emission rate becomes zero. A zero gauge weight alone does not disable staking.

For Ethereum and child gauges, pending CRV is a lower bound: it may understate the amount eventually claimed. The position’s Rewards tooltip explains this estimate; extra rewards use their reported claim amounts. Reward-only gauges do not accrue minter CRV. Reward automation uses the conservative CRV estimate. Browse APR uses an unboosted estimate; a held position uses the working balance reported by the API. These calculations are separate from Stake DAO vault rewards and boost calculations.

When a legacy gauge’s extra reward rate is unavailable, its APR stays unavailable in Yield and Positions. Known token balances and claim amounts remain visible.

Incomplete or stale reward reads pause Sickle action quotes while retaining the holding and its recovery information. After complete reads return, quotes resume. A killed gauge disables new staking, Increase and compounding into it; compatible claims and LP returns remain available. Wallet claims include CRV accrued before the kill. Wallet actions support the API’s stable, crypto, lending and NG pool families; the gauge’s authenticated reward ABI determines which claim calls are needed. Extra emissions can continue on a killed gauge.

Swap-fee and volume history are unavailable for broader crypto and multi-coin pools. The UI keeps those values unavailable and identifies gauge reward APR separately. When a funded coin has no available price, pool and farm details show TVL and that token’s price as Unavailable, while reserves and rewards retain their token quantities. The yield table shows a dash for Curve liquidity values when any underlying coin lacks a finite, positive price. Existing Curve fee estimates and off-chain campaigns continue to use their own data.

Wallet receipts and recovery

Wallet LP holdings and direct gauge stakes appear in the Wallet positions dialog under Positions, including receipts received by transfer. Open it from the Wallet positions chip in the filter bar, then choose Recover to open their actions.

For direct gauges, Return LP to wallet withdraws the chosen receipt amount to LP tokens. Claim gauge rewards claims minter CRV and all extra slots when reward reads are complete. Transfer to Sickle transfers the selected LP tokens or gauge receipts to your own Sickle, deploying it first when needed. The transfer preserves the actual holding contract and does not select another farm. Accrued gauge rewards stay claimable by the sending wallet.

A wallet-held gauge stake can return its LP tokens without removing underlying liquidity, including for killed or replaced gauges. vfat checks the gauge’s live LP binding before preparing the return.

Ethereum gauge profiles distinguish plain CRV-only, single-reward, fixed V2/V3 and modern reward ABIs. A plain gauge only needs its minter claim. Other gauges claim supported extras; a single-reward gauge with no unclaimed extras does not add an empty extra claim. Ethereum reward-only gauges skip the CRV minter. Sidechain child gauges use their own verified factory, and reward-only sidechain gauges claim extras alone.

Only transferable gauge receipts offer Transfer to Sickle. For a legacy stake without transferable receipts, use Return LP to wallet, then transfer those LP tokens for compatible Sickle actions. If transfer support cannot be read, LP return remains available. Changing a wallet stops the original action; refreshing the same position’s balance preserves a manually entered recovery amount.

After transfer, open the Sickle position in Positions. An existing LP recovery position offers Return full LP balance, which returns its full current amount. For a partial withdrawal, choose the combined pool-token option to receive proportional underlying coins when liquidity removal is supported. Direct gauge withdrawals can return part of the staked LP amount. LP return remains independent of restrictions on underlying liquidity. Direct external-wallet liquidity removal uses the explicit Sickle transfer path.

Sickle gauges use the existing Auto-harvest, Auto-compound and Auto-exit settings for implemented actions. Available actions still depend on current pool, gauge, reward and routing checks. When compounding is unavailable, the Compound tab keeps auto-compound settings available so you can disable saved automation. New activation and destination changes still require compatible holdings.
