LiquidityGauge

When an LP token is whitelisted on LendingLedger, a LiquidityGauge wrapper is automatically created. This simple wrapper calls sync_ledger in the _afterTokenTransfer hook to ensure eligible LP positions are continuously tracked by the protocol.

Depositing

To deposit LP tokens into a wrapper, call the depositUnderlying(uint256 _amount) method. The wrapper must be approved to spend the underlying token.

ethers.js

await LiquidityGauge.depositUnderlying(10000000000000000000) // Deposit 10 LP tokens

foundry

cast send --ledger 0x... "depositUnderlying(uint256)" 10000000000000000000

Withdrawing

To withdraw LP tokens from a wrapper, call the withdrawUnderlying(uint256 _amount) method.

ethers.js

await LiquidityGauge.withdrawUnderlying(10000000000000000000) // Withdraw 10 LP tokens

foundry

cast send --ledger 0x... "withdrawUnderlying(uint256)" 10000000000000000000
