Arrakis Finance (arrakis)

​

What it offers

• addLiquidity: Add liquidity to an Arrakis vault via router (tuple params)
• removeLiquidity: Remove liquidity from vault via router (tuple params)

​

Notes

• Manages UniV3 concentrated liquidity positions automatically
• Both addLiquidity and removeLiquidity take struct/tuple params via the router
• Approve both token0 and token1 to the router before adding liquidity
• Vault shares represent proportional ownership of the managed position
• gauge param can be zero address if not staking in a gauge
• The vault itself does not report its underlying amounts; ArrakisV2Helper’s totalUnderlying(vault) does

ArrakisRouterABI

• addLiquidity((uint256 amount0Max, uint256 amount1Max, uint256 amount0Min, uint256 amount1Min, uint256 amountSharesMin, address vault, address receiver, address gauge) params) payable returns (uint256 amount0, uint256 amount1, uint256 sharesReceived)
• removeLiquidity((uint256 burnAmount, uint256 amount0Min, uint256 amount1Min, address vault, address receiver, address gauge, bool receiveETH) params) returns (uint256 amount0, uint256 amount1)

​

ArrakisVaultABI

• totalSupply() view returns (uint256)
• balanceOf(address account) view returns (uint256)
• token0() view returns (address)
• token1() view returns (address)
