UniswapV3ExecutionAdapter

Execution adapter for Uniswap V3 pools

amountOutMinimum is set to 0 at the Uniswap level because slippage protection is enforced by the LiquidityOrchestrator. This avoids duplicating slippage checks.

constructor

constructor(address initialOwner_, address factoryAddress, address swapRouterAddress, address quoterAddress, address configAddress) public

Constructor

Parameters

factoryAddress	address	Uniswap V3 Factory address
swapRouterAddress	address	Uniswap V3 SwapRouter address
quoterAddress	address	Uniswap V3 QuoterV2 address
configAddress	address	OrionConfig contract address

setAssetFee

function setAssetFee(address asset, uint24 fee) external

Sets the fee tier for a given asset

Parameters

Name	Type	Description
asset	address	The address of the asset
fee	uint24	The fee tier to set

validateExecutionAdapter

function validateExecutionAdapter(address asset) external view

Validates that the given asset is compatible with this adapter

Parameters

Name	Type	Description
asset	address	The address of the asset to validate

previewBuy

function previewBuy(address asset, uint256 amount) external returns (uint256 underlyingAmount)

Previews the underlying amount required to buy a given amount of an asset

Particularly useful in keeping execution adapters composable with each other, making refunding unnecessary when higher-level adapters use the previewed amount for downstream buy() calls.

amount	uint256

Return Values

Name	Type	Description
underlyingAmount	uint256	The underlying amount required

sell

function sell(address asset, uint256 amount) external returns (uint256 receivedAmount)

Executes a sell operation by converting asset shares to underlying assets

Parameters

Name	Type	Description
asset	address	The address of the asset to sell
amount	uint256

Return Values

Name	Type	Description
receivedAmount	uint256

buy

function buy(address asset, uint256 amount) external returns (uint256 spentAmount)

Executes a buy operation by converting underlying assets to asset shares

Parameters

Name	Type	Description
