IAdapter

Basic interface for Nexera-Fi Adapters.

Enums

Operation

Defines the various generic operations that Adapters can conduct:

DEPOSIT: For adding liquidity to DeFi Protocols
WITHDRAW: For removing liquidity from DeFi Protocols
SWAP: For performing token swaps against Pools
COLLECT: For collecting generated fees and rewards
OPERATE: For protocol-specific interactions

enum Operation {
    DEPOSIT,
    WITHDRAW,
    SWAP,
    COLLECT,
    OPERATE
}

Structs

TokenAmount

Defines data for an individual token composition.

struct TokenAmount {
    address token;
    uint256 amount;     
}

Members

Name	Type	Description
`token`	`address`	The address of the target token: - address(0) signifies blockchain native currency.- non-zero address signifies ERC-20 compatible token.
`amount`	`uint256`	The amount of the target token

Functions

executeAction

Executes an operation-related action on a 3rd party service (DEX, Liquidity Pool, etc).

function executeAction(
    IAdapter.Operation op,
    IAdapter.TokenAmount[] calldata out,
    IAdapter.TokenAmount[] calldata expectedIn,
    bytes calldata extraData
) external returns(IAdapter.TokenAmount[] memory actualIn);

Parameters

Name	Type	Description
`op`	`IAdapter.Operation`	Enum key representing the operation
`out`	`IAdapter.TokenAmount[]`	Array of `TokenAmount` structs defining the token compositions to send
`expectedIn`	`IAdapter.TokenAmount[]`	Array of `TokenAmount` structs defining the expected token compositions to receive
`extraData`	`bytes`	Extra ABI encoded data specific to the Adapter, required for the operation action

Returns

Name	Type	Description
`actualIn`	`IAdapter.TokenAmount[]`	Array of `TokenAmount` structs defining the token compositions actually received

initialize

Virtual intialization function for Adapters.

Developers should override this function to appropriately initialize their Adapter implementation.

function initialize(bytes calldata initData) external virtual;
