Importing ABI

ABIs

ABIs (Application Binary Interface) define the contract interface, including function signatures, parameter types, return types, and event definitions. For detailed information, refer to the Understanding ABIs section.

Built-in ABIs

The library includes pre-built ABIs for standard contract types. The table below lists the available built-in ABIs and their associated interface:

ABI	Interface	Description
OP_20_ABI	IOP20Contract	Fungible tokens
OP_20S_ABI	IOP20SContract	Stable fungible tokens
OP_721_ABI	IOP721Contract	NFTs (Non-fungible tokens)
EXTENDED_OP721_ABI	IExtendedOP721Contract	NFTs (Non-fungible tokens) with minting features
MOTOSWAP_ROUTER_ABI	IMotoswapRouterContract	DEX router
MotoswapPoolAbi	IMotoswapPoolContract	Liquidity pools
MotoSwapFactoryAbi	IMotoswapFactoryContract	Pair factory
MOTO_ABI	IMoto	Moto token

Importing Built-in ABIs

typescript

import {
    // Token ABIs
    OP_20_ABI,
    OP_20S_ABI,
    OP_721_ABI,

    // DEX ABIs
    MOTOSWAP_ROUTER_ABI,
    MotoswapPoolAbi,
    MotoSwapFactoryAbi,
    MOTO_ABI,

    // Staking ABIs
    STAKING_ABI,
    MOTOCHEF_ABI,
} from 'opnet';

Importing Built-in Interfaces

typescript

import {
    // Token interfaces
    IOP20Contract,
    IOP20SContract,
    IOP721Contract,
    IExtendedOP721Contract,

    // DEX interfaces
    IMotoswapRouterContract,
    IMotoswapPoolContract,
    IMotoswapFactoryContract,
    IMoto,
} from 'opnet';

Custom ABIs

Custom ABIs can also be defined for application-specific contracts.

Declaring a custom ABI

typescript

const myAbi = {
    functions: [
        {
            name: 'myMethod',
            inputs: [{ name: 'value', type: 'UINT256' }],
            outputs: [{ name: 'result', type: 'BOOL' }],
        },
    ],
    events: [
        {
            name: 'MyEvent',
            values: [{ name: 'data', type: 'UINT256' }],
        },
    ],
};
