@tokenbound/sdk

An SDK for interacting with ERC-6551 accounts using viem.

Installation

$ npm install @tokenbound/sdk

Usage

Instantiate TokenboundClient

Using viem's WalletClient:

import { TokenboundClient } from "@tokenbound/sdk";
import { goerli } from 'viem/chains'
const tokenboundClient = new TokenboundClient({ walletClient, chainId: goerli.id });

or, with a legacy Wagmi / Ethers signer:

import { TokenboundClient } from "@tokenbound/sdk";
const tokenboundClient = new TokenboundClient({ signer, chainId: 1 });

Get account address

import { TokenboundClient } from "@tokenbound/sdk";
import { goerli } from 'viem/chains';
const tokenboundClient = new TokenboundClient({ walletClient, chainId: goerli.id });

const tokenBoundAccount = tokenboundClient.getAccount({
  tokenContract: "<token_contract_address>",
  tokenId: "<token_id>",
});

Encode call to account

import { prepareExecuteCall } from "@tokenbound/sdk";

const to = "0xe7134a029cd2fd55f678d6809e64d0b6a0caddcb"; // any address
const value = 0n; // amount of ETH to send in WEI
const data = ""; // calldata

const preparedCall = await tokenboundClient.prepareExecuteCall({
  account: "<account_address>",
  to: "<recipient_address>",
  value: value,
  data: data,
});

// Execute encoded call
const hash = await walletClient.sendTransaction(preparedCall);

Custom Implementations

The SDK supports custom 6551 implementations.

If you've deployed your own implementation, you can optionally pass custom configuration parameters when instantiating your TokenboundClient:

import { TokenboundClient } from "@tokenbound/sdk";

const tokenboundClient = new TokenboundClient({
    signer: <signer>,
    chainId: <chainId>,
    implementationAddress: "<custom_implementation_address>",
})

// Custom implementation AND custom registry (uncommon for most implementations)
const tokenboundClientWithCustomRegistry = new TokenboundClient({
    signer: <signer>,
    chainId: <chainId>,
    implementationAddress: "<custom_implementation_address>",
    registryAddress: "<custom_registry_address>",
})
