TransactionKit

TransactionKit is a framework-agnostic React library developed by Etherspot designed to simplify blockchain transaction management for Web3 developers. It enables developers to integrate modular smart accounts into their dApps with minimal code, providing advanced features such as transaction batching, cross-chain support across 22+ EVM-compatible chains, and gasless or sponsored transactions. This allows users to execute multiple transactions in a single click, onboard seamlessly across multiple blockchains, and pay gas fees using various stablecoins or have the dApp sponsor the fees entirely.

The library supports two wallet modes: Modular mode, which leverages Etherspot's Modular SDK for smart account functionality requiring a wallet provider, and Delegated EOA mode, which supports EIP-7702 delegated externally owned accounts using a private key without needing a provider. TransactionKit offers a fluent, method-chained API with full TypeScript support, error handling, and debug logging. It is framework agnostic, compatible with React, Vue, Angular, vanilla JS, React Native, and Node.js environments.

What sets TransactionKit apart is its comprehensive multi-chain batching capabilities that intelligently group transactions by chain, reducing user friction when interacting with multiple blockchains. It also supports gasless transactions and flexible bundler configurations for custom API endpoints. The library provides utilities for transaction estimation, sending, updating, and removal, as well as advanced account and client management methods. Developers can get started quickly with simple installation commands and example code, and benefit from detailed documentation and active community support via Discord.
