TransactionKit
A React library by Etherspot that simplifies Web3 development with transaction batching, cross-chain UX, and gasless transactions.
Overview
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.
The Problem
Developers face complexity integrating multi-transaction workflows, cross-chain support, and gas fee management into Web3 applications. Managing multiple transactions, chains, and user signatures often leads to poor user experience and increased development overhead.
The Solution
Key Features
Transaction Batching and Naming
Compose multiple transactions into named batches for single-click execution and easy management.
EIP-7702 Delegated EOA Support
Native support for delegated externally owned accounts with delegation and undelegation methods.
Flexible Bundler Configuration
Customize bundler URLs and API key formats for integration with different backend services.
Comprehensive Client and Account Management
Access underlying wallet, public, and bundler clients for advanced operations and state management.
Key Strengths
How Developers Use TransactionKit
Cross-Chain dApp Onboarding
Developers use TransactionKit to onboard users from over 22 EVM-compatible chains with a unified interface, simplifying wallet interactions and reducing friction.
Gasless Transaction Experiences
dApps implement gasless or sponsored transactions allowing users to pay fees in stablecoins or have the dApp cover gas, improving user retention and conversion.
Batching Multiple Transactions
Developers bundle multiple related transactions into a single batch to streamline complex workflows like NFT minting or DeFi operations.
