v0.1.0-alpha.0

First public alpha of txKit. API may change before v0.1.0 stable.

Packages

• @txkit/core - framework-agnostic types and utilities
• @txkit/react - React components: ConnectWallet, TokenBalance, TransactionButton, FlowSteps, FlowProgress, FlowToast
• @txkit/themes - CSS themes (light/dark, soft/sharp/rounded variants)
• @txkit/tx-protocol - PreparedTransaction envelope (CAIP-2, EIP-5792 aligned, ERC-7730 clear-signing)
• @txkit/tx-decoder - calldata decoder with ERC-7730 registry support
• @txkit/ows-adapter - bridge to MoonPay Open Wallet Standard
• @txkit/x402-adapter - bridge to x402 HTTP payments

Anti-phishing patterns built in

• Pre-sign transaction simulation through eth_call
• Decoded calldata in human-readable form
• Bounded approvals by default (no MAX_UINT256)
• Address-poisoning detection
• Risk-provider slot ready for Blowfish / Blockaid integration
• Confirmation friction with countdown on flagged operations

Install

npm install @txkit/react@alpha @txkit/themes@alpha viem wagmi @tanstack/react-query

Coexistence

txKit works alongside RainbowKit, AppKit, and ConnectKit through a shared
wagmi config. RainbowKit owns the connect modal, txKit owns the
transaction UX. See embedded mode in the docs.

Known limitations

• ENS resolution requires mainnet (testnet preset injects mainnet for lookups)
• CSS-only theming (no runtime theme API yet)
• No SSR helpers; relies on wagmi ssr: true + cookieStorage
