About

KaiSign is a powerful browser extension that provides clear, human-readable explanations of Ethereum transactions before you sign them.

KEY FEATURES:

Transaction Decoding
- Automatically decodes smart contract function calls
- Shows function names, parameters, and intended actions
- Supports ERC-20, ERC-721, ERC-1155 token standards
- Handles complex multicall and batch transactions

Clear Signing Support
- ERC-7730 compliant metadata integration
- Human-readable intent descriptions
- Recursive calldata decoding for nested transactions
- EIP-712 typed data signature parsing

Protocol Support
- Uniswap Universal Router
- Safe Wallet (Gnosis Safe)
- Aave, Compound, and other DeFi protocols
- Custom protocol metadata via subgraph

Security Features
- Pre-sign transaction analysis
- Token approval warnings
- Contract interaction details
- Transaction history tracking

Privacy First
- All decoding happens locally in your browser
- No private keys or transaction data sent to external servers
- Metadata fetched from decentralized subgraph

HOW IT WORKS:
1. Install the extension
2. Visit any dApp (Uniswap, OpenSea, Aave, etc.)
3. When a transaction is triggered, KaiSign shows a clear explanation
4. Review the transaction details before confirming in your wallet

Perfect for DeFi users, NFT traders, and anyone who wants to understand exactly what they're signing.
