# BCkit

> Blockchain developer toolkit — debug smart contracts faster.

BCkit is a free collection of web-based tools for Ethereum and EVM-compatible blockchains. No account required.

## Tools

- [Decoder](https://decode.bckit.cc): Decode and encode Ethereum calldata, look up function signatures by 4-byte selector, and convert Unix timestamps. Supports Safe multi-send decoding.
- [Sneak Peek](https://sneakpeek.bckit.cc): Connect to any dApp as any Ethereum address without owning the private key. Capture transactions, decode calldata, and simulate with Tenderly. Supports WalletConnect, iFrame, and browser extension.
- [Allowance Manager](https://allowance2.bckit.cc): Review and revoke ERC-20 token approvals across multiple EVM chains. Protect your wallet by managing smart-contract allowances.
- Inspector (coming soon): Explore contract storage, state diffs, and internal calls.
