A simple tx hash to readable function call decoder using rust.rs

Decode raw EVM transaction calldata into human-readable function calls — selector resolution via 4byte.directory + built-in signatures

Read any Ethereum, BNB Chain or Solana transaction in plain English. Runs entirely in the browser, no backend.

ERC-7730 SDK - Decode blockchain transactions into human-readable format for clear signing

Decode a Base transaction: what it actually did on chain, in plain English. For when your system and the chain disagree — was the transfer made, did the call settle. Returns JSON: assets moved, counterparties, risk flags, and which checks actually ran, gas in USD. Free tier, then $0.02/call via x402. MCP or HTTP.
