Real-time on-chain crypto bounty radar: scans on-chain ERC-8183 escrow contracts and web3 agent bounty platforms for verified, funded reward opportunities and agent task enrichments on Base ($0.75 USDC). Input: query or chain parameter.

Strict Solidity ABI calldata decoder — decode canonical EVM smart-contract function calls or typed values, verify selectors, and reject ambiguous offsets or padding.

Simulate an EVM transaction before signing. Decodes the calldata into a named function with arguments and security risk flags, AND runs a keyless static eth_call preview to tell you whether the transaction would succeed or revert (with the decoded revert reason). Use it to catch a failing or malicious transaction before you broadcast it. Read-only, no keys, no node infra. Asset-level change tracin

Simulate one unsigned Base transaction before an agent signs it. Runs eth_call and gas estimation on current chain state, decodes the intent (ERC-20 transfer, approve, NFT setApprovalForAll), flags unlimited approvals, calldata sent to a non-contract, zero-address targets, reverts and destination risk labels such as phishing or sanctions. Returns ALLOW, WARN, BLOCK or INCOMPLETE with findings. No

Get the verified Solidity/Vyper source code for a deployed contract by address, sourced from Sourcify. Returns every source file (path + content), the contract name, language, compiler version and compiler settings (optimizer, evmVersion) — the full human-readable source an agent needs to read, audit or feed to an LLM. Supports Ethereum, Base, Arbitrum, Optimism, Polygon. Unverified contracts retu
