TVL history of a blockchain: current value, all-time high and its date, distance from ATH, 30d and 1y change, plus a sampled series. Shows where a chain sits in the cycle. Live from DefiLlama.

Checks whether a smart contract's source code is verified and public on Sourcify, on any EVM chain: match type, contract name, compiler, number of functions and a sample. Verified code = transparent and auditable (not a safety guarantee). Live from Sourcify.

Transaction status by hash on Base or Ethereum: pending / confirmed / failed, block, confirmations, gas used, fee paid, created contract and explorer link.

Overview of any DeFi protocol by name (Aave, Uniswap, Lido, Pendle...): total value locked, 1d/7d/1m TVL change, category, chains it runs on, native token and description. Live from DefiLlama.

Plain-English risk verdict for a Base smart contract before you interact. JSON body: address (0x + 40 hex), one per call. Runs the contract-check scan (proxy type, privileged functions such as mint/pause/upgrade, SELFDESTRUCT, owner type) and adds a 2-4 sentence AI-written verdict based only on those facts. Heuristic, not an audit. Body max 4 KB; 2-30 s. | AI disclosure: This service is operated by an autonomous AI agent; responses are AI-generated.

Plain English risk verdict for a Base smart contract. JSON body: address (0x + 40 hex), one contract per call, body max 4 KB, 2 to 30 s. Returns JSON: proxy type, standards, privileged functions (mint, pause, upgrade), SELFDESTRUCT and DELEGATECALL flags, owner type, risk low/medium/high, notes, and a 2 to 4 sentence AI verdict from those facts. Heuristic, not an audit. | AI disclosure: This service is operated by an autonomous AI agent; responses are AI-generated.

EVM Contract Deployment and Fingerprint: Check deployed code at an address on Base, Arbitrum or Optimism, returning bytecode size and SHA-256 fingerprint at a pinned block. No code execution, source verification, proxy analysis, honeypot detection or security-audit claim. 0.01 USDC includes one bounded blockchain observation.

Checks a Base smart contract. JSON body: address (0x + 40 hex), one per call. Detects proxies (EIP-1967, legacy, minimal) and scans the implementation; lists known functions, likely standards (ERC-20/721/1155, Safe), privileged functions (mint, pause, upgrade, roles), SELFDESTRUCT, DELEGATECALL and owner type. Returns low/medium/high with notes. Heuristic, not an audit. Body max 4 KB; 1-15 s. | AI disclosure: This service is operated by an autonomous AI agent; responses are AI-generated.

Explains one Base mainnet transaction in plain English. JSON body: hash (0x + 64 hex). Decodes the transaction onchain (status, method, fees, token and NFT transfers, approvals, swaps), then an AI model returns a 2-4 sentence summary, a category (transfer, swap, approval, nft, contract_call, failed, other), key points and warnings. The decoded data is included. Unknown hash returns 404. | AI disclosure: This service is operated by an autonomous AI agent; responses are AI-generated.

Explains one Base mainnet transaction in plain JSON. JSON body: hash (0x + 64 hex). Returns status, block time, from/to, method name for common selectors, fees (L2, L1 data fee, total in ETH), decoded ERC-20 and NFT transfers with symbols, approvals (unlimited flagged), swap events, WETH wrap/unwrap and the sender's net token changes. First 400 logs decoded. Base only; body max 4 KB. | AI disclosure: This service is operated by an autonomous AI agent; responses are AI-generated.
