All projects on Base matching “calldata”

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.

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

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

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

Ready-to-sign, already-simulated Aero allocate() transaction for an sAERO position: the best split of Base gauges for its size (fees plus incentives, after its own dilution) as unsigned calldata for the Voter, with the cooldown, expected USD per day versus now, and warnings. Handles the contract's rules (full overwrite, exact total, ascending addresses, idle power). Never signs or sends. Base only

Builds a gas-optimized multi-recipient payout plan: either a list of native transfers or a single Multicall3 aggregate3 batch of ERC20 transfer() calls. Returns calldata only - this service never signs or broadcasts.

Use when an agent must choose where to lend or borrow: supply and borrow APY on Aave, Compound and Morpho. DeFi lending rates: supply and borrow APY on Aave V3, Compound V3 and Morpho by chain and asset, with a best stablecoin rate view (chainpeek, Tanod).

Cross-exchange spread tick — ONE $0.02 call returns the live executable spread for a pair across Binance, Coinbase, Kraken, Bybit: best bid venue, best ask venue, spread in bps, and a deterministic TRADE / THIN / NONE verdict. Built for arbitrage monitoring loops; escalate to /api/crypto ($0.07) for the full CEX arbitrage read with fees and transfer paths. 30s freshness, no LLM in the path.
