All projects on Base matching “optimization”

Crypto token rug-pull and junk-risk check for Base, Ethereum, BNB Chain, Arbitrum, Polygon, Optimism, Avalanche and Solana. Send a token contract address or Solana mint; get a grade (JUNK, RISKY, CAUTION, CLEAN), a 0-100 risk score and red flags: honeypot, sell tax, mint/freeze authority, owner powers, holder concentration, liquidity, pool age. Not financial advice. Free sample: https://nojunk-tok

Native gas on Ethereum, Arbitrum, Base, BNB Chain, Polygon or Optimism, paid in USDC on Base, Arbitrum or Polygon. Offers come from /x402/gas/quote for the chains, a recipient and a USDC amount. The payment goes to an address made for that one order, which delivers at least the stated minimum in native; from another chain, USDC on arrival if the arrival swap fails. An order not executed by its dea

Agent Margin Router – Gas Fees: Live EIP-1559 gas fees (slow/standard/fast tiers) plus USD cost per transaction type (transfer, ERC-20 transfer, swap, NFT mint) for Base, Ethereum, Arbitrum, Optimism and Polygon. Aggregated from public RPC nodes – no API key. Pay per call with USDC or USDT on Base via x402. 3 free calls per wallet.

Validate and standardize a delivery address: parsing, provider verification (US-optimized), geocoding and a deliverability score, as JSON. 0.02 USDC per call on Base. Useful before shipping to or storing an address.

Live gas price on Ethereum, Base, Arbitrum, Optimism or Polygon, in gwei plus the cost of a plain transfer. Compare several chains in one call.

JSON-RPC read access to EVM chains (base, ethereum, polygon, arbitrum, optimism) with no API key. Send a standard JSON-RPC body (eth_call, eth_getBalance, eth_blockNumber, eth_getLogs). Also callable as GET with the same fields as query parameters.

JSON-RPC read access to EVM chains (base, ethereum, polygon, arbitrum, optimism) with no API key. Send a standard JSON-RPC body (eth_call, eth_getBalance, eth_blockNumber, eth_getLogs). Also callable as GET with the same fields as query parameters.

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.

Live Chainlink price for ETH, BTC, LINK, USDC, USDT, DAI, SOL, AAVE, UNI, stETH, cbETH, ARB, OP, POL or BNB in USD, read with latestRoundData() from verified aggregator contracts on ethereum, base, arbitrum, optimism, polygon and bsc. Omit chain to read every chain that has the pair and get the median, the cross-chain spread and each feed's age in seconds (to apply your own staleness limit), round

DeFi-Yield Cross-Chain DeFi Yield & Stablecoin APY Radar: Scans risk-adjusted DeFi lending and vault APYs across Base, Arbitrum, Optimism, and Polygon.

Stop opening five explorers to price one transaction: one GET returns what each chain is charging for gas right now — for base, eth, arbitrum, optimism and polygon: the current gas price in gwei (with the raw wei the RPC returned), the latest block's base fee, the priority fee a 50th-percentile transaction actually paid across the last five blocks, the next block's base fee under the EIP-1559 form

ERC-20 token safety pre-check from on-chain data only (Base, Ethereum, Arbitrum, Optimism, Polygon, BSC): name/symbol/decimals/supply, owner and whether renounced, EIP-1967/minimal proxy detection, and a bytecode scan (incl. implementation) for mint, blacklist, adjustable-fee, max-tx, trading-switch and pause functions, with flags and a risk level. Run before swapping into an unknown token. $0.005

Bin-packing heuristic — deterministic best-fit-decreasing capacity planning for placing items into bins, with feasibility evidence and an honest volume bound.
