All projects on Base matching “evm”

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

Read-only EVM state API for wallet snapshots, ERC-20 balances, token allowances, contract code, block heights, and bounded eth_call reads across Ethereum, Base, Arbitrum, Optimism, and Polygon. Fixed price: $0.15 USDC on Base for a batch of up to 100 checks. Only submitted checks run. Results are provider-reported RPC data, not cryptographic proofs.

Multi-chain EVM gas price oracle for AI agents — 17 chains (Ethereum, Base, Arbitrum, Optimism, Polygon, BNB, Avalanche…). One x402 call returns slow/standard/fast EIP-1559 tiers as DROP-IN maxFeePerGas + maxPriorityFeePerGas in wei (plug straight into a viem/ethers tx, no conversion, exact even on sub-gwei L2s), plus base fee, head block, and fullness, from a live eth_feeHistory call. Pass ?chain

Onchain-Risk EVM & Solana Honeypot & Rug Scanner: Audits token contracts across Base, Ethereum, Arbitrum, and Solana for rug-pull vectors.

Use this before adding or upgrading an npm dependency (OpenZeppelin, solmate, hardhat…), or to triage a lockfile: GitHub/OSV advisories affecting a whole package-lock.json or yarn.lock (or up to 100 listed packages) at their exact pinned versions. Instant, per request.

Screen one address (EVM, Bitcoin, Tron, Solana, Polkadot, Cosmos or WAX as wax:account) against the OFAC SDN list, Tether/Circle freezes (EVM, Tron, Solana) and public C3 reports. Returns action BLOCK (OFAC SDN match), REVIEW (reported or frozen; current freeze = HIGH) or ALLOW_NO_REPORTS, riskScore, riskLevel, sanctions, freezes, reports, related domains, co-occurring addresses. NONE_REPORTED mea

MioDio Meridian Aave v3 risk card for an EVM address: health factor, collateral, debt and liquidation distance (~$0.005 USDC Exact on Base). Use before acting on an EVM address to read its Aave v3 health factor, collateral and debt. Errors: 400 invalid_address or unsupported_chain (chain must be base or ethereum), 402 payment required, failed upstream reads return 200 with status partial/error (un

Address security check — detect malicious wallets, known phishing addresses, scam contracts, and blacklisted entities across all EVM chains. Chain-independent lookup against multi-chain security databases. No API keys needed. Accepts USDC payments on Base and Solana

Produce a factual snapshot of current x402 payment authority for one unpaid v2 requirement and one public EVM payer: selected scheme/network/asset/amount/payTo/transfer method, same-block token balance, canonical token-spender allowance when that path applies, and declared recovery-path classification. Does not sign, approve, construct a transaction, judge native gas, or recommend whether to buy.

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

FOMO's best traders for the period (24h, 7d, 30d or all time), best first. Each entry is the trader's profile (handle, user id, Solana and EVM wallets, picture, follower and trade counts, top holdings) plus rank and pnl for the period (also in FOMO's field pnl24h, pnl7d, pnl30d or totalPnL). This is all FOMO publishes: 150 entries per period, 100 all-time, no paging. Ranks beyond that are per user

Crypto wallet sanctions check (OFAC): is this blockchain address on the US Treasury OFAC sanctions lists? Exact match against all 1,000+ digital currency addresses OFAC publishes on SDN and Consolidated entries (Bitcoin, Tron, Ethereum and EVM chains, USDT, Litecoin, Monero and more), returning the listing's program and entry ID. Use before sending or accepting a crypto payment. No tracing or risk

Screen an EVM wallet or contract address BEFORE paying it. Deterministic, keyless compliance / safety gate: checks the address against the OFAC sanctioned crypto-address list and a curated taint set (mixer, hack, scam) and returns a single BLOCK / REVIEW / ALLOW recommendation plus the matched sources, so an AI agent can decide whether to send funds. No API keys, no LLM, one x402 USDC micropayment

Verdix: call before an agent sends funds to an EVM address on Base. Returns safe/caution/danger with reasons from OFAC sanctions, scam/phishing lists, address-poisoning lookalikes, burn-address and contract/deployer checks; quick adds address age, standard/deep on-chain behaviour. "safe" is not a guarantee. Legacy route that sells 3 tiers (a default client buys quick); new integrations should call

SECONDED checks EVM transactions, permits, tokens, agent registrations and suspicious messages before you sign or act. Two rival-lab models must agree; NOT VERIFIED means pause or ask a human. Choose a product and submit its exact input. A paid answer is a signed check, not a guarantee.

Is this transaction, approval or signature safe to sign? Check it before your AI agent or wallet signs it: pre-sign verdict (green/orange/red + reason codes) for EVM and Solana transactions, token approvals and Permit/Permit2/EIP-3009/Seaport signatures. Screens the spender or recipient wallet for OFAC sanctions and scam, phishing or theft reports, and flags unlimited allowances, plain-wallet spen

Smart contract security and token risk check before you trade, approve, bridge or integrate: deterministic 0-100 risk score for any deployed contract on 20 EVM chains. Flags rug-pull levers (owner mint, blacklist, pause, adjustable fees, upgradeable proxy, ownership not renounced), SELFDESTRUCT/DELEGATECALL, verified source and aderyn static analysis. Read-only. Errors (400 bad input, 422 not a co

Get live EVM gas pricing with EIP-1559 breakdown and USD cost estimates

Decode what an EVM payment authorization actually authorizes before signing.

NoJunk Chain tx: Transaction hash -> status, from/to, value, gas used, fee, confirmations and decoded ERC-20 transfers (EVM); Bitcoin tx with inputs/outputs; Solana tx with signers, programs and balance changes.

Wallet sanctions check for a validated EVM or Solana address. Returns a direct verdict, recommended action, match evidence, source lists, and an explicit AML-scope caveat.

Screen an EVM wallet address by exact match against the digital currency address identifiers on the official US Treasury OFAC SDN List (validated snapshot, refreshed hourly). Returns a signed listed / not_listed result with the SDN entry, dataset provenance and limits. SDN only, not EU/UN/UK lists; a non-match is not legal clearance. For payment screening before sending funds.

Real-time at-risk DeFi borrowers across Aave V3, Morpho, Comet, Euler V2, Fluid, Moonwell, Spark on 11 EVM chains. Returns health factor, collateral, debt, and protocol. Updated every 5 minutes from the liquita liquidation engine.

Checks whether a signature was made by a claimed EVM address: EIP-191 personal_sign messages, EIP-712 typed data or a raw 32-byte digest, verified by ecrecover for wallets or ERC-1271 isValidSignature for smart-contract wallets (Safe, Coinbase Smart Wallet) on Ethereum, Base, Arbitrum, Optimism or Polygon. Returns validity, method, recovered signer and digest. Free sample: https://onchain-health.m

Honeypot check, rug check and token safety check: is this token safe or a scam? Token verdict (safe/caution/danger), 0-100 token risk score and reasons.
