All projects on Base matching “erc-20”

Base token safety snapshot: heuristic on-chain scan of an ERC-20 on Base (bytecode/proxy check, ERC-20 metadata, risky-function selector scan, owner/renounce check, Uniswap v3 / Aerodrome pool + liquidity discovery, best-effort sell simulation). Public RPC data only. Heuristic, not financial advice.

Base ERC-20 check before an agent buys or holds a token. Input: one contract address. Output: allow, warn, or block. Block: not a contract, not an ERC-20, zero supply, or the owner or token contract holds at least 50 percent. Warn: 20 to 50 percent held, proxy (EIP-1967, EIP-1167, or implementation()), or bytecode contains mint or pause. A selector does not prove the public can call it. Concentrat

Get the ERC-20 token balance of any wallet on Base mainnet. Pass the token contract address and the holder address. Returns the raw balance, decimals, token symbol and the human-readable balance in one JSON response. Works for USDC, WETH, DAI or any standard ERC-20. Read-only, live on-chain data.

Analyze a Base Mainnet token contract: block-pinned owner(), ERC-1967 proxy slots, ERC-20 metadata, code hash, best-effort source match and prior-snapshot comparison when available. Free POST /v1/prepare returns report_id; paid GET /v1/report reads it for 0.01 USDC via x402. Not a security audit.

Ethereum ERC-20 holder concentration from Blockscout: top 100 holders' share of total supply, top 10 share, and a Gini coefficient over those 100 balances. Gini is over the sampled top holders only, not all holders. For the very largest tokens (e.g. USDT) Blockscout can be too slow for the second page of holders; the answer then covers the top 50 (holdersSampled 50, top100SharePct null) and says s

Token safety check for an ERC-20 on Base: is this token a scam, a honeypot, or safe to hold? Examines ownership and mint authority, proxy upgradeability, liquidity and holder concentration, transfer-restriction patterns. Returns hold/caution/avoid with a score and the signals behind it. Heuristic static analysis, not a security audit — a proxy contract can change its implementation after this chec

Token security / honeypot detector for a Base mainnet ERC-20: EIP-1967/1822 proxy + upgradeability detection, bytecode dispatcher scan for mint/pause/blacklist/fee-setter/ownership selectors, owner() renouncement check, and a live eth_call state-override simulation testing whether a synthetic wallet can actually transfer() the token. Returns risk_score (0-100) + verdict (clear/review/block) + huma

Token Price ($0.003): Base token price derived from on-chain state, not a resold price-API feed. Curated majors (ETH, WETH, USDC, DAI, cbETH, cbBTC, BTC) are priced from Chainlink's own Data Feed aggregator contracts on Base; any other Base ERC-20 address is priced from its deepest discoverable Uniswap V3 pool against USDC (with a liquidity read and a low-liquidity flag), or a clean unsupported-to

BNB Smart Chain: Full smart-contract security scan of an ERC-20 token: honeypot, buy/sell/transfer tax, mintable, proxy, hidden owner, self-destruct, pausable, blacklist/whitelist, tax-modifiable, owner and creator share, creator's past honeypots, CEX/DEX listings. GoPlus + honeypot.is simulation merged in one JSON. $0.02 per call.

Check a Ethereum wallet's ERC-20 approvals: allowances for 8 major tokens (USDC, USDT, WETH, DAI...) to common spenders (Permit2, Uniswap Universal Router v4, Uniswap Universal Router, Uniswap SwapRouter02...); flags unlimited approvals.

On-chain Forensics API for AI agents: token verdict cards and settle-safe pre-trade screens ($0.02), ERC-20 burn/mint and wallet forensics ($0.05, Base/Ethereum/XRPL), and $0.25 due-diligence memos. Bare URL = $0.02 directory tier; append ?endpoint=<name> to call a data endpoint

Base ERC-20 risk verdict (OK / CAUTION / AVOID) for $0.01: simulated sell and taxes, top-10 holder share, pool liquidity and age, LP burn, verified source, mint/blacklist functions. Pass a token address.

Is this Base token safe to buy, or a honeypot, rug pull or scam? Send a Base (chainID 8453) ERC-20 contract address and get a pre-trade safety verdict before you swap, snipe, route or approve it: honeypot simulation (can you actually sell it?), buy tax and sell tax, mint and owner privileges, blacklist and pause functions, verified source, holder concentration, live liquidity and 24h volume, plus

Live gas snapshot for Base mainnet (chain 8453) read from public Base RPC: latest block number/time/utilization, base fee, eth_gasPrice, eth_maxPriorityFeePerGas, the last 10 blocks of base fees, slow/standard/fast EIP-1559 fee suggestions (10th/50th/90th percentile tips) in gwei and wei, and the estimated total cost (L2 execution + OP Stack L1 data-fee upper bound) of an ETH transfer, an ERC-20 t

Base token check: send an ERC-20 contract address on Base and get verifiable on-chain facts as JSON (name, supply, owner and whether ownership is renounced, upgradeable proxy, verified source, privileged-function hints such as mint/pause/blacklist, WETH/USDC liquidity on Uniswap V2/V3 and Aerodrome) plus risk flags and a short plain-language summary. Facts only, not financial advice. Does not chec

Returns the native ETH balance and ERC-20 token balances of one Base wallet address, read live from Base mainnet at the latest block: USDC, WETH and the rest of the top 200 Base tokens by market cap, plus up to 50 token contract addresses named in the request. Each row carries the token symbol, name, decimals, raw amount and human-readable amount. Suited to checking a wallet's current holdings bef

List live ERC-20 approvals for a Base (8453) address: token, spender, current allowance, unlimited flag. status ok (complete, approvals found) / none (complete, zero active) / unknown (data incomplete; reason given; never reported as none). Pass ?address=0x... Errors: 400 invalid address; 503 indexer/RPC unavailable (not charged). Read-only; never signs.

Use before buying or approving an unknown ERC-20 token on Base. Rule-based check straight from the chain, without AI - contract and proxy (upgradeable?), owner and whether it was renounced, risky owner functions in the bytecode (mint, pause, blacklist, fees, trading switches), owner share of supply and DEX liquidity on Uniswap V2/V3 and Aerodrome in USD. Returns ok, caution or avoid with reasons i

Did this Base payment settle? Status, block, timestamp and confirmations for one transaction hash, with its ERC-20 Transfers decoded (token, from, to, amount; up to 100 listed, transfers_total gives the full count) and any EIP-3009 authorization used, plus match flags for an optional expected payTo and amount, so an x402 PAYMENT-RESPONSE can be checked. Required: hash. $0.002 USDC on Base. Transac

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.

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

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.

Check Base ERC-20 decimals and total supply at a recorded block, and up to three claims against cited evidence. Returns supported, contradicted, or unknown. Official project coverage currently includes Base USDC only. No safety verdict, liquidity, or holder analysis. One brief costs 0.25 USDC; retain your private Idempotency-Key for recovery.

Token Preflight: pre-trade safety check for a Base ERC-20 (buy/sell simulation, taxes, owner powers, liquidity, LP, holders, verification) with a shareable verdict card. Not investment advice.

One combined go/no-go before an agent spends: PROCEED / CAUTION / ABORT from the token's market verdict, the counterparty wallet's sanctions, age and poisoning check, and — with a spender — its ERC-20 approvals. A leg that cannot be evaluated returns unknown and caps the verdict at CAUTION. Mode 'compact' returns the decision, the worst leg, and one summary per leg. Use this when an agent is about

Everything about a Base transaction in one call: status, time, from and to, ETH value, the function called (for common selectors), the fee split into L2 execution and L1 data in ETH and USD, every ERC-20 transfer with symbol and readable amount, NFT transfers, and x402 payments (USDC transferWithAuthorization) with the seller named from Bazaar.

Base token risk check before a swap: send a token contract address, get ok / caution / avoid with reasons. Reads the contract (ERC-20 metadata, owner, upgradeable proxy, mint / pause / blacklist / fee selectors in bytecode) and its DEX liquidity (Uniswap + Aerodrome pools, read on-chain). Deterministic, no LLM.

Base wallet lookup / address research API: ETH + USDC balance with USD value (CoinGecko/Coinbase quotes), EOA or smart contract, nonce (tx count), gas base fee, ERC-20 token holdings and recent USDC inflows/outflows with counterparty count for any Base mainnet address. Wallet analytics, portfolio and onchain due diligence for agents. Live public RPC reads at request time; pay per call with x402 US

Is this token safe to buy? Honeypot detection, rug-pull and scam check for any ERC-20 token contract -- flags can't-sell traps, hidden mints, malicious buy/sell taxes, unverified source, and holder concentration. GoPlus-powered token security scan with risk score 0-100. Not an audit.

Celo ERC-20 risk check from live chain state. Returns a single verdict (LOW_RISK/CAUTION/HIGH_RISK, summary, oneLiner, reasons) plus market data (DexScreener/GeckoTerminal). Covers owner/renounced, paused, supply, known stablecoins (USDC, USDT, USAT, USDm), proxies (EIP-1967/1822/OZ/1167) with implementation analysis: verified source, risky selectors, upgrade authority (EOA vs Safe/timelock), forw
