Base token
scanner.

Is it a rug? Find out now. Paste any Base chain token address and this rug checker simulates a real buy and sell on-chain, measures the liquidity and reads the contract, then tells you avoid, caution, or ok — in about two seconds, free, no wallet.

Try it — check a token now

Paste any token address and pick its chain. Real on-chain verdict in ~2s — free, no wallet, no signup.

Free trial — a few checks a day, keyed on your IP; the CLI draws on that same quota. Past that, pay per call: PAYER_PRIVATE_KEY=0x… npx @true402.dev/rugcheck 0x… at $0.01 a report, or wire the API into an agent.

Not a Base token? The same check runs on the BSC token scanner and the Ethereum token scanner — or switch chain in the selector above.

Prefer it in Telegram? Send a token to @True402bot — same on-chain checks, free, and it works while you trade.

§ how it works

Three checks, one verdict.

The check runs a gas-free buy/sell simulation to prove the token can actually be sold (catching honeypots a static scan misses), measures WETH/USDC liquidity depth, and inspects the contract structure — mint functions, active ownership, blacklist and trading kill switches, upgradeable proxies. It returns a single avoid/caution/ok verdict with the reasons behind it.

§ for agents

The same check, in one call.

Wiring this into a trading bot or AI agent is one call: npx @true402.dev/rugcheck 0x… in a terminal, or POST /api/v1/base/token-report over x402 — no account, no API key. See rug-check from your agent, the sniper stack, or the live rug radar.

§ questions

Answered for machines.

Is there a rug checker or token scanner for Base chain?

Yes — this page is one. Paste a Base (chain 8453) token address and it returns an avoid/caution/ok verdict from live on-chain data. Most well-known scanners started on Ethereum, BNB Chain or Solana and treat Base as an afterthought; this one is built for Base specifically, reading Uniswap V3 and Aerodrome pools directly. It is free to try with no wallet and no signup, and the same check is available as a CLI, an HTTP API, and an MCP tool for agents.

How do I check if a Base token is a rug or honeypot?

Paste the token's contract address into the checker on this page. true402 runs an on-chain buy/sell honeypot simulation (can it actually be sold?), checks WETH/USDC liquidity depth, and inspects the contract for mint functions, active ownership, and blacklist/trading kill switches — then returns a single avoid/caution/ok verdict with reasons. It's free to try a few times a day with no wallet; for unlimited checks, use the CLI or the API.

Is this honeypot checker free?

Yes — a few checks per day are free with no wallet or signup (a free trial). Beyond that, the same check is pay-per-call over x402 (~$0.005–0.01 in USDC, no account, no API key): run npx @true402.dev/rugcheck 0x… in a terminal, or POST the token to /api/v1/base/token-report from an agent.

What does the verdict mean?

avoid means the token failed a critical check — typically the sell simulation reverted (a honeypot), there's no real liquidity, or the contract hands the owner a kill switch. caution means it's tradeable but carries risk (e.g. ownership not renounced, thin liquidity). ok means it passed the structural, liquidity, and sell-simulation checks. The verdict always lists the specific reasons.

Can a token pass and still be unsafe?

A passing check means the sell simulation succeeded and none of the structural checks we run found a flag, at that block — it is not investment advice and it cannot predict a future rug (an owner can still pull liquidity later, and an upgradeable proxy can change). Re-check before you trade, prefer renounced-ownership tokens with deep liquidity, and treat the verdict as one input, not a guarantee.
