Token Scanners and Rug Checks: What the Tools Can Tell You
Compare RugCheck, GoPlus Security, and Token Sniffer for token risk signals, network coverage, and the limits of automated checks.
In brief
Token scanners inspect selected onchain or contract signals and present them as warnings, scores, or flags. RugCheck focuses on Solana token analysis, GoPlus Security provides security data and APIs for multiple ecosystems, and Token Sniffer scans supported token contracts. These checks can help focus research, but no score proves that a token is safe or predicts whether its price will fall.
What we compared
- Networks and token standards currently supported
- Risk signals exposed, such as permissions, liquidity, holder distribution, or contract properties
- Whether results explain the underlying signal or present a summary score
- Update timing, API availability, and other constraints documented by the provider
The tools
RugCheck
Best for: Automated Solana token checks and risk signals
Solana's token-verification documentation describes RugCheck as an automated analyzer that tracks tokens and evaluates onchain signals such as mint or freeze authority, holder distribution, and liquidity. Its output is one input to research, not a guarantee of safety.
View provider detailsGoPlus Security
Best for: Risk data and security APIs across supported networks
GoPlus documents token-security APIs for supported chains, including EVM networks and a Solana beta API, alongside services for approvals, addresses, phishing, and transaction simulation. Check current network support and interpret each field in the API documentation.
View provider detailsToken Sniffer
Best for: Reviewing token contract checks and an automated audit score
Token Sniffer describes its site as a smart-contract scanner. Its terms say the score measures how a searched token meets criteria for safety. Treat that score as a screening result and read the report and terms before relying on it.

Use scanners to find questions, not to certify a token
We reviewed provider documentation and terms on October 25, 2026. We did not audit the scanners, reproduce their scores, or test their false-positive and false-negative rates. Each service examines a different set of signals, and its coverage can change.
Automated token checks are most useful when a result points to something you can verify. Examples include whether an authority remains enabled, whether a contract is verified, how concentrated holders are, or whether liquidity has restrictions. A green label cannot establish the intent of a token’s creators, ensure that liquidity will remain, or prove that a market will be available when you try to sell.
RugCheck: Solana onchain signals
RugCheck focuses on Solana tokens. The Solana documentation on token verification describes RugCheck as an automated verifier that tracks tokens and analyzes onchain signals, including authorities, holder distribution, and liquidity.
Treat a risk score or status as a pointer to evidence. Open the underlying details and check them against the token mint and current pool. A token can change after a scan, and an automated report may not capture offchain behavior or every way a project can affect trading.
GoPlus Security: APIs for token and transaction risk data
GoPlus Security documents APIs for token security, malicious addresses, approvals, phishing detection, and transaction simulation. Its API overview describes the available services, while the token-security reference lists chain-specific contract-risk fields. The Solana token-security API is marked beta, so developers should confirm its current status and coverage before integrating it.
GoPlus is particularly relevant to app teams that want to consume risk data in their own interface. An API field is not a complete security review: check the definition of each field, the supported chain identifier, request limits, and what happens when a value is unavailable.
Token Sniffer: contract scan and score
Token Sniffer describes its product as a smart-contract scanner. Its terms say its audit score measures how a token meets specified criteria for safety. Read the report behind the score and confirm that the contract address and chain match the asset you are investigating.
A scanner may have less visibility when source code is unavailable or a token uses unusual contract patterns. A score is a screening summary rather than a certification or guarantee. Check the methodology and current coverage before comparing scores from different services.
A practical token check
- Start with the exact address. Search the full token contract or mint, not just the name or ticker.
- Confirm the network. Similar addresses or names can refer to different assets on different chains.
- Inspect evidence, not only a badge. Review permissions, holder concentration, liquidity and pool conditions, and any warnings the scanner exposes.
- Use more than one view. Compare a scanner’s result with the relevant block explorer and the token’s actual market. The tools may rely on different data and update at different times.
- Recheck before acting. Onchain permissions, holders, and liquidity can change. A report is a snapshot, not an ongoing guarantee.
For activity and pool data during token research, see crypto token discovery tools. To inspect a transaction or token address on the ledger, use the block-explorer comparison.
Sources and review scope
We used the Solana token-verification guide, GoPlus API overview, GoPlus EVM token-security reference, GoPlus Solana token-security reference, and Token Sniffer terms. We did not independently validate their detection performance or security guarantees.
