Products & Capabilities

Everything SpotBlock offers, in one place: check an address against our scam database, run a deep AI or vulnerability scan when in doubt, monitor wallets and contracts in real time, or integrate the Threat Check API into your dapp, wallet, or backend.

Main capabilities

Scam check

Fast

Instantly check if an address is flagged by the SpotBlock scam database and scanner.

Paste any wallet or contract address. If it's not flagged but you have a doubt, escalate to a scan.

AI Deep Scan

Deep

Get a detailed AI verdict on whether a contract is malicious, with evidence and scoring.

Paste a contract address. Requires a connected wallet to sign the scan request in Explorer.

Vulnerability Scan

Deep

Scan a smart contract for vulnerability issues and risky patterns.

Paste a contract address. Requires a connected wallet to sign the scan request in Explorer.

Real-Time Monitoring

Live

Watch any wallet or contract and get notified the moment something important changes, so you can respond before it becomes a loss. Built for teams and users who need to act fast.

SpotBlock AI

spotblock.aiExploration phase

Our research arm explores what SpotBlock's threat data makes possible — on top of 140k+ flagged contracts, 129k+ scanner decisions and 16k+ human verdicts.

  • Threat-intelligence feeds — fresh, labeled scam families, deployer clusters and funding-taint chains
  • Labeled datasets — 16k+ human verdicts and 900+ labeled findings, structured for ML on smart-contract security
  • Fine-tuned detection models — contract-risk classification built on the labeled corpus, measured per class
  • Benchmarks — reproducible per-class precision for smart-contract security models
  • LLM-assisted research — detector drafting, invariant and fuzz-harness generation paired with static analysis
  • Graph analytics — funding-taint tracing, actor clustering and mimic detection via bytecode embeddings

Possibilities, not commitments — nothing here is for sale yet.

Tx Harm API

Live

Analyze any transaction — mined or just-signed — for threat-DB involvement, token transfers, and internal calls before you trust it. Also available via MCP, OpenAPI, and llms.txt.

Developer utilities

Lightweight helpers for everyday on-chain work.

Wallet Checker

Validate an address profile before trust: balance, activity, and whether it is a contract.

Broadcast Signed Transaction

Broadcast only when you have verified the payload and destination; this helps enforce sign-then-review flow.

ENS Resolver

Resolve names and addresses to reduce copy/paste errors and detect suspicious lookalike identities.

Sepolia Faucet

Test safely on Sepolia first so risky transaction patterns are caught before you move to mainnet.
