defi-shield-hazel.vercel.app
DeFi Shield serves agents that need to gate-check DeFi actions before committing funds or forwarding instructions. It covers the full pre-interaction surface: screening addresses, domains, query strings, and text for injection or fraud; assessing MEV and liquidity risk; comparing chains and bridge routes; and decoding on-chain events. It is distinct from price-feed or DEX-routing hosts — its value is risk intelligence, not market data or transaction execution.
Capabilities
Address & Identity Resolution
Resolves blockchain addresses to human-readable labels and trust classifications, enabling agents to identify counterparties before interacting with them.
fetch-address-labelfetch-defi-trust-scoreverify-agent-trust
Wallet & Protocol Risk Assessment
Produces comprehensive risk profiles for EVM wallets and DeFi tokens, covering on-chain history, holdings, honeypot detection, contract risk, and holder analysis.
fetch-wallet-full-reportrun-defi-pre-trade-check
MEV & Trade Safety
Evaluates MEV exposure, sandwich attack probability, price impact, and gas costs on Base L2 before a trade is submitted, enabling agents to set safe slippage and timing.

Cross-Chain Infrastructure
Provides chain comparison, L2 finality parameters, yield opportunities, and bridge route quotes to support multi-chain deployment and asset-movement decisions.

Market Regime & Macro Context
Classifies the current DeFi market regime (BULL/BEAR/NEUTRAL) with confidence scores and signal metrics to inform strategy sizing and entry/exit decisions.
classify-defi-market-regime
Domain & Data Source Integrity
Screens external URLs and domains for phishing risk, SSL validity, and HTTP-layer data freshness before an agent relies on them for pricing or oracle reads.
check-domain-reputationcheck-defi-data-freshness
Input & Query Security
Detects prompt-injection attacks in user-supplied text and SQL/contract-call injection patterns in DeFi query strings before they reach an LLM or protocol endpoint.

On-Chain Event Decoding
Decodes raw EVM event log topics and data against a provided ABI into structured, human-readable fields for downstream analysis or display.

Software Supply Chain Security
Scans named software packages for CVEs, prototype pollution, and supply-chain threats, returning a risk score and recommendation before a dependency is adopted.

Workflows
Pre-Trade Safety Gate
Use when an agent needs to fully vet a DeFi token trade before execution, covering counterparty trust, MEV exposure, price impact, and gas cost in sequence.
- 1fetch-defi-trust-scoreScore the token contract address to confirm it is not a known malicious or unclassified protocol.
- 2run-defi-pre-trade-checkRun honeypot, contract, holder, and liquidity checks on the token to get a pre-trade verdict and overall risk score.
- 3assess-mev-riskEvaluate sandwich attack probability and recommended slippage for the trade size on the target chain.
- 4analyze-mev-price-impactEstimate price impact percentage and effective price to confirm the trade size is safe relative to pool liquidity.
- 5fetch-mev-gas-oracleRetrieve current Base L2 gas prices and USD cost estimates to price the transaction before submission.
Counterparty Due Diligence
Use when an agent needs to assess the trustworthiness of an unknown EVM wallet or contract before sending funds, delegating authority, or entering a protocol interaction.
- 1fetch-address-labelResolve the address to a human-readable label and category to determine if it is a known EOA, contract, or service.
- 2verify-agent-trustCheck the address trust score, classification, and flags for on-chain behavioral signals.
- 3fetch-wallet-full-reportPull the full on-chain wallet report including transaction history, token holdings, DeFi activity, and security flags for a complete risk picture.
Safe DeFi Site Interaction Check
Use when an agent needs to verify that a DeFi website and its data endpoints are legitimate and returning fresh data before a user connects a wallet or the agent reads oracle values.
- 1check-domain-reputationScore the domain for phishing risk, SSL validity, and security headers to confirm it is not a fraudulent site.
- 2check-defi-data-freshnessInspect the HTTP-layer freshness of the site's data endpoint to confirm price feeds or oracle URLs are not stale.
Cross-Chain Bridge Decision
Use when an agent needs to select the safest and most cost-effective chain and bridge route for moving assets, accounting for finality risk and yield opportunities at the destination.
- 1compare-blockchain-networksRank candidate destination chains by TVL, finality time, and composite score to identify the best target chain.
- 2fetch-l2-finality-statusRetrieve the finality parameters (challenge period, sequencer details, data availability) for the chosen L2 destination.
- 3fetch-cross-chain-bridge-quoteCompare bridge route options with fee estimates, transfer times, and trust models for the selected chain pair.
- 4fetch-crosschain-yieldCheck available yield pools on the destination chain for the token to evaluate post-bridge deployment opportunities.
Agent Input Security Screening
Use when an agent needs to sanitize external or user-supplied inputs before passing them to an LLM or forwarding a query to a DeFi protocol endpoint.
- 1detect-prompt-injectionScreen the raw text input for prompt-injection patterns and flag any suspicious segments before LLM processing.
- 2query-defi-safety-assessmentAnalyze the DeFi query string for SQL or contract-call injection vulnerabilities before forwarding to a protocol.

Own defi-shield-hazel.vercel.app? List it with your agent
Paste the prompt below to your coding agent. It runs a real paid test on every route, fixes what scores low, and re-auditions until they pass — the gaps below are already filled in for you.
- 4 routes are scoring below 50 — likely broken, mispriced, or returning the wrong shape.
- 39 routes are in the 50–74 band — working, but with room to climb.
- 27 routes are flagged by the verifier as failing or inconclusive.
Paste this to your agent
Make my x402 API at https://defi-shield-hazel.vercel.app discoverable on x402gle. Read the instructions at https://x402gle.com/agent.md and follow them end to end. Install the OpenDexter CLI, then run `npx @dexterai/opendexter audition https://defi-shield-hazel.vercel.app --json`. Heads up: 4 routes are scoring below 50 — start there. Read the score and fixInstructions for every route, fix my OpenAPI and endpoints until each route passes, and re-audition until it does. A passing audition lists my API automatically.
