# scan.madhousewallet.com

This host is a single-purpose EVM wallet risk scanner targeting agents and applications that need to gate operations on counterparty risk. It serves compliance checks, transaction pre-screening, and off-ramp workflows where a flagged address should block or pause an operation. It is distinct from general blockchain data providers in that it returns an opinionated risk verdict rather than raw on-chain data.

## When to use this host

Use this host when an agent needs a pre-transaction or pre-off-ramp risk check on an EVM wallet address or ENS name and requires a structured verdict (PASS/LOW/MIDDLE/CRITICAL) with a shouldFlag boolean for automated gating. Do not use for non-EVM chains such as Solana or Bitcoin — no equivalent skill exists on this host for those networks. Do not use for continuous or streaming risk monitoring; this host only supports single-shot scans per address. For raw on-chain data without risk scoring, use a general blockchain data provider instead.

## Capabilities

### EVM Wallet Risk Assessment

Scans an EVM wallet address or ENS name for on-chain risk signals and returns a toxic score, risk level classification, and specific flagged metrics to support automated allow/block decisions.

- **`scan-evm-wallet-risk`** — Scans any EVM wallet address or ENS name for on-chain risk signals, returning a toxic score (0–1), risk level (PASS/LOW/MIDDLE/CRITICAL), and flagged risk categories powered by Web3 Antivirus.

## Skill reference

### `scan-evm-wallet-risk`

**Madhouse Wallet EVM Risk Scan** — Scans any EVM wallet address or ENS name for on-chain risk signals, returning a toxic score (0–1), risk level (PASS/LOW/MIDDLE/CRITICAL), and flagged risk categories powered by Web3 Antivirus.

*Use when:* Use when an agent needs to assess the risk profile of an EVM wallet address or ENS name before processing a transaction, off-ramp, or compliance check — especially when a shouldFlag=true result should block the operation.

*Not for:* Do not use for non-EVM chains (e.g., Solana, Bitcoin). Not suitable for real-time streaming risk monitoring; this is a single-shot scan per address.

**Inputs:**

- `address` (string, required) — EVM wallet address (0x-prefixed, checksummed) or ENS name to scan.

**Returns:** Returns address, toxicScore=0, riskLevel=PASS, shouldFlag=false, flaggedMetrics=[], and ens=null for a clean wallet; non-zero scores include populated flaggedMetrics with named risk categories.
