# trust_check_wallet

Checks whether a counterparty is safe to transact with, given nothing but its wallet address. Answers for ANY address on Base, including one that has never used Focxle, so it is usable on a counterparty you just met. Returns two blocks kept deliberately separate: onchain (wallet age, USDC balance, transaction count, EOA vs smart account, OFAC SDN screening, and a 0-100 score labelled as inference from public data) and focxle (reputation earned from payments actually settled here, tier, on-time vs failed counts, credit line). Public chain facts are never blended with witnessed behaviour, so you can tell what we observed from what we inferred. Costs $0.02 in USDC. Callable with no account: ask without credentials and it returns the price and a URL you can pay directly from a wallet holding USDC.

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "trust_check_wallet",
    "arguments": {
      "wallet": "<wallet>"
    }
  }
}
```

## Why trust_check_wallet is rated Low

This is fundamentally a read operation that queries and returns blockchain and reputation data without side effects. While the data informs financial decisions on a Financial OS platform, the tool itself performs no financial transactions, does not execute code, and does not modify state.

From the tool's own definition: "Tool description states it 'Checks whether a counterparty is safe to transact with' and 'Returns two blocks': onchain data (wallet age, balance, transaction count, OFAC screening, score) and focxle reputation data (tier, payment history, credit line)."

## Use case

AI agents call trust_check_wallet to retrieve information from AFOS — Agentic Financial OS without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches AFOS — Agentic Financial OS:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "trust_check_wallet": {}
  }
}
```
