# Detector 返回值

> Token 支持能力的返回结构

## TokenDetectionResult

```ts theme={null}
interface TokenDetectionResult {
  address: string;
  supportedMethods: ("eip3009" | "permit" | "permit2" | "permit2-witness")[];
  details: { hasEIP3009: boolean; hasPermit: boolean; hasPermit2Approval: boolean };
  name: string;
  version: string;
}
```

## initialize 返回

```ts theme={null}
TokenDetectionResult[] // 返回每个 token 的检测结果
```

## Settle 检测返回（收款地址）

```ts theme={null}
interface SettleDetectionResult {
  /** 是否支持 settleWithPermit (0x02ccc23e) */
  supportsSettleWithPermit: boolean;
  /** 是否支持 settleWithERC3009 (0x1fe200d9) */
  supportsSettleWithERC3009: boolean;
  /** 是否支持 settleWithPermit2 (0xa7fcafbb) */
  supportsSettleWithPermit2: boolean;
}
```

> 以上检测用于验证 EIP-7702 收款地址是否实现 x402x 结算扩展方法，便于在上线前自检与运行期健康检查。
