查询支持的权限类型

使用 wallet_getSupportedExecutionPermissions 获取 TokenPocket 当前支持的权限类型、适用链 ID 及可绑定的规则类型。建议在发起授权前调用，避免请求不支持的 permission.type 或 chainId。

RPC 方法

wallet_getSupportedExecutionPermissions

请求

const result = await provider.request({
  method: "wallet_getSupportedExecutionPermissions",
  params: [],
});

响应结构

type GetSupportedExecutionPermissionsResult = Record<
  string, // permission type
  {
    chainIds: `0x${string}`[];
    ruleTypes: string[]; // 如 ['expiry']
  }
>;

响应示例

{
  "erc20-token-periodic": {
    "chainIds": ["0x1", "0x38", "0x89"],
    "ruleTypes": ["expiry"]
  },
  "native-token-periodic": {
    "chainIds": ["0x1", "0x38"],
    "ruleTypes": ["expiry"]
  },
  "erc20-token-stream": {
    "chainIds": ["0x38", "0x89"],
    "ruleTypes": ["expiry"]
  },
  "native-token-stream": {
    "chainIds": ["0x38"],
    "ruleTypes": ["expiry"]
  }
}

以上为示意结构，实际返回值以钱包版本与链配置为准。

能力探测示例

在发起授权前校验目标链与权限类型：

const toHexChainId = (id: number) => `0x${id.toString(16)}` as `0x${string}`;

async function assertPermissionSupported(
  provider: {
    request: (args: { method: string; params: unknown[] }) => Promise<unknown>;
  },
  permissionType: string,
  chainId: number,
) {
  const supported = (await provider.request({
    method: "wallet_getSupportedExecutionPermissions",
    params: [],
  })) as Record<string, { chainIds: string[]; ruleTypes: string[] }>;

  const entry = supported[permissionType];
  if (!entry) {
    throw new Error(`钱包不支持权限类型: ${permissionType}`);
  }

  const chainHex = toHexChainId(chainId).toLowerCase();
  const supportedChains = entry.chainIds.map((id) => id.toLowerCase());

  if (!supportedChains.includes(chainHex)) {
    throw new Error(`权限 ${permissionType} 不支持 chainId ${chainId}`);
  }

  return entry;
}
