Implementation Reference

• src/zetrix-sdk.ts:270-286 (handler)

  Core implementation of getNonce that wraps the official zetrix-sdk-nodejs SDK's account.getNonce method.

  async getNonce(address: string): Promise<number> {
    await this.initSDK();
  
    try {
      const result = await this.sdk.account.getNonce(address);
  
      if (result.errorCode !== 0) {
        throw new Error(result.errorDesc || `SDK Error: ${result.errorCode}`);
      }
  
      return result.result.nonce;
    } catch (error) {
      throw new Error(
        `Failed to get nonce: ${error instanceof Error ? error.message : String(error)}`
      );
    }
  }

• src/index.ts:1181-1194 (handler)

  MCP server handler for the tool that extracts arguments and calls ZetrixSDK.getNonce.

  case "zetrix_sdk_get_nonce": {
    if (!args) {
      throw new Error("Missing arguments");
    }
    const nonce = await zetrixSDK.getNonce(args.address as string);
    return {
      content: [
        {
          type: "text",
          text: JSON.stringify({ address: args.address, nonce }, null, 2),
        },
      ],
    };
  }
