    accountName := "Bob"
    seed := "17673b9a9fdec6dc90c7cc1eb1c939134dfb659d2f08edbe071e5c45f343d008"
    c, err := sdk.NewClient(accountName, seed) 	 
    if err != nil { panic(err) }
    
    result, err := c.WithdrawNft(nftId)
    if err != nil { panic(err) }
    
    data, _ := json.Marshal(result)
    fmt.Println("WithdrawNft:", string(data))
}

Example result

WithdrawNft: {"success":true}

Javascript

Example

• Withdraw NFT with NftId = 6

  1. Initialize the client

  2. Withdraw the NFT

With the private key:

import { Client } from "@zecrey/zecrey-legend-js-sdk";

const account_name = "amber1.zec";
const seed = "ee823a72698fd05c70fbdf36ba2ea467d33cf628c94ef030383efcb39581e43f";

const client = new Client(account_name, seed);
await client.initialize();

const nft_id = 48;
const to_address = "0x09E45d6FcF322c4D93E6aFE7076601FF10BA942E";
const res = await client.withdrawNft(nft_id, to_address);

console.log("success: ", res);

With the wallet:

import { SDK } from "@zecrey/zecrey-legend-js-sdk";

const sdk = new SDK();
await sdk.initial();

const account_name = "Alice.zec"; // sender's account name
const account_index = 14; // sender's account index
const nft_id = 48;
const to_address = "0x09E45d6FcF322c4D93E6aFE7076601FF10BA942E";
const res = await sdk.withdrawNft(account_name, account_index, nft_id, to_address);

console.log("success: ", res);

Example result

success: true

    accountName := "bob"
    tol1Address := "0x< a l1 address you want to withdraw>"
    assetAmount := int64(100000)
    c, err := sdk.NewClient(accountName, seed)
    if err != nil { panic(err) }
   
    result, err := c.Withdraw(tol1Address,sdk.BNBAssetId, assetAmount)
    if err != nil { panic(err) }
    
    data, err := json.Marshal(result)
    fmt.Println("Withdraw:", string(data))
}
