8. Asset Deposits

• Users are able to deposit assets from L1 to L2 in Zecrey.

Initialize SDK

• You will need to initialize the SDK in order to use it.

Deposit NFT to L2

• Parameters needed:

  Parameter	Parameter usage and meaning	Requirement
  accountName	The account name used to initialize the client	✅
  seed	The user's L2 seed used to initialize the client	✅
  privateKey	Since this transaction involves L1, the private key of user's L1 account is needed to sign the transaction	✅
  nftL1Address	The corresponding L1 address of the NFT	✅
  nftIndex	The unique ID of NFT in L1	✅

📚SDK REFERENCE

• DepositNft

Golang

Example

• Deposit the NFT with nftIndex = 511

  • Initialize client

  • Deposit the NFT with nftIndex = 511

package main

import (
   "fmt"
   "github.com/Zecrey-Labs/zecrey-marketplace-go-sdk/sdk"
)


func main() {
    var nftIndex int64 = 511
    accountName := "Bob"
    seed := "17673b9a9fdec6dc90c7cc1eb1c939134dfb659d2f08edbe071e5c45f343d008"
    privateKey := "0xe94a8b4ddd33b2865asadfasda0c3e3276007ece8f114a47a4e9581ec3567"
    nftL1Address := common.HexToAddress("0x805e286D05388911s41a0E3c7b9713415607c72")
    c, err := NewClient(accountName, seed)
    if err != nil {
       t.Fatal(err)
    }
    depositNftTransaction, err := c.DepositNft(accountName, privateKey, nftL1Address, nftIndex)
    if err != nil {
       t.Fatal(err)
    }
    fmt.Println("tx hash: ",depositNftTransaction.Hash())
}

Example Result

tx hash: 0x832b75753c073b29a11431386f2faa744ced1c95603e8ea30e4aa5fd7ca3d14dgolang

Javascript

Example

Advance approval for NFT is require

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

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

const privateKey = "1bcb0ae8c17945acfaf9ea546c0b754a599fddf27425bac7e532590324137a7d"; // the private key of the L1 which is sending the transaction
const account = "Bob"; // the receiving L2 account in NFT deposit
const asset_contract = "0xD0b6eee86DFAE935E837EcC187A63D3882eDA022"; // the l1 contract address of NFT
const token_id = 4; // the ID of NFT in L1 contract

const res = await sdk.depositNft(privateKey, account, asset_contract, token_id);

console.log("tx hash: ", res);

Example Result

tx hash: 0x832b75753c073b29a11431386f2faa744ced1c95603e8ea30e4aa5fd7ca3d14d

  seed	The user's L2 seed used to initialize the client	✅
  privateKey	Since this transaction involves L1, the private key of user's L1 account is needed to sign the transaction	✅
  AssetId	Token ID	✅

• Token information

  Token	Token ID	Parameter
  BNB	0	sdk.BNBAssetId
  LEG	1	sdk.LEGAssetId
  REY	2	sdk.REYAssetId

📚SDK REFERENCE

• Deposit

Golang

Example

• Deposit 10000 BNB to L2

  • Initialize client

  • Deposit

    1. For BEP20 token, you need to import the token address

package main

import (
   "fmt"
   "github.com/Zecrey-Labs/zecrey-marketplace-go-sdk/sdk"
)


func main() {
    var nftId int64 = 6
    accountName := "Bob"
    seed := "17673b9a9fdec6dc90c7cc1eb1c939134dfb659d2f08edbe071e5c45f343d008"
    privateKey := "0xe94a8b4ddd33b2865asadfasda0c3e3276007ece8f114a47a4e9581ec3567"
    var assetAmount int64 = 10000
    var tokenAddress  = common.HexToAddress("")
    c, err := NewClient(accountName, seed)
    if err != nil { panic(err) }
    
    depositBnbTransaction, err := c.Deposit(accountName, privateKey, sdk.BNBAssetId, assetAmount, tokenAddress)
    if err != nil { panic(err) }
    
    fmt.Println("tx hash:",depositBnbTransaction.Hash())
}

Example result

tx hash: 0x0f20b7cf4f6526b7d67efba10c9e14b0c093eb9c50c7ebd8190413bc0b4c6dd6

Javascript

Example

1. Deposit BEP20 assets like REY and LEG (advance approval required for assets)

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

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

const privateKey = "1bcb0ae8c17945acfaf9ea546c0b754a599fddf27425bac7e532590324137a7d"; // the private key of the L1 which is sending the transaction
const account = "Bob"; // the L2 account that LEG is deposited to
const amount = "100000000000000"; // 0.0001 LEG
const asset_contract = "0x364Ed72f329f1BD56AE84b941D1c6E4E260cE152"; // the contract address of LEG

const res = await sdk.deposit(privateKey, account, amount, asset_contract);

console.log("tx hash: ", res);

1. Deposit BNB

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

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

const privateKey = "1bcb0ae8c17945acfaf9ea546c0b754a599fddf27425bac7e532590324137a7d"; // the private key of the L1 which is sending the transaction
const account = "Bob"; // the L2 account that LEG is deposited to
const amount = "100000000000000"; // 0.0001 BNB 

const res = await sdk.deposit(privateKey, account, amount);

console.log("tx hash: ", res);

Example Result
