nft-cross-chain-protocol
NFT cross chain protocol on jingtum chain
ETH -> SWTC
NFT 从以太坊跨链到井通
交易分两步:
- 用户在以太坊调用 nft dao 合约 deposit,将 721 转账给以太坊合约。
- 用户调用 submitDepositOrder 在井通链上转账 1 swt 到井通 nft 银关地址, 附带相关跨链信息。
import { NFTDao } from "@jccdex/ethereum-contract";
import NFTTransaction from "@jccdex/nft-cross-chain-protocol";
const options = {
account: ethereum.selectedAddress,
chainId: "以太坊chain id",
web3: this.web3,
nftDaoContract: "以太坊nft dao合约地址",
multicallAddress: "以太坊multicall合约地址"
};
const nftDao = new NFTDao(options);
const nft = "NFT合约地址";
const id = "NFT id";
const jingtum = "井通地址";
const fee = "手续费,默认为0";
// 充币,从以太坊到井通
// 充币前需检查nft是否授权给nft dao合约,调用erc-721.ts isApprovedForAll方法
// 如果未授权,调用setApprovalForAll方法
const result = await nftDao.deposit(nft, id, jingtum, fee);
const jingtumNft = "井通NFT银关地址";
// 井通rpc节点数组
const nodes = [""];
const nftTransaction = new NFTTransaction(jingtumNft, nodes);
const depositData = {
from: "用户以太坊地址",
address: "用户井通地址",
secret: "用户井通密钥",
nft: "以太坊nft合约地址",
id: "以太坊nft id",
depositHash: "上述deposit交易hash"
};
const hash = await nftTransaction.submitDepositOrder(depositData);
SWTC -> ETH
NFT 从井通跨链到以太坊
交易分两步:
- 用户调用 transfer721 在井通链上将 721 转账给井通 721 银关地址。
- 用户调用 submitWithdrawOrder 支付 0.0075 jeth 作为手续费到井通 721 银关地址,附带相关跨链信息。
import NFTTransaction from "@jccdex/nft-cross-chain-protocol";
const jingtumNft = "井通NFT银关地址";
// 井通rpc节点数组
const nodes = [""];
// 测试链手续费
const fee = {
currency: "JETH",
value: "0.0075",
issuer: "jGa9J9TkqtBcUoHe2zqhVFFbgUVED6o9or"
};
// 主链fee可不设
// 主链默认手续费
// {
// currency: "JETH",
// value: "0.0075",
// issuer: "jGa9J9TkqtBcUoHe2zqhVFFbgUVED6o9or"
// }
const nftTransaction = new NFTTransaction(jingtumNft, nodes, fee);
const address = "";
const secret = "";
const id = "";
const hash721 = await nftTransaction.transfer721(address, secret, id);
const withdrawData = {
address: "用户井通地址",
secret: "用户井通密钥",
to: "用户以太坊地址",
publisher: "井通nft发行方地址",
tokenId: "井通nft token id",
fundCode: "井通nft fund code",
depositHash: "上述transfer721 hash"
};
const hash = await nftTransaction.submitWithdrawOrder(withdrawData);
