getNFTTransfersByBlock

按块号或块哈希检索 NFT 传输。 返回一个 NFT 传输数组（异步）。

选项：

  • ​chain​（可选）：从中获取数据的区块链。 有效值列在支持的链上。 默认值 Eth。
  • ​block_number_or_hash​（必需）：块哈希或块号。

你可以使用​JS​、​React​、​curl​、​Unity​来实现

const options = { chain: "bsc", block_number_or_hash: "11284830" };

// get NFT transfers by block number or block hash
const NFTTransfers = await Moralis.Web3API.native.getNFTTransfersByBlock(
  options
);
import React from "react";
import { useMoralisWeb3Api } from "react-moralis";

const Web3Api = useMoralisWeb3Api();

const fetchNFTTransfersByBlock = async () => {
  // get NFT transfers by block number or block hash
  const options = { chain: "bsc", block_number_or_hash: "11284830" };

  const NFTTransfers = await Web3Api.native.getNFTTransfersByBlock(options);
  console.log(NFTTransfers);
};

getTransaction (新)

通过交易哈希获取交易。 返回一个事务对象（异步）。

选项：

  • ​chain​（可选）：从中获取数据的区块链。 有效值列在支持的链上。 默认值 Eth。

你可以使用​JS​、​React​、​curl​、​Unity​来实现

const options = {
  chain: "eth",
  transaction_hash:
