eth和tron地址互转工具类(java)

eth和tron地址互转工具类(java)

1、依赖导入

<dependency>
	<groupId>org.web3j</groupId>
    <artifactId>core</artifactId>
    <version>4.9.4</version>
</dependency>
<dependency>
	<groupId>org.bitcoinj</groupId>
    <artifactId>bitcoinj-core</artifactId>
    <version>0.16.2</version>
</dependency>

2、代码实现

package org.example.test;

import org.bitcoinj.core.Base58;
import org.bouncycastle.util.encoders.Hex;
import org.web3j.crypto.Keys;

import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;

public class AddressChangeUtils {

    public static String ethToTron(String ethAddress) {
        if (ethAddress.startsWith("0x")) {
            ethAddress = ethAddress.substring(2);
        }
        ethAddress = "41" + ethAddress;
        byte[] byte1 = Hex.decode(ethAddress);
        byte[] byte2 = sha256(byte1);
        byte[] byte3 = sha256(byte2);
        byte[] result = new byte[byte1.length + 4];
        System.arraycopy(byte1, 0, result, 0, byte1.length);
        System.arraycopy(byte3, 0, result, byte1.length, 4);
        return Base58.encode(result);
    }

    public static String tronToEth(String tronAddress) {
        String s = "0x" + Hex.toHexString(Base58.decodeChecked(tronAddress)).substring(2);
        return Keys.toChecksumAddress(s);
    }

    private static byte[] sha256(byte[] data) {
        try {
            MessageDigest digest = MessageDigest.getInstance("SHA-256");
            return digest.digest(data);
        } catch (NoSuchAlgorithmException e) {
            throw new RuntimeException("SHA-256 algorithm not found", e);
        }
    }

}
