web3.js - Ethereum のアドレスをチェックサム付きアドレスに変換する

サンプルコード

code:example.js

let lowerCaseAddress = "0x0089d53f703f7e0843953d48133f74ce247184c2"

let upperCaseAddress = "0x0089D53F703F7E0843953D48133F74CE247184C2"

console.log(Web3.utils.toChecksumAddress(lowerCaseAddress))

// => 0x0089d53F703f7E0843953D48133f74cE247184c2

console.log(Web3.utils.toChecksumAddress(upperCaseAddress))

// => 0x0089d53F703f7E0843953D48133f74cE247184c2

動作デモ

code:demo.js

$(document.body).append('<h1>Convert Ethereum address to Checksum address</h1>')

$(document.body).append('<p>address: <input type="text" size="70" id="input">')

$(document.body).append('<p>result: <input type="text" size="70" id="result" readonly></p>')

$('#input').on('input', function(event) {

let address = $('#input').val()

if (address.length >= 40) {

let result = Web3.utils.toChecksumAddress(address)

$('#result').val(result)

}

})
