Provides developers frquently-used blockchain tools in online.

I opened website (https://blockchains.tools) which provides developers blockchain-related tools and functions, for example, keccak256 hash or private key to public address for Ethereum.

Currently supporting tools

The website currently supports following features:

  • Byte array to hex (2 way convertible)
  • BigNumber to hex (2 way convertible)
  • Base58 encoder / decoder
  • ED25519
  • Keccak256
  • UTF8
  • (ETH) Get a contract address from sender address & nonce
  • (ETH) Private key to Public key and address
  • (ETH) Raw transaction encoder / decoder
  • (ETH) Ethereum unit(wei) converter

I’m wondering there is any frequently-used function which I am missing.

I would love for you to recommend some additional tools / functions to be added on this site. Any recommendation would be good.

⚠️ Warning

All functions listed on this site doesn’t use external network API. They even could be used without a network connection. Even so, I recommend not to type your private information, for example, your real private key. You should always be careful of your browser is safe from being hacked. (Some chrome extension can peek what you’re typing. 👀)
