All ERC 20 Tokens

“Ethereum Request for Comment” else known as ERC-20 tokens technically refer to the standard imposed on projects that are looking to be part of the Ethereum blockchain through smart contracts. In simple words, the ERC-20 empowers a consistent set of rules overseeing how tokens are executed on the network.

Crypto APIs supports ALL ERC20 tokens including Tether(ERC20)/USDT(ERC20) that is used by many exchanges. You can use Crypto APIs’ support for all ERC20 tokens to:

Create ERC20 addresses

Get Webhook notifications whenever there is movement on generated by Crypto APIs addresses or your own addresses.

Automatically forward tokens to other wallets by choosing what percentage you would like to auto-forward.

With Crypto APIs ERC20 token support you can do the following actions:

  • totalSupply – total number of ERC-20 tokens created
  • balanceOf – tokens of one account
  • transfer – the token number that can be transferred
  • transferFrom – where the tokens are coming from
  • approve – validates the integrity
  • allowance – validates the user has sufficient tokens

Crypto APIs supports all ERC20(ERC-20) and ERC721(ERC-721) token.
