Erc20 abi

The Contract Address 0xaa628593c3e585530571716f84798368fecf5640 page allows users to view the source code, transactions, balances, and analytics for the contract.... "/>.

ERC20 Implementation of the IERC20 interface. This implementation is agnostic to the way tokens are created. This means that a supply mechanism has to be added in a derived contract using _mint . For a generic mechanism see ERC20Mintable. For a detailed writeup see our guide How to implement supply mechanisms. */ function toEthSignedMessageHash(bytes32 hash) internal pure returns (bytes32) { // 32 is the length in bytes of hash, // enforced by the type signature above return keccak256(abi.encodePacked("\x19Ethereum Signed Message:\n32", hash)); } } /** * @dev Interface of the ERC20 standard as defined in the EIP.

Then compile the smart contract to the JSON ABI, and create a Go token package out of the ABI using abigen. solc --abi erc20.sol abigen --abi=erc20_sol_ERC20.abi --pkg=token --out=erc20.go. Assuming we already have Ethereum client set up as usual, we can now import the new token package into our application and instantiate it.

First create the ERC-20 smart contract interface for event logs as erc20.sol: pragma solidity ^0.4.24; contract ERC20 { event Transfer(address indexed from, address indexed to, uint tokens); event Approval(address indexed tokenOwner, address indexed spender, uint tokens); } Then use abigen to create the Go exchange package given the abi:. This diagram illustrate the steps of how the process works. First an ERC20 token is published to the ethereum network; The token is assigned a contract address and has an ABI.

The function arguments are then ABI encoded into a single byte array and concatenated with the function selector. ABI encoding simple types means left padding each argument to 32 bytes. This data is then sent to the address of the contract, which is able to decode the arguments and execute the code. Fallback function.
