Bank

Bank Precompiles contract is a gate-way that allowed Solidity contracts can interact with Cosmos SDK Bank module. This is convenient for developers as they don’t need to know the implementation details behind the x/bank module in the Cosmos SDK. Instead, they can interact with bank functions using the Ethereum interface they are familiar with.

Solidity Interfaces

The Bank solidity interface includes the following transactions

• send

Send defined a method that perform sending logic to a specific address

function send(
        address toAddress,
        string memory denom,
        uint256 amount
    ) external returns (bool success);

• burn

Burn defined a method that perform burning amount of token from a specific address

function burn(
        address account,
        string memory denom,
        uint256 amount
    ) external returns (bool success);

• balance

Balance defined a query method that get a user balance of a specific denomination

function balance(
        address acc,
        string memory denom
    ) external view returns (uint256 amount);

• name

Get the Name that defined in Token Metadata

function name(
        string memory denom
    ) external view returns (string memory response);

• symbol
