​
Application Binary Interface (ABI)

The ABI defines how to interact with the mantraUSD smart contract. This page provides the contract interface and function signatures.

​
Contract Address

Address: 0xd2b95283011E47257917770D28Bb3EE44c849f6F View on Blockscout

​
Standard ERC-20 Functions

​
balanceOf

Get the token balance of an address. 
function balanceOf(address account) external view returns (uint256)
Parameters:
  • account (address): The address to query
Returns:
  • uint256: The token balance

​
totalSupply

Get the total supply of mantraUSD tokens. 
function totalSupply() external view returns (uint256)
Returns:
  • uint256: The total token supply

​
transfer

Transfer tokens to another address. 
function transfer(address to, uint256 amount) external returns (bool)
Parameters:
  • to (address): The recipient address
  • amount (uint256): The amount to transfer
Returns:
  • bool: Success status

​
approve

Approve another address to spend tokens on your behalf. 
function approve(address spender, uint256 amount) external returns (bool)
Parameters:
  • spender (address): The address authorized to spend
  • amount (uint256): The maximum amount that can be spent
Returns:
  • bool: Success status

​
transferFrom

Transfer tokens from one address to another (requires approval). 
function transferFrom(address from, address to, uint256 amount) external returns (bool)
Parameters:
  • from (address): The sender address
  • to (address): The recipient address
  • amount (uint256): The amount to transfer
Returns:
  • bool: Success status

​
allowance

Check the amount of tokens a spender is allowed to spend. 
function allowance(address owner, address spender) external view returns (uint256)
Parameters:
  • owner (address): The token owner address
  • spender (address): The spender address
Returns:
  • uint256: The approved amount

​
Events

​
Transfer

Emitted when tokens are transferred. 
event Transfer(address indexed from, address indexed to, uint256 value)

​
Approval

Emitted when an approval is set. 
event Approval(address indexed owner, address indexed spender, uint256 value)

​
Custom Functions

The exact custom functions depend on the contract implementation. Check the verified contract source code on Blockscout for the complete ABI, or refer to the contract documentation.

​
Getting the Full ABI

To get the complete ABI:
  1. Visit the contract on Blockscout
  2. Navigate to the “Contract” tab
  3. Copy the ABI from the verified contract source

Usage Examples

​
Check Balance

const contract = new ethers.Contract(
  '0xd2b95283011E47257917770D28Bb3EE44c849f6F',
  abi,
  provider
);

const balance = await contract.balanceOf(userAddress);
console.log('Balance:', ethers.utils.formatEther(balance));

​
Transfer Tokens

const signer = provider.getSigner();
const contract = new ethers.Contract(
  '0xd2b95283011E47257917770D28Bb3EE44c849f6F',
  abi,
  signer
);

const tx = await contract.transfer(recipientAddress, amount);
await tx.wait();
