PantosToken ABI

The Pantos Token ABI is a JSON representation of the PantosToken smart contract's interface, containing the functions and events necessary for interacting with cross-chain tokens.

The ABI acts as an interface between the contract's bytecode and the outside world. Here's a breakdown of the important elements in the Pantos Token ABI.

Functions

pantosTransfer

Called by the Pantos Forwarder to transfer tokens on a blockchain.

The function is only callable by a trusted Pantos Forwarder contract and thefore can't be invoked by a user. The function is used to transfer tokens on a blockchain between the sender and recipient. Revert if anything prevents the transfer from happening.

function pantosTransfer(address sender, address recipient, uint256 amount)
    external;

Parameters

Name	Type	Description
sender	address	The address of the sender of the tokens.
recipient	address	The address of the recipient of the tokens.
amount	uint256	The amount of tokens to mint.

pantosTransferFrom

Called by the Pantos Forwarder to debit tokens on the source blockchain during a cross-chain transfer.

The function is only callable by a trusted Pantos Forwarder contract and thefore can't be invoked by a user. The function is used to burn tokens on the source blockchain to initiate a cross-chain transfer. Revert if anything prevents the transfer from happening.

function pantosTransferFrom(address sender, uint256 amount) external;

Parameters

Name	Type	Description
sender	address	The address of the sender of the tokens.
amount	uint256	The amount of tokens to send/burn.

pantosTransferTo

Called by the Pantos Forwarder to mint tokens on the destination blockchain during a cross-chain transfer.

The function is only callable by a trusted Pantos Forwarder contract and thefore can't be invoked by a user. The function is used to mint tokens on the destination blockchain to finish a cross-chain transfer. Revert if anything prevents the transfer from happening.

function pantosTransferTo(address recipient, uint256 amount) external;

Parameters

Name	Type	Description
recipient	address	The address of the recipient of the tokens.
amount	uint256	The amount of tokens to mint.

getPantosForwarder

Returns the address of the Pantos Forwarder contract.

function getPantosForwarder() external view returns (address);

Returns

Name	Type	Description
<none>	address	Address of the Pantos Forwarder.

totalSupply

Returns the value of tokens in existence.

function totalSupply() external view returns (uint256);

balanceOf

Returns the value of tokens owned by account.

function balanceOf(address account) external view returns (uint256);

transfer

Moves a value amount of tokens from the caller's account to to. Returns a boolean value indicating whether the operation succeeded. Emits a Transfer event.

function transfer(address to, uint256 value) external returns (bool);

allowance

Returns the remaining number of tokens that spender will be allowed to spend on behalf of owner through transferFrom. This is zero by default. This value changes when {approve} or {transferFrom} are called.

function allowance(address owner, address spender) external view returns (uint256);

approve

Sets a value amount of tokens as the allowance of spender over the caller's tokens. Returns a boolean value indicating whether the operation succeeded. IMPORTANT: Beware that changing an allowance with this method brings the risk that someone may use both the old and the new allowance by unfortunate transaction ordering. One possible solution to mitigate this race condition is to first reduce the spender's allowance to 0 and set the desired value afterwards: https://github.com/ethereum/EIPs/issues/20#issuecomment-263524729 Emits an Approval event.

function approve(address spender, uint256 value) external returns (bool);

transferFrom

Moves a value amount of tokens from from to to using the allowance mechanism. value is then deducted from the caller's allowance. Returns a boolean value indicating whether the operation succeeded. Emits a Transfer event.

function transferFrom(address from, address to, uint256 value) external returns (bool);

decimals

function decimals() external view returns (uint8);

Returns

Name	Type	Description
<none>	uint8	The token decimals.

symbol

function symbol() external view returns (string memory);

Returns

Name	Type	Description
<none>	string	The token symbol.

name

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

Returns

Name	Type	Description
<none>	string	The token name.

getOwner

function getOwner() external view returns (address);

Returns

Name	Type	Description
<none>	address	The token owner.

supportsInterface

Returns true if this contract implements the interface defined by interfaceId. See the corresponding https://eips.ethereum.org/EIPS/eip-165#how-interfaces-are-identified[EIP section] to learn more about how these ids are created. This function call must use less than 30 000 gas.

function supportsInterface(bytes4 interfaceId) external view returns (bool);

Events

PantosForwarderSet

event PantosForwarderSet(address pantosForwarder);

PantosForwarderUnset

event PantosForwarderUnset();

Transfer

Emitted when value tokens are moved from one account (from) to another (to). Note that value may be zero.

event Transfer(address indexed from, address indexed to, uint256 value);

Approval

Emitted when the allowance of a spender for an owner is set by a call to approve. value is the new allowance.

event Approval(address indexed owner, address indexed spender, uint256 value);
