sendToFx

sendToFx cross chain means that the contract deployed on other chains communicates with Pundi AIFX through cross chain bridge to realize cross chain with Pundi AIFX.

supported external chains:

• Ethereum

• Binance Smart Chain

• Polygon

• Tron

• Avalanche

• Optimism

• Arbitrum

Method

sendToFx

send token from external chain to Pundi AIFX

must be approved before calling this method

function sendToFx(address _tokenContract, bytes32 _destination, bytes32 _targetIBC, uint256 _amount) external;

• _tokenContract: the contract address of the token on the external chain

• _destination: the destination address on the Pundi AIFX chain or other cosmos chain

• _targetIBC: the target of the token on the Pundi AIFX chain(more details see Target)

  • _targetIBC represents cross chain destination, such as Pundi AIFX, Pundix, Marginx

  • destination Pundi AIFX: _targetIBC is empty

  • destination erc20 token: _targetIBC is erc20

  • destination other cosmos chain(example Pundix): _targetIBC is ibc/{id}/{prefix}.

    • id is the channel id of the target chain on Pundi AIFX(examples: Pundix: 0)

    • prefix is the address prefix of the target chain(examples: Pundix: px)

• _amount: the amount of the token to be cross chain

_destination convert address to bytes, if less than 32, fill in 0 in front, until 32 bytes

_targetIBC convert string to bytes, if less than 32, fill in 0 in behind, until 32 bytes

getBridgeTokenList

get cross chain token list

function getBridgeTokenList() external view returns (BridgeToken[] memory);

BridgeToken struct

struct BridgeToken {
    address addr;
    string name;
    string symbol;
    uint8 decimals;
}

checkAssetStatus

check if the token is supported cross chain

function checkAssetStatus(address _tokenAddr) external view returns (bool status);

• _tokenAddr: the contract address of the token on the external chain

• status: true means good condition
