CrossChain Precompiled

Address: 0x0000000000000000000000000000000000001004

ABI: ICrossChain

Overview: Use cross-chain precompiled contract to call some functions of the cross-chain module, such as: crossChain, etc.

Method

crossChain (Deprecated)

send token from Pundi AIFX to other chain, like ethereum, pundix, etc.

if token is erc20, must be approved before calling this method

// Deprecated: please use `IBridgeCall.bridgeCall`
function crossChain(
    address _token,
    string memory _receipt,
    uint256 _amount,
    uint256 _fee,
    bytes32 _target,
    string memory _memo
) external payable returns (result bool);

• _token: the token address on the Pundi AIFX(Tokens)

  • if token is origin token, _token address is 0x0000000000000000000000000000000000000000

• _receipt: the receipt address on the target chain

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

• _fee: the fee of the token to be cross chain

  • if cross chain to cosmos chain, _fee is 0

• _target: the target of the token on the target chain(more detail see Target

  • _target represents cross chain destination, such as chain ethereum, pundix

  • destination ethereum: _target is eth

  • destination other cosmos chain(example Pundix): _target 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)

• _memo: the memo of cross chain

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

crossChain event

event CrossChain(
    address indexed sender,
    address indexed token,
    string denom,
    string receipt,
    uint256 amount,
    uint256 fee,
    bytes32 target,
    string memo
);

• sender: the sender address

• token: the erc20 token address on the Pundi AIFX

• denom: the cross chain token denom

• receipt: the receipt address on the target chain

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

• fee: the fee of the token to be cross chain

• target: the target of cross chain

• memo: the memo of cross chain
