Functions

isSubmissionUsed

  function isSubmissionUsed(
            bytes32 submissionId
  ) external returns (bool)

Returns whether the transfer with the submissionId was claimed. submissionId is generated in getSubmissionIdFrom

  function getNativeInfo(
            address token
  ) external returns (uint256 nativeChainId, bytes nativeAddress)

Returns native token info by wrapped token address

send

  function send(
            address _tokenAddress,
            uint256 _amount,

  ) external

This method is used for the transfer of assets from the native chain. It locks an asset in the smart contract in the native chain and enables minting of deAsset on the secondary chain.

Parameters:

Name	Type	Description
_tokenAddress	address	Asset identifier.
_amount	uint256	Amount to be transferred (note: the fee can be applied).
_chainIdTo	uint256	Chain id of the target chain.
_receiver	bytes	Receiver address.
_permit	bytes	deadline + signature for approving the spender by signature.
_useAssetFee	bool	use assets fee for pay protocol fix (work only for specials token)
_referralCode	uint32	Referral code
_autoParams	bytes	Auto params for external call in target network

claim

  function claim(
            bytes32 _debridgeId,

            address _receiver,
            uint256 _nonce,
            bytes _signatures,
            bytes _autoParams
  ) external

Is used for transfers into the native chain to unlock the designated amount of asset from collateral and transfer it to the receiver.

Parameters:

Name	Type	Description
