before_init_transfer

FT4 Library / FT4 Library / lib.ft4.core.crosschain

@extendable function before_init_transfer(sender: account, recipient_id: byte_array, asset: asset, amount: big_integer, hops: list<byte_array>, deadline: integer)

source

Extendable function that allows the developer to add more functionality to the init_transfer function, before the transfer is initialised.

This allows, for example, to check that any condition is met before the transfer is initialised.

If this function throws, the transfer will not be initialized.

Throws when any extension of this function throws.

Parameters

sender — the account that is transferring the tokens
recipient_id — the ID of the recipient account on the end chain
asset — the asset to be transferred
amount — the amount to be transferred
hops — the IDs of the chains this transfer will go through
deadline — a timestamp after which the transfer can only be recalled
