HashTimeLockContract class

Hash Time Locked Contract allows a user to receive the Algo prior to a deadline (in terms of a round) by proving knowledge of a special value or to forfeit the ability to claim, returning it to the payer.

This contract is usually used to perform cross-chained atomic swaps.

More formally, algos can be transfered under only two circumstances:

1. To receiver if hash_function(arg_0) = hash_value
2. To owner if txn.FirstValid > expiry_round

Static Methods

create({required Address owner, required Address receiver, required HashFunction hashFunction, required String hashImage, required int expiryRound, required int maxFee}) → ContractTemplate

Create a new Hash Time Locked Contract. This allows a user to receive Algo prior to a deadline by proving knowledge of a special value or to forfeit the ability to claim, returning it to the payer.

getTransaction({required ContractTemplate contract, required String preImage, required int firstValid, required int lastValid, required String genesisHash, required int feePerByte}) → Future<SignedTransaction>

Read and verify the contract, and return the signed transaction
