getFundingAddress :: ChannelParameters -> Address

Derive a Bitcoin address, for funding a payment channel, from ChannelParameters. The transaction which pays to this address is the channel funding transaction, and information about this transaction is contained in FundingTxInfo.

getRedeemScript :: ChannelParameters -> Script

setSenderChangeAddress :: PaymentChannel a => a -> Address -> a

Set new value sender change address

serialize :: Serialize a => a -> ByteString

deserEither :: forall a. (Typeable a, Serialize a) => ByteString -> Either String a

data BitcoinLockTime

Data type representing a Bitcoin LockTime, which specifies a point in time. Derive a BitcoinLockTime from a UTCTime using fromDate.

parseBitcoinLocktime :: Word32 -> BitcoinLockTime

Convert from Bitcoin format (Word32)

toWord32 :: BitcoinLockTime -> Word32

Convert to Bitcoin format (uint32 UNIX timestamp)

fromDate :: UTCTime -> BitcoinLockTime

parseJSONInt :: Scientific -> Parser Integer

pGetSig :: Payment -> Signature

fpGetSig :: FullPayment -> Signature

unsafeUpdateRecvState :: ReceiverPaymentChannelI a -> Payment -> ReceiverPaymentChannelI a

Update internal state without signature verification. Useful for database-type services where a logic layer has already verified the signature, and it just needs to be stored.
