PaymentChannelClaim

Claim Amount from a payment channel, adjust the payment channel's expiration, or both. This transaction can be used differently depending on the transaction sender's role in the specified channel:

[Source]

Added by the [PayChan amendment][].

The source address of a channel can:

• Send Amount from the channel to the destination with or without a signed Claim.

• Set the channel to expire as soon as the channel's SettleDelay has passed.

• Clear a pending Expiration time.

• Close a channel immediately, with or without processing a claim first. The source address cannot close the channel immediately if the channel has Amount remaining.

The destination address of a channel can:

• Receive Amount from the channel using a signed Claim.

• Close the channel immediately after processing a Claim, refunding any unclaimed Amount to the channel's source.

Any address sending this transaction can:

• Cause a channel to be closed if its Expiration or CancelAfter time is older than the previous ledger's close time. Any validly-formed PaymentChannelClaim transaction has this effect regardless of the contents of the transaction.

Field	JSON Type	[Internal Type][]	Description
Channel	String	Hash256	The unique ID of the channel, as a 64-character hexadecimal string.
Balance	Currency Amount	Amount	(Optional) Total amount delivered by this channel after processing this claim. Required to deliver Amount. Must be more than the total amount delivered by the channel so far, but not greater than the Amount of the signed claim. Must be provided except when closing the channel.
Amount	Currency Amount	Amount	(Optional) The amount authorized by the Signature. This must match the amount in the signed message. This is the cumulative amount of Amount that can be dispensed by the channel, including XAH previously redeemed.
Signature	String	Blob	(Optional) The signature of this claim, as hexadecimal. The signed message contains the channel ID and the amount of the claim. Required unless the sender of the transaction is the source address of the channel.
PublicKey	String	Blob	(Optional) The public key used for the signature, as hexadecimal. This must match the PublicKey stored in the ledger for the channel. Required unless the sender of the transaction is the source address of the channel and the Signature field is omitted. (The transaction includes the public key so that rippled can check the validity of the signature before trying to apply the transaction to the ledger.)

If the payment channel was created before the fixPayChanRecipientOwnerDir amendment became enabled (on 2020-05-01), it is possible that the destination of the payment channel has been deleted and does not currently exist in the ledger. If the destination has been deleted, the source account cannot send XAH from the channel to the destination; instead, the transaction fails with tecNO_DST. (And, of course, the deleted account cannot send any transactions at all.) Other uses of this transaction type are unaffected when the destination account has been deleted, including adjusting the channel expiration, closing a channel with no Amount, or removing a channel that has passed its expiration time.

PaymentChannelClaim Flags

Transactions of the PaymentChannelClaim type support additional values in the Flags field, as follows:

Flag Name	Hex Value	Decimal Value	Description
tfRenew	0x00010000	65536	Clear the channel's Expiration time. (Expiration is different from the channel's immutable CancelAfter time.) Only the source address of the payment channel can use this flag.
tfClose	0x00020000	131072	Request to close the channel. Only the channel source and destination addresses can use this flag. This flag closes the channel immediately if it has no more Amount allocated to it after processing the current claim, or if the destination address uses it. If the source address uses this flag when the channel still holds an Amount, this schedules the channel to close after SettleDelay seconds have passed. (Specifically, this sets the Expiration of the channel to the close time of the previous ledger plus the channel's SettleDelay time, unless the channel already has an earlier Expiration time.) If the destination address uses this flag when the channel still holds an Amount, any Amount that remains after processing the claim is returned to the source address.
