PaymentChannelClaim

Claim XRP 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:

The source address of a channel can:

Send XRP 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 XRP remaining.

The destination address of a channel can:

Receive XRP from the channel using a signed Claim.
Close the channel immediately after processing a Claim, refunding any unclaimed XRP 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.

PaymentChannelClaim Fields

In addition to the common fields, a PaymentChannelClaim transaction uses the following fields:

Field	JSON Type	Internal Type	Description
`Channel`	String	Hash256	The unique ID of the channel, as a 64-character hexadecimal string.
`Balance`	String	Amount	(Optional) Total amount of XRP, in drops, delivered by this channel after processing this claim. Required to deliver XRP. 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`	String	Amount	(Optional) The amount of XRP, in drops, authorized by the `Signature`. This must match the amount in the signed message. This is the cumulative amount of XRP that can be dispensed by the channel, including XRP 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 XRP 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 XRP, 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 XRP 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 XRP, 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 XRP, any XRP that remains after processing the claim is returned to the source address.
