PaymentChannelFund

Add additional XRP to an open payment channel, and optionally update the expiration time of the channel. Only the source address of the channel can use this transaction.

Example PaymentChannelFund:

{
    "Account": "rf1BiGeXwwQoi8Z2ueFYTEXSwuJYfV2Jpn",
    "TransactionType": "PaymentChannelFund",
    "Channel": "C1AE6DDDEEC05CF2978C0BAD6FE302948E9533691DC749DCDD3B9E5992CA6198",
    "Amount": "200000",
    "Expiration": 543171558
}

PaymentChannelFund Fields

In addition to the common fields, PaymentChannelFund transactions use the following fields:

Field	JSON Type	Internal Type	Description
`Channel`	String	Hash256	The unique ID of the channel to fund, as a 64-character hexadecimal string.
`Amount`	String	Amount	Amount of XRP, in drops to add to the channel. Must be a positive amount of XRP.
`Expiration`	Number	UInt32	(Optional) New `Expiration` time to set for the channel, in seconds since the Ripple Epoch. This must be later than either the current time plus the `SettleDelay` of the channel, or the existing `Expiration` of the channel. After the `Expiration` time, any transaction that would access the channel closes the channel without taking its normal action. Any unspent XRP is returned to the source address when the channel closes. (`Expiration` is separate from the channel's immutable `CancelAfter` time.) For more information, see the PayChannel ledger object type.

Error Cases

Besides errors that can occur for all transactions, PaymentChannelFund transactions can result in the following transaction result codes:

Error Code	Description
`tecINSUFFICIENT_RESERVE`	The sending account has less XRP than the reserve requirement.
`tecNO_DST`	The destination account of the channel has been deleted. This is only possible if the payment channel was created before the fixPayChanRecipientOwnerDir amendment became enabled (on 2020-05-01).
`tecNO_ENTRY`	The Payment Channel identified by the `Channel` field does not exist.
`tecNO_PERMISSION`	The sender of the transaction is not the source address for the channel.
`tecUNFUNDED`	The sending account does not have enough XRP to fund the channel with the requested amount and still meet the reserve requirement.
`temBAD_AMOUNT`	The `Amount` field of the transaction is invalid. The amount must be XRP and it cannot be zero or negative.
`temBAD_EXPIRATION`	The `Expiration` field is invalid.
