XChainCommit

(Requires the XChainBridge amendment )

The XChainCommit is the second step in a cross-chain transfer. It puts assets into trust on the locking chain so that they can be wrapped on the issuing chain, or burns wrapped assets on the issuing chain so that they can be returned on the locking chain.

XChainCommit Fields

Field	JSON Type	Internal Type	Required?	Description
`Amount`	Currency Amount	Amount	Yes	The asset to commit, and the quantity. This must match the door account's `LockingChainIssue` (if on the locking chain) or the door account's `IssuingChainIssue` (if on the issuing chain).
`OtherChainDestination`	String	Account	No	The destination account on the destination chain. If this is not specified, the account that submitted the `XChainCreateClaimID` transaction on the destination chain will need to submit a `XChainClaim` transaction to claim the funds.
`XChainBridge`	XChainBridge	XChain_Bridge	Yes	The bridge to use to transfer funds.
`XChainClaimID`	String	UInt64	Yes	The unique integer ID for a cross-chain transfer. This must be acquired on the destination chain (via a `XChainCreateClaimID` transaction) and checked from a validated ledger before submitting this transaction. If an incorrect sequence number is specified, the funds will be lost.

XChainBridge Fields

Field	JSON Type	Internal Type	Required?	Description
`IssuingChainDoor`	String	Account	Yes	The door account on the issuing chain. For an XRP-XRP bridge, this must be the genesis account (the account that is created when the network is first started, which contains all of the XRP).
`IssuingChainIssue`	Issue	Issue	Yes	The asset that is minted and burned on the issuing chain. For an IOU-IOU bridge, the issuer of the asset must be the door account on the issuing chain, to avoid supply issues.
`LockingChainDoor`	String	Account	Yes	The door account on the locking chain.
`LockingChainIssue`	Issue	Issue	Yes	The asset that is locked and unlocked on the locking chain.
