This transaction can only be used for XRP-XRP bridges.

The XChainAccountCreateCommit transaction creates a new account for a witness server to submit transactions on an issuing chain.

Warning: This transaction should only be executed if the witness attestations will be reliably delivered to the destination chain. If the signatures aren't delivered, then account creation will be blocked until attestations are received. This can be used maliciously; to disable this transaction on XRP-XRP bridges, the bridge's MinAccountCreateAmount shouldn't be present.

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.

XCHAIN_BRIDGE Field Type

Type Name	Type Code	Bit Length	Length-prefixed?	Description
`XCHAIN_BRIDGE`	25	Variable	No	A bridge between two blockchains, identified by the door accounts and issued assets on the locking chain and issuing chain. `XCHAIN_BRIDGE` is serialized in this order: locking chain door, locking chain issue, issuing chain door, issuing chain issue.
