XChainOwnedCreateAccountClaimID

(Requires the XChainBridge amendment )

[Source]

The XChainOwnedCreateAccountClaimID ledger object is used to collect attestations for creating an account via a cross-chain transfer.

It is created when an XChainAddAccountCreateAttestation transaction adds a signature attesting to a XChainAccountCreateCommit transaction and the XChainAccountCreateCount is greater than or equal to the current XChainAccountClaimCount on the Bridge ledger object.

The ledger object is destroyed when all the attestations have been received and the funds have transferred to the new account.
