Attention

Cross-chain bridges functionality is part of the proposed XLS-38d extension (Not Enabled) to the XRP Ledger protocol. There isn't an official amendment yet. Until there is an amendment, the details documented on these pages are subject to change frequently. [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.

XChainOwnedCreateAccountClaimID Fields

Field	JSON Type	Internal Type	Required?	Description
`Account`	`string`	`ACCOUNT`	Yes	The account that owns this object.
`LedgerIndex`	`string`	`HASH256`	Yes	The ledger index is a hash of a unique prefix for `XChainOwnedClaimID`s, the actual `XChainClaimID` value, and the fields in `XChainBridge`.
`XChainAccountCreateCount`	`number`	`UINT64`	Yes	An integer that determines the order that accounts created through cross-chain transfers must be performed. Smaller numbers must execute before larger numbers.
`XChainBridge`	`XChainBridge`	`XCHAIN_BRIDGE`	Yes	The door accounts and assets of the bridge this object correlates to.
`XChainCreateAccountAttestations`	`array`	`ARRAY`	Yes	Attestations collected from the witness servers. This includes the parameters needed to recreate the message that was signed, including the amount, destination, signature reward amount, and reward account for that signature. With the exception of the reward account, all signatures must sign the message created with common parameters.

XChainCreateAccountAttestations

Field	JSON Type	Internal Type	Required	Description
`XChainCreateAccountProofSig`	`array`	`OBJECT`	Yes	An attestation from one witness server.
`Amount`	`Currency Amount`	`AMOUNT`	Yes	The amount committed by the `XChainAccountCreateCommit` transaction on the source chain.
`AttestationRewardAccount`	`string`	`ACCOUNT`	Yes	The account that should receive this signer's share of the `SignatureReward`.
`AttestationSignerAccount`	`string`	`ACCOUNT`	Yes	The account on the door account's signer list that is signing the transaction.
`Destination`	`string`	`ACCOUNT`	Yes	The destination account for the funds on the destination chain.
`PublicKey`	`string`	`BLOB`	Yes	The public key used to verify the signature.
`WasLockingChainSend`	`number`	`UINT8`	Yes	A boolean representing the chain where the event occurred.

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

XCHAIN_BRIDGE is a new field type introduced by XLS-38d.

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.
