XChainCreateBridge
Create a new cross-chain bridge on the chain that the transaction is submitted on, providing information about door accounts and assets for the bridge.
The transaction must be submitted first by the locking chain door account. To set up a valid bridge, door accounts on both chains must submit this transaction, in addition to setting up witness servers.
The complete production-grade setup would also include a SignerListSet transaction on the two door accounts for the witnesses’ signing keys, as well as disabling the door accounts’ master key. This ensures that the witness servers are truly in control of the funds.

| Field | JSON Type | Internal Type | Required? | Description |
|---|---|---|---|---|
MinAccountCreateAmount | Currency Amount | Amount | No | The minimum amount, in XRP, required for a XChainAccountCreateCommit transaction. If this isn't present, the XChainAccountCreateCommit transaction will fail. This field can only be present on XRP-XRP bridges. |

IssuingChainDoor | String | AccountID | 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 | AccountID | Yes | The door account on the locking chain. |
LockingChainIssue | Issue | Issue | Yes | The asset that is locked and unlocked on the locking chain. |
