# XRP

## Code

* `XrpBridge.sol`
* `XrpBridge.impl.sol`

## Address

* Xrp Bridge Symbol : `XRP`
* Xrp Bridge Contract Address : `0x4E6C37162021FdA832fB95aFF42Af92c2e8B6257`

## Events

### XrpTransactionSuggested

```bash
event XrpTransactionSuggested(bytes32 govId, uint swapIndex, uint suggestIndex);Event occurs when Bridge Operator proposes Raw Transaction Data of Terra Chain,
```

* `bytes32 govId` : Unique Identifier of Governance
* `uint swapIndex` : Swap Data Index
* `uint suggestIndex` : Suggestion Data Index

### XrpTransactionSelected

```bash
event XrpTransactionSelected(bytes32 govId, uint selectionIndex);
```

Event will occur upon completion of agreement on the raw transaction data of XRP Chain by a Bridge Validator

* `bytes32 govId` : Unique Identifier of Governance
* `uint selectionIndex` : Selection Data Index

### XrpTransactionValidated

```bash
event XrpTransactionValidated(bytes32 govId, uint selectionIndex, string fromChain, bytes32[] bytes32s, uint[] uints);
```

Event occurs when a Bridge Validator submits a Signature for agreed Raw Transaction Data

* `bytes32 govId` : Unique Identifier of Governance
* `uint selectionIndex` : Selection Data Index
* `string fromChain` : Chain Symbol requesting bridging
* `bytes32[] bytes32s` : Bytes32 Data Array corresponding to Selection Data
* `uint[] uints` : Bytes32 Data Array corresponding to Selection Data
