# Rune/BRC20 swap
Welcome to the **Rune/BRC20 SWAP**, a decentralized application (dApp) built in the Bitcoin space. This can create **Rune/Brc20-BTC** pair pools and start swapping. When someone swaps, this can set the **locking satus** to true to prevent UTXO conflicts, meaning no one else can access the pool in progress.
## Key Features:
- **Pool Locking:** When a user performs a swap, the pool lock status is updated to prevent concurrent operations.
- **UTXO Management:** Ensures that used transaction outputs (UTXOs) are stored and tracked to avoid confusion when fetching UTXOs for transactions.
- **BRC20 Inscription Validation:** Before transferring BRC20 tokens, it checks if the address holds transferable inscription data.
## Example Code Snippets
### Pool Locking:
When a user performs a swap, the pool lock status is updated to prevent concurrent swaps.
```javascript
// Update pool lock status as false if pool and lockedByAddress match
export const updatePoolLockStatus = async (
poolAddress: string,
tokenType: string,
userAddress: string
) => {
// Implementation as described above
};
```
### UTXO Management:
To avoid using already claimed UTXOs, we store used transaction information and filter out used UTXOs when fetching them:
```javascript
// Model to store used transaction information
const UsedTxInfo = new mongoose.Schema({
txid: { type: String, required: true },
confirmedTx: { type: String, required: true },
createdAt: { type: Date, default: new Date(new Date().toUTCString()) },
});
const UsedTxInfoModal = mongoose.model("UsedTxInfo", UsedTxInfo);
export default UsedTxInfoModal;
```
### BRC20 Inscription Validation:
For BRC20 token transfers, it checks if the user's address has the required transferable inscription data:
```javascript
export const getBrc20TransferableInscriptionUtxoByAddress = async (address: string, ticker: string) => {
const url = `${OPENAPI_UNISAT_URL}/v1/indexer/address/${address}/brc20/${ticker}/transferable-inscriptions`;
const config = {
headers: {
Authorization: `Bearer ${OPENAPI_UNISAT_TOKEN}`,
},
};
const inscriptionList = (await axios.get(url, config)).data.data.detail;
return inscriptionList;
};
```
### Swap Hisotry Model:
```javascript
const SwapHistory = new mongoose.Schema({
poolAddress: { type: String, required: true },
userAddress: { type: String, required: true },
tokenType: { type: String, required: true },
txId: { type: String, required: true },
tokenAmount: { type: Number, required: true },
btcAmount: { type: Number, required: true },
swapType: { type: Number, required: true },
createdAt: { type: Date, default: new Date(new Date().toUTCString()) },
});
const SwapHistoryModal = mongoose.model("SwapHistory", SwapHistory);
export default SwapHistoryModal;
```
