# Bitcoin fractal-brc20-launchpad
The BRC-20 Token Launchpad on the Fractal Bitcoin Network is tailored to showcase newly deployed tokens and their minting progress. It enables users to independently deploy, mint, and transfer these tokens.
## Features
- **Token Deployment:** Seamlessly deploy new BRC20 tokens on the network.
- **Minting Progress Tracking:** Monitor the status of token minting in real-time.
- **Token Transfers:** Safely transfer BRC20 tokens to other addresses.
- **Scalability:** Engineered with Node.js and TypeScript to support efficient scaling.
- **Comprehensive API:** Offers a robust API for managing and interacting with BRC20 tokens.
## Github Reference Repository
```bash
git clone https://github.com/bitman310/fractal-brc20-launchpad.git
cd fractal-brc20-launchpad
```

### API Endpoints
- **Deploy Token**: `POST /api/tokens/deploy`
- **Mint Token**: `POST /api/tokens/mint`
- **Transfer Token**: `POST /api/tokens/transfer`
### BRC20 Token Codebase Part
- **BRC20 Send Function**
```typescript
/**
* reveal a brc20 txid
*
* @param {Signer} keypair - The number of keypair
* @param {string} p - The mark of inscription, like ord
* @param {string} data - The data inside an brc20
* @param {string} txid - The txid used to reveal
* @param {string} network - The network used for taproot address
* @returns {{ p2tr, redeem }} - return an taproot address and its reedem script
*/
export async function brc20_send(keypair: Signer, p: string, data: string, txid: string, network: string) {
const ins_script = [
toXOnly(keypair.publicKey),
opcodes.OP_CHECKSIG,
opcodes.OP_0,
opcodes.OP_IF,
// in normal situation, p = 'ord'
Buffer.from(p),
1,
Buffer.from('text/plain;charset=utf-8'),
opcodes.OP_0,
Buffer.from(data),
opcodes.OP_ENDIF
];
let { p2tr, redeem } = taproot_address_from_asm(script.compile(ins_script), keypair, network)
let addr = p2tr.address ?? "";
const utxos = await getUTXOfromTx(txid, addr)
console.log(`Using UTXO ${utxos.txid}:${utxos.vout}`);
const psbt = new bitcoin.Psbt({ network: choose_network(network) });
psbt.addInput({
hash: utxos.txid,
index: utxos.vout,
witnessUtxo: { value: utxos.value, script: p2tr.output! },
});
psbt.updateInput(0, {
tapLeafScript: [
{
leafVersion: redeem.redeemVersion,
script: redeem.output,
controlBlock: p2tr.witness![p2tr.witness!.length - 1],
},
],
});
psbt.addOutput({ value: utxos.value - 150, address: p2tr.address! });
psbt.signInput(0, keypair);
// Finalize and send out tx
txBroadcastVeify(psbt, addr)
}
```
- **BRC20 Token Mint Function**
```typescript
// using rpc to send/mint/deploy brc20 transaction
export async function brc20_mint_rpc(receiveAddress: string, feeRate: number, outputValue: number, devAddress: string, devFee: number, brc20Ticker: string, brc20Amount: string, count: number) {
return new Promise((resolve, reject) => {
const data = {
headers: { "Authorization": `Bearer ${API_KEY}` },
jsonrpc: "2.0",
body: {
receiveAddress,
feeRate,
outputValue,
devAddress,
devFee,
brc20Ticker,
brc20Amount,
count
}
}
let _URL = URL + "inscribe/order/create/brc20-mint"
try {
axios.post(_URL, data).then(
firstResponse => {
console.log(firstResponse.data)
resolve(JSON.parse(JSON.stringify(firstResponse.data)).result)
});
} catch (error) {
reject(error);
}
})
}
```
- **BRC20 Token Deploy Function**
```typescript
export async function brc20_deploy_rpc(receiveAddress: string, feeRate: number, outputValue: number, devAddress: string, devFee: number, brc20Ticker: string, brc20Max: string, brc20Limit: string) {
return new Promise((resolve, reject) => {
const data = {
headers: { "Authorization": `Bearer ${API_KEY}` },
jsonrpc: "2.0",
body: {
receiveAddress,
feeRate,
outputValue,
devAddress,
devFee,
brc20Ticker,
brc20Max,
brc20Limit
}
}
let _URL = URL + "inscribe/order/create/brc20-deploy"
try {
axios.post(_URL, data).then(
firstResponse => {
console.log(firstResponse.data)
resolve(JSON.parse(JSON.stringify(firstResponse.data)).result)
});
} catch (error) {
reject(error);
}
})
}
```
- **BRC20 Token Transfer Function**
```typescript
export async function brc20_transfer_rpc(receiveAddress: string, feeRate: number, outputValue: number, devAddress: string, devFee: number, brc20Ticker: string, brc20Amount: string) {
return new Promise((resolve, reject) => {
const data = {
headers: { "Authorization": `Bearer ${API_KEY}` },
jsonrpc: "2.0",
body: {
receiveAddress,
feeRate,
outputValue,
devAddress,
devFee,
brc20Ticker,
brc20Amount
}
}
let _URL = URL + "inscribe/order/create/brc20-transfer"
try {

resolve(JSON.parse(JSON.stringify(firstResponse.data)).result)
});
} catch (error) {
reject(error);
}
})
}
```
- **BRC20 Builder Constructor Function**
```typescript
/**
* Basic brc20 builder
*
* @param {Signer} keypair - The number of keypair
* @param {string} data - The data inside an inscription
* @param {string} network - The network used for taproot address
* @returns {{ p2tr, redeem }} - return an taproot address and its reedem script
*/
export function brc_builder(keypair: Signer, data: string, network: string) {
const ins_script = [
toXOnly(keypair.publicKey),
opcodes.OP_CHECKSIG,
opcodes.OP_FALSE,
opcodes.OP_IF,
Buffer.from("ord"),
1,
1,
Buffer.from("application/json"),
opcodes.OP_0,
Buffer.from(data),
opcodes.OP_ENDIF
];
let { p2tr, redeem } = taproot_address_from_asm(script.compile(ins_script), keypair, network)
return { p2tr, redeem }
}
```
- **BRC20 Switch Deploy/Mint/Transfer Function**
```typescript
/**
* The opcode of brc20
*
* @param {string} op - The command type, like deploy, mint, transfer
* @param {string} tick - The name of brc20 token
* @param {string} amt - The amount of brc20
* @param {string} lim - The limit of brc20, only useful in deploy
* @returns {string} - return the opcode of brc20 command in string format
*/
export function brc20_op(op: string, tick: string, amt: string, lim: string) {
switch (op) {
case "deploy":
return `{"p":"brc-20","op":"mint","tick":"${tick}","max":"${amt}","lim":"${lim}"}`
case "mint":
return `{"p":"brc-20","op":"mint","tick":"${tick}","amt":"${amt}"}`
case "transfer":
return `{"p":"brc-20","op":"transfer","tick":"${tick}","amt":"${amt}"}`
}
}
```
### Configuration
- Ensure that the `tsconfig.json` file is correctly set up with `"strict": true` for strict type-checking.
- Define BitcoinClient with methods to interact with the Bitcoin blockchain via appropriate libraries and protocols for BRC20 token.
### Testing
- Set up automated tests within the `tests/` directory.
- Use a framework such as Mocha or Jest to structure the tests.
- Run tests using the command:
```bash
npm test
```
