To sign and broadcast a transaction to the Bitcoin network, follow these steps from the README of this repository:

Initialize the service by installing dependencies.
In the config.js file, set your private key and specify the network.
Sign the transaction using the code.
Finally, send the signed transaction to the Bitcoin network by making a POST request to /api/v1/babylon-btc/{network}/transaction/send.

Example request (for sigNet network):

curl --request POST \
     --url https://api-test.p2p.org/api/v1/babylon-btc/signet/transaction/send \
     --header 'accept: application/json' \
     --header 'authorization: Bearer <token>' \
     --header 'content-type: application/json' \
     --data '

     "maxFee": 1000000
     }`

transactionHex — signed transactionin the hexadecimal format which needs to be broadcasted to the network.
maxFee — maximum fee in SATOSHI that can be charged for processing the transaction (1 BTC = 10⁸ SATOSHI).
