Sign and Broadcast Transaction

To complete any staking or withdrawal operation on TON, sign the unsigned transaction provided by the Staking API and broadcast it to the network.

1. Prepare the transaction

Initialize the service by installing dependencies from this repository.
In the ton-sign.ts file, specify the staker account's seed phrase and prepare unsigned transactions in Base64 encrypted format.

2. Sign and broadcast the transaction

Sign the transaction using the code from the repository.
Finally, send the signed transaction to the TON network by making a POST request to /api/v1/ton/{network}/transactions/broadcast.

Example request (for the testnet network):
```
curl --request POST \
     --url https://api.p2p.org/api/v1/ton/testnet/transactions/broadcast \
     --header 'accept: application/json' \
     --header 'content-type: application/json' \
     --data '
{
  "walletVersion": "V4",
  "unsignedTransaction": "te6ccgEBAQEABgAACCiAmCM=",
  "signature": "te6ccgEBAQEABgAACCiAmCM=",
  "publicKey": "7031f1dcbe0f670daf4094d04ff9a7947bc4ac9174a7d470255d1a664e20b7c6"
}
'
```
