Contact the Helio team for your API key and follow the steps below.

Step 1: Prepare Tip Instruction

Add a tip instruction to your transaction to prioritise it:

/**
 * This is an example of our Blocklander wallet. 
 * Always use the API to get the latest Blocklander wallets. 
 * Otherwise, you might use a deprecated wallet.
 */
const TIP_WALLET = new PublicKey("HYseAPq3ZPYzA35hLsEgmdsKCZQ3P7FBCcCPPytRtyTz"); 
const MIN_TIP_LAMPORTS = 500_000;

const tipIx = SystemProgram.transfer({
    fromPubkey: signer.publicKey,
    toPubkey: TIP_WALLET,
    lamports: MIN_TIP_LAMPORTS,
});

Step 2: Get the Latest Tip Wallets

Use our API to retrieve the current list of tip wallets:

curl 'https://api.btftx.io/v1/blocklander/wallets?api-key=<Your API Key>'

Example Response:

{"wallets":["HYseAPq3ZPYzA35hLsEgmdsKCZQ3P7FBCcCPPytRtyTz"]}

Step 3: Submit Your Transaction

You can easily submit your Blocklander transaction:

RPC-like URL Method

Use our RPC URL with the standard Solana sendTransaction method:

const connection = new Connection('https://api.btftx.io/v1/blocklander/rpc?api-key=<Your API Key>');
signature = await connection.sendTransaction(signedTx);

Example Success Response:

{
 "status":"SUCCESS",
 "transactionSignature":"2Hmt6gPYTANxseRW3Qp3Ri38xWUMw4pHLfmaiHLTFy1sRJxhC5t4rkCRBWEPsJatbePKabZ562XJevF8pxpseo16"
