import MerkleDistributor from '@jup-ag/merkle-distributor-sdk';
import { PublicKey } from '@solana/web3.js';
import { AnchorProvider, web3 } from '@coral-xyz/anchor';
import { Connection } from '@solana/web3.js';
const mainnetConnection = new Connection('https://api.mainnet-beta.solana.com');
const mockWallet = new Wallet(new Keypair());
const provider = new AnchorProvider(mainnetConnection, mockWallet, {
commitment: 'confirmed',
});
const merkleDistributor = new MerkleDistributor(provider, {
targetToken: new PublicKey(TARGET_TOKEN), // the token to be distributed.
claimProofEndpoint: 'https://worker.jup.ag/jup-claim-proof',
});
- To claim token with MerkleDistributor
const ixs = await merkleDistributor.claimToken(publicKey);
const { blockhash, lastValidBlockHeight } = await connection.getLatestBlockhash('confirmed');
let transaction = new Transaction({
feePayer: publicKey,
blockhash,
lastValidBlockHeight,
}).add(...ixs);
transaction = await wallet.signTransaction(transaction);
const rawTransaction = transaction.serialize();
const txid = await connection.sendRawTransaction(rawTransaction, {
skipPreflight: true,
});
- To get claim status of a user
