How to get a private key from seed phrase on solana?

I stored public key and seed phrase in safe place, but not the private key. When I add my wallet on phantom, it asks to add private key instead of seed phrase. Any solutions? Thank you.

Solution

  • Solution 1: navigate to the keypair json on your system. i.e. .config/solana/id.json. Then you can find out the array for the private key.

    Solution 2: you can use solana web3 SDK.

      let seed = Uint8Array.from(
    SEED_STRING.split(",")
  ).slice(0, 32);

  // create keypairs
  let KEYPAIRS = web3.Keypair.fromSeed(seed);
  console.log(KEYPAIRS.privateKey);
