Write functions

Here is the examples of signing write transaction from local keypair, that is feasible only on server. For examples on how to sign write transaction in browser using sollet browser extention visit frakt-library-browser-example for a full example.

Buy art local keypair signed

  import { buyArt } from 'frakt-client';
  import {
    Connection,
    PublicKey,
  } from '@solana/web3.js';

  const fraktProgramPubKey = new PublicKey("6zcw5qXiCjScAxYLhxhuPgAo69PSoDijpnWTDGmDVDbv")
  const adminPubKey = new PublicKey("DQfi54Fspjfi6VyMH1iSDyYAcui2hUF1QRbQ1GM7N1uo")
  const aliceKeypair = readKeypairFromPath(<PATH_TO_YOUR_KEYPAIR>) 

  const connection = new Connection("https://api.devnet.solana.com", "processed")

  void await buyArt(aliceKeypair.publicKey, fraktProgramPubKey, adminPubKey,
    async (txn) => void connection.sendTransaction(txn, [aliceKeypair]), { connection })

See example/tests/getArts.js for a full example.

Mint art local keypair signed

  import { mintArt } from 'frakt-client';
  import {
    Connection,
    PublicKey,
  } from '@solana/web3.js';

  const fraktProgramPubKey = new PublicKey("6zcw5qXiCjScAxYLhxhuPgAo69PSoDijpnWTDGmDVDbv")
  const adminKeypair = readKeypairFromPath(__dirname + "/keys/admin.json")
  const userPubKey = new PublicKey("DYEfeSZz6fyVyGVefXiKisu94TzQnT2UG8Rc1ZZ2wAWb")
  const artPubKey = new PublicKey("Hsx9yQkqiL5A6vTf2QRjcVBDCzNKTssgiagBVbWXmtd7")
  const connection = new Connection("https://api.devnet.solana.com", "processed")

  void await mintArt({
    shape: 1,
    color: 2,
    art_hash: 2, // Hash of figure+color combination in ranges
    circles_amount: 7,
    fractial_iterations: 14,
    min_rad_low_limit: 3,
    min_rad_high_limit: 8,
    max_rad_low_limit: 102,
    max_rad_high_limit: 305,

    color_rarity: 70,
    image_url: "", // wip anyway
  }, adminKeypair.publicKey, userPubKey, artPubKey, fraktProgramPubKey,
  async (txn) => void connection.sendTransaction(txn, [adminKeypair]),
  { connection })
