📝Getting tokens

Specific devnet SPL tokens are required to test fermi

First, create and initialise your associated token account, and your openorders account:

const authorityPCTokenAccount = await spl.getAssociatedTokenAddress(  
      new anchor.web3.PublicKey(pcMint),
        connectedPublicKey,
        false,
      );
    
      console.log(authorityPCTokenAccount.toString());
      let openOrdersPda;
      let openOrdersPdaBump;
      [openOrdersPda, openOrdersPdaBump] =
      await anchor.web3.PublicKey.findProgramAddress(
        [
          Buffer.from('open-orders', 'utf-8'),
          new anchor.web3.PublicKey(marketPda).toBuffer(),
          connectedPublicKey.toBuffer(),
        ],
        program.programId,
      );

Next, ask the admin to mint some spl tokens to your accounts. Alternatively, if you're testing on your own deployment, you can use the adapted code in branch 'wallet-admin' to give yourself airdrops of SPL tokens

const custom = new anchor.web3.PublicKey("42Dg1Y97EQuwAfj4ovzD76myhRE5ZJkCySuTzHoRcxxH");

const custom_ata_coin = new anchor.web3.PublicKey("H2cZK8LEgqEBUL52Px6fkTWMVAHrhVPi5VWwztRmRw6u");

const custom_ata_pc = new anchor.web3.PublicKey("54EjXUWQitej4UZYYbb4QNJLN1nAFmwW7AkuC19UGQoV");
    

    console.log("sent to");
    console.log(custom_ata_pc.toString());

    await createAssociatedTokenAccount(
      provider,
      pcMint,
      custom_ata_pc,
      custom,
    );

    await mintTo(
      provider,
      pcMint,
      custom_ata_coin,
      BigInt('10000000000'),
    );
    
      await createAssociatedTokenAccount(
      provider,
      pcMint,
      custom_ata_pc,
      custom,
    );
    
    await mintTo(
      provider,
      coinMint,
      customCoinTokenAccount,
      BigInt('100000000000'),
    ); 
    console.log("airdrop done");
