Serum DevTools 🛠️

A developer tooling SDK for building on serum-dex.

Prerequisites

You will need to use the FileKeypair class that extends the Keypair class from @solana/web3.js to provide easy file-based keypair management, which is required for the market making features provided by this package.

``javascript
const owner = FileKeypair.generate("./scripts/keys/owner.json");

const airdropSig = await connection.requestAirdrop(
owner.keypair.publicKey,
10 * LAMPORTS_PER_SOL,
);
await connection.confirmTransaction(airdropSig);
`

You need to have a serum-dex program deployed on the cluster you wish to interact with.

You can either,

- Use the serum-dev-tools CLI to deploy the program.

- use the already deployed serum-dex programs, 9xQeWvG816bUx9EPjHmaT23yvVM2ZWbrrpZb9PusVFin on mainnet-beta and DESVgJVGajEgKGXhb6XmqDHGz3VjdgP7rEVESBgxmroY on devnet.

`javascript
const connection = new Connection("http://localhost:8899", "confirmed");

const dexAddress = new PublicKey(
"7zo7HCQAZPRb4pYiQQ6fLjC8ssN3E8LkavVs8JUA5NMn",
);

const dex = new Dex(dexAddress, connection);
`

$3

`javascript
const baseCoin = await dex.createCoin(
"SAYA",
9,
owner.keypair,
owner.keypair,
owner.keypair,
);

const quoteCoin = await dex.createCoin(
"SRM",
9,
owner.keypair,
owner.keypair,
owner.keypair,
);

// Fund the FileKeypair object to place orders.

await baseCoin.fundAccount(1000000, owner.keypair, connection);

await quoteCoin.fundAccount(2000000, owner.keypair, connection);
`

`javascript
const market = await dex.initDexMarket(owner.keypair, baseCoin, quoteCoin, {
lotSize: 1e-3,
tickSize: 1e-2,
});
`

`javascript
dex.runMarketMaker(market, owner, {
durationInSecs: 30,
orderCount: 3,
initialBidSize: 1000,
baseGeckoSymbol: "solana",
quoteGeckoSymbol: "usd",
});
