@luagio/mango-client v3.3.24
Mango v3 Client Library
JavaScript client library for interacting with Mango Markets DEX v3.
Installation
Using npm:
npm install @blockworks-foundation/mango-client
Using yarn:
yarn add @blockworks-foundation/mango-client
Usage Example
This example assumes that you have a wallet that is already setup with devnet tokens. The private key should be stored in ~/.config/solana/devnet.json
. Visit https://v3.mango.markets/ and connect with the wallet to fund your margin account so that you can place orders. You can find the full source code in example.ts.
// Fetch orderbooks
const bids = await perpMarket.loadBids(connection);
const asks = await perpMarket.loadAsks(connection);
// L2 orderbook data
for (const [price, size] of bids.getL2(20)) {
console.log(price, size);
}
// L3 orderbook data
for (const order of asks) {
console.log(
order.owner.toBase58(),
order.orderId.toString('hex'),
order.price,
order.size,
order.side, // 'buy' or 'sell'
);
}
// Place order
await client.placePerpOrder(
mangoGroup,
mangoAccount,
mangoGroup.mangoCache,
perpMarket,
owner,
'buy', // or 'sell'
39000,
0.0001,
'limit', // or 'ioc' or 'postOnly'
);
// retrieve open orders for account
const openOrders = await perpMarket.loadOrdersForAccount(
connection,
mangoAccount,
);
// cancel orders
for (const order of openOrders) {
await client.cancelPerpOrder(
mangoGroup,
mangoAccount,
owner,
perpMarket,
order,
);
}
// Retrieve fills
for (const fill of await perpMarket.loadFills(connection)) {
console.log(
fill.owner.toBase58(),
fill.maker ? 'maker' : 'taker',
fill.baseChange.toNumber(),
fill.quoteChange.toNumber(),
fill.longFunding.toFixed(3),
fill.shortFunding.toFixed(3),
);

/* TODO list 1. mark price 2. oracle 3. liquidator 4. order book 5. crank 6. market makers 7. insurance fund 8. Basic DAO 9. Token Sale 10.
Crank keeps the oracle prices updated Make adding perp markets very easy
Designs Single Margin-Perp Cross A perp market crossed with the equivalent serum dex spot market with lending pools for margin
find a way to combine multiple of these into one cross margined group
Write an arbitrageur to transfer USDC between different markets based on interest rate
Multi Perp Cross Multiple perp markets cross margined with each other Pros:
Cons: 1. Have to get liquidity across all markets at once (maybe doable if limited to 6 markets) 2. Can't do the carry trade easily 3.
