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),
);
}
CLI for testing
Create a new mango group on devnet:
init-group <group> <mangoProgramId> <serumProgramId> <quote_mint>
yarn cli init-group mango_test_v2.2 66DFouNQBY1EWyBed3WPicjhwD1FoyTtNCzAowcR8vad DESVgJVGajEgKGXhb6XmqDHGz3VjdgP7rEVESBgxmroY EMjjdsqERN4wJUR9jMBax2pzqQPeGLNn5NeucbHpDUZK
Create a new mango group on devnet with new USDC:
init-group <group> <mangoProgramId> <serumProgramId> <quote_mint>
yarn cli init-group mango_test_v3.1 Hm3U4wFaR66SmuXj66u9AuUNUqa6T8Ldb5D9uHBs3SHd DESVgJVGajEgKGXhb6XmqDHGz3VjdgP7rEVESBgxmroY 3u7PfrgTAKgEtNhNdAD4DDmNGfYfv5djGAPixGgepsPp
Add a stub oracle:
add-oracle <group> <symbol>
yarn cli add-oracle mango_test_v2.2 BTC
Add a pyth oracle:
add-oracle <group> <symbol>
yarn cli add-oracle mango_test_v3.1 BTC --provider pyth
Set stub oracle value = base_price * quote_unit / base_unit:
set-oracle <group> <symbol> <value>
yarn cli set-oracle mango_test_v2.2 BTC 40000
Add a spot-market with existing serum market
add-spot-market <group> <symbol> <mint_pk> --market_pk <market_pk>
yarn cli add-spot-market mango_test_v2.2 BTC bypQzRBaSDWiKhoAw3hNkf35eF3z3AZCU8Sxks6mTPP --market_pk E1mfsnnCcL24JcDQxr7F2BpWjkyy5x2WHys8EL2pnCj9
List and add a spot-market
add-spot-market <group> <symbol> <mint_pk> --base_lot_size <number> --quote_lot_size <number>
yarn cli add-spot-market mango_test_v2.2 BTC bypQzRBaSDWiKhoAw3hNkf35eF3z3AZCU8Sxks6mTPP --base_lot_size 100 --quote_lot_size 10
Enable a perp-maket
add-perp-market <group> <symbol>
