Configuration

interface GmxSdkConfig {
  chainId: number;
  rpcUrl: string;
  oracleUrl: string;
  subsquidUrl?: string;
  account?: string;
  publicClient: PublicClient;
  walletClient: WalletClient;
  tokens?: Record<string, Partial<Token>>;
  markets?: Record<
    string,
    {
      isListed: boolean;
    }
  >;
}

Tokens customization

If you need to override some field in tokens, just pass extension object in SDK config:

const sdk = new GmxSdk({
  ...arbitrumSdkConfig,
  tokens: {
    "0x912CE59144191C1204E64559FE8253a0e49E6548": {
      name: "My Custom Name for ARB",
    },
  },
});

Here and further, name field in tokens data object will be taken from the extension object.

Markets customization

To enable/disable market in SDK use config field `markets

const sdk = new GmxSdk({
  ...arbitrumSdkConfig,
  markets: {
    "0x47c031236e19d024b42f8AE6780E44A573170703": {
      isListed: false,
    },
  },
});

Examples

Open long position

import type { IncreasePositionAmounts } from "@gmx-io/sdk/types/orders";

const { marketsInfoData, tokensData } = await sdk.markets.getMarketsInfo();

if (!marketsInfoData || !tokensData) {
  throw new Error("No markets or tokens info data");
}

const marketInfo = marketsInfo["0x47c031236e19d024b42f8AE6780E44A573170703"];
