SynFutures V3 SDK

SDK for SynFutures V3

💻 Getting Started

npm:

npm install @synfutures/oyster-sdk

yarn:

yarn add @synfutures/oyster-sdk

📝 Environment Variables Requirement

This package depends on the more fundamental package @derivation-tech/web3-core. Therefore, some environment variables need to be provided as required during runtime. Please refer to here.

👀 Note

1. Before carrying out operations like trade, place, etc., please check the user's allowance for Gate.
2. When interacting with Gate (such as deposit, withdraw), the precision of the token is its own precision. However, when interacting with Instrument, the precision of the token is fixed at 18.

Examples

1. Query instruments and pairs information
2. Query accout information
3. Deposit to Gate
4. Withdraw from Gate
5. Trade
6. Adjust position, withdraw half of the available margin
7. Place order
8. Bulk cancel order
9. Add liquidity
10. Remove liquidity
11. Query user operation history
12. Query pair kline chart data
13. Query pair depth chart data
14. Query pair funding rate data
15. Query user single pair info
16. Get Volume Chart
17. Query Account Portfolio Info
18. Query Account Range History
19. Query Asset Transfer History
20. Query Deposit Withdraw History
21. Estimate Earning APY
22. Query market info
23. Direct trade interface
24. Direct place interface
25. Direct add interface
26. Direct remove interface
27. Direct cancel interface
28. Update pair
29. Settle trader

Prerequisites

To successfully run the blew examples:

• Please put BLAST_RPC=https://rpc.ankr.com/blast into the .env file where you run your command.
• Also set your private key ALICE_PRIVATE_KEY=your_own_private_key if you want to send transactions.
• Or you can set your provider and wallet directly in the code.

const sdk = SynFuturesV3.getInstance('blast');
sdk.setProvider(new ethers.providers.JsonRpcProvider('https://rpc.ankr.com/blast'));
const keystore = readFileSync('keystore.json', 'utf-8');
const signer1 = ethers.Wallet.fromEncryptedJsonSync(keystore, 'password');
const signer2 = ethers.Wallet.fromMnemonic(
    'test test test test test test test test test test test test',
    "m/44'/60'/0'/0/1",
);
const signer3 = new ethers.Wallet('private key');
