Getting Started\n\nnpm:\n\n```\nnpm install @synfutures/oyster-sdk\n```\n\nyarn:\n\n```\nyarn add @synfutures/oyster-sdk\n```\n\n## 📝 Environment Variables Requirement\n\nThis 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](https://www.npmjs.com/package/@derivation-tech/web3-core).\n\n## 👀 Note\n\n1. Before carrying out operations like trade, place, etc., please check the user's allowance for `Gate`.\n2. 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.\n\n## ABIs\n\nThe SDK provides ABIs of several important contracts to facilitate your interaction with SynFuturesV3. You can obtain them in the following ways:\n\n- Extract the original JSON files directly from the SDK. The paths are as follows:\n\n```shell\n/oyster-sdk/src/abis/CexMarket.json\n/oyster-sdk/src/abis/Config.json\n/oyster-sdk/src/abis/DexV2Market.json\n/oyster-sdk/src/abis/Gate.json\n/oyster-sdk/src/abis/Instrument.json\n/oyster-sdk/src/abis/Observer.json\n```\n\n- Use them directly from the SDK\n\n```typescript\nimport { INSTRUMENT_ABI } from '@synfutures/oyster-sdk';\nimport { Contract } from 'ethers';\n\n// Print the ABI of the Instrument contract\nconsole.info(JSON.stringify(INSTRUMENT_ABI, null, 2));\n\n// Use INSTRUMENT_ABI directly from the SDK\nnew Contract(address, INSTRUMENT_ABI, signerOrProvider);\n```\n\n## Examples\n\n1.

BLAST_RPC=https://rpc.ankr.com/blast into the .env file where you run your command.\n- Also set your private key ALICE_PRIVATE_KEY=your_own_private_key if you want to send transactions.\n- Or you can set your provider and wallet directly in the code.\n\n```ts\nconst sdk = SynFuturesV3.getInstance('blast');\nsdk.setProvider(new ethers.providers.JsonRpcProvider('https://rpc.ankr.com/blast'));\nconst keystore = readFileSync('keystore.json', 'utf-8');\nconst signer1 = ethers.Wallet.fromEncryptedJsonSync(keystore, 'password');\nconst signer2 = ethers.Wallet.fromMnemonic(\n 'test test test test test test test test test test test test',\n \"m/44'/60'/0'/0/1\",\n);\nconst signer3 = new ethers.Wallet('private key');\n```\n\n### Query instruments and pairs information\n\n```ts\nimport { ethers } from
