SDK for fetching DeFi Saver strategies data from the blockchain.

Fetch strategies data from the blockchain, and parse it into a readable format. Use one of the following classes to fetch data for strategies: EthereumStrategies, OptimismStrategies, ArbitrumStrategies or BaseStrategies. Use one of the following classes to fetch data for legacy automation: LegacyMakerAutomation, LegacyAaveAutomation, or LegacyCompoundAutomation. Various services and constants also available for use.

Usage

const ethereumStrategies = new EthereumStrategies({
  provider: WEB3_PROVIDER_HERE,
});

const subscriptions = await ethereumStrategies.getSubscriptionsFor(
  // Pass one or multiple owner addresses, or use getSubscriptions method to fetch all subscriptions
  ['0x000000000000000000000000000000000000dEaD'],
  {
    fromBlock: 0,
    toBlock: 'latest',
    mergeSubs: true, // Used for merging subscriptions with same strategy ID (e.g. boost and repay)
    enabledOnly: true,
    unexpiredOnly: true, // Referring to exchange subscriptions
  }
);

// Do what you would like with subscriptions

Development - How to add new strategies?

• Add strategy/bundle ID to ./src/types/enums.ts, and create Identifiers if needed
• Add strategy/bundle info to ./src/constants/index.ts
• Add encoding/decoding to the following files:
  • ./src/services/strategySubService.ts
  • ./src/services/subDataService.ts
  • ./src/services/triggerService.ts
• Write parsing for the strategy in ./src/services/strategeiesService.ts and add assign it to const parsingMethodsMapping
• Write tests for each method
• Run tests with yarn test or yarn test fileName for a specific file (e.g. yarn test utils)
• Congrats! 🥳

Testing

npm run test - Run all tests

npm run test-single --name=your_test_name - Run single test for specified name e.g. for MyTest.test.ts test name is MyTest
