defisaver-v3-contracts

All the contracts related to the Defi Saver ecosystem.

A detailed overview of the code can be found at Defi Saver Docs.

Install

Run yarn in the repository folder.
You will also need to create a .env file based on .env.example and fill it in with the appropriate API keys.
For a quick start, you can copy .env.example (which contains default values) and rename it to .env.

Foundry tests

1. Ensure you have Foundry installed (check with forge --version).
2. Set the ETHEREUM_NODE variable in the .env file with a mainnet RPC URL.
3. Install dependencies:

   forge install foundry-rs/forge-std dapphub/ds-test --no-commit

4. Run tests:

   forge test

All tests are run from a forked state of mainnet. You can specify the block number in test-sol/config/config.json.

To run only core tests:

forge test --mc TestCore

To run coverage on core:

bash run-core-coverage.sh

Hardhat tests

Before running tests, compile all contracts:

npx hardhat compile

In hardhat.config.js hardhat network will fork mainnet by default.

You can change the block number from which the fork starts in the Hardhat config; note that if it starts from an old state, some tests might not work.

Running core tests:

npx hardhat test ./test/run-core-tests.js

Example of running tests with a specified network:

npx hardhat test ./test/aaveV3/full-test.js --network hardhat

Custom hardhat tasks

npx hardhat changeRepoNetwork [current-network-name] [new-network-name] - will change which contract the helper contracts import and extend

npx hardhat customFlatten [contract-name] - will flatten contract that is ready for deployment and put it in contracts/flattened folder

npx hardhat customVerify [contract-address] [contract-name] --network [hardhat-settings-network-name] - will verify on etherscan if a contract was deployed using a single file from customFlatten task

npx hardhat fladepver [contract-name] [gas-in-gwei] [nonce (optional)] --network [hardhat-settings-network-name] - will flatten to a single file (save it in contracts/flattened), deploy from it and then verify it on etherscan

npx hardhat encryptPrivateKey - will encrypt the key with the secretWord. Put the output in .env as ENCRYPTED_KEY. Later on during deployment process it will ask you for secret word to decrypt the key for deployment use.

npx hardhat deployOnFork [Contract1] [Contract2] [ContractN] - deploys the specified contracts on a Tenderly fork. Before running this command, add the Tenderly fork ID to the .env file where you want to deploy.
