This is the repository for Spark Lend deploy scripts and custom code. Primarily this repository acts as an orchestration toolkit for deploying and managing Spark Lend instances across many chains. Apart from the custom code below everything is combined from third party vendors.
Run tests: make test
Deploy Spark Lend: ETH_RPC_URL=<YOUR RPC ENDPOINT> make deploy
Deploy Config Engine: ETH_RPC_URL=<YOUR RPC ENDPOINT> make deploy-engine
Deploy Spark Lend (Custom Instance): INSTANCE_ID=<Custom Instance Name> ETH_RPC_URL=<YOUR RPC ENDPOINT> make deploy
Deploy Config Engine (Custom Instance): INSTANCE_ID=<Custom Instance Name> ETH_RPC_URL=<YOUR RPC ENDPOINT> make deploy-engine
Deploy Pool Upgrade: ETH_RPC_URL=<YOUR RPC ENDPOINT> make deploy-pool (Please note you need to set the proper POOL_REVISION in Pool.sol)
- Install local instance of sourcify via https://docs.sourcify.dev/docs/run-locally/#running-the-server
- Default
.env.devis mostly fine, but updateNODE_URL_MAINNETto be a valid rpc endpoint. - Start the server
npm run server:start.
Run ./validate-deploy.sh path/to/broadcast.json (Be sure to forge build with proper settings first)
If you want to delete previously verified contracts then run rm -rf /tmp/sourcify/repository/contracts/*
A special interest rate strategy is used for the DAI market which anchors to the Dai Savings Rate (DSR). It is a flat rate up to the debt ceiling. If Maker needs to bring back liquidity by lowering the debt ceiling then the interest rate will spike to ensure user deposits and borrow repayments.

This is the oracle for sDAI which will take the input of a standard DAI price feed and convert it via the pot.chi factor.
Fork of the AaveMigrationHelper which has some extra features like converting from USDC to DAI automatically.
