Morpho Blue Bundlers

Morpho Blue is a new lending primitive that offers better rates, high capital efficiency and extended flexibility to lenders & borrowers. morpho-blue-bundlers hosts the logic that builds alongside the core protocol like MetaMorpho and bundlers.

Structure

Each Bundler is a domain-specific abstract layer of contract that implements some functions that can be bundled in a single call by EOAs to a single contract. They all inherit from CoreBundler that enables bundling multiple function calls into a single multicall(bytes[] calldata data) call to the end bundler contract. Each chain-specific bundler is available under their chain-specific folder (e.g. ethereum).

Some chain-specific domains are also scoped to the chain-specific folder, because they are not expected to be used on any other chain (e.g. DAI and its specific permit function is only available on Ethereum - see EthereumPermitBundler).

User-end bundlers are provided in each chain-specific folder, instanciating all the intermediary domain-specific bundlers and associated parameters (such as chain-specific protocol addresses, e.g. EthereumBundlerV2).

Getting Started

Install dependencies with yarn.

Run tests with yarn test:forge --chain <chainid> (chainid can be 1 or 8453).

Note that the EthereumBundlerV2 has been deployed with 80 000 optimizer runs. To compile contracts with the same configuration, run FOUNDRY_PROFILE=ethereumBundlerV2 forge b.

Audits

All audits are stored in the audits' folder.
