Bonsai Lend

Note: This software is not production ready. Do not use in production.

This is a proof-of-concept implementation of a simplified lending protocol that encapsulates all app-specific logic as a RISC Zero Bonsai zkVM program. The zkVM program computes the new state of the protocol and all required asset transfers, and only token transfers and the storage of an accumulator of the resulting state (after the ZKP has been successfully verified) are done on-chain. This architecture offloads computationally intensive state transitions and allows for the reuse of the protocol core logic on different domains (even non-EVM domains).

Dependencies

First, install Rust and Foundry, and then restart your terminal. Next, you will need to install the cargo risczero tool:

cargo install cargo-risczero

For the above commands to build successfully you will need to have installed the required dependencies.

sudo apt install curl build-essential libssl-dev pkgconf

Next we'll need to install the risc0 toolchain with:

cargo risczero install

Quick Start

First, install the RISC Zero toolchain using the instructions above.

• Use make test-dev for running the tests without the Bonsai API

• Use make test for running the tests with the Bonsai API

  • Create a .env file that contains the Bonsai API credentials:
  • Note: To request an API key complete the form here.

    export BONSAI_API_KEY=<BONSAI_API_KEY>
