Ensuro - Decentralized capital for insurance

Ensuro is a decentralized protocol that manages the capital to support insurance products.

It allows liquidity providers (LPs) to deposit capital (using stable coins) that will fulfill solvency capital requirements of underwritten policies. This capital will be deposited in different pools (eTokens) according to provider's cashback period preferences. The capital will be locked for the duration of policies and will report profits to the LPs in the form of continous interest.

On the policy side, the policies are injected into the protocol by Risk Modules. Each risk module represent an Ensuro partner and a specific insurance product and is implemented with a smart contract (inherited from RiskModule). Each risk module has two responsabilities: pricing and policy resolution. Also, the RiskModule smart contract stores several parameters of the risk module such as Ensuro and Risk Module fees, capital allocation limits, etc.

Contracts

Governance

The protocol uses three levels of access control, plus a guardian role. The roles are managed by the PolicyPoolConfig smart contract.

Development

For coding the smart contracts the approach we took was prototyping initially in Python (see folder prototype), and later we coded in Solidity. The tests run the same test case both on the Python prototype code and the Solidity code. To adapt the Solidity code that is called using brownie, we have some glue code implemented in tests/wrappers.py.

The development environment is prepared for running inside a docker container defined in the Dockerfile. Also you can launch the docker environment using invoke tasks, but before you need to run pip install inv-py-docker-k8s-tasks to install a package with common tasks for coding inside docker. Then with inv start-dev you should be able to launch the docker environment. Then you can run specific tasks:

• inv tests: runs the test suite
• inv shell: opens a shell inside the docker container

Also the docker container is prepared to run hardhat. This will be used probably for deployment scripts and perhaps some aditional tests.
