Solidity: 1.0.0 (Mainnet)

A coverage pool is a flexible new money lego that can be used as a back-stop or "buyer of last resort" in on-chain financial systems.

Across DeFi, young systems are hiding and shuffling around risk for perceived security. These risks are part of what drives yield; but stacked atop each other, risks are multiplied. Coverage pools can be used in these systems to offset risk, allowing human or algorithmic governance to reward underwriters. They’re designed as building blocks rather than a standalone products, allowing system designers and communities to tailor risk management to their circumstances.

solidity/v1.0.0 is the first mainnet release of Coverage Pool with KEEP used as an underwriter token and tBTC v1 Risk Manager for deposits being liquidated.

In addition to the primary contracts, we're providing the release commit hash (which corresponds to the solidity/v1.0.0 tag) and associated signatures from the deployment team.
