stETH as Anchor collateral

This repo contains Ethereum contracts for integrating stETH as a collateral into the Anchor protocol in the form of bETH token. Currently it assumes the deployed Shuttle bridge between Ethereum and Terra networks.

Contracts

  • bEth bETH token contract
  • AnchorVault a contract allowing to convert between stETH and bETH
  • RewardsLiquidator a contract for selling stETH rewards to UST
  • InsuranceConnector a contract for obtaining the total number of shares burnt for the purpose of insurance/cover application from the Lido protocol
  • BridgeConnectorShuttle an adapter contract for communicating with the Terra Shuttle bridge

RewardsLiquidator, InsuranceConnector and BridgeConnectorShuttle contracts are installed as delegates to the AnchorVault contract and can be replaced by the vault admin.
