What this does:

Goerli will be deprecated by end of year.

Prepare shift of root contracts on Lynx to use Sepolia instead of Goerli. The child contract deployments remain the same, so should have no impact on existing rituals etc. It should be a relatively simple transition of updating the lynx contract registry in nucypher and updating lynx nodes to use sepolia endpoints.

• Updated root constructor parameters based on latest used for mainnet deployment
• Updated root parameters / scripts to use Sepolia instead of Goerli
• Deployed Lynx contracts to Sepolia and update root part of contract registry (remove entries for chain 5)
• Verified contracts on Sepolia
  • LynxStakingToken
  • MockPolygonRoot
  • TACo Application (Proxied)
  • TestnetThresholdStaking
• Executed configure_staking script on Sepolia of Lynx nodes
• Executed confirm_operator_address script on Sepolia for Lynx nodes.
