I’ll start by updating the escrow contract to support multiple milestones, each with its own status, payout amount, and deadline. Then I’ll implement logic for partial fund releases per milestone, along with time based validation so overdue milestones can be flagged or expired automatically.

I have experience working with smart contract payment flows and will make sure the Milestone system in TaskChain is safe, predictable, and easy to extend.
