Overview

The escrow contract holds funds from a buyer until conditions are met, then releases them to the seller. This is a foundational pattern for marketplaces and peer-to-peer trading.

Key patterns:

  • State machine: Created -> Deposited -> Confirmed -> Released/Refunded
  • Multi-party authorization: Buyer and seller have different permissions
  • Conditional execution: Funds release only after buyer confirmation
  • Refund mechanism: Buyer can reclaim before confirming
