wtf is seaport?

Seaport is the underlying technology that powers the buying and selling of NFTs (non-fungible tokens). Created by OpenSea, it is a set of rules, or a protocol, that lets people safely and efficiently trade digital items with each other. Instead of trusting a single company to hold your items or money during a transaction, this protocol ensures the swap happens securely and automatically. At its core, every listing in this system is built around a trade. A seller creates a listing that specifies what they are offering to give up, and exactly what they want to receive in return. The interesting part is that a trade does not have to be a simple one-for-one swap. A single listing can include multiple items being offered and multiple items expected in return, and those incoming items can even be routed to different recipients. A marketplace builder, a crypto founder, or a developer creating a new digital art platform would use this project to handle their users' transactions. For example, if a creator wants to build a niche marketplace for digital trading cards, they can plug into this protocol rather than building a secure trading system from scratch. It is already deployed across many popular blockchain networks like Ethereum, Polygon, Arbitrum, and Avalanche, so a builder can tap into a wide, existing audience. The project places a heavy emphasis on security and efficiency. It was audited by an independent security firm called Trail of Bits, which verified that the system is safe from major flaws that could lead to lost funds. The codebase also requires 100% test coverage for any contributions, meaning every possible scenario is checked to ensure the software behaves exactly as intended before changes are accepted.
