Port Finance

What Port Finance does

Port Finance is a decentralized finance (DeFi) protocol founded in May 2021 and operated by a team of 1-10 employees based in New York. It is built on the Solana blockchain and provides a suite of financial primitives — variable and fixed-rate lending, borrowing, a swap aggregator, cross-chain bridging, and portfolio tracking — accessed through a single self-serve web application called the Port App. Its distinguishing technical feature is cross-margin functionality, which margining all borrowing and lending positions together to improve collateral efficiency, and the protocol reports transaction costs of less than $0.01 per transaction.

The platform targets individual cryptocurrency users and DeFi enthusiasts who would otherwise interact with multiple separate protocols for lending, swapping, and bridging. Port Finance earns revenue primarily through the interest spread on lending and borrowing activity, with transaction fees structured to be sub-penny. Distribution is entirely product-led and community-driven, relying on Discord, Twitter, documentation, and a lightpaper rather than a sales force.

The company has completed a $1.0 million seed round in July 2021 from GSR, Rarestone Capital, and Valhalla Capital, and has pursued multiple security audits (OtterSec, Kudelski, Slowmist, Bramah System) alongside an Immunefi bug bounty program. No further funding rounds, acquisitions, or leadership additions are disclosed in the available data, and the company remains private with no parent entity.
