Harbour

Harbour is an innovative payments platform founded in 2022 that bridges traditional banking and blockchain rails using stablecoins. Headquartered in Lancaster, UK with an EU branch in Poland, the company enables fast, seamless, and affordable money transfers between fiat currencies and cryptocurrency for wallets, platforms, and businesses. Backed by Polygon, Delphi Labs, Haatch, and Blockchain Ventures, Harbour's core mission is to make blockchain technology interoperable with traditional banking infrastructure.

Core Products/Services

Harbour's flagship product, Magic Ramp, is a stablecoin payment system that connects SEPA Instant payment rails with blockchain networks including Polkadot. It enables euros to be sent from any bank account and received as USDC on-chain in under 30 seconds, with fees as low as 0.5%. The system is fully bidirectional — Web3 wallet funds can also be received as euros in traditional bank accounts at the same speed. Developers can issue virtual IBANs linked to wallet addresses, making bank-to-wallet transfers a one-click experience.

Harbour Core is a scalable payment API engine that facilitates real-time, low-cost payments between traditional finance (Web2) and blockchain-based finance (Web3), currently supporting instant transactions in EUR and USDC with plans to expand to additional stablecoins. The API enables fiat/stablecoin conversion across multiple blockchain networks in a single integration and supports programmable, automated, and recurring payment flows.

Harbour also provides a Web3 wallet product aimed at enabling end users to manage fiat banking needs alongside crypto storage, exchange, and DeFi interactions in a unified experience. Harbour handles all the regulatory and compliance complexity, including AML systems, so platform partners can focus on their products.
