Harbour Fiat On/Off-Ramp Infrastructure

Harbour provides B2B API infrastructure that bridges traditional fiat payment rails with blockchain networks, enabling businesses to embed seamless fiat-to-crypto and crypto-to-fiat conversion into their products.

Magic Ramp API

Magic Ramp is Harbour's flagship stablecoin payment API connecting SEPA Instant payment rails with blockchain networks. It enables real-time, bidirectional transfers between traditional bank accounts and Web3 wallets, converting euros to USDC on-chain (or vice versa) in under 30 seconds with fees as low as 0.5%.

• Virtual IBANs: Issue virtual IBAN numbers linked directly to blockchain wallet addresses, making bank-to-wallet transfers a one-click experience
• Instant transfers: Bank-to-wallet and wallet-to-bank transactions via SEPA Instant in under 30–60 seconds
• Multi-blockchain: Supports fiat/stablecoin conversion across multiple blockchain networks in a single API, including Polkadot Asset Hub
• Low fees: Transactions from as low as 0.5%

Harbour Core API

Harbour Core is the foundational payment engine underpinning Harbour's capabilities — a scalable API supporting real-time, low-cost payments between traditional finance and blockchain-based finance.

• Multi-currency: EUR and USDC supported, with expansion to additional stablecoins planned
• Programmable transactions: Automated and recurring payment flows for bespoke financial operations
• Compliance built-in: AML systems and regulatory adherence managed by Harbour, removing compliance burden from integrators
• Scalable infrastructure: Designed for high-volume, enterprise-grade payment operations

Web3 Wallet

For platforms wanting to offer users an integrated fiat and crypto experience, Harbour's Web3 Wallet product provides a unified interface with a unique IBAN per wallet, enabling straightforward bank-to-wallet transfers alongside crypto storage, exchange, and DeFi access.

All three products target B2B customers including Web3 wallet providers, dApp developers, fintech platforms, and enterprises that need to bridge fiat banking infrastructure with blockchain payment rails.
