Our take
Onramper
Onramper provides a specialized aggregation layer for fiat to crypto purchases. Instead of serving as a single standalone brokerage, the platform connects decentralized applications, mobile wallets, and platforms to a wide network of licensed fiat gateways. This setup allows buyers to compare quote rates, access alternate payment methods, and use fallback routes if a specific regional gateway declines a transaction.
Because Onramper functions strictly as an orchestration interface, it does not custody user assets or process fiat banking balances directly. Cryptocurrency settlements route straight to external self custody addresses provided during checkout. The tradeoff lies in fee variance and customer service boundaries. Transaction costs, verification requirements, and settlement speeds remain tied to the specific partner processing each transaction, requiring buyers and integrating platforms to manage multiple partner policies.
relai
Relai positions itself as an accessible gateway for European residents seeking straightforward Bitcoin exposure with genuine self-custody from day one. The mobile platform bypasses traditional custodial holding balances, settling all completed purchases directly to private seed phrases generated on user devices. This architectural choice removes central counterparty custody risk while maintaining approachable workflows for scheduled dollar-cost averaging orders.
The service structure makes deliberate compromises. The platform focuses exclusively on Bitcoin, ignoring broader multi-asset ecosystems and smart contract protocols. Base transaction costs remain higher than wholesale order-book exchanges, though fee reductions apply to larger volumes and recurring plans. For cost-conscious savers who prioritize direct key ownership over complex trading tools, Relai provides a clear and focused entry path.
