SpacePay vs Coinbase Commerce 2026 — Crypto Payment Gateway Comparison

Fees, chain coverage, settlement speed, gas handling, white-label checkout, and compliance — a complete breakdown to help merchants choose between SpacePay and Coinbase Commerce in 2026.

Coinbase Commerce is the payment gateway arm of the world's most recognised crypto exchange. It is easy to deploy, benefits from Coinbase's brand trust, and works out of the box for US-based merchants already using Coinbase. SpacePay is a purpose-built merchant payment infrastructure layer designed for global businesses that need multi-chain acceptance, same-day fiat settlement, and full white-label control.

The two products share a 1% headline processing fee and a simple hosted-checkout model. Beyond that surface similarity they diverge sharply in almost every dimension that matters operationally: which chains customers can pay from, who pays gas, how fast funds reach a bank account, whether the checkout carries a competitor's brand, and whether the integration is built for UK and EU regulatory requirements. This page covers every one of those differences in depth.

Side-by-Side Feature Summary

The table below condenses the most decision-relevant criteria into a single view. Detailed explanations for each row follow in the sections below.

Fees: What You Actually Pay End-to-End

Both SpacePay and Coinbase Commerce advertise a 1% processing fee, which makes them look equivalent at the headline level. In practice the total cost differs significantly depending on how you count network costs, conversion spreads, and withdrawal fees.

SpacePay fee structure

SpacePay charges a single transparent pricing processing fee. There are no network fees on top, no withdrawal fees when funds are sent to a merchant's bank account, no minimum payout threshold, and no exchange rate spread above mid-market when settling in fiat. A merchant receiving £10,000 per month pays £100 in processing fees. The full remaining £9,900 arrives in their bank account the same day.

Coinbase Commerce fee structure

Coinbase Commerce charges 1% on the payment but does not absorb on-chain network fees. When a customer pays with ETH on Ethereum mainnet, they pay the invoice amount plus a gas fee that can range from a few cents to several dollars depending on network congestion. High gas periods can cause customers to underpay (paying the invoice but having the gas deducted from the same transaction output) or simply abandon checkout entirely.

Beyond the 1% processing fee, merchants who want fiat must sell their crypto on Coinbase's exchange. Coinbase charges an additional conversion spread of approximately 0.5–2% depending on asset and account tier. After conversion, withdrawing to a bank account incurs further fees depending on the withdrawal method. For UK merchants using bank transfer, this adds meaningful friction and cost per settlement cycle.

Chain Support: 50+ Blockchains vs Three

Chain support is one of the most consequential differences between the two products. Coinbase Commerce accepts payments on three networks: Ethereum, Polygon, and Base (Coinbase's own L2). These networks represent a substantial share of stablecoin volume but exclude the majority of active crypto users who hold assets on Solana, BNB Chain, Avalanche, Tron, Arbitrum, Optimism, and dozens of other networks.

SpacePay supports over 50 blockchains and multiple tokens. A customer holding USDT on Tron, SOL on Solana, BNB on BSC, or AVAX on Avalanche can pay directly without bridging assets or changing wallets. This is particularly relevant for merchants serving emerging markets, gaming audiences, or DeFi-native customers whose on-chain assets are distributed across many ecosystems.

From a conversion rate standpoint, every chain you do not support is a potential abandoned checkout. Asking a customer to first bridge their Solana USDC to Ethereum before paying adds minutes of friction, wallet switching, and additional gas costs — most customers will leave rather than complete those steps.

Gas Fees: Who Pays and Why It Matters

Gas fees are the on-chain transaction costs required to process a payment on a proof-of-work or proof-of-stake blockchain. On Ethereum mainnet, gas fees have historically ranged from under $1 during quiet periods to $30–$80 during high congestion. Polygon and Base have cheaper gas, but the cost is still real and variable.

With Coinbase Commerce, the customer pays gas on top of the invoice amount. This creates three problems. First, the customer experience is unpredictable: a £50 checkout may effectively cost the customer £53 depending on when they pay. Second, at low purchase values — say, a £5 digital download — gas fees can exceed the product price entirely on Ethereum mainnet, making crypto payment economically irrational for the customer. Third, merchants setting exact invoice amounts cannot guarantee they will receive precisely that amount, since gas is deducted from wallet balances outside the payment contract logic in some wallet implementations.

SpacePay absorbs all gas fees as part of its infrastructure. The customer sees one number: the exact amount quoted in the checkout. The merchant receives the exact invoiced value minus the 1% processing fee. There are no surprises, no variable costs, and no abandoned checkouts caused by gas sticker shock.

Fiat Settlement: Same-Day Bank Transfer vs Manual Crypto Withdrawal

This is the most operationally significant difference between SpacePay and Coinbase Commerce for most businesses.

SpacePay automatically converts crypto payments to GBP, EUR, or USD at the time of transaction using real-time exchange rates and settles directly to the merchant's bank account the same business day. There is no manual intervention required. The merchant's accounts team sees a standard bank credit, indistinguishable in timing and format from a card payment settlement.

Coinbase Commerce does not offer automatic fiat settlement. Payments are received in crypto to a Coinbase account. To access fiat, a merchant must: (1) log into Coinbase, (2) sell the crypto for fiat on the spot market at Coinbase's conversion spread, (3) wait for the balance to settle, and (4) initiate a bank withdrawal which takes 1–3 business days via ACH in the US or longer for SWIFT/SEPA transfers. For UK merchants using Faster Payments, this process typically takes 2–4 days end-to-end.

Beyond the time cost, holding crypto between payment receipt and fiat conversion introduces exchange rate risk. A merchant who receives $10,000 in ETH on Monday and converts on Wednesday may receive $9,400 or $10,700 depending on ETH price movement. For businesses operating on thin margins or that price products in fiat, this volatility is a genuine financial risk.

White-Label Checkout: Your Brand vs Coinbase's Brand

When a customer reaches checkout using Coinbase Commerce, they see Coinbase's branding, colour scheme, and interface. There is no option to customise the checkout to match a merchant's own brand identity. For many merchants this is an acceptable trade-off — Coinbase's brand conveys trust and familiarity to crypto-native users.

For other businesses — luxury retailers, B2B SaaS platforms, marketplaces, and premium consumer brands — having a competitor's logo appear at the most critical moment of the purchase journey is unacceptable. These merchants need the checkout to feel like a seamless part of their own product.

SpacePay offers fully white-labelled checkout. Merchants can apply their own logo, brand colours, and custom domain. The customer experience is entirely within the merchant's brand environment. For SaaS platforms and marketplaces that embed SpacePay's payment widget, customers may not be aware they are using SpacePay infrastructure at all. This is the standard expected for any modern embedded payment solution.

Exchange Rate Locking: Real-Time Guarantees vs Limited Windows

In any crypto payment, there is a window between when the customer sees the invoice price and when the transaction is confirmed on-chain. During this window, crypto prices can move. Without a proper rate lock, either the merchant absorbs the shortfall if prices rise or the customer overpays if prices fall — neither outcome is acceptable.

SpacePay locks exchange rates in real time at checkout generation. The quoted crypto amount is guaranteed for the duration of the payment window. Merchants receive exactly the fiat amount invoiced regardless of price movement during checkout.

Coinbase Commerce provides a rate lock window but its implementation has been reported by merchants to have limited reliability, particularly during high volatility periods. Because settlement is in crypto rather than fiat, the rate lock matters less for the immediate transaction — but it matters significantly when merchants eventually convert, as they bear the full market risk between payment receipt and manual sale.

Webhooks and REST API: Developer Experience

Both SpacePay and Coinbase Commerce offer REST APIs and webhook notifications for payment events. The developer experience differs in reliability and flexibility.

SpacePay's webhook infrastructure is designed to guarantee delivery with automatic retries and exponential backoff. Merchants can configure multiple webhook endpoints, filter events by type, and inspect delivery logs. The REST API supports idempotent payment creation, which is critical for e-commerce integrations where network timeouts can cause duplicate order attempts. For a deep dive into reliable webhook design, see our guide on webhook payment notifications.

Coinbase Commerce's API is functional and well-documented. However, merchants on developer forums and Coinbase's own support channels have raised concerns about webhook delivery delays and missed events during peak load periods. For merchants running automated fulfilment pipelines where payment confirmation triggers downstream actions — digital licence delivery, SaaS account provisioning, logistics dispatch — unreliable webhooks translate directly into operational failures and customer complaints.

SpacePay's integration can typically be completed in under 30 minutes for standard e-commerce platforms. See our SDK integration guide for a step-by-step walkthrough.

Compliance: UK/EU Regulatory Focus vs US-Centric Infrastructure

Regulatory compliance is increasingly important for any business accepting crypto payments, particularly in the UK and EU where MiCA (Markets in Crypto-Assets Regulation) came into force and FCA oversight of crypto asset businesses continues to expand.

SpacePay is built with UK and EU compliance as a first-order concern. The product is MiCA-aligned, designed to meet FCA registration requirements, and includes compliance tooling appropriate for regulated sectors including travel, SaaS, luxury, iGaming, and fintech. Merchants in these verticals can use SpacePay with confidence that the payment infrastructure is designed for the regulatory environment they operate in.

Coinbase Commerce is designed around Coinbase's US regulatory framework and entity structure. It is available to merchants outside the US but its compliance documentation, support resources, and infrastructure are built for the US market. UK and EU merchants using Coinbase Commerce must independently assess whether its use is compatible with their own compliance obligations — a non-trivial exercise in a rapidly evolving regulatory landscape.

For a detailed overview of the current crypto payment regulatory landscape in key markets, see our MiCA compliance guide for merchants.
