Crypto & stablecoin checkout
USDC and USDT acceptance integrated into the same checkout flow as cards, not a separate awkward crypto page.
Development · E-commerce
Commerce built for conversion, not just a crypto-accept badge. Stablecoin checkout, multi-chain acceptance and platform engineering wired into the same flow customers already trust.
Corum8 builds e-commerce platforms and crypto-native checkout integrations — stablecoin payment acceptance, multi-chain checkout, Shopify and WooCommerce plugin development, headless commerce architecture and the fraud, subscription and analytics tooling real commerce operations need. $300M+ cumulative volume across our payment builds, engineered for conversion, not just crypto novelty.
What's included
USDC and USDT acceptance integrated into the same checkout flow as cards, not a separate awkward crypto page.
Native Shopify, WooCommerce and Magento integrations that merchants can actually install and configure.
Ethereum L2s, Solana and Tron routed by customer wallet and cost, without merchant-facing complexity.
Order state synced cleanly across payment methods, so crypto orders don't live in a separate broken system.
Composable storefronts on Next.js or Astro backed by a commerce API, for merchants outgrowing platform templates.
Recurring stablecoin billing that handles the wallet-approval and balance realities crypto payments add.
Risk scoring built for crypto's finality — the fraud patterns differ from card-network chargebacks entirely.
Funnel and checkout analytics that show where crypto-payment customers actually drop off.
Is this you?
You don't need all of them. One is usually enough to justify the call.
You're losing sales to customers who want to pay in stablecoins and currently can't.
Shopify's native crypto options don't cover the chains or stablecoins your customer base actually uses.
Your fraud system was built for card chargebacks and isn't catching the patterns specific to crypto payments.
Shopify or WooCommerce templates are constraining a storefront experience you need to build custom.
Recurring billing works fine for cards but crypto subscribers are churning on failed wallet approvals.
You're entering markets where stablecoin rails would outperform your current payment options.
Sectors
The platform differs, the conversion discipline doesn't.
Native plugin integrations merchants can install directly.
Stablecoin acceptance routed across the chains your customers actually hold.
Token-gated product access and member-only storefront experiences.
Composable storefronts for merchants who've outgrown platform templates.
Stablecoin-native recurring billing built for wallet-approval realities.
Multi-vendor settlement and payout infrastructure at scale.
Points and rewards programs with real on-chain redemption value.
Stablecoin rails cutting cross-border payment friction and fees.
Process
Where customers currently drop off, and which payment methods and corridors actually need support.
Checkout, plugin and multi-chain acceptance engineered against the funnel audit.
Chargeback-adjacent fraud patterns, failed wallet approvals and subscription edge cases tested before launch.
Analytics live from day one, with iteration on the specific steps where crypto customers are dropping off.
Case studies
A DTC brand's crypto checkout and a multi-vendor marketplace's payout rebuild.
A direct-to-consumer brand wanted stablecoin checkout without risking the conversion rate on its existing card-payment flow. Integrating USDC acceptance directly into the existing checkout UI, rather than a separate crypto page, added a new payment option with zero measurable impact on overall conversion.
A multi-vendor marketplace was settling vendor payouts through slow weekly bank batches that frustrated sellers. Rebuilding settlement on stablecoin rails moved vendor payouts to near-instant, becoming a differentiator the marketplace used directly in seller acquisition.
Why Corum8
Checkout integration built to convert customers, not just to display a crypto-accept badge.
Native Shopify and WooCommerce plugins merchants can install, not a custom fork nobody can maintain.
Risk scoring that understands crypto finality, not a card-network fraud system stretched to fit.
Payment engineering discipline proven across our broader payments practice, applied to commerce specifically.
Composable commerce architecture for merchants who've outgrown template-based platforms.
Checkout funnel analytics that show exactly where crypto-payment customers drop off.
What drives scope
Cost is driven by platform choice, payment method breadth and fraud tooling depth.
A Shopify plugin is lightest. Headless commerce architecture on a custom stack is a materially bigger build.
Single-stablecoin, single-chain acceptance is simple. Multi-chain, multi-stablecoin acceptance multiplies integration work.
Basic risk scoring is baseline. Real-time behavioral fraud detection tuned to crypto patterns is a bigger system.
One-time purchases are simplest. Recurring stablecoin billing with wallet-approval handling adds real scope.
Single-market commerce is lighter than multi-region storefronts with localised payment methods and per-market content.
A single-vendor store is simplest. Multi-vendor marketplaces need settlement and payout infrastructure of their own.
FAQ
Crypto-native e-commerce development is the engineering of checkout, platform and commerce infrastructure that accepts stablecoin and multi-chain payments as first-class payment methods, integrated into the same conversion-optimized flow as cards. The work spans plugin development for platforms like Shopify and WooCommerce, headless commerce architecture, fraud tooling and subscription billing built for crypto's specific realities.
Cost is driven by platform choice, payment method breadth, fraud tooling depth, subscription complexity, multi-region scope and marketplace complexity. A single-stablecoin Shopify plugin is a different budget than a headless multi-vendor marketplace with multi-chain acceptance and custom fraud scoring.
Yes — native plugin integration is one of the most common engagements, adding stablecoin checkout directly into your existing checkout flow rather than a separate crypto page. The goal is checkout that converts, not a bolt-on feature customers have to hunt for.
Through risk scoring built for crypto's actual failure modes — since crypto settlement is final, there's no card-network chargeback mechanism, so fraud prevention has to happen before the transaction confirms, not after. This means different tooling than a standard card-fraud stack, tuned to wallet behavior and transaction patterns specific to crypto.
Checkout integration, platform plugin development or headless architecture, multi-chain payment routing, order management sync, fraud and risk scoring, subscription billing where relevant, and conversion analytics. Product catalog design and merchandising strategy typically stay with your existing team.
Yes — for merchants who've outgrown platform templates, we build composable storefronts on Next.js or Astro backed by a commerce API, giving full control over the customer experience. Headless makes sense once template constraints are actively limiting conversion or brand expression, not as a default starting point.
Yes — multi-vendor marketplaces need settlement and payout infrastructure of their own, and stablecoin rails can move vendor payouts from slow bank batches to near-instant settlement. This is a meaningfully bigger engineering scope than single-vendor checkout, given the reconciliation and payout logic involved.
Custom earns its place once your volume, catalogue or payment logic genuinely outgrows what a platform will do. Unusual settlement flows, multi-region payment routing, deep ERP integration and marketplace mechanics are the usual triggers. Below that, an existing platform gets you selling sooner and we will say so. Plenty of our e-commerce work is actually extending a platform rather than replacing it, which gives you the custom behaviour where it matters and keeps the parts that already work. We scope against your actual volumes, not a template.
