Development · E-commerce

We build commerce that actually converts.

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

Everything under “e-commerce development” that we actually run

Crypto & stablecoin checkout

USDC and USDT acceptance integrated into the same checkout flow as cards, not a separate awkward crypto page.

Platform plugin development

Native Shopify, WooCommerce and Magento integrations that merchants can actually install and configure.

Multi-chain payment acceptance

Ethereum L2s, Solana and Tron routed by customer wallet and cost, without merchant-facing complexity.

Inventory & order management

Order state synced cleanly across payment methods, so crypto orders don't live in a separate broken system.

Headless commerce architecture

Composable storefronts on Next.js or Astro backed by a commerce API, for merchants outgrowing platform templates.

Subscription & recurring billing

Recurring stablecoin billing that handles the wallet-approval and balance realities crypto payments add.

Fraud & chargeback prevention

Risk scoring built for crypto's finality — the fraud patterns differ from card-network chargebacks entirely.

Analytics & conversion optimization

Funnel and checkout analytics that show where crypto-payment customers actually drop off.

Is this you?

Signals you need serious e-commerce engineering

You don't need all of them. One is usually enough to justify the call.

Customers are asking for crypto checkout

You're losing sales to customers who want to pay in stablecoins and currently can't.

Your platform doesn't support the chains you need

Shopify's native crypto options don't cover the chains or stablecoins your customer base actually uses.

Fraud patterns don't match your current tooling

Your fraud system was built for card chargebacks and isn't catching the patterns specific to crypto payments.

You've outgrown platform templates

Shopify or WooCommerce templates are constraining a storefront experience you need to build custom.

Subscription billing is breaking on crypto

Recurring billing works fine for cards but crypto subscribers are churning on failed wallet approvals.

You're expanding into new payment corridors

You're entering markets where stablecoin rails would outperform your current payment options.

Process

How an e-commerce build runs, in practice

  1. 01

    Audit the checkout funnel

    Where customers currently drop off, and which payment methods and corridors actually need support.

  2. 02

    Build payment & platform integration

    Checkout, plugin and multi-chain acceptance engineered against the funnel audit.

  3. 03

    Test fraud and edge cases

    Chargeback-adjacent fraud patterns, failed wallet approvals and subscription edge cases tested before launch.

  4. 04

    Launch and optimize conversion

    Analytics live from day one, with iteration on the specific steps where crypto customers are dropping off.

Case studies

E-commerce work we've shipped

A DTC brand's crypto checkout and a multi-vendor marketplace's payout rebuild.

DTC Consumer Brand

Crypto checkout added without disrupting existing card conversion

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.

Multi-Vendor Marketplace

Vendor payout settlement moved from weekly batches to near-instant

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.

Real platform plugin engineering

Native Shopify and WooCommerce plugins merchants can install, not a custom fork nobody can maintain.

Fraud tooling built for crypto's realities

Risk scoring that understands crypto finality, not a card-network fraud system stretched to fit.

$300M+ in real payment volume experience

Payment engineering discipline proven across our broader payments practice, applied to commerce specifically.

Headless flexibility when platforms constrain

Composable commerce architecture for merchants who've outgrown template-based platforms.

Analytics tied to actual conversion

Checkout funnel analytics that show exactly where crypto-payment customers drop off.

What drives scope

What drives scope and budget on an e-commerce build

Cost is driven by platform choice, payment method breadth and fraud tooling depth.

Platform choice

A Shopify plugin is lightest. Headless commerce architecture on a custom stack is a materially bigger build.

Payment method breadth

Single-stablecoin, single-chain acceptance is simple. Multi-chain, multi-stablecoin acceptance multiplies integration work.

Fraud tooling depth

Basic risk scoring is baseline. Real-time behavioral fraud detection tuned to crypto patterns is a bigger system.

Subscription complexity

One-time purchases are simplest. Recurring stablecoin billing with wallet-approval handling adds real scope.

Multi-region scope

Single-market commerce is lighter than multi-region storefronts with localised payment methods and per-market content.

Marketplace complexity

A single-vendor store is simplest. Multi-vendor marketplaces need settlement and payout infrastructure of their own.

FAQ

Questions worth a direct answer

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.

  6. 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.

  7. 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.

  8. 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.
