Airwallex is a strong global-business payment platform, covering more than 150 countries with local rails in about 50, but its stablecoin settlement layer is limited compared to purpose-built providers. Teams that want to move USDC or USDT natively across chains, and only cash in and out of fiat at the edges, will get a different cost curve from a stablecoin-native platform.
​

This article covers where Airwallex fits, why finance teams look for alternatives when the workload is stablecoin-heavy, and how five providers (Eco, BVNK, Bridge, Conduit, Merge) compare on the criteria that actually matter: chain coverage, supported tokens, pricing model, and settlement guarantees.
​

Stablecoin cross-border payments infrastructure is the API layer that lets a business hold, receive, and send USD-pegged tokens (USDC, USDT, PYUSD, EURC) as the settlement medium for international B2B flows, with fiat rails touched only at the customer edge. Unlike a fiat-first platform, the working balance stays onchain, so treasury sees one denomination across corridors and settlement is measured in seconds rather than days.
​

The category overlaps with, but is distinct from, fiat cross-border APIs and consumer remittance apps. The definition that matters for platform buyers: a stablecoin-native provider prices, routes, and settles in a stablecoin as first class, and exposes fiat on- and off-ramps as optional edges. See Circle's stablecoin primer for the underlying token model.
​

Airwallex is a fiat-native platform. Its coverage in 150+ countries runs through SWIFT plus direct connections to local rails like SEPA, FPS, and NPP, and its FX model uses a percentage markup plus per-transaction fees negotiated by volume, per Routefusion's 2026 comparison.
​

For a company whose primary payment flow is USDC in and local fiat out, that fiat-first architecture is inverted. The stablecoin sits inside a fiat wrapper rather than being the settlement medium. A stablecoin-native provider treats USDC or USDT as the working balance and only touches fiat rails at the customer edge.
​

Eco is a cross-chain stablecoin orchestration platform: a single API accepts any major stablecoin on any major chain, prices the route up front, and delivers the destination stablecoin with sub-minute finality. Where Airwallex prices FX as a spread after the fact, Eco quotes the destination amount before the sender signs, which lets a platform pass a guaranteed price to its own customer without carrying spread risk.
​

Best fit: B2B platforms, marketplaces, and payroll providers whose flows cross multiple stablecoins and multiple chains, and who want one integration to cover the whole surface. See the B2B infrastructure comparison for how Eco stacks against the rest of the stablecoin-native field.
​

BVNK covers 130-plus markets and supports USDC, USDT, PYUSD, and other tokens across major chains, with named virtual accounts, custody, and payment orchestration. It requires a minimum of $500,000 per month in processed payments and at least six months of trading history, per BVNK, which sets it firmly in the enterprise segment.
​

Mastercard announced a definitive agreement to acquire BVNK on March 17, 2026, for up to $1.8 billion including $300 million in contingent payments, and BVNK became part of Mastercard on August 3, 2026. That anchors BVNK inside a card-network stack, which raises the neutrality question if you're a card-network competitor. See BVNK alternatives for the full picture.
​

Bridge (acquired by Stripe, completed in February 2025) runs a payouts API optimized for dollar-denominated B2B disbursements, alongside its own Bridge USD stablecoin. Under Stripe, Bridge inherits Stripe's compliance and treasury layer, which makes it a natural pick if you are already inside the Stripe stack or want a single vendor for card and stablecoin flows.
​

Conduit runs named USD accounts and cross-border payouts for businesses in 100+ countries, routing across eight US banking partners plus Fedwire, FedNow, RTP, SWIFT, SEPA Instant, PIX and SPEI, with USDC, USDT and USDH on the stablecoin side. Conduit describes its payout pricing only as tiered by volume and publishes no rate card, so treat any quoted fee as something to confirm in your own contract. It fills the corridor gap for teams that need stablecoin funding at the top of the flow and local fiat at the end of it.
​

Merge combines multi-currency accounts in EUR, GBP, USD and 60+ currencies with stablecoin settlement across 100+ countries. Merge states that it holds payment and e-money licences across the jurisdictions it operates in and safeguards client funds in ring-fenced accounts at tier-1 banks; it does not name a specific regulator or licence number publicly, so confirm the perimeter that applies to your entity directly with Merge. The named sub-account model matters when you need customer fund segregation and cannot use pooled virtual accounts.
​

Match the provider to the shape of your flow, not to the marketing line. If your workload is mixed fiat and stablecoin with card and bank flows on both sides, Airwallex plus a stablecoin bolt-on can work. If the workload is stablecoin-in, stablecoin-out across chains, Eco is designed for exactly that surface. If it is stablecoin-in, local-fiat-out to specific corridors, Bridge or Conduit fits. If the buyer requires named IBANs, Merge or BVNK become the shortlist.
​

Airwallex is a fiat-first platform with card and local-rail coverage across 150+ countries; stablecoin settlement sits on top of that stack rather than being the core rail. Teams whose working balance is USDC or USDT usually pair Airwallex with a stablecoin-native provider or replace it outright.
​

Eco is purpose-built for multi-chain orchestration: one API accepts any major stablecoin on any major chain and quotes the destination amount before signing. BVNK is the enterprise pick for teams that need SLAs and named accounts, and Bridge fits Stripe-native stacks.
​

Merge runs euro accounts alongside its stablecoin rails and lists EUR among the 60+ currencies it supports. BVNK also supports EUR corridors. Neither publishes a per-token list tied to euro-denominated stablecoins, so confirm EURC support directly with the vendor.
​

Claims were re-checked against each vendor's own live site in September 2026. BVNK's $500,000 monthly minimum, six-month trading-history requirement and 130+ country coverage come from bvnk.com; the Mastercard deal terms come from Mastercard's investor release and BVNK's own closing post; the Stripe acquisition of Bridge comes from Stripe's newsroom; Conduit's rail list and Merge's currency coverage come from their homepages. None of the five providers publishes a public rate card, so the pricing column says what each vendor publicly describes and marks the rest as not published rather than estimating it. Chain and token counts reflect what each provider publicly documents; enterprise contracts may extend coverage. Recategorized as stablecoin-native only when the provider treats a stablecoin as the working balance, not as a wrapper around fiat rails.
