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.
​

In March 2026, Mastercard agreed to acquire BVNK for up to $1.8 billion, with the deal closing announcement published 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 in 2024) 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 focuses on cross-border B2B payouts to emerging markets, with T+0 to T+1 settlement and an FX-plus-payout-fee pricing model. It fills the corridor gap for teams that need to pay suppliers in Africa, LATAM, or Southeast Asia and want stablecoin funding at the top of the flow.
​

Merge combines real named EUR, GBP, and USD IBANs with USDC and USDT settlement, licensed as an EMI under ACPR in France with VASP registration under AMF. That regulated wrapper matters when you need bank-grade named accounts for customer 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 supports EURC alongside USDC and USDT and issues named EUR IBANs under an ACPR EMI license. BVNK also supports EUR corridors on its enterprise plan.

Feature and pricing claims verified against each vendor's own product pages and third-party comparisons in August 2026. 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.
