Stablecoin payment processors are providers that accept and route stablecoin transactions on behalf of merchants, marketplaces, and B2B platforms, then settle the value to fiat or hold the balance. Choosing among them comes down to four levers: which chains and tokens they support, what they charge, how quickly they settle to fiat, and what compliance posture they offer for the markets a business serves. This piece compares the active processors handling production stablecoin payment volume in 2026.
​

Stablecoin payment processing has grown from a niche service into a category with real revenue. Bridge.xyz processed over $5 billion in annual volume before Stripe acquired it for $1.1 billion in October 2024. BVNK reported $10 billion in annualized transaction volume at its Series B. Coinbase Commerce and BitPay together handle hundreds of millions in monthly merchant volume according to issuer reports, with Helio adding Solana-native flows. The market is real, but the providers are not interchangeable.
​

A stablecoin payment processor sits between a payer and a recipient, accepting stablecoin transactions and either passing them through or converting them to fiat for settlement. The processor handles wallet generation, transaction monitoring, blockchain selection, and the off-ramp to a bank account. For B2B and cross-border use cases, the processor also handles compliance: KYC on the customer, KYB on the merchant, Travel Rule reporting for transfers above $1,000, and sanctions screening.
​

The architecture differs from traditional card processing. There is no acquirer-issuer split, no chargeback window, and no card network. Instead, the processor manages: a stablecoin receipt address per merchant or per invoice, monitoring of the relevant blockchains for incoming transfers, and a settlement engine that either holds the stablecoin balance or converts it to USD, EUR, or another fiat currency at a quoted rate. The internal coverage of stablecoin payment gateways by use case walks through the architecture in more detail.
​

Pricing models split into three patterns. Flat percentage fees of 0.5% to 1.5% on the transaction value, common for merchant acceptance. Per-transfer flat fees of $0.50 to $5, common for B2B payments. Spread on the fiat conversion, where the processor takes the bid-ask gap on the off-ramp. Most processors mix the three.
​

Six dimensions matter when evaluating a processor for a specific use case.
​

Supported tokens and chains. A processor that only supports USDC on Ethereum is not useful for a Mexican merchant whose customers hold USDT on Tron. The largest processors support 5 to 10 stablecoins across 8 to 15 chains.
​

Settlement currencies and speed. Some processors settle to USD only, some support 30+ fiat currencies. Same-day fiat settlement requires the processor to hold pre-funded liquidity at local banks; T+1 or T+2 is more common.
​

Geographic coverage. A processor licensed in the EU under MiCA and in the US under state money transmitter licenses can serve a transatlantic merchant base, with additional licenses in Singapore (PSA) and the UAE (VARA) extending APAC and Middle East coverage. Single-jurisdiction processors restrict the merchant's geographic reach.
​

Compliance and Travel Rule. B2B processors integrate Notabene or Sumsub for KYC and Travel Rule, with Veriff also common for identity verification. Sanctions screening through Chainalysis or TRM Labs is table stakes.
​

Fees and spread. Compare effective all-in cost: percentage fee plus per-transfer fee plus FX spread plus any monthly platform fees. The published rate card rarely tells the full story.
​

API surface and reliability. Webhook delivery, retry semantics, idempotency keys, and uptime SLAs matter for production integrations. The internal piece on stablecoin webhook infrastructure covers the API reliability dimension.
​

The following processors are the most active in production volume as of April 2026. Each entry focuses on the use case where the processor is strongest, not a generic feature dump.
​

Bridge focuses on B2B and developer-platform integrations. Acquired by Stripe in October 2024 for $1.1 billion, it serves payment platforms that want to embed stablecoin rails without building their own treasury and compliance stack. Bridge supports USDC and USDT alongside PYUSD across Ethereum, Solana, Base, Polygon, Arbitrum, Avalanche, Optimism, and Stellar. Settlement to 30+ fiat currencies, including XOF and other African corridors. Strong for developer platforms and fintech infra; less common for direct merchant acceptance.
​

BVNK serves enterprise B2B and cross-border treasury teams. It reported $10 billion in annualized transaction volume at its 2024 Series B, valued at $750 million. BVNK supports USDC, USDT, EURC, and PYUSD across 8 chains and offers same-day settlement in 30+ currencies including GBP, EUR, USD, and SGD. Travel Rule integration via Notabene. Common pick for crypto-native fintechs and remittance platforms moving regular B2B flows.
​

Conduit specializes in cross-border B2B for emerging markets. The platform routes USD-denominated stablecoin payments into local fiat across LATAM (Mexico, Colombia, Brazil) plus APAC (Philippines, Vietnam) and African corridors. Pricing typically beats SWIFT by 90% on $10K to $100K transfers. Conduit routes for SaaS exporters and B2B platforms paying suppliers in LATAM and APAC.
​

Coinbase Commerce powers merchant acceptance for online stores. Shopify enabled USDC on Base through Coinbase Commerce in 2024, giving any Shopify merchant the option to accept stablecoin payments. Fees are 1% on stablecoin transactions, with USDC-on-Base prioritized for the lowest gas. Settlement to a Coinbase account is instant; off-ramp to bank takes 1 to 3 days. Best for ecommerce merchants who already use Shopify, BigCommerce, or WooCommerce.
​

BitPay is the longest-running crypto payment processor, founded in 2011. It supports BTC, ETH, USDC, USDT, GUSD, BUSD, DOGE, LTC, and others across multiple chains. BitPay charges 1% on transactions and offers settlement in USD, EUR, GBP, CAD, AUD, and others. Used by Newegg and AT&T alongside luxury retailers, with Microsoft historically among the largest integrators. BitPay's compliance posture is mature given the company's age, which makes it the default for regulated retailers entering the category.
​

Helio focuses on Solana-native merchant acceptance and creator monetization. It supports USDC and USDT alongside SOL, BONK, and other SPL tokens. Fees are 0.75%, lower than ETH-based competitors due to Solana's negligible gas. Strong fit for creators selling digital goods, NFT projects, and Solana-native merchants. Helio handles 0.5% of US-Solana merchant volume according to issuer reports.
​

These two are primarily on-ramps and off-ramps but serve as embedded stablecoin payment infrastructure for wallets and apps. MoonPay processes over $5 billion annually with coverage in 160+ countries. Transak supports 145+ countries with 100+ payment methods. Both are commonly embedded as the fiat boundary in larger payment flows rather than used as standalone merchant processors.
​

Circle, the issuer of USDC, runs Circle Payments Network as a settlement service for licensed institutions. Mint allows direct USDC issuance and redemption against bank deposits. Best for institutions that want a direct relationship with the issuer rather than going through a third-party processor. Used by remittance companies and neobanks alongside licensed payment institutions.
​

Following the Bridge acquisition, Stripe rolled stablecoin payments into its core product. Merchants on Stripe can accept USDC payments with the same integration they use for cards. Settlement to fiat is automatic. Stripe's geographic and merchant reach is the largest of any processor in this list, but the integration is newer and less feature-rich than purpose-built processors. Pricing is 1.5% per transaction, no card-network interchange.
​

The right processor depends on the use case more than the feature list.
​

For online merchants on Shopify or another major platform: Coinbase Commerce or Stripe Crypto, since both integrate without engineering effort. For B2B SaaS exporters paying suppliers in emerging markets: Conduit or BVNK, since they offer the FX corridors and per-transaction economics that fit large recurring transfers. For developer platforms embedding stablecoin payments: Bridge, since it has the most flexible API and the deepest geographic licensing. For Solana-native businesses: Helio. For remittance and consumer flows: MoonPay or Transak as the fiat boundary, with a custodian or wallet provider on the back end.
​

Multi-chain coverage matters most when the merchant's customers hold balances on different chains. A processor that supports only Ethereum will reject 70% of stablecoin volume, since USDC volume on Solana and Base (plus Arbitrum) together exceeds Ethereum mainnet volume per DeFiLlama. The orchestration challenge of accepting payments across chains and settling to a single accounting unit is covered in the multi-chain treasury piece.
​

The integration shape varies by processor and use case. The simplest pattern is hosted checkout: the merchant redirects the buyer to a processor-hosted page that handles wallet connection and the payment flow. Coinbase Commerce and Helio offer this model with under an hour of integration work. The next tier is API-only: the merchant generates payment intents server-side and constructs its own checkout UI. Stripe Crypto and Bridge use this pattern. The deepest tier is multi-chain payment routing, where the merchant exposes its own wallet UX and the processor only handles the chain abstraction and offramp. BVNK and Circle Web3 Services support this pattern for fintechs and payment platforms building branded experiences.
​

Webhook reliability is the primary operational concern at scale. Stablecoin transactions are finalized onchain, but webhook delivery to the merchant is not. Production processors implement HMAC-signed payloads and retry policies of 3 to 7 attempts with exponential backoff, plus a polling fallback for environments where webhooks are difficult. The internal coverage of stablecoin webhook infrastructure covers reliability patterns in detail.
​

Custody choice follows from the integration depth. Hosted-checkout merchants do not hold any stablecoin balance; the processor settles to fiat automatically. API-only merchants typically hold a transient balance that the processor sweeps to fiat on a configurable schedule. Multi-chain payment platforms hold ongoing operational balances and need qualified custody from Anchorage Digital or Fireblocks for institutional posture. The decision affects insurance coverage, accounting treatment, and counterparty risk exposure.
​

Reconciliation is the under-discussed operational concern. Each processor exposes its own transaction format, settlement currency, and reporting cadence. Finance teams running multiple processors typically build a normalization layer that maps each processor's events into the team's accounting system, then reconciles processor-reported settlements against bank deposits weekly. Platforms running stablecoin volume across 5+ processors usually invest in a treasury operations tool such as Chainalysis Compass or an in-house dashboard.
​

Eco operates one layer below most of these processors as the stablecoin orchestration network. A processor like BVNK or Bridge can integrate Eco to handle the cross-chain routing layer rather than building per-rail integrations to CCTP, Hyperlane, and LayerZero independently. Routes (CLI plus API) selects the path per transfer based on cost and finality, returning a single API surface to the processor. For payment platforms evaluating whether to build cross-chain in-house or integrate an orchestration layer, the intent protocols breakdown compares the orchestration options.
​

Helio at 0.75% on Solana-native flows is the lowest published rate. For multi-chain merchant acceptance, Coinbase Commerce and BitPay both charge 1%. B2B processors typically use spread plus per-transfer fees rather than percentage fees, so all-in cost depends on transfer size and corridor.
​

BVNK, Bridge, Conduit, and Circle all integrate Travel Rule providers (typically Notabene or Sumsub) for transfers above $1,000. Coinbase Commerce and BitPay handle it for merchant flows where the merchant is the regulated counterparty. Helio routes Travel Rule through its institutional partners for transfers above the threshold.
​

Yes. Most major processors offer settlement in USD, EUR, GBP, and a list of secondary currencies. BVNK and Conduit support 30+ fiat settlement currencies. Coinbase Commerce settles to USD by default with conversion options for major currencies. Same-day settlement requires pre-funded liquidity, so smaller currencies typically settle T+1 or T+2.
​

No. Stablecoin transfers are final once confirmed onchain. Processors offer dispute support and merchant protection programs in some cases, but there is no equivalent to card chargebacks. This is a feature for merchants but a risk for buyers, which is why processor-mediated dispute mechanisms are increasingly common for consumer flows.
​

B2B processors prioritize cross-border transfers, FX corridors, and Travel Rule compliance for transfers $1,000 and above. Merchant processors prioritize ecommerce checkout integration, low per-transaction fees, and consumer-flow user experience. Bridge, BVNK, and Conduit are B2B-first; Coinbase Commerce, BitPay, Helio, and Stripe Crypto are merchant-first.
