Picking a fiat-to-stablecoin onramp in 2026 comes down to four variables that move together: which regions a provider is licensed in, what they charge for card versus ACH or SEPA, which stablecoins they settle to which chains, and how cleanly they slot into your app. The eight providers below cover roughly 95% of consumer onramp volume globally. We pulled fees, KYC tiers, and integration models directly from each provider's pricing and developer pages in May 2026.
​

Wyre, which had been a major US ACH onramp, shut down in 2023 and is included here only as a reminder that onramp dependencies need a fallback. Most apps that ran on Wyre migrated to Stripe Crypto Onramp or aggregated through Onramper.
​

MoonPay is the most widely embedded consumer onramp, with licensing in 50 US states and ~160 countries. Card purchases run roughly 3.99% with a $3.99 minimum; ACH and SEPA settle around 1.99%, with limits that climb after enhanced KYC. Supported stablecoins include USDC, USDT, DAI, and PYUSD across Ethereum, Solana, Polygon, Base, Arbitrum, and Optimism.
​

Integration is widget-first (drop in via URL), with a JS SDK and fully hosted checkout for partners who do not want to ship custody UX. MoonPay's KYC ladder starts with a phone and email check for low limits, then graduates to ID + selfie for higher thresholds. Reference: moonpay.com/buy/fees.
​

Transak operates in 160+ countries, 49 US states (no Hawaii as of May 2026), and supports the widest set of local payment rails: UPI in India, PIX in Brazil, SEPA Instant in Europe, and ACH plus card in the US. Card fees range from 3.5% to 5.5% depending on region and issuer; SEPA is the cheapest at ~0.99%. Stablecoin coverage spans USDC, USDT, DAI, PYUSD, and EURC.
​

Transak has three KYC tiers and a developer-friendly widget with NFT checkout and on-ramp aggregation modes. The hosted version is common in self-custodial wallets. Reference: transak.com/pricing.
​

Ramp leans into Open Banking in the UK and EU, which lets it offer ~0.49% SEPA fees, the lowest of the major widget onramps. US ACH sits around 1.49% and card ~2.9%. Ramp covers 150+ countries and 47 US states, with stablecoin support for USDC, USDT, DAI, and EURC.
​

The KYC flow uses bank-account verification as a lighter alternative to ID upload in supported European countries, which materially reduces drop-off. Integration is SDK-first with hosted and in-wallet variants. Reference: ramp.network/buy.
​

Banxa is the regional specialist, particularly strong in Australia (POLi, PayID) and Canada (Interac). It supports 130+ countries with card fees around 2.99% to 3.99% and SEPA at ~1.99%. Stablecoin coverage focuses on USDC and USDT; legacy BUSD support is being deprecated.
​

For wallets and dApps targeting APAC users, Banxa often beats US-centric providers on conversion. Integration is widget plus hosted. Reference: banxa.com/fees.
​

Coinbase Onramp is a different product than Coinbase Pay or the Coinbase Wallet. It is a developer-facing onramp that lets apps embed Coinbase's KYC and payment rails directly. For users with an existing Coinbase account, ACH transfers are free; non-Coinbase users pay roughly 3.99% on Apple Pay or Google Pay.
​

Stablecoin support is USDC-first, with gas-free USDC transfers on Base. The integration is an embedded SDK with a CDP (Coinbase Developer Platform) account required. Reference: portal.cdp.coinbase.com/products/onramp.
​

Stripe's onramp is the lowest-fee mainstream option for US users at roughly 1.5% plus $0.30 per transaction. It reuses Stripe Identity for KYC, which is already deployed across millions of Stripe accounts, and settles USDC, USDT, ETH, and SOL on Ethereum, Solana, Base, and Polygon.
​

The catch is geographic coverage: Stripe Crypto Onramp is live in the US and 30+ countries, narrower than MoonPay or Transak. Integration is an embedded element similar to Stripe Elements for cards. Reference: stripe.com/use-cases/crypto.
​

Mercuryo is the EU-centric option, with strong SEPA Instant rails (~1.95%), card fees around 3.95%, and growing LatAm coverage. It supports USDC, USDT, and EURC and also issues crypto-funded debit cards in supported regions, which makes it a useful pairing for apps that want both an onramp and a spend rail.
​

Integration is widget plus SDK. Reference: mercuryo.io/fees.
​

Onramper does not run its own KYC or payment rails. Instead it aggregates 25+ providers (including all of the above) behind a single SDK, routing each user to the best-priced provider that is licensed in their region. For a global app, this typically beats single-provider integrations on both conversion and fees because Onramper falls back when one provider rejects a card.
​

The trade-off is less control over the user experience and a thin aggregator margin layered on top of provider fees. Reference: onramper.com/pricing.
​

For US-only consumer apps with mainstream users, Stripe Crypto Onramp wins on fees and KYC reuse. For global wallets, Onramper or Transak give the widest country coverage. For USDC-first apps building on Base, Coinbase Onramp's free ACH for Coinbase users is hard to beat. For EU-heavy products, Ramp's Open Banking flow has the lowest drop-off. If you only integrate one, MoonPay is the safest default because of its 160-country footprint and 50-state US licensing.
​

No. USDC and USDT are universal. PYUSD is supported by MoonPay and Transak. EURC is supported by Ramp, Transak, and Mercuryo. DAI is widely supported but declining as issuance shifts to USDS. Niche stablecoins (FRAX, crvUSD, GHO) generally require a DEX swap after onramping into USDC or USDT.
​

Onramps are only half the loop. For converting stablecoins back to fiat, see Best Stablecoin Offramps 2026. For spending stablecoins directly without offramping, see Best Stablecoin Debit Cards 2026. For the underlying mechanics of how stablecoins move between providers, see how stablecoin transfers settle onchain.
​

Fees, region counts, and KYC tier descriptions were pulled directly from each provider's public pricing or developer documentation pages in May 2026: moonpay.com/buy/fees, transak.com/pricing, ramp.network/buy, banxa.com/fees, portal.cdp.coinbase.com/products/onramp, stripe.com/use-cases/crypto, mercuryo.io/fees, and onramper.com/pricing. US state coverage reflects each provider's published licensing map; international country counts reflect their stated availability and may exclude OFAC-sanctioned jurisdictions. Card fees vary by issuer and country and the figures above reflect typical retail rates rather than negotiated partner rates.
