The stablecoin payments and infrastructure market

Stablecoin Payments & Infrastructure: Market Map

1) Thesis

Stablecoins are unbundling the correspondent banking stack, and value is migrating from the issuers (whose float economics get competed away) to the orchestration and on/off-ramp layers that own the merchant, enterprise, and last-mile fiat relationships.

2) Segments

A. Issuers / Reserve Managers

• Circle (USDC), Tether (USDT), Paxos (USDP, white-label for PayPal's PYUSD), First Digital (FDUSD), Agora, Ethena (USDe is a synthetic dollar — arguably adjacent rather than a true stablecoin)
• Dynamics: High-margin float businesses (T-bill yield) facing compression as regulation (GENIUS Act, MiCA), white-label issuance, and yield-sharing turn issuance into a commodity. Tether's emerging-market distribution moat is the exception.

B. Orchestration / Stablecoin APIs ("stablecoin-as-a-service")

• Bridge (acquired by Stripe), BVNK, Zero Hash, Fireblocks (payments product), Conduit, Brale
• Dynamics: The hottest M&A layer — Stripe paying ~$1.1B for Bridge signaled that abstraction layers (issue, convert, move stablecoins via API) are the strategic choke point. Rapid commoditization risk from incumbents building in-house.

C. On/Off-Ramps & Last-Mile Fiat Liquidity

• MoonPay, Ramp Network, Transak, Yellow Card (Africa), Bitso (LatAm), Onafriq (less sure on depth of their stablecoin rails specifically)
• Dynamics: Grinding, jurisdiction-by-jurisdiction licensing and banking work; defensible where local liquidity is scarce (Africa, LatAm), thin-margin and commoditized in G10 corridors.

D. Cross-Border B2B Payments & Remittances

• Airwallex (stablecoin usage less certain), Sling Money, Félix Pago, Conduit, Huma Finance (PayFi liquidity), Arf
• Dynamics: The clearest real-world PMF — replacing SWIFT/correspondent pre-funding for SME treasury and remittances; wins on working-capital release, not just fees.

E. Settlement Rails, Cards & Merchant Acceptance

• Visa & Mastercard (USDC settlement pilots), Stripe, Checkout.com, Rain (stablecoin-linked cards), Baanx, Shopify (USDC via Base/Stripe)
• Dynamics: Incumbents co-opting stablecoins to defend interchange; card-issuing startups arbitrage the gap between crypto balances and fiat acceptance.

3) Where value accrues

Segment B (orchestration), with Segment A retaining absolute dollars. Issuers capture the largest current profit pool (Tether's reported ~$13B 2024 profit), but that's rate-dependent and being regulated/competed toward zero-margin utility. Orchestration wins the durable value: it owns the enterprise integration, abstracts issuer choice (making issuers interchangeable suppliers), and sits on every transaction regardless of which stablecoin or chain wins. Stripe/Bridge is the template.

4) White space

1. Stablecoin-native treasury & FX risk management for corporates: No player offers a full CFO suite — multi-stablecoin/multi-chain cash management, automated sweeps between yield-bearing and payment stablecoins, hedging of local-currency stablecoin exposure (cNGN, BRZ-type assets), and audit-grade accounting/ERP integration. Everyone does movement; nobody does management.
2. Interoperable compliance/messaging layer (the "SWIFT MT layer" for stablecoins): Travel-rule data, sanctions screening, and rich remittance metadata (invoices, purpose codes) attached to stablecoin transfers across chains and issuers. Chainalysis/TRM do forensics after the fact; no one provides standardized pre-transaction compliance messaging that banks would require to fully adopt stablecoin settlement.

Confidence notes: Company product specifics in Segments C–E move fast; Airwallex and Onafriq stablecoin depth flagged above. Tether profit figure is company-reported, not independently audited.
