The 4 vendors · per-vendor use-case shape

Each vendor wins a different scenario. The matchmaker quiz scores all 4 against your specific situation; below is the use-case map for context.

USDC (Circle) — Best for US-regulated businesses · highest compliance posture

Best for: US-regulated issuer (Circle) · monthly attestations · best for B2B + enterprise customers · multi-chain (Ethereum, Solana, Avalanche, Base) · strong banking partnerships

Trade-offs: Circle has frozen wallets historically (Tornado Cash incident) · slightly higher integration cost · less liquid than USDT in some markets

USDT (Tether) — Best for international / high-liquidity use cases · widest exchange support

Best for: Most liquid stablecoin globally · widest exchange support · works in markets where US-regulated stables don't · TRC-20 (Tron) version has very low fees

Trade-offs: Less regulatory clarity than USDC · Tether transparency has been historically questioned · lower B2B / enterprise acceptance · regulatory risk in some jurisdictions

PYUSD (PayPal) — Best for PayPal-ecosystem businesses · consumer-facing UX

Best for: Backed by PayPal (massive consumer reach) · works inside PayPal/Venmo wallets · consumer-friendly UX · NY-regulated (Paxos issuer)

Trade-offs: Newer (less liquidity) · primarily Ethereum/Solana · less B2B traction · ecosystem still developing

DIY routing (multi-stable) — When you need to support multiple stables based on customer choice

Best for: Customer chooses their preferred stable · no single-issuer risk · supports international + US use cases simultaneously · flexible

Trade-offs: Engineering complexity (multi-chain abstraction) · reconciliation across stables · regulatory burden compounds · operational overhead
