Stablecoin comparison
USDC, USDT, EURC, and DAI compared on what matters when you accept payments — issuer, reserves, transparency, and use case. For merchants, reserve quality and attestations usually matter more than market cap.
| USDC | USDT | EURC | DAI | |
|---|---|---|---|---|
| Issuer | Circle (US-regulated) | Tether (offshore) | Circle | Sky / MakerDAO (decentralised) |
| Peg | US dollar | US dollar | Euro | US dollar |
| Backing | Cash + short-dated US Treasuries | Mixed reserves | Cash + euro reserves | Crypto collateral + RWAs |
| Attestations | Monthly, third-party | Quarterly | Monthly, third-party | On-chain, transparent |
| Model | Centralised, fiat-backed | Centralised, fiat-backed | Centralised, fiat-backed | Decentralised, over-collateralised |
| Best for | US/EU payments & compliance | Global liquidity & exchanges | Euro-denominated payments | DeFi-native, censorship-resistant |
Frequently asked questions
Which stablecoin is best to accept for payments?
For US and EU merchants, USDC is the common default: monthly third-party attestations, cash and short-dated Treasury reserves, and a regulation-forward issuer. USDT has the deepest global liquidity; EURC suits euro pricing; DAI is decentralised. Furlpay settles USDC on Arbitrum.
What is the difference between USDC and USDT?
Both are dollar-pegged, but USDC (Circle) publishes monthly third-party attestations and holds cash plus short-dated US Treasuries under a US-regulated issuer, while USDT (Tether) has the largest global liquidity but less granular reserve disclosure. For compliance-sensitive payments, USDC is usually preferred.
Does the blockchain matter as much as the stablecoin?
Yes — arguably more for cost. The same USDC costs over a dollar to move on Ethereum mainnet but a fraction of a cent on Arbitrum. The network you settle on drives your per-transaction cost, which is why Furlpay uses Arbitrum.
