Most comparisons of stablecoin payment platforms are lists of logos. That tells you nothing about whether a platform will hold your funds hostage, cover your corridors, or quietly route you through a currency you didn't ask for. Four questions matter more than any feature list.
Ask them in this order, because each one gates the next.
Custody First, Then Everything Else
Does the platform hold your funds, or does a licensed institution hold them while the platform only routes? A platform that custodies funds is structurally positioned to compete with the businesses that use it — it has your money and an incentive to do things with it. A non-custodial model routes settlement but never touches the funds; licensed partners hold the money, the platform provides quoting, conversion, and routing software only. That's a structural difference, not a policy promise.
Pair Depth and Rail Coverage
Next: how many corridors are actually direct, versus routed through an intermediate currency you'll pay for twice? And does the platform reach the rails your counterparties already use — SEPA, SEPA Instant, SWIFT, Faster Payments, local schemes — or does it strand you on-chain? Modality's answer: non-custodial by structure, 630 direct pairs across 36 currencies, 63 countries, settlement via RLUSD, USDC, and USDT on rails running 24/7. Evaluate any platform on custody model and pair depth before you look at anything else — the rest is detail.

FAQ: Best Stablecoin Payment Platform
What should the best stablecoin payment platform for B2B offer?
Direct currency-pair conversion instead of a forced USD leg, a non-custodial structure so the platform can't compete with its own customers, and 24/7 settlement -- not just "accepts stablecoin" as a checkbox.
What differentiates top stablecoin payment providers from each other?
The real differences are custody model (does the provider hold your funds or a licensed partner) and currency-pair depth (direct conversion vs. forced USD routing) -- not which stablecoins or chains they list.
How do B2B stablecoin payments work end to end?
A business gets a quoted rate, converts and settles directly across one of 630 currency pairs, and the receiving side gets local currency -- non-custodially, since licensed partners hold the funds, not Modality.
