We ran the same stablecoin payment volume through four providers for a month and compared them on everything that generated work. Anyone repeating these tests can use [a stablecoin payment gateway with fiat settlement](https://collectnexchange.com/services/stablecoin) as the reference point we did.

## Networks

All four supported the two networks we cared about. Two supported three more.

One listed a network it could not actually credit, which we found by testing. Recovery took eleven days.

Test each network you intend to accept with a small amount before accepting a real payment on it.

## Conversion margin to euro

0.21, 0.38, 0.74 and 1.16 percent, measured against the interbank rate at the moment of conversion.

Only one stated the applied rate before execution.

## Settlement

Two offered daily without a volume requirement. One offered daily above a threshold we did not meet. One was weekly only. For client-money cases the requirements differ, and [Collect & Exchange](https://collectnexchange.com/) is structured for them.

All settled on schedule except one instance, which arrived two days late with no proactive communication.

## Payment request quality

Two generated network-specific payment requests, so a customer could not select a different network within the flow.

Two displayed an address and an asset name and left the network to the customer's wallet. Those two accounted for every wrong-network incident we had during the month.

This single design difference was the largest driver of support load.

## Underpayment handling

Two allowed a configurable tolerance. One rejected and refunded anything short, including by cents. One credited short payments as complete, which is a loss.

## Refunds

Two refunded from their own balance on instruction. One required us to hold a float. One did not handle refunds at all.

## What we would use

The provider with network-specific payment requests, a configurable tolerance, daily settlement and a stated conversion rate before execution.

That was not the cheapest on headline rate. It was the cheapest once support hours were counted, by a wide margin.

The provider with the best headline rate had the worst payment request design and generated more wrong-network incidents than the other three combined.
