How to Choose Stablecoin Payments Infrastructure

A payment provider choosing stablecoin infrastructure is deciding three things at once: who controls the wallets under its payment flows, how platform fees scale as volume grows, and how much reconciliation stays manual. Those decisions now carry real volume. Visa’s Onchain Analytics dashboard shows $12.0 trillion in adjusted stablecoin transaction volume over the past 12 months, as of September 2026, and McKinsey and Artemis Analytics estimate B2B stablecoin payments at about $226 billion a year, up 733% in 2025. At that scale, a per transaction fee or a manual gas top up stops being a rounding error and becomes a margin line.

This guide is for heads of payments, CTOs and treasury operations leads at crypto-native PSPs, traditional PSPs adding stablecoin rails, and B2B cross-border and remittance companies. It sets out the criteria to evaluate, compares Utila with the routes PSPs usually consider, and shows how Utila customers run payouts and collections in production. It does not cover licensing strategy in depth; the Licensed Partner Network page covers launching in a market before your own license is granted.

Payment Operations on Stablecoin Rails

Stablecoin rails remove correspondent-banking delays, but they move the operational burden onto the wallet layer. Every merchant, payer and payout corridor becomes a set of addresses that must be created, funded with gas, screened, approved and reconciled. A PSP that runs this through one omnibus wallet, or through an exchange account, can move money but cannot attribute it, which is the first thing finance and compliance ask about. Three concerns shape almost every PSP evaluation Utila sees:

• Wallet Volume and Attribution. PSPs need a unique deposit address per merchant, payer or flow, created by API and grouped so policies apply per segment. Without it, incoming payments are matched to senders by hand.

• Fee and Gas Economics. Payout margins are thin. Platform fees charged per transaction or in basis points, plus native-token gas on every transfer, can consume the spread on a corridor. Mandioca reported a single large USDT transfer nearly wiping out its margin before it moved to sponsored transfers.

• Control over Liquidity and Margin. When custody, ramps and liquidity come from one bundled provider, that provider sets the FX spread and becomes a single point of failure. PSPs increasingly want to own the wallet layer and connect to several ramps and liquidity providers per corridor, an approach set out in Utila’s Own the Stack guide.

Each of these concerns maps to a specific platform capability, and the next section sets out how Utila addresses them.

Utila for Payment Providers

Utila is a digital asset and stablecoin infrastructure platform used by more than 400 companies, built on MPC key management with a policy engine, APIs and integrations across 100+ blockchains. For PSPs, the relevant parts are the ones that turn payment flows into governed, attributable wallet operations.

Platform Capabilities

• API-First Wallets and Deposit Addresses. Wallet-as-a-Service creates wallets and addresses through REST APIs, with webhooks for deposits, confirmations and approval requests, so each merchant or payer gets its own address and every inbound payment arrives attributed.

• Batch Payouts under Policy. Batch transfers combine many recipients into one signed transaction, with one token approval and one reconciliation event per payout run. On EVM chains, this also cuts gas, since the fixed transaction cost is paid once instead of per recipient.

• Gas Abstraction. Dedicated gas wallets and sponsored transfers let wallets that hold only stablecoins send payments. On Tron, the Gas Station delegates Energy from one pooled balance per vault, so sending wallets hold no TRX and each USDT transfer costs up to 70% less in Energy than burning TRX. On EVM chains, multi-step flows can run as one sponsored transaction.

• Policy Engine and API Co-Signer. Quorum approvals, transfer limits, address whitelisting and role-based access govern every transfer. The API co-signer runs on any virtual machine or cloud and signs automatically only within the rules you define.

• Embedded Compliance. Screening integrates with Chainalysis, Elliptic and TRM Labs inside the transaction workflow, and Notabene handles travel rule messaging.

Stablecoin Payment Use Cases

• Merchant Pay-Ins. Unique deposit addresses per merchant or checkout, with screening, payer attribution and automated sweeping into central treasury.

• Mass Payouts. Contractor, marketplace and remittance payouts executed as approved batches across multiple chains.

• Cross-Border B2B Collections and Supplier Payments. A wallet per client or flow for exporters, importers and FX settlement, as run by BLOXtrade and HopNow.

• Treasury and Liquidity. Treasury Management consolidates balances, while on/off-ramp partners such as Bridge and counterparties on Utila Link provide fiat conversion and liquidity.

• New-Market Launches. The Licensed Partner Network lets a PSP operate under a partner’s MiCA, MTL or equivalent coverage while its own license is pending, which Utila notes can take 12 to 24 months to obtain directly.

These capabilities only matter if they hold up under the specific tests a PSP should run, which the decision framework below sets out.

Decision Framework for PSP Stablecoin Infrastructure

The table below lists the nine criteria that most often decide a PSP evaluation, what to test for each, and the evidence worth requesting from any vendor, Utila included. Asking for evidence matters because most vendors claim most of these capabilities, while far fewer can show how they behave in a live payout run.

Criteria tell you what to test; the comparison below shows how the common routes to market tend to answer them.

How Utila Compares for Payment Providers

PSPs usually weigh four routes: a dedicated wallet platform such as Utila, a bundled provider that combines custody, ramps and payments, wallets held at an exchange, or an in-house build. The archetype columns describe common patterns rather than any named vendor, so confirm specifics in each vendor’s contract.

The last row is where customer experience is most useful, because time to production depends on how a platform behaves with real merchants and corridors.

Payment Providers Running on Utila

The PSPs below came to Utila with the same problems this guide describes: fragmented wallets, gas eating margin, and pricing that rose with every transfer. Their case studies show which capability resolved which problem.

1. Afriex sends money from the US, Canada, the UK and Europe to Africa and runs a B2B portal for hundreds of businesses. Its stablecoin operations were split across several exchanges and wallet providers. After consolidating on Utila’s Wallet-as-a-Service, Stablecoin Payments and Treasury Management, it expanded from 5 to 23 African payout countries. “Utila has allowed us to consolidate our operations in one platform,” said Ifeanyi Awa, Head of Product.

2. BLOXtrade handles collections for exporters and supplier payments for importers across the US, Brazil, Hong Kong and Singapore. It moved off a single main wallet with transaction-based fees to a wallet per client and flow, sponsored transactions and predictable pricing.

3. Mandioca runs stablecoin B2B payments for Latin American importers and exporters and moved to Utila after gas on a single USDT transfer nearly erased its margin. It now uses unlimited wallets, sponsored transfers and Chainalysis screening through the API.

4. XEROF, a regulated Swiss VASP offering IBAN accounts and cross-border settlement, used Business Continuity to mirror its existing environment and completed the connection to its internal systems in under a week.

5. SquareFi, which provides accounts, cards, digital asset processing and payouts to other fintechs, replaced an in-house MPC stack after a year of building it. “We tried to build it for a year,” said co-founder Anton Lobintsev.

Each of these teams followed a similar sequence from evaluation to production, outlined below.

From Evaluation to Production

Most PSP rollouts on Utila follow five steps. The order matters because wallet structure and policy design are hard to change once merchants hold addresses.

1. Map Flows and Corridors. List pay-in, payout, sweep and conversion flows by corridor, stablecoin and chain, and estimate quarterly outbound volume for plan sizing.

2. Design Vaults, Wallet Groups and Policies. Separate entities or business lines into vaults, group wallets by merchant segment, and set quorums, limits and whitelists per group. Wallet group assignment applies policies to new wallets automatically.

3. Connect Compliance, Ramps and Accounting. Plug in your KYT and travel rule providers, on/off-ramp partners and accounting tools from the integrations catalog.

4. Run in Parallel or Migrate. Mirror wallets, policies and whitelists from your current provider with Business Continuity; vault key import and derivation path matching regenerate identical addresses, so merchants keep paying to the same destinations.

5. Automate and Go Live. Deploy the API co-signer, subscribe to webhooks and start on the Starter plan or a custom plan sized to your volume.

Frequently Asked Questions

What Is Stablecoin Payments Infrastructure for a PSP?

It is the wallet, signing, policy, gas and compliance layer under a PSP’s stablecoin pay-ins and payouts. It creates deposit addresses, approves and signs transfers, pays network fees, screens counterparties and produces the records finance reconciles against. Fiat conversion usually comes from separate ramp partners connected to that layer.

Does Utila Charge per Transaction?

Utila plans are subscriptions sized by outbound transaction volume, active wallets, vaults and users. Utila does not charge per transaction. The Starter plan costs $799 per month for 12 months, billed quarterly, and covers up to $3M in outbound volume per quarter and 1,000 active wallets. Larger PSPs move to custom Growth, Pro, Scale or Enterprise plans.

Can Wallets That Hold Only Stablecoins Send Payments without Native Gas Tokens?

Yes. Utila funds network fees from dedicated gas wallets and supports sponsored transfers, so a wallet holding only USDC or USDT can send without its own ETH, SOL or TRX balance. On Tron, the Gas Station funds transfers from one pooled balance per vault, cutting Energy cost per transfer by up to 70%. On Sui, stablecoin transfers can run at zero network fees.

Can We Keep Our Existing AML and Travel Rule Providers?

In most cases, yes. Utila integrates Chainalysis, Elliptic, TRM Labs, Crystal Intelligence, Merkle Science, Sumsub and Corsa for screening, and Notabene for travel rule messaging. Screening rules run inside the transaction workflow rather than as a separate review step.

Can We Migrate from Our Current Provider without Changing Deposit Addresses?

Yes, for supported key types. Business Continuity imports ECDSA and EdDSA vault keys into a dedicated Utila vault and matches derivation paths so the same addresses are regenerated. You can run both platforms in parallel before switching.

Which Chains and Stablecoins Does Utila Support for Payments?

Utila supports 100+ blockchains, including Tron, Solana, Ethereum, Base, Arbitrum, Polygon and other EVM networks, with stablecoins such as USDT and USDC. Teams can add other EVM chains on demand through BYO EVM.
