Adding a stablecoin leg to your payouts: build, buy, or partner

By Venly Finance | August 3, 2026

PSPs and platforms keep asking the same question: how do we offer stablecoin settlement without becoming a crypto company? The honest build-vs-buy-vs-partner analysis.

Every PSP and platform product team got the same question in 2026: "Our merchants are asking for USDC settlement. Can we offer it?"

The honest answer has three options, not one. Which one is right depends on scale, licensing appetite, and how much of a crypto company you actually want to become.

Option 1 — Build

Everything, in-house: custody, key management, chain integrations, MiCA/CASP licensing, treasury operations, blockchain incident response, and a compliance team that speaks both TradFi and on-chain.

Timeline: 18 months minimum. Ongoing headcount: a dedicated compliance department, a blockchain engineering team, a 24/7 ops rotation. It''s only rational at very large scale — the kind of scale where the alternative''s per-transaction economics stop making sense.

Option 2 — Buy from the consolidated giants

Stripe/Bridge, Mastercard/BVNK, and a small handful of others. Strong for mainstream segments, deep integrations with the payments stack you already use, and increasingly bundled with card acquiring.

The trade-off: you inherit their risk policy and their roadmap. Card networks and payments giants run conservative underwriting. If your book includes any segment they treat as elevated risk — or any segment they''ll treat that way in two years — you''re one policy review away from a migration.

Option 3 — Partner

A settlement layer via API where the stablecoin leg is one optional field on your existing payout flow. The integration is three calls:

1. Onboard the seller once. `POST /accounts` returns an account ID after KYC/KYB. 2. Issue a EUR virtual IBAN with USDC auto-convert. `POST /accounts/{accountId}/virtual-bank-accounts` returns a `referenceCode`. 3. Pay EUR by SEPA to that IBAN. Auto-conversion to USDC happens in minutes. Optionally push on-chain with `POST /accounts/{senderAccountId}/transfers/crypto`.

Licensing flexibility is where the partner model earns its keep. Three engagement models cover the realistic space:

You''re licensed. You hold CASP/VASP/MSB permissions. Venly is your technology provider; wallets are `SELF_CUSTODY` on your keys.
Partner-regulated. Regulated services are delivered through licensed partner institutions. Live today while our MiCA authorization is in progress.
Venly-managed custody. Where applicable, Venly acts as custodian on its wallet infrastructure with `VENLY_MANAGED` wallets.

Weeks to integrate, not quarters. No compliance department to hire.

Diligence checklist for any partner

Whatever you choose, ask these questions on paper:

Who is the regulated contracting party for each service? Payouts, custody, FX. Get names and license numbers.
What custody model applies to your flow? Self-custody, partner-licensed, or provider-managed.
Is every money movement idempotent, with a durable audit trail? Get sample logs.
Which corridors and chains are actually in coverage today — not roadmap, today?

Agent-ready as a shortcut

Connect our docs MCP to your IDE agent and it can scaffold the three-call integration in a minute. The API surface is small on purpose so that a product engineer, not a crypto specialist, can ship it.

FAQ

Do we need a crypto license to offer this? Depends on the model. Three options above; two of them don''t require you to hold your own CASP/VASP.

How long does integration take? The core flow is three API calls (account, virtual IBAN, transfer). Most partners are in staging in days and in production in weeks.

Which stablecoins and chains? USDC, EURC, USDT and USDS on Base, Avalanche and Polygon.
