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. 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. Incoming EUR converts to USDC on receipt; timing depends on the rail and the checks each payment needs. 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. SOC 2 Type 2 certified. Our own licences are in flight and flows run on licensed partner rails today.
• Venly-managed wallets. Where applicable, wallets are VENLY_MANAGED on Venly's wallet infrastructure.

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, and which are still roadmap?

Agent-ready as a shortcut

Connect our docs MCP to your IDE agent and it can scaffold the first calls of the integration. The API surface is small on purpose, so a product engineer can ship it without a crypto specialist.

FAQ

Do we need a crypto license to offer this? It depends on your role, flow and jurisdiction. The three models above show where the regulated services sit in each case.

How long does integration take? The core flow is three API calls (account, virtual IBAN, transfer). Time to production depends mostly on onboarding and compliance review.

Which stablecoins and chains? USDC, EURC, USDT and USDS, on the chains configured for your account (for example Base, Avalanche and Polygon).
