Banking Infrastructure for Crypto Exchanges & Digital-Asset Platforms.
EU IBANs, MiCA-aligned accounts, and crypto cards — without de-risking risk.

Cryptocurrency exchanges, custodians, and digital-asset platforms operate at the intersection of two regulatory universes — crypto-asset law and payments law — yet most mainstream banks still treat the sector as uninvestable. The result is chronic de-risking: accounts closed, correspondent relationships withdrawn, and fiat on/off-ramps reduced to a bottleneck that constrains growth. Codego is purpose-built to fill exactly that gap. As a European Banking-as-a-Service provider with native EU IBAN issuance, SEPA Instant connectivity, Visa and Mastercard BIN sponsorship, and a card programme designed from the ground up to handle stablecoin-funded spend, Codego gives digital-asset platforms the regulated banking layer they need — delivered in days, not months.

The industry challenge

The digital-asset sector has matured considerably since 2012. Regulated spot exchanges, licensed custodians, institutional prime brokers, stablecoin issuers, and DeFi on-ramp providers now collectively serve tens of millions of verified users across the European Economic Area. Yet the banking infrastructure available to these businesses has not kept pace. Traditional banks, under pressure from correspondent banking guidelines and their own risk committees, continue to refuse or abruptly terminate accounts for crypto-facing entities — regardless of the operator's own regulatory standing. The consequences are concrete. Without a reliable fiat on/off-ramp, an exchange cannot settle EUR withdrawals to clients promptly. Without segregated client-money accounts, it cannot demonstrate MiCA Article 70 compliance — the Markets in Crypto-Assets Regulation requirement that platforms holding client funds do so in a manner that protects those funds in insolvency. Without Travel Rule infrastructure integrated into the payment layer, every outgoing wire becomes a compliance liability under FATF Recommendation 16 and the EU's Transfer of Funds Regulation (TFR), which extended Travel Rule obligations to crypto-asset transfers from December 2024. Layered on top of these structural problems are the operational demands of a 24/7 market. Crypto trading does not pause for SEPA batch windows. Clients expect near-instant EUR credit when they liquidate a position at 2 a.m. on a Sunday. Standard SEPA Credit Transfer cycles — typically settled once or twice a day on business days — are structurally incompatible with that expectation. SEPA Instant, which settles within ten seconds around the clock, is the only payment rail that matches crypto-native user behaviour. Know-Your-Transaction (KYT) requirements add a further layer. Regulators and banking partners alike now expect crypto platforms to screen incoming and outgoing blockchain transactions against sanctions lists, identify high-risk counterparties, and produce source-of-funds documentation for material flows. Integrating KYT outputs into a banking relationship — so that, for instance, a flagged deposit automatically holds a corresponding fiat withdrawal — requires a banking partner willing and technically capable of receiving those signals. Finally, the card issuance dimension is emerging as a competitive differentiator. Users who hold stablecoin balances — USDT, USDC, EURC — increasingly want to spend those balances at point of sale without a manual off-ramp step. Delivering that requires a card programme with native crypto conversion logic, not a bolt-on workaround. Mainstream card issuers have been slow to support this use case; specialist infrastructure providers have not.

What banking infrastructure must deliver

EU IBAN issuance with SEPA Instant

Every client of a digital-asset platform that handles EUR needs a credible, functional IBAN — ideally one issued in a major EEA jurisdiction, not routed through an obscure intermediary that triggers correspondent-bank flags. Codego issues native EU IBANs across six countries, each fully enabled for SEPA Credit Transfer, SEPA Instant Credit Transfer (SCT Inst), and SWIFT. SEPA Instant settles in under ten seconds, twenty-four hours a day, seven days a week — a rail that finally matches the settlement expectations of crypto-native users. For more on the mechanics, see the IBAN issuance glossary entry and SEPA Instant overview.

Segregated client-money accounts

MiCA Article 70 requires crypto-asset service providers holding client funds to keep those funds segregated from their own operational capital and protected in insolvency. Delivering this operationally means a banking partner capable of issuing individual or pooled-with-ledger sub-accounts, ring-fenced at the account level, with clear beneficial-ownership attribution. Codego's core banking layer supports multi-account architectures specifically designed for client-money segregation, enabling exchanges to demonstrate compliance without building bespoke reconciliation systems from scratch.

Crypto and stablecoin-funded card programmes

A growing segment of digital-asset users wants to spend crypto balances — particularly stablecoins — at Visa and Mastercard merchants without a separate withdrawal step. Codego's white-label crypto card programme handles on-the-fly conversion at point of sale: the cardholder's stablecoin or crypto balance is liquidated at the moment of authorisation, and the merchant receives a standard fiat settlement. This is a first-class feature of Codego's stack, not an afterthought. Both Visa and Mastercard BIN sponsorship is available; Apple Pay and Google Pay provisioning completes within twenty-four hours of card issuance. See the card issuing glossary for context.

Travel Rule and TFR compliance support

Under the EU Transfer of Funds Regulation, all crypto-asset transfers must carry originator and beneficiary data — the blockchain equivalent of a wire transfer's SWIFT message fields. Exchanges need a banking partner that understands this framework and can integrate with Travel Rule solutions (such as TRUST, OpenVASP, or Notabene) at the payment layer. Codego's infrastructure is designed to accommodate TFR data flows, enabling platforms to attach compliance metadata to fiat transfers that correspond to on-chain activity, and to hold payments pending Travel Rule resolution where required.

KYT integration and sanctions screening

Know-Your-Transaction tools — Chainalysis, Elliptic, TRM Labs, and others — generate risk scores and sanctions flags for blockchain addresses and transaction flows. A banking infrastructure layer that can act on those signals is essential: a high-risk inbound crypto deposit should be capable of triggering a corresponding hold on the associated fiat account. Codego's API-first architecture supports webhook-driven account controls, enabling exchanges to build automated compliance workflows that span both the crypto custody layer and the fiat banking layer, without manual intervention for every alert.

Rapid programme deployment and self-service configuration

Time-to-market matters acutely in digital assets, where competitive windows open and close quickly. Codego's end-to-end deployment timeline runs to approximately fifteen days — virtual cards available on day one, physical cards by day fifteen. The self-service portal allows programme managers to configure velocity limits, geographic restrictions, MCC blocks, and FX conversion rules without raising a support ticket for each change. For exchanges launching new products — a stablecoin card for premium users, a separate expense card for institutional clients — this agility is operationally significant. See white-label card and card issuing product pages for programme parameters.

How Codego's stack maps to digital-asset platforms

The Codego product suite addresses each structural need of a regulated digital-asset business in a way that is designed to interoperate, rather than requiring a platform to stitch together half a dozen specialist providers. Fiat on/off-ramp infrastructure. The foundation of any exchange's banking relationship is the ability to receive and send EUR (and increasingly GBP, CHF, and other currencies) reliably and quickly. Codego's Banking-as-a-Service layer provides this via native EU IBANs in six jurisdictions, with SEPA, SEPA Instant, and SWIFT all supported. An exchange can assign a dedicated IBAN to each verified client — enabling precise reconciliation of deposits and withdrawals — or operate a pooled model with internal ledger attribution. Because Codego operates under an NBB electronic-money distribution licence and has Codego Europe SIA in the EMI authorisation process with pan-EU passporting, there is no intermediate correspondent bank whose risk appetite could destabilise the relationship. This is materially different from arrangements where a crypto platform's IBAN is issued by a mid-tier bank that itself relies on a correspondent unwilling to touch digital-asset flows. MiCA-aligned account architecture. The white-label bank and core banking products support the multi-account, segregated-wallet architecture that MiCA Article 70 demands. Exchanges can model their client-money obligations directly within the Codego ledger, with ring-fenced sub-accounts per client or per asset class, and export the account data required for regulatory reporting. Crypto and stablecoin card issuance. The white-label crypto card is the most distinctly crypto-native element of the stack. An exchange or custodian can issue branded Visa or Mastercard cards to its users, funded from stablecoin or crypto balances held in custody. The conversion logic — which stablecoin, at what rate, from which balance priority — is configurable at the programme level. The card processor handles authorisation, clearing, and settlement, while the exchange retains the client relationship and the brand. Both physical and virtual card formats are available; Apple Pay and Google Pay wallets are provisioned within twenty-four hours. For platforms that need to understand the technical underpinning, the BIN sponsorship glossary entry explains how the Visa and Mastercard scheme relationships are structured. Expense and institutional card programmes. Beyond consumer-facing crypto cards, exchanges serving institutional or corporate clients can deploy expense card programmes for their own treasury operations or for business clients who need to manage crypto-funded business expenditure with standard corporate card controls. Integrated compliance touchpoints. The API layer that underpins all Codego products is designed for integration with third-party compliance tooling. Exchanges can connect KYT providers to trigger account-level controls, pass TFR originator data alongside SEPA transfers, and route sanctions-screening alerts into automated hold workflows — all via documented REST APIs, without requiring bespoke development from Codego's side for each integration pattern. The net effect is that a digital-asset platform working with Codego can replace a fragile patchwork of banking relationships — each one vulnerable to de-risking — with a single, API-first infrastructure layer that understands the compliance obligations of the sector and has built its product roadmap around them.

Real-world architecture

Consider a mid-sized EEA-regulated spot exchange — operating under a MiCA CASP licence, serving approximately 120,000 verified retail users, with EUR as its primary fiat currency. Prior to engaging Codego, the exchange maintained fiat operations through a single Eastern European EMI that provided IBANs but lacked SEPA Instant connectivity, resulting in withdrawal delays of up to twenty-four hours and significant user complaints during volatile market sessions. The exchange migrated to Codego's BaaS layer over a four-week transition period. Each verified client was assigned a dedicated EU IBAN, issued natively through Codego's infrastructure, with SEPA Instant enabled by default. Deposit reconciliation — previously a manual process matching incoming SEPA credits to user accounts — became fully automated via the Codego webhook API, which fires an event on every credit received. Withdrawal processing, previously batched twice daily, shifted to near-real-time: a withdrawal request submitted at 3 a.m. on a Saturday now settles to the recipient's bank within ten seconds if their bank participates in SCT Inst. The second phase involved the exchange's stablecoin card product. The platform held approximately €18 million in client USDC balances and wanted to offer a spend card without forcing users through a manual liquidation flow. Using Codego's white-label crypto card programme, the exchange launched a co-branded Visa card. When a cardholder makes a purchase, the authorisation request is routed through Codego's card processor; Codego triggers a conversion event on the exchange's custody layer at the authorised amount, the USDC balance is reduced, and the merchant receives EUR settlement through standard Visa clearing. From the cardholder's perspective, the experience is identical to using a prepaid card; from the exchange's perspective, card spend becomes a low-friction off-ramp that keeps the client within the platform ecosystem rather than withdrawing to a bank account. The exchange also integrated its Chainalysis KYT deployment with Codego's account-control API. High-risk deposit flags — scoring above a defined threshold — automatically place a temporary hold on the associated client IBAN, preventing fiat withdrawal until a compliance officer reviews the blockchain transaction. This workflow, which previously required manual coordination between the compliance team and the banking provider (often taking hours), now executes in under a minute. The architecture is not hypothetical; it reflects the integration patterns Codego's infrastructure is explicitly designed to support, and which digital-asset platforms across the EEA are deploying today.

Frequently asked questions

Is Codego's infrastructure compatible with MiCA client-money segregation requirements?

Yes. MiCA Article 70 requires crypto-asset service providers to hold client funds in accounts that are segregated from operational capital and protected in insolvency proceedings. Codego's core banking layer supports individual client IBANs or pooled accounts with sub-ledger attribution, both of which satisfy the segregation requirement. The account structure can be documented for regulatory reporting purposes, and Codego can provide confirmation letters evidencing the account arrangement for submission to national competent authorities.

How does SEPA Instant work for crypto exchange withdrawals, and is it available 24/7?

SEPA Instant Credit Transfer (SCT Inst) settles in under ten seconds and operates continuously — including weekends and public holidays — unlike standard SEPA Credit Transfer, which follows business-day batch cycles. Codego's EU IBANs support SEPA Instant natively, meaning a client withdrawal request can result in funds arriving at the recipient's bank within seconds of submission, provided the recipient's bank also participates in SCT Inst. Participation now covers the substantial majority of EEA payment accounts. See the SEPA Instant glossary entry for technical parameters.

Can Codego issue IBANs to individual exchange clients rather than just to the exchange itself?

Yes. Codego supports both pooled and dedicated IBAN models. In the dedicated model, each verified client of the exchange receives their own EU IBAN, which they use as their deposit address for EUR transfers. Incoming credits are attributed to the correct client account automatically via Codego's webhook infrastructure. This model simplifies reconciliation significantly and provides a cleaner audit trail for MiCA compliance purposes. The dedicated IBAN model is available under the white-label bank and BaaS product configurations.

How are stablecoin-funded card transactions processed at point of sale?

When a cardholder makes a purchase using a Codego-issued crypto card, the authorisation request arrives at Codego's card processor in real time. Codego triggers a conversion event — liquidating the required stablecoin or crypto balance at the exchange's custody layer via API — and approves the authorisation in EUR (or the local transaction currency). The merchant receives a standard Visa or Mastercard fiat settlement; the cardholder's crypto balance is reduced by the equivalent amount. The conversion rate, slippage tolerance, and balance priority order (e.g. USDC before USDT) are configurable at the programme level through the self-service portal.

Does Codego support Travel Rule (TFR) data requirements for linked fiat transfers?

Codego's API layer is designed to accept and pass structured originator and beneficiary data alongside SEPA transfers, consistent with the EU Transfer of Funds Regulation requirements that extended Travel Rule obligations to crypto-asset transfers from December 2024. Exchanges can attach TFR-compliant metadata to withdrawal instructions submitted via the API, and Codego can hold outgoing payments pending data completion where required. Integration with third-party Travel Rule solutions — such as Notabene, TRUST protocol participants, or OpenVASP-compatible systems — is supported through standard webhook and API patterns.

What is the typical timeline to launch a branded card programme for a crypto exchange?

Codego's end-to-end onboarding and programme launch timeline is approximately fifteen days. Virtual cards — which can be provisioned to Apple Pay and Google Pay wallets within twenty-four hours of issuance — are available from day one of programme go-live. Physical card production and delivery adds the remaining days. Programme configuration — including spending limits, MCC category blocks, geographic restrictions, and FX conversion rules — is managed through Codego's self-service portal without requiring custom development for standard parameters. For non-standard requirements, Codego's implementation team engages directly. See card issuing and white-label card for programme specifications.
