Why Integrate

What Byzantine unlocks
for your platform.

Returns on idle balances are becoming a standard feature across fintech platforms. Byzantine provides the technical infrastructure to offer them — without building it from scratch.
New revenue streams
Monetise idle client balances. Earn fees on AUM without taking market risk or building complex treasury operations.
Stickier deposits
Give users a reason to keep capital on your platform. Returns are a strong retention lever in fintech — higher balances, lower churn.
Faster client acquisition
Returns attract new users and increase conversion. Launch an earn programme in weeks, not months — API-first integration means you ship before competitors do.
Integration options

Two ways to integrate

Both paths support full customisation of strategy, risk profile, and currency allocation to match your platform's needs.
Direct access

Access via existing wallets

If your platform already provides wallets to users, Byzantine's infrastructure can be accessed directly from those wallets — no additional development required.
Compatible with existing wallet infrastructure
No frontend development needed
KYC/KYB included
Reporting and accounting built-in
Strategy and risk profile customisable to your needs
API-native

Build a fully embedded experience

Integrate directly via our REST API and SDK. Full control over the user experience — your frontend, our infrastructure.
REST API + SDK
Sandbox environment
Webhooks for real-time updates
Dedicated tech support on Slack

How it works

Simple by design

01
Define your strategy
Use Byzantine's standard strategies or define your own parameters: target return, accepted collaterals, insurance coverage, and liquidity profile.
02
Integrate
Connect via API or through direct wallet access. Choose EUR, USD, or both. Full KYC/KYB onboarding with dedicated support.
03
Deploy
Users deposit via stablecoin or bank transfer. Via the infrastructure, capital is deployed into overcollateralised lending protocols — Aave, Morpho, Sky.
04
Earn
Your clients' returns accrue from borrower interest through DeFi protocols. They can withdraw anytime in under 60 seconds. You get full transparency and reporting via API.
Security & Insurance

Designed to mitigate risk at every layer

The infrastructure is built with institutional due diligence in mind — from smart contract security to optional insurance coverage.

8 independent security audits

Audited by Zellic, Spearbit, ChainSecurity, Blackthorn, and Cantina. All custom adaptors audited separately.

Real-time monitoring

Continuous on-chain monitoring via Hypernative, with AI-powered behavioural analysis that can trigger preventive withdrawals before an incident occurs.

Immutable smart contracts

No backdoors, no admin functions. Deployed code cannot be modified. Strategy changes require a 3-day timelock with independent veto rights.

Real-time monitoring

Borrowers deposit 120–150% collateral. Automatic liquidation triggers if collateral drops below threshold. No bad debt event recorded to date.*

Fully compliant

Optional coverage on 100% of principal against hacks, exploits, and operational incidents. Cap: €20M per client.

Audited partners

Keyrock (regulated DASP), Portofino (FX), Aon (insurance), all independently auditable.
Regulatory

Start earning in a few clicks

Byzantine is a technology infrastructure provider. Regulated functions are performed by third-party partners.
Designed to operate within MiCA
Architecture built to align with MiCA regulatory standards, enabling adoption by regulated European platforms and institutions.
Non-custodial by design
Byzantine does not hold, control, or have access to client funds. All assets remain under user control via self-custody or institutional custodians.
AML/KYC on all users
Identity verification and anti-money laundering procedures applied to every user, meeting institutional compliance requirements.
Q&A

Common questions

Straight answers to the questions that matter most about your money.
How fast can we go live?

Most integrations go live within 2–3 weeks. White-label deployments can be faster. We provide a sandbox environment, dedicated tech support, and a launch checklist to keep things on track.

Is this fully white-label?

Yes. Your users see your brand, your interface, your experience. Byzantine runs entirely behind the scenes — strategy execution, compliance, reporting, and infrastructure.

What currencies are supported?

EUR and USD. Your users can deposit via stablecoin (USDC, EURC) or bank transfer. Fiat on/off-ramp is built in via Bridge, with zero slippage.

How is risk managed?

All lending is overcollateralised — borrowers deposit more collateral than they borrow. Principal is insurable against hacks, exploits, and operational incidents. Strategy is managed by a regulated digital asset service provider. Real-time monitoring runs 24/7.

What are the commercial terms?

Performance fee of 10% on returns. Insurance is optional at 2% of AUM. All other costs — fiat conversion, custody, curator fees, gas — are covered by Byzantine. Let's talk through the details on a call.
