Frequently Asked Questions

Straight answers to the questions that matter most about your money.
What is Byzantine?

Byzantine is a digital investment product designed to help companies and investors earn safe, predictable returns on their cash or digital assets. Think of it as a high-quality savings account or money market fund, but built on transparent blockchain technology, with double the returns.

How does Byzantine work?

When you deposit funds, we:

  • Convert them into stablecoins (digital dollars or euros that are always 1:1 with fiat currency)
  • Invest them across secure, audited lending markets
  • Manage everything for you: currency hedging, risk monitoring, and liquidity. You simply deposit, watch your balance grow, and withdraw whenever needed.
Why Byzantine?

Byzantine is a fixed-income style product, comparable to bonds or money market funds.

  • Set-and-forget: We manage everything end-to-end - on/off-ramping, FX hedging, rebalancing, diversification, liquidity buffers, risk monitoring, and insurance - so clients can treat this as a turnkey treasury allocation.
  • Base + spread model: We deliver base rate + 400bps at all times. Stability is the priority, but we capture upside when possible - investors are guaranteed the spread, not a capped rate.
  • Capital protection: Backed by a global insurance partner, operated under MiCA regulation, and with assets in tier-1 custody, active risk management.
  • Risk-adjusted diversification: We select only audited, deep-liquidity pools, dynamically rebalancing to maintain safety.
  • Real-time risk monitoring: 24/7 oversight + Keyrock’s proprietary stress testing.
  • Regulated structure: Operated by Keyrock Asset Management under MiCA, AML/CFT regulation.
  • Liquidity-first design: Withdrawals fulfilled in <1 minute under normal conditions, with buffers sized for institutional flows.

Byzantine is built as a bond-like, fully managed credit product designed for treasuries. Investors get stable, risk-adjusted returns with the transparency of on-chain infrastructure. The right comparison set is T-bills, MMFs, and institutional credit strategies.

Where do returns come from?

Returns come from institutional lending markets (Aave, Morpho, Maker), where traders and market makers borrow stablecoins at predictable rates.

We deploy capital exclusively in multi-audited, blue-chip protocols. Capital is placed in overcollateralised lending structures, with conservative LTVs. Assets are insured, regulated, and fully transparent on-chain.

Think of this as a digital version of a credit fund or money market fund.

What's a stablecoin?

A stablecoin is a type of cryptocurrency that’s tied to a real-world currency (like the US dollar or Euro). 1 USDC = 1 USD, always. 1 EURC = 1 EUR, always. This makes stablecoins a safe way to move money and earn yield on-chain without volatility.

Is my money safe?

Yes, safety is our top priority. Assets are:

  • Managed by Keyrock Asset Management, a regulated asset manager.
  • Held in tier-1 custodians (Anchorage Digital, Zodia), or non custodially - depending on your choice.
  • Invested only in battle-tested protocols with multiple security audits.
  • Optionally, you can choose to insure your principal with a global leader in risk coverage.
Does Byzantine control my assets?

Byzantine never controls your assets. You as the holder always retain total control.
