The only Swiss platform where you hold your own private keys. Trade, stake, and earn across 32 assets with zero-knowledge privacy — backed by Swiss military-grade infrastructure. No custodian between you and your wealth. No minimum deposit. No lock-in. Connect your wallet and start in seconds.
Self-custody vaults with automatic fee management. You hold your keys — the smart contract handles the rest. Swiss infrastructure backup via NitroKey HSM at Mount10.
In a world of escalating conflict — Iran, North Korea, Ukraine — and governments freezing $300 billion in sovereign assets overnight, the question is no longer if your wealth is at risk. It's where you keep it. Mount10 is a decommissioned Swiss military command bunker carved into 2,000 metres of alpine bedrock. Designed to withstand a direct nuclear strike. Private runway access. Armed Securitas perimeter. Faraday-cage shielded server rooms. Your private keys stay in YOUR wallet. BitBank never holds, stores, or has access to your keys. Our smart contracts auto-manage custody fees while you retain full ownership. For clients who want additional protection, NitroKey HSM hardware backup is available at our Mount10 facility.
Nuclear Hardened
Alpine bedrock bunker. Survives EMP, nuclear blast, natural disaster. Your assets endure what banks cannot.
Your Keys. Period.
You own your private keys. Not us. Not any government. Mathematically impossible for anyone to access without you.
Quantum Proof
NIST-certified post-quantum cryptography. Dual-signed with Kyber768 + Dilithium3. Ready for the post-quantum era.
Sovereign Protection
Swiss Banking Secrecy Act. 700 years of neutrality. MLAT process takes 18+ months. Your assets, your jurisdiction.
Mount10 · Swiss Military Facility
Your Assets. Your Keys.
2,000 metres of nuclear-hardened alpine granite. Private runway access. Air-gapped HSM. Quantum-proof signatures. We mathematically cannot access your assets.
Zero-Knowledge Privacy
Compliant privacy. Nota contradiction.
You deposit regulated assets — USDC, ETH, XDC, BTC. Standard, compliant, transparent. Then Bit Bank wraps your activity in zero-knowledge cryptography. Your trades, balances, and positions become invisible on-chain — verified by Groth16 ZK-SNARK proofs without revealing any details. The deposit is compliant. The privacy happens inside our infrastructure. Swiss regulators accept this architecture because we're not hiding the source of funds — we're protecting the financial privacy of legitimate users. This is not a privacy coin exchange. This is a private Swiss technology provider, built with mathematics instead of marble.
ZK Shield
Deposit clean, regulated assets. ZK Shield wraps them in Groth16 proofs. On-chain link broken. Identity invisible. Compliant at entry, private inside.
Private Subnet
All trading activity executes on Bit Bank's sovereign XDC subnet. Only ZK proofs of valid state transitions reach the public chain. Nobody sees your trades.
ZK-KYC
Complete identity verification once. A zero-knowledge proof attests you passed — without storing your documents. Regulators verify the proof. Your data stays with you.
Railgun Compatible
Deposit RAIL for on-chain privacy across EVM chains. Railgun is a privacy protocol, not a privacy coin — fully compliant, used by institutions on Ethereum and Polygon.

About Us
Swiss heritage. Digital future.
Bit Bank is a Private Swiss Digital Fortress platform combining the discretion of traditional Swiss banking with the innovation of decentralised finance. We believe financial privacy is a fundamental right — not a feature to be toggled on.
Our infrastructure sits inside Mount10 — a decommissioned Swiss military bunker deep in the Alps. Your private keys stay in YOUR wallet — we never hold them. For clients who opt into managed custody, NitroKey HSM hardware provides additional key backup. Every transaction is protected by zero-knowledge cryptography.
We offer custody, spot and futures trading, precious metals, hedge fund vaults, tokenised bonds, OTC desk services, lending, and wealth management — all accessible through one platform, one account, one relationship.

Security Infrastructure
Five layers of protection.
From the physical bunker to the cryptographic proof, every layer of Bit Bank is built to be impenetrable.
BB Key
Your personal hardware security key
Every custody client receives a BB Key — a NitroKey HSM2 hardware device branded with the Bit Bank mark. This device holds your personal MPC key shard. Without your BB Key, nobody — not Bit Bank, not Mount10, not any government — can access your assets.
Your keys are split into three shards using Multi-Party Computation (MPC). Shard 1 lives inside a Thales HSM at Mount10 (Switzerland). Shard 2 lives in a separate HSM in Liechtenstein. Shard 3 lives on your BB Key. Any two of three shards reconstruct the key — meaning you always hold veto power over your own assets.
✓ FIDO2/WebAuthn compliant
✓ Tamper-evident hardware
✓ USB-A and USB-C
✓ Open-source firmware
✓ Bit Bank custom engraving
✓ Secure courier delivery
Swiss Fort Knox — Mount10
Physical infrastructure
Mount10 is a decommissioned Swiss military bunker carved into alpine bedrock. Built to withstand nuclear attack, it now houses some of the most sensitive data in Europe. Bit Bank's HSM servers operate inside this facility.
✓ Nuclear-hardened bedrock
✓ 24/7 armed Securitas guard
✓ Biometric + keycard entry
✓ Faraday cage shielding
✓ Redundant power + cooling
✓ Seismic isolation
NitroKey NetHSM
Cryptographic hardware
All private keys are generated and stored inside Thales Luna Network HSM hardware certified to Military-grade — open-source NitroKey NetHSM hardware with tamper-evident casing. Keys are generated inside secure enclaves and backed up on encrypted iStorage datAshur drives.
✓ Military-grade certified
✓ Common Criteria EAL4+
✓ Tamper-responsive enclosure
✓ AES-256 + ECC key generation
TOR & Private Network
Network privacy
Bit Bank natively supports TOR onion routing — your connection passes through multiple encrypted relays, making it impossible to trace your IP address or location. For institutional clients, we offer a dedicated VPN tunnel to Mount10's infrastructure via Swiss IP addresses only.
✓ TOR .onion endpoint
✓ Swiss-only VPN option
✓ No IP logging
✓ End-to-end encryption
Quantum-Proof Cryptography
NIST FIPS 203/204/205 post-quantum algorithms
Quantum computers will break ECDSA and RSA within the next decade. Bit Bank is ready today. All key exchanges use ML-KEM (Kyber768) — NIST's approved post-quantum key encapsulation. All transaction signatures use ML-DSA (Dilithium3) — quantum-resistant digital signatures. Every transaction is dual-signed: classical ECDSA for blockchain compatibility plus ML-DSA for quantum resilience. If quantum computers break ECDSA tomorrow, your assets remain protected.
◆ ML-KEM (Kyber768) key exchange
◆ ML-DSA (Dilithium3) signatures
◆ SLH-DSA (SPHINCS+) hash backup
◆ AES-256 + SHA-3 (already safe)
◆ Hybrid dual-signing on all txs
◆ Harvest-now-decrypt-later proof
Zero-Log Architecture
We cannot disclose what we do not collect
Bit Bank is architecturally incapable of complying with data requests for information it never collects. No IP addresses are logged. No browsing history. No device fingerprints. No metadata. KYC compliance is achieved via zero-knowledge proofs — we verify you passed identity checks without storing your personal documents. Your trading history is on-chain and ZK-shielded; only you hold the viewing keys. Under Swiss law (FADP Art. 6), we minimise data collection by design.
✓ Zero IP logging by architecture
✓ ZK-KYC — proof without exposure
✓ Client holds own viewing keys
✓ FADP data minimisation compliant
✓ Swiss MLAT jurisdiction only
✓ MPC keys — we can't access alone
7-Layer Defence Network
Defence in depth — military-grade topology
Seven distinct security layers separate the public internet from your private keys. Trading runs at under 50ms latency through the fast path. Custody operations route through Tor hidden services terminating inside Mount10. The HSM layer is physically air-gapped — no network interface exists. Communication via QR code and USB only.
Bit Vault AG (trading as Bit Bank) operates under VQF (Verein zur Qualitätssicherung von Finanzdienstleistungen) — a FINMA-supervised Self-Regulatory Organisation for financial intermediaries. This ensures compliance with Swiss Anti-Money Laundering Act (AMLA) while maintaining the privacy standards that make Swiss banking unique. ZK-KYC allows us to verify identity for regulated services without storing personal documents on our systems.
Zero-Knowledge Proof Infrastructure
Groth16 ZK-SNARKs on XDC Network
Every layer of Bit Bank is protected by ZK-SNARK cryptographic proofs — the same zero-knowledge technology used by Zcash, Tornado Cash, and institutional blockchain systems. Our implementation uses Groth16 proving system with Poseidon hash functions and BN254 elliptic curve pairings. Proofs are generated client-side and verified on-chain, meaning your private data never leaves your device.
◆ZK Shield — Break on-chain links between deposits and withdrawals
◆ZK-KYC — Prove identity compliance without revealing personal data
◆ZK Proof of Reserves — Monthly solvency proof without exposing positions
◆ZK Dark Pool — OTC trades with zero information leakage
◆ZK Settlement — Cross-chain bridge with privacy preservation
◆Private Subnet — XDC sovereign chain, invisible to public explorer
Bit Bank Secure Network Architecture
How ZK proofs work: When you trade on Bit Bank, a cryptographic proof is generated on your device that says "this trade is valid" without revealing who traded, what amount, or at what price. The proof is verified on-chain by our Groth16 Verifier smart contract. The blockchain confirms validity — but learns nothing about the trade details. This is mathematically guaranteed privacy, not policy-based privacy.
Self-Custody Option
Your keys, your rules
Don't want us to hold any keys at all? Connect your own wallet — MetaMask, XDC Pay, WalletConnect, or any Web3 wallet — and trade directly. You maintain full self-custody with zero counterparty risk. Your keys never touch our servers. We provide the exchange, the liquidity, the tools — you provide your own security.
