The Private Blockchain Layer
EXPI doesn't run on a public chain experiment. Haven's blockchain is private, permissioned, and purpose-built for financial transactions — fast enough for a billion users, cheap enough for everyday spending.
Ultra-Fast Settlements
Every card swipe, booking, and payment settles in under 3 seconds — not minutes, not hours. Irreversibly finalised, no confirmations required.
Cost-Effective Transactions
Near-zero fees on every transaction. No gas wars, no network congestion pricing. Enterprise-scale settlement at a fraction of the cost of traditional rails.
Private, Permissioned Chain
Not a public experiment. EXPI runs on a private, permissioned blockchain purpose-built for financial services — controlled, auditable, and regulated from day one.
Complete Audit Trail
Every transaction is written to an immutable ledger. Every action has a permanent, verifiable record. Regulators, auditors, and users can trust what they see.
600,000+ TPS Target
Infrastructure engineered to handle a billion users without slowing down. Built on commodity hardware with linear horizontal scaling as demand grows.
Delegated Proof-of-Power
Our consensus gives all validators equal selection probability — stake-agnostic fairness. 66% BFT quorum required for finality, preventing forks mathematically.
Smart Contracts.
Accountability at Scale.
Every EXPI action is governed by a smart contract. Rules are code — transparent, immutable, and self-executing. No human can override a committed transaction. No hidden policy changes. No exceptions.
This isn't just a technical feature — it's a trust mechanism. Investors, regulators, and users can verify exactly how the platform behaves, because the rules live on-chain and can't be altered after the fact.
Rules Encoded in Code
Every EXPI action — payments, rewards, mobility bookings, token transfers — is governed by a smart contract. The rules are transparent, immutable, and self-executing.
No Human Override
Once a contract is committed, no employee, executive, or third party can alter or reverse it. Accountability isn't a policy — it's architecture.
Automated Execution
No manual steps. No counterparty risk. No settlement delays. When conditions are met, the contract executes — instantly and exactly as written.
On-Chain Accountability
Every contract execution is recorded. Disputes are resolved by the ledger, not by customer service. Transparent for users, defensible for compliance.
You Are the Key.
Passwords get stolen. PINs get guessed. Devices get lost. Haven replaces all of it with one thing that can't be replicated — you. Continuous biometric verification, hardened against AI spoofing, with zero data leaving your device.
Continuous Verification
Your face authorises every action — not just login. Our verification engine runs invisibly and continuously. The moment it detects it isn't you, execution stops.
On-Device Only
Your biometric data never leaves your phone. Processing is local. We receive a boolean signal — true or false — never your identity data. Zero data exposure.
Anti-Deepfake Liveness
Hardened against AI-generated faces, GAN spoofs, 3D masks, 2D photos, and video replay attacks. State-of-the-art resistance to every known spoofing vector.
Stolen Device Protection
Stolen keys don't work. Every transaction requires a live biometric match at the moment of signing. Physical possession of your phone grants zero transactional access.
Quantum-Proof Cryptography
NIST-standardised Falcon post-quantum signatures on all validator votes and block proposals. Future-proofed today against tomorrow's quantum computing threats.
Security Circle Recovery
No seed phrases. No single points of failure. Recovery uses biometric-verified trusted contacts as a social layer — eliminating the most common cause of permanent asset loss.
The EXPI Approach
Three principles.
Engineered without compromise.
Instant Settlement
Transactions finalised in seconds. Fees so low they are never a reason not to transact.
Accountable
Every action governed by code, recorded forever.
Verifiably Secure
Identity anchored in biology, not passwords.
