True instant finality. Native cross-chain support. Infinite scalability.
Currently in testnet • Mainnet launching Q4 2026
Transactions settle faster than you can refresh.
Tetra achieves true instant finality, making blockchain interactions as responsive as traditional web applications.
Transactions complete in 100ms—faster than a typical credit card authorization.
Instant Finality
Probabilistic Finality
Plus Rollups & Oracles
Current blockchain solutions take seconds to finalize. That latency makes real-time commerce impractical.
Here's how 100ms finality transforms the ecosystem:
Advanced architecture that combines speed, security, and simplicity. Each innovation enables new use cases.
From consensus to user experience—every component optimized for real-world adoption.
Traditional blockchains sacrifice speed for security. Tetra achieves both through regional validator networks that process transactions in parallel while maintaining mathematical finality.
Your phone already has bank-grade security chips. Tetra leverages WebAuthn to turn every smartphone into a secure crypto wallet—no seed phrases, no hardware wallets, no complexity.
$2.8B lost to bridge hacks in 2023. Tetra's validator network directly secures Bitcoin and Ethereum assets—no bridges, no wrapped tokens, no custodial risk.

Validators don't download full state. They fetch Merkle proofs on-demand:
On-chain governance votes trigger simultaneous validator upgrades—no manual intervention:
User contracts written in JavaScript, compiled via our in-house stack:
Dynamic shard count (8-64) based on load:

Engineering breakthroughs that enable new use cases impossible on traditional blockchains.
From instant onboarding to self-cleaning state—each innovation solves real production problems.
New validators start validating in under 60 seconds via lazy state hydration. No terabyte downloads—just verify the latest block signature and start.
The breakthrough: Fix critical bugs across ALL validators without coordination.
If 1000 users store identical data, it's stored once and referenced 1000 times. Merkle trees with IPFS-style CIDs.
Run contract queries on your own computer by lazily hydrating Merkle state. Your app fetches only the data it needs, verifies proofs locally, and executes in the same VM validators use.
// Query locally, no RPC needed
const balance = await local_vm.query({
contract: "alice/token",
method: "balanceOf",
args: { user: "bob" }
}); // VM auto-fetches + verifies needed state Cross-shard messages stored in control plane survive validator failures and epoch boundaries. Guaranteed delivery.
Inactive entities expire after 1M blocks (~4 months). No blockchain bloat from abandoned accounts. Active entities auto-refresh.
100ms finality enables applications across trillion-dollar markets. No bridges. No complexity. Blockchain that works as seamlessly as the web.
Ultra-fast settlement: Transactions complete in 100ms—significantly faster than existing blockchains. Ethereum takes 12+ minutes, Solana takes 13 seconds. Customers complete payments and leave immediately.
Market capture: $6.8 trillion payment processing market currently controlled by Visa and Mastercard.
Revenue model: 0.1% transaction fee = $6.8B annual potential vs. traditional 2.9%
Real-time betting: Live odds, wager placement, and instant payout—all in 100ms as plays unfold. Traditional sportsbooks take minutes to settle. No waiting for settlement windows.
Market capture: $203 billion sports betting market where speed determines competitive advantage.
Revenue model: Platform fees + liquidity provision from instant settlement
Native cross-chain: Single atomic transaction across blockchains. No wrapped assets, no bridge vulnerabilities, no waiting for confirmations. $2.8B lost to bridge exploits in 2023.
Market capture: $250 billion DeFi + NFT markets currently fragmented by bridge failures and 12-minute delays.
Revenue model: Cross-chain transaction fees from previously impossible trades
Automated metering: JavaScript smart contracts automatically meter and charge for every API request. No payment processors, no monthly billing cycles. Stripe charges 2.9% + 30¢.
Market capture: $37 billion API management market where payment friction kills adoption.
Revenue model: Platform fees on micro-transactions enabling new business models
Micropayment access: Touch Face ID to unlock premium content for $0.05. No subscription fatigue, no payment form friction, just instant access. Compare to Netflix at $15.49/month.
Market capture: $473 billion digital content market where subscription models are hitting saturation.
Revenue model: Creator platform fees on micro-transactions that were previously impossible
Instant global transfers: 100ms settlement across borders for 0.1% fee vs Western Union's 3-day wait and 8% fees. Money arrives almost instantaneously. Western Union charges $20 on $250.
Market capture: $156 billion remittance market dominated by legacy operators with high fees.
Revenue model: 80x lower fees driving 100x higher volume
Hot-swappable contracts: Found a vulnerability? Push a fix via governance vote. The old script hash is replaced atomically across all validators—no migration, no user disruption.
Traditional approach: Ethereum upgrades require complex proxy patterns and manual user migrations. Solana upgrades can freeze the network for hours.

}Standard JavaScript iteration order varies by engine. We guarantee consistent execution:
// Our compiler ensures deterministic iteration
for (let key in object) {
// Same order on every validator, every time
}Write from multiple shards simultaneously without conflicts:
const uid = xof_derive(state_root, "events", txn_id, nonce);
state.events[uid] = {...}; // ✅ Guaranteed uniqueOrganize entities with inherited permissions:
alice ├─ alice/treasury (private: only you) │ └─ alice/treasury/multisig (protected) └─ alice/storefront (public: anyone) └─ alice/storefront/inventory
Delegate permissions with depth limits:
