Sub-second finality
A BFT consensus core with pipelined execution finalizes transactions in ~400ms — fast enough for orderbooks, payments and RTGS-style flows.

Settlement infrastructure
Settlement infrastructure
for onchain capital markets
Helix is a modular settlement layer that gives builders sub-second finality, verifiable execution and compliance-ready rails — without giving up self-custody or decentralization.
No credit card · Testnet tokens included · SOC 2 Type II in progress
import { Helix, Asset } from '@helix/sdk';
// 1 · connect to the settlement layer
const helix = new Helix({ network: 'mainnet', key: process.env.HELIX_KEY });
// 2 · atomic, verifiable, sub-second settlement
const tx = await helix.settle({
from: '0x9f2b…c41d',
asset: Asset.USDC,
amount: 2_500_000n,
proof: 'zk-groth16'
});
console.log(tx.status, tx.finalityMs);
→ finalized 412ms ✓ proof verified onchain

Platform
Everything you need to move value onchain
One integration replaces the custody, settlement, compliance and reconciliation stack you'd otherwise build over 18 months.
Verifiable execution
Every state transition ships with a succinct zero-knowledge proof, so counterparties verify correctness without trusting an operator.
Modular by design
Swap the DA layer, prover or sequencer independently. Deploy a sovereign appchain in minutes and inherit shared security from day one.
Compliance rails
Optional attestation registries, travel-rule messaging and policy hooks let regulated institutions transact without leaking counterparty data.
Native interoperability
Light-client bridges to 14 chains with no wrapped-asset risk. Route liquidity across ecosystems in a single atomic transaction.
Realtime observability
Streaming APIs, webhooks and prebuilt dashboards give ops teams ledger-accurate reconciliation and alerting out of the box.
How it works
From integration to settlement in three steps
Connect
Install the SDK or call the REST API. Bring your own keys, an MPC provider or a qualified custodian — Helix never holds user funds.
Execute
Submit intents to the sequencer. Transactions are ordered fairly, executed deterministically and proved in the same block.
Settle & verify
Proofs post to the base layer. Anyone — your auditor included — can independently verify the full ledger history in seconds.
Security
Built for people who cannot afford to be wrong
Security isn't a feature we added later — it's the architecture. Non-custodial by default, formally verified where it counts, and continuously audited.
- Non-custodial architecture. Keys never leave your environment.
- Formally verified core. Consensus and bridge contracts machine-checked in Coq.
- $2M bug bounty. Permanent program with same-day triage.
- Proof-of-reserves. Continuous attestation, published every epoch.
