SequChain is the first true DEX that settles in milliseconds. Your keys never leave your device, every trade carries a certificate anyone can verify, and no operator can ever touch your funds.
Every chain since Bitcoin optimises the same design — one global queue, re-executed by everyone, ordered by auction. SequChain doesn't optimise that design. It retires it: settle owned value at the edge, and only pay for consensus when strangers genuinely share state.
A trade is final the instant its certificate is sealed — no block confirmations, no reorgs. Measured on the hosted testnet: p50 2.5 ms, 99% under 5 ms over 200 live transactions.
Log-scaled bars (times span 2.5 ms → 60 min). Competitor finality figures are typical published values; SequChain's is measured — sub-millisecond in-process (p50 0.4 ms per core), ~2.5 ms end-to-end through the hosted node.
On our 16-core testnet box SequChain sustains a measured ~4,700 TPS (≈850 TPS/core) — more than Solana's or Sui's entire network. Owned transfers touch disjoint state, so aggregate throughput grows as validator machines are added.
* Measured on the hosted 16-core box (scaling sweep 1→16 shards). Scaling is sublinear on a single machine (disk/IO bound) — very high aggregate TPS needs many independent validator machines, which this testnet does not yet run. No unproven "100k TPS" claim.
People call most "exchanges" decentralized. Here's the honest test — and where SequChain lands on every line.
No central sorting office, no global queue. You seal a proof on your device; witnesses stamp it; the stamps fold into one certificate that is finality. Each letter takes its own path — in milliseconds.
Your coins, your balances — touched only by you.
A pool or market many parties write at once.
Cryptographic. Finality is a BLS certificate + Merkle proof — math, not a majority vote.
<5ms finality. Owned transfers finalize at the edge in milliseconds (p50 2.5ms, 100% <5ms, measured); ~4,700 TPS on a 16-core box.
Permissionless. Anyone runs a witness (N=3f+1); cheating is slashable by anyone, no vote.
From your signed intent down to governance — every layer is a real, open, tested crate.
A hard-capped 100 billion SC secures and meters a settlement universe built for $100 trillion of real-world value. Issued only through a treasury that mints on the real engine and can never exceed the published cap.
Your browser generates an Ed25519 key and a recovery phrase. No sign-up, no email — the key never leaves your device.
Grab starter SC, or bridge in wBTC / wETH / wUSDT from any exchange to trade on the fast path.
Buy, sell, or send — you sign it, it settles in milliseconds, and you can verify the proof yourself in the Explorer.
Truth by math. Witnessed by humans. Owned by everyone.
