Architecture

Trade across blockchains without giving up custody of your assets — powered by ICP's Chain Fusion.

Core Principles

Principle	Description
🔐 Non-Custodial	You hold your keys — assets never leave your control
🌐 Chain Fusion	Native BTC, SOL, ICP support — no bridges
⚡ On-Chain Performance	CEX-grade matching running in ICP canisters
✅ Verifiable	Deterministic execution with full audit trails

Performance

Matching engine: ~400 ns per order (running fully on-chain)

Throughput: 1+ million operations per second

Finality: 1-2 seconds (ICP consensus)

Metric	Performance
Limit order	~400 ns
Cancel order	~240 ns
Best bid/ask	14 ns

ICP Advantage

Our matching engine is ready for sub-second finality. As ICP consensus improves, Vortum users benefit automatically.

How It Works

1. Connect

Sign in with Internet Identity, NFID, OISY wallet, or connect your Solana/Bitcoin wallet directly. Your cryptographic identity becomes your trading account — portable and fully under your control.

2. Deposit

Send assets directly from any supported blockchain. Each account receives unique deposit addresses secured by threshold signatures.

3. Trade

Place orders against the on-chain order book. Matching is deterministic and verifiable — orders are processed in the sequence they arrive at the canister.

4. Withdraw

Move assets to any address on supported chains. Withdrawals are signed using threshold ECDSA — no hot wallets, no single points of failure.
