Finality Time

Instant Trade Execution on Ethereum (and any other chain) with Sub-Millisecond Finality

Speed is critical for traders. Delays in execution can lead to slippage, missed opportunities, and front-running—issues that plague most decentralized exchanges on Ethereum. Traditional on-chain trading is slow, with transactions requiring multiple block confirmations before being finalized. VDEX eliminates these inefficiencies by offering sub-millisecond trade execution, bringing CEX-level speed while preserving DeFi’s transparency and security.

Why Finality Time Matters in Trading

In Ethereum-based trading, finality refers to how long it takes for a transaction to be confirmed and irreversible.

  • The Ethereum mainnet requires ~12 seconds per block, meaning trade settlement can take several blocks under congestion.

  • L2 solutions like Arbitrum & Optimism lower fees but still require batching and delayed finality, making high-frequency trading inefficient.

  • MEV exploits remain an issue across all networks, as transactions can be reordered before execution.

For active traders, these delays cause:

  • Slippage – Prices shift before your order is confirmed, reducing profitability.

  • Front-running – Bots detect pending transactions and insert their own orders ahead of yours, leading to worse fills.

  • Slow Market Entry & Exit – Delayed execution makes risk management harder, increasing exposure to market volatility.

VDEX solves these problems with instant finality on Ethereum (and any other chain), thus ensuring that trades execute at the price displayed—without delays or manipulation.

How VDEX Achieves Instant Trade Finality on Ethereum

Instead of settling every trade directly on Ethereum’s slow and expensive mainnet, VDEX processes trades off-chain in a Zero-Knowledge (ZK) State Channel while preserving on-chain security.

Here’s how it works: 1️⃣ Off-Chain Execution: Trades are processed in ZK State Channels, allowing for near-instant execution without Ethereum’s usual delays. 2️⃣ On-Chain Settlement: Once trades are executed, final state updates are submitted to Ethereum in batches using Virtual Rollups, ensuring trustless settlement. 3️⃣ No Congestion Issues: Since Ethereum is only used for periodic state updates rather than every transaction, network congestion does not impact trade speed.

By decoupling execution from settlement, VDEX ensures trades finalize in under 1 millisecond while maintaining Ethereum’s security guarantees.

The Benefits of Sub-Millisecond Finality on Ethereum

✅ No Slippage: Trades execute instantly at the displayed price—no waiting for Ethereum block confirmations. ✅ No MEV or Front-Running: Since orders settle off-chain before being finalized on Ethereum, bots can’t manipulate trades. ✅ Scalability Without Trade Delays: Traders enjoy high-speed execution without worrying about network congestion or gas spikes. ✅ Ethereum Native Trading Without Bottlenecks: Execute trades directly on Ethereum while bypassing slow transaction processing.

For traders who need speed, accuracy, and reliability, VDEX’s sub-millisecond execution on Ethereum provides a CEX-level trading experience without sacrificing decentralization.
