Our MEV-Resistant Sequencer Capabilities
We architect and deploy custom, high-performance sequencers designed to protect your users from front-running and sandwich attacks, ensuring fair transaction ordering and predictable costs.
01
Fair Ordering & Commit-Reveal Schemes
We implement cryptographic commit-reveal protocols and fair ordering algorithms (e.g., FCFS, time-boost) to neutralize value extraction from public mempools. This protects your users and guarantees transaction finality is based on submission time, not gas price.

< 2s
Reveal Latency
02
Encrypted Mempool Architecture
Our sequencers operate with private, encrypted mempools. Transaction details remain hidden until inclusion in a block, eliminating the visibility that predatory bots rely on for MEV extraction.

Zero Leak
Data Policy
03
Custom Rule Engine & PBS Integration
We build configurable rule engines for transaction filtering and integrate with Proposer-Builder Separation (PBS) frameworks. This allows you to define acceptable MEV (e.g., arbitrage) while blocking harmful strategies, aligning incentives with your protocol's goals.

COMPETITIVE ADVANTAGE
Why Build an MEV-Resistant L2
MEV extraction is a critical vulnerability that erodes user trust and undermines protocol economics. Building with MEV resistance from day one is a foundational security and business decision.
01
Protect User Value
Eliminate front-running and sandwich attacks to ensure fair transaction ordering. This directly protects your users' swap execution and reduces slippage, building long-term loyalty and activity.

Transaction Ordering
02
Secure Protocol Economics
Prevent value leakage from your DeFi ecosystem. MEV-resistant sequencing ensures arbitrage profits and liquidation fees are captured by your protocol and its stakers, not predatory bots.
