Our FSS Oracle Integration Capabilities
We architect and deploy secure, low-latency Fair Sequencing Service (FSS) oracle integrations that guarantee transaction order integrity and protect your DeFi protocols from front-running and MEV attacks.
01
Custom FSS Adapter Development
We build custom smart contract adapters to connect your protocol's core logic with leading FSS providers like Chainlink FSS or Shutter Network. Our adapters handle order commitment, submission, and result verification with minimal gas overhead.

GUARANTEED RESULTS
Business Outcomes for Your Protocol
Integrating Chainscore's Fair Sequencing Service Oracle delivers measurable improvements to your protocol's security, user experience, and operational efficiency. These are the concrete outcomes you can expect.
01
Eliminate Front-Running & MEV
Our oracle provides a verifiably fair transaction ordering consensus, protecting your users from sandwich attacks and predatory arbitrage bots. This builds trust and ensures equitable execution for all participants.
