Forta Firewall Now Available on Gelato Marketplace: Raising the Standard for Rollup Transaction Screening

The Forta Foundation is proud to announce that Forta Firewall is now integrated into the Gelato Marketplace, making advanced, real-time transaction screening available to Rollups built on Gelato. With this integration, rollup developers and users gain a critical new layer of protection against exploits and compliance risks without sacrificing speed or user experience. 

Sequencer Level Integration to Filter Transactions

Unlike traditional tools that react after an attack, Forta Firewall screens and blocks high-risk transactions before they reach the sequencer. Powered by a machine learning model trained on years of blockchain data (including all types of transactions) Firewall detects malicious behavior in real-time.

High-risk transactions are flagged and filtered out immediately, ensuring they never make it into a block. This proactive approach protects user funds and helps rollup ecosystems grow more securely and sustainably.

A Seamless Path to Protection

Rollups can now request Forta Firewall protection directly through the Gelato Marketplace, with no custom integration work required. Once enabled, transactions are automatically routed through Forta Firewall’s screening engine before reaching the sequencer.

This real-time check adds an essential security layer with minimal latency and zero disruption to the user experience. Developers can focus on building and scaling their applications, while users benefit from stronger guarantees of safety and compliance.

Security and Compliance, Together

Forta Firewall not only also supports exploit protection, but also other modules like compliance screening or scam prevention. Rollups can automatically block transactions involving sanctioned addresses, stop phishing campaigns, and prevent other malicious activity such as rug pulls.

By embedding both security and compliance transaction screening at the infrastructure level, Gelato and Forta are setting a new benchmark for safe, scalable and institutional grade rollup ecosystems.

How It Works

When a transaction is signed and broadcast by a user, it is first analyzed by Forta Firewall. Using patterns learned from real blockchain data, the AI model assigns a risk score to the transaction:

• 🟢 Low-risk transactions proceed to the sequencer without delay.
• 🛑 High-risk transactions are filtered out before they can be included in a block.

This screening happens automatically, without requiring any additional action or trust from the user. Furthermore, the system supports on-chain attestations and is carefully designed with censorship-aware principles in mind.
