Imagine:

One day you wake up and your protocol got exploited …maybe you heard of ERC-7265 as attempt to end that quite real nightmare.

With TurtleShell we are aiming to give every Smart Contract holding Assets the necessary bolster to prevent unintended outflow.

on-chain realtime hack prevention we are building on-chain firewalls What is an On-Chain Smart Contract Firewall? Smart contract hacks have been plaguing DeFi protocols, bridges, and more.

Today, in order to defend themselves, protocols perform audits, open bug bounties, and implement monitoring.

All of these steps are absolutely crucial. Nevertheless, whenever a vulnerability is discovered by an attacker, most exploits can drain funds in a very short period of time, sometimes even within a single transaction. To prevent these hacks from happening, we need an on-chain tool.

You can think of the Smart Contract Firewall as an additional layer of security for DeFi protocols.

Our Firewall is a set of Solidity Smart Contracts that allow you to:

Define critical parameters for your protocol (e.g., TVL) and track these parameters over time.

Detect that a transaction (or multiple) is causing the protocol to operate outside its normal activity (e.g., unusual liquidity outflow, indicative of a potential hack happening).

Implement a set of protective measures, including transaction blocking, protocol pausing, fund freezing, or controlled fund withdrawal, before the transaction is committed and funds exit the protocol.

The Firewall provides a way to detect abnormal changes in your protocol directly on-chain, that could be indicative of a hack. That means that you can act upon abnormal activity, whenever it occurs, directly on the blockchain.
