How White Hat hackers help secure DeFi

1inch has joined the SEAL Whitehat Safe Harbor Agreement, enabling whitehat hackers to step in effectively when needed. 

In DeFi, attacks don’t happen slowly. They unfold in real time. Funds move in minutes. And in that narrow window, the difference between loss and recovery often comes down to whether someone is willing - and able - to act immediately. That “someone” is often a white hat hacker.

What are white hats and what’s their role in DeFi?

White hat hackers are security researchers who identify vulnerabilities in protocols - not to exploit them, but to prevent damage.

In traditional software, their role is relatively straightforward:

• find a bug
• report it
• receive a bounty

In DeFi, the stakes are higher.

Protocols are live, permissionless and often hold hundreds of millions in user funds. When an exploit begins, there may be no time to report and wait. The only way to stop the attack may be to act immediately - interacting directly with smart contracts, moving funds, or front-running the attacker.

In other words, white hats may need to behave like attackers in order to stop one.

What is SEAL?

Security Alliance (SEAL) is a crypto security nonprofit founded by samczsun, one of the most respected figures in the DeFi security space.

The organization focuses on improving how the industry responds to threats in real time. Its initiatives include:

• SEAL 911 - an emergency response hotline for active exploits
• SEAL Intel - a threat intelligence sharing network
• SEAL Frameworks - open-source security playbooks
• SEAL Certifications - certifications for operational security

The goal is to move beyond static security and toward coordinated, rapid response.

What is the Safe Harbor Agreement?

The Safe Harbor Agreement is designed to solve a very specific problem: enabling white hats to act during active exploits without fear of legal consequences.

At its core, it is a simple commitment from a protocol:

If you step in to protect funds during a live exploit and follow the rules, we will not pursue legal action against you.

This creates a defined framework for emergency intervention, where speed is critical and traditional processes are too slow.

How the agreement works in practice

The Safe Harbor Agreement establishes clear boundaries for white hat action.

White hats are allowed to intervene - but only under strict conditions.

They can act only during an active exploit, not for general testing or vulnerability research. The agreement is explicitly limited to situations where funds are at immediate risk.

They must contact the protocol’s security team as soon as intervention begins, ensuring coordination and transparency. For 1inch, the designated contact is 1inch Security ([email protected]).

Any funds recovered must be returned in full within 72 hours to a designated recovery address designated in the adoption. This ensures that rescued assets are secured quickly and do not become a secondary risk.

White hats are also incentivized. Successful interventions are rewarded with a bounty - typically a percentage of the recovered funds, capped at a predefined amount.

At the same time, the agreement provides legal protection, reducing the risk of liability for good-faith actions taken under these conditions.

Importantly, researchers can remain pseudonymous, identifying themselves to the protocol without public disclosure. Bounty payment is subject to sanctions and AML screening under 1inch’s adopted terms.

What the agreement does - and does not do

The Safe Harbor Agreement is not a guarantee of recovery.

It does not:

• ensure that funds can be saved
• bind regulators or third parties
• replace traditional security practices

What it does is remove a key barrier to action.

It gives white hats the confidence to step in when it matters most—during the narrow window where intervention can still make a difference.

From passive security to active defense

DeFi security has traditionally focused on prevention: audits, bug bounties, and responsible disclosure.

But as exploits become more sophisticated, prevention alone is not enough.

The industry is moving toward active defense:

• real-time monitoring
• coordinated response
• rapid intervention

White hats are central to this shift. They are often the first to detect anomalies and the only actors capable of reacting fast enough to mitigate damage.

The Safe Harbor model formalizes their role—not as external observers, but as participants in emergency response.

A growing industry standard

The Safe Harbor Agreement has already been adopted by leading protocols, including Uniswap, zkSync, Pendle, PancakeSwap and Balancer.

Its adoption reflects a broader recognition: DeFi needs mechanisms that enable action, not just analysis.

As protocols become more complex and interconnected, the ability to respond quickly to exploits becomes a critical layer of security.

Building safer DeFi

By adopting the SEAL Whitehat Safe Harbor Agreement, 1inch is aligning with this emerging standard. The adoption was approved through 1inch DAO governance.

The agreement provides clear guidelines for action, increases the protection of user funds and demonstrates a commitment to proactive security - empowering white hats to act when it matters most.  The covered protocols (including the 1inch Aqua Protocol), the designated recovery addresses and the bounty terms are set out in 1inch’s adoption record (1IP-104).
