Safe.eth Re-poster

Our newest Safe{Research} highlight dives into the concept of self-managed cosigners. Traditionally, a cosigner functions as an impartial reviewer that evaluates your transactions prior to completion. You might already be familiar with this type of monitoring through existing solutions provided by @blockaid_ and @HypernativeLabs Guardian. In contrast, our study looks at an alternative where you hold the reins. You dictate the rules and confirm the evaluations yourself, relying entirely on Safe Guards to execute the necessary enforcement directly onchain. Read the full piece below to discover all the details.

Taking direct ownership is a clear positive sign that will always be superior to the concerning practice of delegating that ownership to someone else.

Embracing self-custody transforms the ideal of true personal independence into a highly actionable reality.

It is my absolute conviction that eventually, everyone is going to utilize @safe. You can count on this prediction coming true.

Safe{Research} under the microscope 🔬

With its plug-and-play, modular framework, the Policy Engine facilitates the concurrent use of multiple guards. In this setup, Fiducia is responsible for managing functions and addresses, whereas Guardrail takes care of delegate calls.

This architecture provides verifiable, auditable control onchain by applying a deny-by-default approach to create fine-grained policies.

We are turning the Safe{Research} spotlight onto Fiducia, which takes its name from the Latin word for trust. As a dedicated Safe Guard, this tool empowers users to establish strict parameters, including the management of allowlists and blocklists for addresses as well as restrictions at the function level. Additionally, it allows for the enforcement of mandatory cosigner approvals and operation-specific time delays. Conceptually, this acts as a set of programmable trust guidelines that are validated onchain prior to the execution of any transaction. Read the full post below.

Just Use Safe.

High-stakes actions, such as authorizing the launch of nuclear missiles or deleting a production database, should arguably require approval from multiple people. Sending $10M on-chain belongs on that list as well. Yet, uniquely among these examples, such a massive transfer is commonly executed using only a single signature. Just Use Safe.

One common obstacle is collecting signatures from multiple signers without requiring each individual to pay gas fees. We addressed this by establishing Harbour as a native ERC-4337 account. Through the nonce functionality of the EntryPoint, every signer uses their distinct address as the key. This enables parallel submissions and prevents collisions, effectively removing the need to juggle gas. All p2p messaging between signers and validators is managed by Waku.

Please remember that self custody should be your top priority.

In 2006, "owning your data" sounded paranoid.
In 2016, "owning your money" sounded fringe.
In 2026, "owning your identity" sounds early.
The pattern isn't hard to see.
