# Why Functor Network?

Web3’s path to programmable, cross‑chain finance is blocked by one root cause: **signer fragmentation**.

**Smart‑account wallets** improve UX, yet each new chain gives the same user a different signer with different permissions. Those signers are **not composable** across chains, which breaks key management, creates inconsistent approvals, and blocks interoperable automation.

Functor Network is building a **keystore layer**, a **minimal zk-rollup** of signers that any **ERC‑7579 validator module** can query. By eliminating fragmented signer state while preserving **self‑custody**, Functor provides the **uniform authorization layer** smart accounts need to operate seamlessly across the ecosystem.

* **One signer** set usable on any new chain at wallet creation
* A single, **Ethereum‑anchored root** for **global key revocation, recovery**, and **programmable** **permissions**
* **Cross‑chain operations** that execute under the **same authorization rules** with **no extra approvals**

### Problem 1: Signer Fragmentation Crisis <a href="#problem-1-signer-fragmentation-crisis" id="problem-1-signer-fragmentation-crisis"></a>

Smart accounts are on the rise, but every chain and every account instance adds another **isolated signer set**.

* **Permissions drift** across L2s and apps, which leads to inconsistent security posture
* **Global revocation and recovery** are hard or impossible to enforce across environments
* **Operational overhead** multiplies with each new chain, degrading UX and increasing risk

Without a **dedicated signing layer**, Ethereum cannot safely scale to multichain usage or support **autonomous systems** with **consistent policy**.

***

### Problem 2: Interoperable User Experience Gap <a href="#problem-2-interoperable-user-experience-gap" id="problem-2-interoperable-user-experience-gap"></a>

What users want is simple. **One identity. One set of permissions.** Predictable approvals and recovery that work the same everywhere. Today they get the opposite.

* Each L2 and each deployment creates a **separate signer** with different permissions
* **Approvals and access controls do not travel** with the user
* **Recovery and revocation differ** by chain, which leads to **blind signing** and uncertainty

Functor Network closes this gap with a **keystore layer** that smart accounts can query directly.

* **Minimal zk rollup of signers** that **ERC‑7579** validator modules can use for authorization
* **Wallet creation** with a **single signer set** that is instantly usable on any new chain
* **Security anchored to Ethereum** for **global revocation**, **recovery**, and **programmable permissions**
* **Multichain automation** where actions follow the **same rules across chains**, with **no extra approvals**

This establishes the **interoperable UX layer** that makes smart accounts truly portable and safe.

### Problem 3: Cross-Chain Automation Barriers <a href="#problem-3-cross-chain-automation-barriers" id="problem-3-cross-chain-automation-barriers"></a>

Automation fails without **consistent authorization**. Strategies and agents need to act across chains under one policy. Today that is not possible.

* Agents cannot safely hold **private keys**, yet they need **signing capability**
* Execution rules and approvals differ per chain, which blocks coordinated strategies
* **Fragmented capital** persists. **$200B+ in DeFi** cannot move programmatically under one set of permissions

**Uniform authorization** is the prerequisite. With a **keystore layer anchored to Ethereum**, the **same policy everywhere** can govern activity. Cross‑chain operations can execute programmatically, under **consistent rules**, without manual coordination or new approvals at every step.

***

### Why now?

* **L2 proliferation** and **smart‑account adoption** are accelerating, which magnifies signer fragmentation
* **ERC‑7579** validator modules and **Pectra** move smart accounts toward first‑class status, creating the interface and momentum for a shared signing layer
* The rise of **AI‑driven** and **institutional** workflows creates immediate demand for secure, programmable, **self‑custodial authorization** that spans chains
* Industry efforts such as **Trillion Dollar Security** underscore UX in **key management** as a core blocker, reinforcing the need for foundational keystore infrastructure

***

### Potential Ecosystem Benefit

A **one‑signer network** for infinite chains removes the **key‑management bottleneck** and upgrades UX and security at the same time.

* **Chain‑agnostic wallet creation and recovery**
* **Consistent approvals** and **permission management** across L2s
* **Reduced blind signing** and clearer transaction intent
* **Composable authorization** that enables safe, **cross‑chain automation**
