# Nodle expands to Ethereum: Building bridges across the Web3 ecosystem

By [Nodle Network](https://paragraph.com/@nodle) · 2025-10-29

The Nodle Network has reached a major milestone — the first NODL mint on Ethereum Layer 1 (L1) has been completed, officially activating the new bridge between ZKsync (L2) and Ethereum Mainnet (L1). This pivotal moment expands NODL’s reach and interoperability, allowing users and institutions to engage with a broader spectrum of protocols, liquidity venues, and DeFi applications across Web3.

**Why Build a Bridge to Ethereum L1**
-------------------------------------

As [Nodle](https://www.nodle.com/) continues to grow within the [ZKsync ecosystem](https://www.zksync.io/ecosystem), interoperability is at the heart of its strategy. ZKsync provides the performance, scalability and developer flexibility needed to power Nodle’s token economy. With the recent [Atlas Upgrade](https://zksync.mirror.xyz/XrlYJN9SUbOtRn9nyqrfPyaAqot--PlUcnSRK_OF1Bs), ZKsync introduced major advancements - including **near real-time finality**, multi-VM compatibility, and **cross-chain coordination** through the ZK Stack. Together, these features enable a seamless network of sovereign chains anchored by Ethereum’s security and liquidity.

In this context, the Ethereum bridge **acts as an anchor extension**, designed not to replace ZKsync but to **complement** it. The bridge empowers users and enterprises to access established DeFi protocols, institutional liquidity, and on-chain services native to Ethereum - all while **maintaining ZKsync as the operational home** of the NODL token.

* * *

**How the Bridge Works**
------------------------

The bridge introduces a **two-way interoperability** mechanism between ZKsync’s Layer 2 and Ethereum’s Layer 1.

It operates through two **synchronized** NODL representations:

*   NODL (L2) on ZKsync — the **canonical version** of the token, where **all minting** originates.
    
*   NODL (L1) on Ethereum — an ERC-20 representation **minted and burned** by the bridge contracts.
    

The bridge ensures **one-to-one parity** through a burn-and-mint process:

*   When tokens **move** from L2 to L1, ZKsync NODL is **locked** and the same amount is **minted** as ERC-20 NODL on Ethereum.
    
*   When tokens **return**, the L1 tokens are **burned**, and the equivalent L2 amount is **released**.
    

This model guarantees a synchronized supply across **both networks**, preserving integrity and preventing duplication.

*   When sending NODL from zkSync to Ethereum, the transfer may take **up to 24 hours** before tokens become claimable on L1. This waiting period corresponds to the “finalize” step, which occurs once zkSync **publishes its proofs** on Ethereum.
    
*   In contrast, transfers from Ethereum to zkSync are typically **much faster** — usually within an hour or less, based on network conditions and zkSync’s confirmation speed.

**Important note for users**
----------------------------

The Nodle–Ethereum bridge is fully **live, secure, and functional**. Users can already transfer their NODL tokens between zkSync Era and Ethereum Layer 1 using the available contract interfaces.

However, for a smoother experience, the Nodle team is **currently developing** a dedicated, user-friendly interface that will be integrated directly into **Nodle’s Portal** at [zkclient.nodle.com](https://zkclient.nodle.com/)

This upcoming UI will simplify deposits, withdrawals and status tracking between layers - ensuring that users can interact with the bridge **quickly**, **securely** and with **full transparency**.

A **forthcoming blog post** will delve into the Portal, upcoming integrations and use cases, once the UI is complete and **potential** strategic partnerships have been thoroughly examined.

* * *

**Network Continuity and Security**
-----------------------------------

The deployment of the Nodle bridge does not signify a change in networks. ZKsync remains the **primary minter** and **operational layer** for the NODL token. Ethereum acts as an **extension** that increases flexibility and reach, not as a new base chain.

To ensure reliability, the [bridge smart contracts](https://github.com/ResonanceCybersecurity/audits/blob/781e6df3ab7aa4c1f7f6b531b0ce86e6bc99d1db/Solidity%20Smart%20Contract%20Audits/Audit_Report_NODL-BRD_FINAL_21.pdf) were **audited** by [Resonance Security](https://www.resonance.security/) in September 2025. The audit verified the safety of the mint/burn mechanisms, ownership controls and cross-chain verification logic - ensuring the bridge meets modern security and protocol integrity standards.

* * *

**Unlocking new opportunities**
-------------------------------

The integration with Ethereum unlocks new future **potential** for the NODL asset:

*   **DeFi Access**: Inclusion in liquidity pools, yield platforms, and staking protocols across Ethereum’s ecosystem.
    
*   **Exchange Listings**: Easier compatibility with decentralized and centralized exchanges using ERC-20 standards.
    
*   **Cross-Ecosystem Interoperability**: Direct access to Ethereum-aligned dApps, bridges, and Web3 infrastructure.
    
*   **Institutional Reach**: A smoother path for custody, treasury, and payment integrations across multiple chains.
    

These capabilities collectively **enhance** the token’s presence and utility across networks, strengthening Nodle’s position as a **truly interoperable** project.

* * *

**A Milestone Moment**
----------------------

As announced by **Micha Benoliel**, Nodle’s CEO, on X, the first official NODL mint on Ethereum L1 marks the live activation of the bridge and confirms that all systems are operational. The event demonstrates Nodle’s commitment to evolving from a single-network token into a **multi-chain digital asset** that thrives in both **ZKsync** and **Ethereum** environments.

**The Road Ahead**
------------------

By bridging ZKsync and Ethereum, Nodle reinforces its mission to connect the **physical** and **digital** worlds through a decentralized trust network — now extended into the broader DeFi landscape. With this step, the NODL token gains more **flexibility**, **visibility** and **global utility** positioning it to grow alongside the rapidly expanding ZK Stack ecosystem and the Ethereum network.

This is more than just a bridge.It’s the next connection in Nodle’s journey toward an open, interoperable and connected Web3 future.
