Zerion Is Shutting Down Zero Network After 18 Months — What Users Need to Do Now

In effect, the team decided that enabling access to on‑chain activity across many networks—through its wallet and APIs—offered a clearer product direction than maintaining its own Layer 2.

The move also reflects a broader economic reality in the Ethereum ecosystem: operating a Layer 2 chain has become extremely competitive, with only a few networks capturing the majority of users, liquidity, and transaction activity.

Earlier Technical Issues in 2026

Operational stability was also tested earlier in the year.

In late 2025 and early 2026, Zero Network experienced a prolonged outage in which the chain stopped producing blocks for more than three weeks.

During that period, the Zerion team worked with infrastructure partners including Caldera and zkSync to restore the network. Block production eventually resumed in mid‑January 2026, and the team said that user funds remained safe throughout the incident.

Data observed by monitoring tools showed extended periods without state updates or proof submissions during the outage, highlighting the severity of the disruption.

While the exact technical root cause was not publicly detailed in full, the episode underscored the operational complexity of running a rollup‑based blockchain.

What Users Must Do Before the Shutdown

The network is now entering a wind‑down phase.

Users who still hold assets on Zero Network must move them off the chain before July 31, 2026, when the network is expected to cease operations and stop producing blocks.

Key steps for users:

• Withdraw or bridge all ETH, tokens, and NFTs from Zero Network.
• Send assets to Ethereum mainnet or another supported blockchain.
• Complete withdrawals before the shutdown deadline.

Cross‑chain deposits into Zero Network have already been disabled as part of the shutdown process, leaving withdrawals as the remaining action for users.

Bridging out can typically be done using Zerion’s integrated bridge interface or the network’s canonical bridge tools.

Why This Reflects a Bigger L2 Shake‑Out

The end of Zero Network is part of a broader consolidation wave in Ethereum’s Layer 2 landscape.

Over the past two years, dozens of rollups launched to compete for developers and liquidity. But activity has increasingly concentrated in a small number of dominant ecosystems such as Base, Arbitrum, and Optimism. Some estimates suggest these networks process close to 90% of Layer 2 transactions.

At the same time, Ethereum upgrades such as proto‑danksharding have dramatically reduced data costs for rollups, which intensified fee competition and squeezed the economics of operating smaller chains.

In this environment, smaller or less differentiated Layer 2 projects often struggle to maintain sustainable usage or revenue.

Zero Network’s shutdown therefore illustrates a broader trend: while Ethereum scaling has expanded dramatically, the market for operating independent Layer 2 chains is consolidating quickly around a few dominant platforms.

The Practical Takeaway

For users, the most important step is straightforward: move assets off Zero Network well before the July 31, 2026 deadline.

After that point, once block production stops, interacting with the chain could become difficult or impossible.

For the broader ecosystem, the shutdown is another reminder that infrastructure experiments in crypto often evolve quickly—and that the long tail of Layer 2 networks may continue to shrink as competition intensifies.
