Silicon Network Withdrawal Window Opens Ahead of Permanent Shutdown

TLDR

• Silicon Network stopped new deposits and began shutting down on Sept. 2, 2026.
• Users have until Dec. 31, 2026 to withdraw remaining funds.
• About $9.75 million in assets is still on the network.
• Withdrawal paths differ by token, with liquidity limited for assets issued directly on the chain.
• Korbit’s Web3 Wallet, built on Silicon, is also being discontinued.

Silicon Network, an Ethereum layer 2 chain, has begun shutting down. The network stopped accepting new bridge deposits on Sept. 2, 2026.

The shutdown starts a withdrawal period. Users now have until Dec. 31, 2026 to move their funds off the chain.

Silicon warned that its explorer and network will close for good after the deadline. Any assets left on the chain after that point cannot be recovered.

The network was built using Polygon’s CDK framework. It connected to Agglayer and was closely tied to Korbit, a major South Korean crypto exchange.

Withdrawal Window and Deadline

Silicon said it operates as a non-custodial service. That means each user is responsible for managing and withdrawing their own assets before the network closes.

The company stated that assets originally bridged from Ethereum can be sent back to the mainnet during the withdrawal window. External wallet holders need to start this process themselves.

Users must also keep enough ETH on hand to cover gas fees. The withdrawal has to be finalized before the Dec. 31 cutoff or the funds could be lost.

Korbit’s Web3 Wallet also ran on the Silicon network. That product gave exchange customers access to decentralized apps and is now being shut down less than two years after it launched.

Assets Still Stuck on the Network

Data from L2Beat shows Silicon still holds close to $9.75 million in assets. That total is spread across several different tokens.

USDC makes up the largest share at $2.66 million. WBTC follows at $2.54 million.

ETH holdings on the network total $2.08 million. USDT accounts for another $1.85 million.

How easily each of these tokens can leave the network depends on what a user holds. Assets that came directly from Ethereum have a clearer path back to the mainnet.

Tokens issued directly on Silicon face a different situation. Their ability to exit relies on the network’s remaining liquidity, which is shrinking as the shutdown approaches.

This closure adds to a pattern of smaller Ethereum layer 2 networks shutting down after failing to sustain enough activity. Silicon had aimed to bridge Korean exchange users into the broader Ethereum ecosystem.

The network launched with backing from Korbit as part of a push to connect centralized exchange customers with onchain applications. That effort is now ending less than two years after it began.

Users who still hold funds on Silicon have until the end of the year to act. After Dec. 31, the network and its explorer will go offline for good.
