Router Protocol and Silicon L2 Shut Down: How to Get Funds Out

Short answer: In early September 2026 two crypto infrastructure projects announced they are closing. Router Protocol, a cross-chain bridge project, said on September 4–5 that it will cease operations by September 30, 2026 and burn 303,333,198 ROUTE tokens. Silicon, an Ethereum layer 2 linked to the Korean exchange Korbit, stopped accepting bridge deposits on September 2 and gives users until December 31, 2026 to withdraw about $9.75 million still on the network. After those dates, funds left behind may become unrecoverable.

What happened

Router Protocol: closing after four years

Router Protocol built cross-chain infrastructure, including the Nitro bridge, for more than four years. In its shutdown announcement, the team pointed to tight liquidity across Web3, capital moving toward AI, shrinking bridge fee income, high operating costs and activity concentrating on a handful of major chains. It said it had tried commercialisation, technology licensing and a sale, and none produced a sustainable path. Router Chain, the project's own blockchain, had already been wound down in September 2025.

The team will burn 303,333,198 ROUTE from its treasury — more than 30% of the 1 billion maximum supply. The token fell roughly 50% after the news to an all-time low, according to Crypto Briefing. Centralised exchanges were told to set their own delisting and withdrawal schedules, so deadlines for ROUTE holders can differ from venue to venue.

Silicon: an L2 with a four-month exit window

Silicon was an Ethereum layer 2 built with Polygon CDK, connected to Polygon's Agglayer and closely tied to Korbit, one of South Korea's major exchanges. On September 2, 2026 it stopped taking new bridge deposits and opened a withdrawal period that runs until December 31, 2026. After that, the network and its block explorer go offline, and Silicon warned that remaining assets cannot be recovered. Its associated Web3 wallet is being discontinued as well.

When the closure was reported, about $9.75 million in assets was still on the chain. Assets originally bridged from Ethereum can be withdrawn directly. Tokens issued natively on Silicon cannot be bridged back and can only be swapped for something withdrawable while on-chain liquidity lasts — which, Silicon cautioned, may become difficult or impossible as activity fades.

	Router Protocol	Silicon
Type	Cross-chain bridge infrastructure	Ethereum layer 2 (Polygon CDK, Agglayer)
Announced	September 4–5, 2026	Deposits halted September 2, 2026
Final deadline	September 30, 2026	December 31, 2026
Token impact	303,333,198 ROUTE burned (over 30% of max supply); price down ~50%	Native tokens cannot be bridged back to Ethereum
Funds at stake	ROUTE on exchanges; transfers relying on the bridge	~$9.75M: USDC $2.66M, WBTC $2.54M, ETH $2.08M, USDT $1.85M
Exchange handling	Each exchange sets its own delisting timeline	Withdraw via the bridge before the deadline

What happens to your funds when a protocol shuts down?

A shutdown does not delete coins from a blockchain. What disappears is the infrastructure that makes some of those coins usable. The outcome depends on what exactly you hold:

Assets on a base chain in your own wallet (ETH on Ethereum, USDT on Tron) are not affected. The shutdown of a bridge or app does not touch them.
Bridged or wrapped tokens are claims on collateral locked somewhere else. As long as the bridge works, you can redeem them. Once the bridge stops, those tokens can lose their redemption path, and their value then depends on someone else still accepting them.
Assets on a closing layer 2 live inside that network. When the sequencer and nodes shut down, you can no longer send the transactions needed to withdraw. That is why Silicon describes leftovers as unrecoverable.
Native tokens of the closing project — ROUTE, or tokens issued only on Silicon — have no bridge to fall back on. Their only exit is a buyer, and liquidity usually dries up fastest right after the announcement.
Tokens on a centralised exchange follow that exchange's rules. When a token is delisted, there is typically a window to withdraw; after it, the exchange decides what happens to remaining balances.

Withdrawal checklist

Inventory everything. Check every wallet address and exchange account for ROUTE, Silicon-network assets and any tokens you bridged through these services. Portfolio trackers often hide small or unpriced balances, so check the explorer while it still works.
Keep gas on the closing network. Withdrawing from an L2 requires a transaction on that L2, paid in its gas token (ETH on Silicon). Without it, you are stuck.
Use the official bridge and expect more than one step. Rollup withdrawals can involve a waiting period and a final claim transaction on Ethereum. Start early rather than in the last week of December.
Swap native tokens first. If you hold tokens that exist only on the closing chain, convert them to a bridgeable asset while pools still have depth. Every week reduces liquidity.
Check each exchange's own ROUTE deadline. Do not assume September 30 applies to your exchange; its delisting notice sets the real date.
Ignore “migration” and “claim” sites. Shutdowns attract fake portals promising token swaps or compensation. Only use links from the project's official channels, and never sign approvals on unknown sites. Our guide on avoiding crypto scams covers the usual patterns.
Revoke old approvals. Once funds are out, revoke token approvals granted to the closing protocol's contracts. Unmaintained contracts are an easy target.
Land funds somewhere liquid. After withdrawing to Ethereum mainnet, compare where to convert or consolidate — the exchangers list shows current payouts, and the cheapest way to move crypto helps avoid overpaying on network fees.

Why this keeps happening

Both closures reflect the same economics. Bridge fees have compressed, users have concentrated on a few large chains, and small networks struggle to cover infrastructure costs from thin activity. The practical lesson is not to avoid every smaller project, but to treat any funds parked on a niche bridge or L2 as temporary and to follow project announcements closely.

FAQ

When does Router Protocol shut down?

Router Protocol said it will fully cease operations by September 30, 2026. Centralised exchanges set their own delisting and withdrawal timelines for the ROUTE token.

What is the Silicon withdrawal deadline?

Silicon stopped accepting bridge deposits on September 2, 2026 and allows withdrawals until December 31, 2026. After that the network and explorer go offline and remaining assets cannot be recovered.

Can I bridge Silicon-native tokens back to Ethereum?

No. Only assets originally bridged from Ethereum can be withdrawn directly. Tokens issued on Silicon must be swapped into a withdrawable asset while on-chain liquidity is still available.

Are my coins lost if a bridge I used shuts down?

Coins that have already arrived on their destination chain as native assets are unaffected. The risk applies to wrapped or bridged tokens that depend on the bridge for redemption, and to funds still on a network that is being switched off.
