FormaChain Mainnet Shutdown: What TIA and NFT Users Must Do?

FormaChain Mainnet Shutdown: Withdrawal, TIA Migration and NFT Claims

The FormaChain Mainnet shutdown is expected at block 34,567,890, which the team estimates will happen around November 5, 2026. 

Users have about two weeks to withdraw funds before the chain halts. After that, remaining TIA moves to the Eden network, while Modularium NFTs move to Ethereum. The two paths work differently, so holders should read each step and act early.

At a Glance: FormaChain Mainnet Shutdown Date and Migration Details

These facts come from the official Forma announcement on X. The November 5 date is an estimate, so treat it as a guide and not a promise. Forma has not shared an exact withdrawal cutoff time.

Why is FormaChain Shutting Down After a Sustainability Review?

Forma is a Celestia-based sovereign rollup built through Astria. It focuses on on-chain creator tools and NFTs, mainly through the Modularium ecosystem.

The FormaChain Mainnet shutdown follows a sustainability announcement the team made in July 2026. Forma has not shared detailed financial reasons, so this article does not guess at them. There is also no sign that assets will simply vanish when the chain stops. What happens to each asset depends on the migration plans the team has announced, and those plans differ for TIA and for NFTs.

FormaChain Mainnet Timeline: What Happens Before and After November 5?

• July 2026: Forma announces its sustainability concerns and its transition plans.

• Now: Users should prepare and withdraw funds before the network reaches the shutdown block.

• Around November 5: The chain is expected to halt at block 34,567,890.

• After the halt: Forma takes a snapshot. Remaining TIA tokens are migrated to Eden, and Modularium NFTs move to Ethereum. This may take several days.

The steps after the halt depend on finishing each migration and publishing its instructions. It will announce when each migration is complete.

What Happens to TIA After FormaChain Mainnet Stops?

Forma plans to take a snapshot after the shutdown and migrate any remaining TIA to Eden. Both Eden and Forma are EVM chains. That means you can use the same wallet address on both networks.

Once the migration is complete, you should be able to withdraw your migrated assets from Eden. Keep in mind that a shared address does not mean your funds appear instantly. 

It also does not prove every asset will transfer on its own. Wait for the official completion notice and the instructions that go with it. Withdrawing before the halt remains the safest route, because it removes your dependence on the later migration.

How Can Modularium NFT Holders Claim Their Assets on Ethereum?

NFT holders face a different process than TIA holders. Modularium will live on Ethereum, and all of its NFT assets will migrate to Ethereum L1.

The announcement is clear on one point. NFTs will not be airdropped to holders automatically. Instead, holders must claim them through the relaunched Modularium website. Forma has not yet published the full claim steps, and it says more details will arrive in the coming weeks.

Since the FormaChain Mainnet will already be offline by then, scammers may try to take advantage of the confusion. Check that you are on the official Modularium website before you connect a wallet. Do not sign a transaction or pay a claim fee unless the official channels have confirmed it.

What Should Users Do Before the FormaChain Mainnet Shutdown?

Use this short checklist to stay ahead of the deadline:

• Check your balances and withdraw funds before the network halts.

• Confirm the correct network, destination address and transaction requirements.

• Keep your wallet and its recovery phrase secure at all times.

• Follow the official chain and Modularium channels for updates.

• Do not assume the TIA migration and the NFT claim will happen at the same time.

• Ignore unofficial links and unexpected direct messages.

• Never share your seed phrase or private keys with anyone.

No one can promise that every asset will be recoverable in every situation. Follow only the instructions the project has confirmed.

Conclusion: What Forma Holders Need to Know Before the Network Halts

Three points matter most. Withdraw your funds before the estimated November 5 shutdown. Watch how TIA migrates to Eden. Prepare to claim your Modularium NFTs by hand on Ethereum. Final deadlines and detailed steps will come from Forma, so rely on its official updates and not on rumors.
