Moonbeam, once the crown jewel of Polkadot’s parachain ecosystem, is pulling the plug. The network will cease operations on July 31, 2026, and every user with funds parked on the chain, whether through Moonwell, Wormhole, or any other protocol, has a hard deadline to get their money out.
What’s happening and why it matters
Wormhole, the cross-chain interoperability protocol that enables token transfers across blockchains, has issued a direct warning to its users. Any assets bridged to Moonbeam via Wormhole must be withdrawn and transferred to other networks before the shutdown date. Once the parachain winds down, Wormhole contributors will not be able to assist with any stuck assets.
Moonwell, the decentralized lending protocol that operates on Moonbeam, is taking the threat seriously. The protocol has introduced governance proposal MIP-M45, which aims to halt all new supply and borrowing activity on Moonbeam ahead of the parachain’s closure. The proposal also calls for withdrawing reserves from various markets on the chain.
The assets affected on Moonwell include GLMR, xcDOT, USDC, FRAX, and ETH. Users with open lending or borrowing positions on the protocol’s Moonbeam deployment need to close them manually. There is no automatic migration, no safety net, no do-over.
Moonwell’s strategic retreat from Polkadot
Moonwell deprecated its Moonriver deployment on January 29, 2026. Moonriver is Kusama’s equivalent of what Moonbeam is to Polkadot, essentially a canary network that served as a testing ground.
Then, on May 21, 2026, Moonwell migrated its governance from Moonbeam to the Ethereum mainnet. MIP-M45 is the final chapter of that migration story. By halting all new lending and borrowing on Moonbeam, the protocol is effectively telling its remaining users: we’re leaving, and you should too.
The GLMR token migration to Base
For holders of GLMR, Moonbeam’s native token, there’s a specific path forward. The token is scheduled to migrate on a 1:1 basis to an ERC-20 token on Base, Coinbase’s Layer-2 network built on Ethereum’s OP Stack.
A migration bridge has been set up for this purpose, but it comes with the same hard deadline. The bridge is expected to remain operational only until July 31, 2026. After that, any GLMR still sitting on Moonbeam becomes unrecoverable.
Moonbeam was the first parachain on Polkadot to support full Ethereum-compatible smart contracts, having launched on January 11, 2022.
What investors and users should do now
The immediate priority is straightforward: if you have any assets on Moonbeam, move them. This applies whether you’re using Moonwell, Wormhole, or any other protocol deployed on the chain.
For Moonwell users specifically, the steps involve closing any open lending or borrowing positions on the Moonbeam deployment. For GLMR holders, the 1:1 migration to an ERC-20 token on Base needs to happen before the bridge closes on July 31, 2026.
