Moonbeam Network’s July 31, 2026 ending of its Polkadot parachain is the answer to “Moonbeam migration”: announced by Moonbeam on July 3, the project shifted GLMR to Base and told users to withdraw DeFi positions before the old chain wound down.
Moonbeam migration: what actually happened?
Moonbeam did not simply change. It ended the running phase of its Polkadot-based network and began a new Base-based direction focused on AI-agent communication and settlement. GLMR holders were instructed to migrate their tokens 1:1 into a Base ERC-20 token.
Who was impacted?
The overlooked impact fell on DeFi users, not just token holders. Moonbeam specifically warned users to withdraw liquidity positions, lending deposits, staking contracts and other funds from protocols deployed on the old chain. Positions left behind could become hard to access after the shutdown.
An ERC-20 is a common standard for replaceable tokens on Ethereum-compatible networks. The new GLMR format therefore changes the asset’s network environment and contract address, even though the migration ratio remained 1:1.
What should users do now?
- Check whether funds remain on Moonbeam, including positions provided to DeFi protocols.
- Confirm the destination chain, token contract and liquidity before moving assets.
- For assets supported by the relevant networks, compare working cross-chain options such as gnosis bridge, while verifying support and transaction details independently.
What does Moonbeam migration change for DeFi?
It removes Moonbeam’s old deployment environment from the user’s network map. Applications, liquidity pools and infrastructure providers must now publish clear migration guidance; users should treat old-chain balances as an operational recovery problem, not as ordinary long-term holdings.
