Moonbeam halted all user transactions on Aug. 1 as its Polkadot network winds down ahead of a Base relaunch. With 75.17 percent of GLMR supply outside the direct migration bridge, late holders face discretionary recovery through an email helpdesk with no public guarantee of fund recovery.
Moonbeam halted all user transactions Aug. 1, with 75.17 percent of GLMR supply outside the migration bridge as Polkadot parachain winds down for Base relaunch.
The migration portal now directs late holders to email the helpdesk for individual review, with no public guarantee that every balance can be recovered, according to Moonbeam's published wind-down schedule.
At 20:20 UTC on July 31, less than four hours before the cutoff, the migration contract held about 308.183 million GLMR against total issuance of 1.241 billion GLMR, putting direct-bridge uptake at 24.83 percent. The remaining supply spans free holdings, exchange custody, staking, treasury, and other balance categories.
The network entered maintenance mode at 00:00 UTC on Aug. 1 and began rejecting transactions, though Moonscan said blocks would continue during the operational wind-down. For staking and crowdloan balances frozen at the cutoff, Moonbeam said it would honor them on Base if holders met account-signature and snapshot requirements — but its public guidance did not extend the same commitment to governance locks, DeFi positions, or unclaimed rewards.
Before the deadline, Moonbeam told users to withdraw funds from liquidity pools, lending markets, staking, crowdloans, governance locks, and other protocols where possible before bridging. The project's July 3 announcement warned that funds left deployed in on-chain protocols may become inaccessible after the network wound down. Its support guidance said the bridge processed only free balances.
The official migration locked GLMR on Moonbeam and released the same amount from a reserve minted in advance on Base, sending tokens to the same user address at a 1:1 rate. Exchange handling varied: KuCoin said it would automatically convert GLMR balances held on its platform at 1:1, while Bybit announced its GLMR network migration and cutover schedule separately. Exchange-held balances followed each venue's process rather than the direct migration-contract route, so the contract ratio cannot measure stranded or at-risk supply. The snapshot tracks direct bridge use, not stranded supply, while self-custodied tokens and protocol positions face separate action paths.
The discretionary nature of post-cutoff recovery creates material risk for GLMR holders who missed the window. With no universal late bridge published, individual review by email helpdesk means recovery outcomes could vary by case, potentially undermining confidence in the Moonbeam migration process and the broader Polkadot ecosystem's parachain transition model. The outcome could also draw regulatory attention to how user funds are handled during network migrations, particularly for projects that wind down without a guaranteed recovery mechanism.
