Moonbeam Network — one of Polkadot's earliest and biggest parachains — is fully leaving the ecosystem after ~4 years and migrating its GLMR token to Base, Coinbase's Ethereum L2.

Holders have until July 31 to bridge GLMR 1:1 to a new ERC-20 on Base through a dedicated migration portal. Centralized exchanges are expected to swap custodied balances automatically.

The move ends a four-year run on Polkadot and repositions Moonbeam inside the Ethereum ecosystem as a decentralized network for AI-agent infrastructure and communications.
