Binance to End Support for Moonriver and Moonbeam Mainnets, Migrating Tokens to Base

Binance, the world’s largest cryptocurrency exchange by trading volume, has announced it will end support for the Moonriver (MOVR) and Moonbeam (GLMR) legacy mainnets. The exchange will migrate both tokens to the Base network, a layer-2 blockchain developed by Coinbase.

Migration Timeline and Key Dates

According to the official announcement, deposits and withdrawals of MOVR and GLMR via the Moonriver and Moonbeam mainnets will be suspended starting at 11:00 a.m. UTC on July 21. After the migration is completed, deposits and withdrawals through these legacy mainnets will no longer be supported. Binance has advised users to complete any pending transactions before the deadline to avoid potential loss of funds.

Why This Matters

The decision to migrate MOVR and GLMR to Base represents a strategic shift in infrastructure for these Polkadot-parachain-based tokens. Moonriver and Moonbeam are both smart contract platforms built on the Kusama and Polkadot ecosystems, respectively. Base, by contrast, is an Ethereum layer-2 scaling solution that has rapidly gained traction since its launch, offering lower fees and faster transaction finality.

For holders of MOVR and GLMR, the migration means they will need to use Base network addresses for future deposits and withdrawals on Binance. Users who hold tokens on the Moonriver or Moonbeam mainnets may need to bridge their assets to Base through supported cross-chain bridges before depositing them on the exchange.

Implications for the Ecosystem

This move by Binance could signal a broader trend of centralized exchanges consolidating support around a smaller number of high-activity networks. By migrating to Base, Binance is aligning with a network that benefits from Coinbase’s user base and developer tooling. For the Moonbeam and Moonriver communities, the change may reduce direct liquidity on their native chains but could increase accessibility for traders who prefer the Base ecosystem.

Binance has not disclosed whether it will support any future token swaps or airdrops related to the migration. Users are encouraged to monitor Binance’s official announcements for any additional instructions.

Conclusion

Binance’s decision to end support for the Moonriver and Moonbeam legacy mainnets and migrate MOVR and GLMR to Base is a significant infrastructure update for token holders. With the suspension deadline set for July 21, users should act promptly to ensure their assets are accessible after the migration. The move highlights the ongoing consolidation of exchange support around layer-2 networks like Base.

FAQs

Q1: What happens to my MOVR and GLMR tokens if I don’t withdraw before July 21?
After the suspension, deposits and withdrawals via the Moonriver and Moonbeam mainnets will no longer be supported. Your tokens will remain on the blockchain, but you will not be able to deposit or withdraw them through Binance using those networks. You may need to use a cross-chain bridge to move them to Base before depositing.

Q2: Will Binance support the migration automatically?
Binance has not confirmed automatic conversion. Users are advised to check the official announcement for detailed instructions. It is likely that users will need to manually bridge their tokens to the Base network.

Q3: Is the Base network safe for storing MOVR and GLMR?
Base is a layer-2 Ethereum scaling solution developed by Coinbase and secured by Ethereum’s consensus mechanism. It has undergone multiple security audits. However, as with any blockchain network, users should exercise caution and only use official bridges and wallets.
