Binance users can now deposit any ERC-20 tokens from the Ethereum network using Arbitrum quickly and at a reasonable cost.
On Friday, Binance announced the integration of the Arbitrum One core network and opened Ether (ETH) deposits on the Arbitrum One layer two.
Arbitrum
 is a third-generation layer-two optimistic rollup protocol that runs on
 an off-chain Ethereum contract and has lower costs and faster 
transactions than on the Ethereum mainnet.
The announcement notes 
that Binance users can now deposit any ERC-20 token from the Ethereum 
network with Arbitrum at a reduced transaction cost. In addition, 
Binance also stated that it will enable ETH withdrawals on the Arbitrum 
One Network layer two in the near future, making it one of the first 
centralized exchanges with layer-two support.

Ethereum,
 arguably the most prominent blockchain network in the world, has been 
hampered by network congestion and exorbitant fees, stymieing its 
exponential growth. Arbitrum One offers a solution to this problem by 
utilizing a multilayered Ethereum consensus protocol that allows for 
unlimited scalability and near-instantaneous transaction times at a 
fraction of the cost.
Binance’s integration of layer-two ETH 
deposits is a significant step forward, coming at a time when 
decentralized exchanges and cross-chain atomic swaps are gaining 
popularity in the market. Binance is one of the world’s largest 
cryptocurrency exchanges by volume, and the Arbitium integration is good
 news for Ethereum adoption.

The
 launch of the Arbitrum One Network layer two did not include an 
announcement for ETH withdrawals, but it did promise that more 
information would be provided when this functionality is available to 
traders. However, it has been reported that Binance is preparing to let 
users withdraw their funds directly to Arbitrum.
According to a tweet from Lark Davis, a crypto investor from New 
Zealand, Binance is working on allowing direct ETH withdrawals to 
Arbitrum. According to Lark, the integration will be “MASSIVE for 
Ethereum adoption.” A screenshot showing reduced transaction costs and 
time is included with the message.
The integration of layer-two functionality is a major stride forward in the right direction, as Ethereum strives toward scalability and Ethereum 2.0.
 It’s worth noting that the launch of Ethereum 2.0 won’t stop layer-two 
platforms from working to solve for scalability. Instead, technologies 
like rollups or side chains will continue to aid Ethereum 2.0 scale 
beyond its current capacity once sharding is completely implemented.
