Confused about transferring your cryptocurrencies to Base? We'll guide you through the most popular bridging options to move ETH to Coinbase's newly launched Layer 2 platform.
On August 9, the Base mainnet officially opened to the public, allowing non-technical users to explore the platform. Since its launch, this Ethereum Layer 2 has experienced significant ecosystem growth, with over 50 protocols now operational. The largest of these, BaseSwap, boasts a TVL exceeding $50 million.
In total, Base's TVL surpasses $167 million, making it one of the fastest-growing Ethereum L2 solutions and currently the third-largest optimistic rollup-based L2 (behind Arbitrum and Optimism).
To begin using Base, you'll need to load ETH onto the platform for gas fees. Once your wallet is funded, you can start interacting with the Base ecosystem.

- Have ETH in your Ethereum wallet (purchasable via exchanges like Coinbase, Binance, or CEX.io)
