Base, the Coinbase-backed EVM chain pitched as Ethereum’s own layer 2, has just received high praise from none other than Vitalik Buterin himself.
In a rare endorsement on social media, Vitalik lauded Base as the optimal solution for scaling Ethereum, offering a speedier user experience through centralized sequencing while maintaining a strong connection to Ethereum’s security layer, ensuring the safety of funds.
Vitalik emphasized that Base does not hold custody of funds, with withdrawals secured by the Ethereum mainnet code. The L2Beat stage 1 tag provides genuine protection against rug pulls, rather than mere marketing claims. He also dispelled the notion that layer 2 solutions are merely “servers,” pointing to instances where censorship was thwarted and funds remained secure even when operators were offline.
Base’s security council structure includes external members to prevent any single entity from exerting unilateral control.
Coinbase CEO Armstrong’s Response
Brian Armstrong expressed his support for Base with a brief comment, “Great thread to read through on Base,” indicating Coinbase’s alignment with Vitalik’s endorsement.

Jesse Pollak from the Base team detailed how sequencers operate, bundling and ordering transactions before the main layer settles them. Users can bypass Base and interact directly with Ethereum at any time. Base currently operates with stage-1 decentralization, featuring permissionless block proposals, with stage 2 development underway.
The Legitimacy of Base
The consensus is clear: Base is not a custodial sidechain or disguised exchange. It stands as Ethereum infrastructure designed for scalability without compromising trust. With endorsements from Vitalik and amplification from Armstrong, any doubts surrounding Base’s legitimacy seem to have been put to rest.
