Base's cross-chain expansion accelerates. Base has become the dominant destination for bridged assets, holding 37.92% of Ethereum's bridged Total Value Locked (TVL) as of May 2025 — the largest share of any chain, ahead of Arbitrum (25.51%) and Polygon (19.90%) 1. This consolidation reflects Base's growing role as a primary hub for assets moving onto Ethereum Layer 2 networks.
New Base–Solana bridge goes live. A custom-engineered bridge connecting Base and Solana launched to enable direct asset and message transfers, using a "lock and mint" mechanism where assets are locked on one chain and a representation is minted on the other 2. The bridge is secured by Chainlink's Cross-Chain Interoperability Protocol (CCIP) and independently verified by Coinbase node operators, allowing Base developers to natively support Solana assets like SOL and SPL tokens 3. This matters because it positions Base as a hub for cross-network assets and reduces reliance on third-party bridging options.
Lido rethinks wstETH bridging. At SmartCon 2025, Lido discussed the limitations of wrapped staked ETH (wstETH) — a tokenized, transferable version of staked ETH — noting that its canonical bridging to 15 chains is slow and lacks a scalable way to move between chains without returning to Ethereum mainnet . The proposed future uses a "burn and mint" model via Chainlink's CCIP to enable faster, cheaper, and more secure cross-chain transfers . This is directly relevant to bridged wstETH on Base, as it signals a potential shift in how the asset is moved and secured across networks.
