Coinbase's Base and Solana Networks Now Interconnected via Chainlink-Powered Bridge

Coinbase's Ethereum layer-2 network Base has officially launched a bridge to the Solana blockchain, enabling seamless asset transfers between the two major ecosystems. The integration, powered by Chainlink's Cross-Chain Interoperability Protocol (CCIP), went live on December 4, 2025, and is already operational in popular Base applications like the token launchpad Zora and the network's largest decentralized exchange, Aerodrome.

The bridge allows users to move assets "at the speed of the internet" between Base and Solana. It enables builders on Base to support Solana's SPL tokens in their applications, allows users to trade Solana assets on Base, and lets communities tap into liquidity across both networks. Conversely, it also enables the export of Base assets onto Solana. The Base team emphasized that this is a step toward its goal of serving as a hub for an "everything economy: every asset, across every network, at any time."

The security of the bridge is a joint effort. It uses a "bespoke cross-chain oracle" where both Coinbase and Chainlink node operators independently verify all messages, ensuring token transfers are safe and reliable. The bridge's open-source nature means other applications can implement it, allowing users to trade assets regardless of which network they are using.

This integration follows hints from Base creator Jesse Pollak, who suggested a Solana integration was underway as early as August 2025 and reaffirmed the commitment during Base's September Basecamp event. Base, launched in August 2023 and built on the Optimism tech stack, has grown rapidly. It is now the fifth-largest blockchain by bridged Total Value Locked (TVL), with a TVL of $14.89 billion as of early December, having seen a nearly 5% boost in the prior week. Solana's TVL stands at $29.4 billion.
