Coinbase has significantly expanded its Solana integration by enabling direct deposits and withdrawals of SOL via the Base network. This major update, launched on December 4, 2025, establishes a direct bridge between the Solana and Ethereum ecosystems, allowing users to transfer SOL directly within Coinbase's system without relying on external third-party bridges.
The integration treats SOL on Base as an ERC-20 compatible token, unlocking its use within Ethereum-based decentralized applications (dApps) and DeFi protocols. This move is designed to simplify cross-chain asset movement, reduce settlement times, and minimize interoperability risks by keeping transfers internal to Coinbase's infrastructure. The bridge is secured using Chainlink's Cross-Chain Interoperability Protocol (CCIP).
Operationally, users can now send SOL directly from Coinbase to wallets on the Base network using a standard withdrawal flow. The process involves selecting SOL, choosing the Base network, entering a destination address, and confirming the transaction. Deposits follow a similar reverse process. This integration is aimed at enhancing liquidity for both the Solana and Base ecosystems, potentially increasing the utility of SOL and SPL tokens and boosting Total Value Locked (TVL).
Coinbase CEO Brian Armstrong stated the company aims to be the "'everything exchange' for onchain assets," noting that this integration makes "millions of assets on Base and Solana now available in the main Coinbase app." Johann Eid, Chief Business Officer at Chainlink Labs, highlighted the security aspect, saying CCIP enables "developers to build secure cross-chain applications and move the industry toward a reliable interoperability standard."
It is important to note that regional restrictions apply. Access to SOL on Base via Coinbase is currently limited in New York, Canada, the United Kingdom, Japan, and several countries in Europe and the Asia-Pacific region, subject to local regulatory frameworks.
