Coinbase, the largest US-based cryptocurrency exchange, has announced the expansion of its spot trading platform with the addition of three new altcoins: Kamino (KMNO), Dolomite (DOLO), and Solayer (LAYER). The exchange confirmed via its official X account that trading for these tokens would begin on or after 9:00 AM Pacific Time, contingent on liquidity conditions and regulatory approvals in supported regions.
KMNO and DOLO will be available on Coinbase.com, the Coinbase app, and Coinbase Advanced, with institutional access via Coinbase Exchange. The exchange provided specific contract addresses for each asset: LAYER and KMNO on the Solana network (SPL tokens), and DOLO on the Ethereum network (ERC-20). Coinbase emphasized that tokens must only be sent via these correct networks to avoid permanent loss of funds.
Following the announcement, all three tokens experienced immediate price increases: KMNO rose 7.02% from $0.057 to $0.061, DOLO climbed 8.33% from $0.18 to $0.195, and LAYER advanced 9.43% from $0.53 to $0.58. However, volatility ensued shortly after. At press time, KMNO traded at $0.059 (up 0.36%), LAYER maintained a nearly 3% increase at $0.55, while DOLO shed all gains, dropping to $0.17 (down ~3%).
Coinbase also addressed its listing process transparency in a detailed blog post, explaining that applications are free and judged on equal standards, with timelines varying from hours to months based on project complexity. The exchange noted that tokens on supported networks (Ethereum, Base, Solana, Arbitrum, Optimism, Polygon, and Avalanche) can be listed faster, typically under 30 days from review to listing. Assets undergo phased launches—deposits, auctions, limit-only trading—before full trading to ensure healthy liquidity and market integrity.
