Coinbase announced that it has completed preparations to launch spot trading support for Superfluid (SUP) and Toncoin (TON). The US-based exchange announced that both altcoins will be listed on the platform by November 18, 2025. The listings will be phased in; order books will only become active when the required liquidity threshold is met.
The rapid increase in visibility for SUP, in particular, was notable following the announcement. The project has been frequently discussed in the developer community in recent months due to its structure offering "real-time token flow" through smart contracts. The Superfluid protocol provides an alternative architecture to Web3 payment models, enabling continuous asset transfers on a per-second basis without block times or manual payment triggers. Coinbase's SUP listing directly addresses this growing interest.
Volatility warning issued
According to information shared by Coinbase Markets, the SUP/USD trading pair can become active at any time during the day, due to internal liquidity checks and market makers ensuring order depth. The exchange stated that not sharing a fixed opening time was chosen to protect the market from manipulative sudden movements and to initiate price discovery more effectively.
Users were also warned of potential volatility in the early hours. Coinbase reminded users to use limit orders, open positions gradually, and avoid aggressive market buying, emphasizing that the order book naturally stabilizes over time in new listings.
Toncoin, which emerged from the Telegram ecosystem, is following a different listing process due to its larger user base. The opening for the TON-USD pair is expected to occur in the evening hours of November 18, 2025. The Coinbase listing is known to have been long-awaited by the market, as the TON ecosystem has continued to grow in terms of both user activity and on-chain speed over the past two years.
TON stands out with its fast block times, low transaction costs, and mobile-focused usage advantages, while its DeFi and mini-app ecosystems continued to expand throughout 2025. The listing is expected to provide TON with greater visibility in the US market. Coinbase stated that both altcoins may not be available in all regions. Due to regulatory restrictions, trading in SUP and TON will be restricted in some countries. Users are urged to check availability in their respective regions before opening a trade.
A critical technical caveat has also been issued for SUP: The asset will only be supported on the Base network. Coinbase issued a stern warning that transfers to networks other than the specified smart contract address could result in permanent losses.
