Coinbase has updated its listing roadmap to include Checkmate (CHECK) and Sign (SIGN), while also confirming a listing for Perle (PRL). The exchange separately said spot trading for Impossible Cloud Network (ICNT) is set to begin under the ICNT-USD pair at or after 9:00 AM Pacific Time on March 25, 2026, subject to liquidity requirements.
CHECK and SIGN join the roadmap, not live yet
The roadmap addition does not mean immediate trading. Coinbase said CHECK and SIGN will only go live after market-making support, liquidity readiness, and technical infrastructure are in place. The exchange plans to publish a separate notice once those conditions are met and an actual trading schedule is ready.
That approach matches the onboarding process Coinbase has used since 2023. Assets are placed on the public roadmap first, then moved toward launch only after operational and market conditions meet the exchange’s standards.
Two projects, two distinct blockchain themes
According to the source material, Checkmate (CHECK) is tied to Anichess, a blockchain chess gaming platform expected to be released in late 2025. The token is intended for in-game economies, governance, and AI-based gameplay elements, placing it in the GameFi segment. Sign (SIGN), tied to Sign Protocol, is described as a sovereign infrastructure platform focused on digital identity systems, national-scale blockchain applications, and possible CBDC-related use cases.
The two additions point to different parts of the market. CHECK is linked to gaming utility, while SIGN is positioned around digital identity and broader blockchain infrastructure.
Perle confirmation adds to Solana exposure
Coinbase also confirmed the listing of Perle (PRL). The report describes PRL as a DeFi-oriented token associated with the Perle Labs airdrop and built within the Solana ecosystem. Its addition gives Coinbase more exposure to SPL-based assets.
The source notes that confirmed listings such as PRL have often attracted strong early trading interest, especially when connected to newer DeFi narratives. No exact PRL trading time was provided in the material.
ICNT launch follows the usual liquidity gate
For Impossible Cloud Network, Coinbase said spot trading will start on March 25, 2026 under the ICNT-USD pair. Even with the listing in place, the exchange made clear that trading depends on sufficient liquidity. If market depth is not ready, the launch would wait until those conditions are satisfied.
This is a standard Coinbase setup. A listing decision and a live market are not treated as the same step, and the exchange continues to tie launch timing to trading readiness.
Roadmap additions are watched as early market signals
The report says Coinbase roadmap additions have historically acted as price catalysts, particularly for lower-cap tokens. It cites past market behavior suggesting that such announcements have at times produced 20% to 50% short-term gains. That reference is presented as a description of prior trading patterns, not as a forecast for the newly added tokens.
Community reaction in the article was broadly positive around Anichess and Sign Protocol, while some users also questioned Coinbase’s selective listing approach and pushed for other Base ecosystem tokens to be considered. Based on the update itself, the immediate takeaway is straightforward: CHECK and SIGN are now on the roadmap, PRL has been confirmed, and ICNT is one step closer to active spot trading.
