Key Highlights
Coinbase adds CHECK and SIGN to the roadmap, trading pending conditions
Perle PRL listing confirmed, expanding Solana ecosystem exposure
ICNT trading launches today, subject to liquidity and readiness
In a new announcement, Coinbase has announced Checkmate (CHECK) and Sign (SIGN) to its official listing roadmap, and has also confirmed the listing of Perle (PRL). The action underscores the ongoing momentum of the exchange towards transparency and systematic asset onboarding, a policy that it has pursued since 2023.
As announced, CHECK and SIGN cannot be traded right away. Market-making support, liquidity preparedness, and technical infrastructure alignment are critical factors that will determine their launch. The exchange explained that an announcement will be made to verify the actual trading schedules after these conditions are met.

The addition indicates that Coinbase is becoming more interested in new blockchain ecosystems:
Checkmate (CHECK) will be associated with Anichess, a chess game platform built on blockchain that will be released in late 2025. The token is used to operate in-game economies, governance, and AI-based gameplay elements, placing it in the emerging GameFi industry.
Sign Protocol is a sovereign infrastructure platform, with key participants such as Sign and Sequoia. It is devoted to digital identity systems and national-scale blockchain applications, as well as possible applications in CBDCs.
Both tokens are developed using contemporary blockchain technologies and address different issues, such as gaming utility and sovereign digital infrastructure, which makes them strategically diversified additions to the roadmap.
Coinbase exchange has also verified the addition of Perle (PRL), a DeFi-oriented token linked with Perle Labs airdrop, along with the additions to the roadmap. PRL is a Solana-based ecosystem that further exposes Coinbase to SPL tokens.
Historically, verified listings such as PRL frequently enjoy high initial trading, particularly when associated with new DeFi stories.

Similarly, Coinbase also stated that Impossible Cloud Network (ICNT) will start spot trading today on March 25, 2026, under the ICNT-USD pair. Trading to open at or after 9:00 AM Pacific Time, on liquidity conditions being met.
This is typical of Coinbase: even validated launches are subject to adequate market depth and stability to provide users with safer trading conditions.
Coinbase additions to the roadmap have served as price drivers in the past, especially among low-cap tokens. There is market evidence that 20% - 50% short-term returns could be generated by such announcements due to speculation and greater visibility.
Retail and institutional interest may be drawn to CHECK and PRL, as both have relatively young ecosystems, provided that the rest of the crypto market mood does not decline.
The crypto community has reacted positively, especially those who were behind Anichess and Sign Protocol. Coinbase has been challenged by some users on its selective listing approach, however, demanding that other Base ecosystem tokens be listed.
On the whole, the update strengthens the shifting role of Coinbase, no longer as a trading platform, but as an arbiter of new blockchain innovation.
