Coinbase has flipped the CTR-USD trading pair into limit-only mode, meaning both Coinbase Exchange and Coinbase Advanced will only accept limit orders for the Citrea token paired against the US dollar. Market orders are off the table for now.

What limit-only mode actually means for traders

In limit-only mode, traders can place new limit orders, cancel existing ones, and have their orders matched against others in the book. What they cannot do is fire off a market order that executes instantly at the best available price.

This isn’t Coinbase improvising. The exchange has a well-documented playbook for bringing new tokens onto the platform. Deposits get enabled first, then the pair enters a limit-only or auction phase, and eventually, if everything checks out, full trading opens up with market orders included.

Other tokens have gone through the same process. NEX-USD and WRON-USD both underwent similar limit-only periods during their respective listing sequences, following the same controlled rollout pattern.

What is Citrea, and why does it matter

Citrea, which trades under the ticker CTR, is a Bitcoin-native ZK-rollup project. In English: it’s a layer built on top of Bitcoin that uses zero-knowledge proofs, a type of cryptographic technique, to process transactions more efficiently while inheriting Bitcoin’s security.

The project has attracted notable backers. Citrea has received investment from Coinbase Ventures, along with other firms like Framework Ventures and Dragonfly.

Indicative pricing for CTR has been hovering around $0.03. At that price point, the token is firmly in micro-cap territory. Active trading data remains thin given the recency of the listing.

Deposit addresses for CTR are now live across Coinbase platforms, including the main exchange and the mobile app.
