Coinbase made two opposing decisions concerning three altcoins on the same day. The exchange added Basecat and DebtReliefBot, both built on Base, to its spot market while announcing plans to end trading support for IoTeX.
The BASECAT-USD and DRB-USD pairs entered a phased launch process. IOTX trading is scheduled to stop at around 9:00 p.m. Turkey time on September 23, 2026.
Coinbase launches BASECAT and DRB trading
According to Coinbase Markets' announcement, spot trading for Basecat (BASECAT) and DebtReliefBot (DRB) went live on August 24. The exchange created US dollar trading pairs for both assets.
Coinbase offers the BASECAT-USD and DRB-USD pairs in supported regions. Users can access the markets through Coinbase Advanced.
Institutional clients can trade the assets through Coinbase Exchange.
The exchange initially placed the pairs in auction mode. During this stage, investors can submit limit orders and view the indicative opening price.
Coinbase uses this process to facilitate price discovery and establish sufficient liquidity in new markets.
Both tokens entered Coinbase’s listing roadmap on August 21. Inclusion in the roadmap alone does not mean that trading support has started.
The exchange publishes a separate trading announcement once market-maker support and the required technical infrastructure are ready.
Both tokens run on Base
Coinbase supports only the Base network versions of BASECAT and DRB. The exchange identified BASECAT’s contract address as 0xb2000000000000000000004c27f6523082f41d01.
The contract address provided for DRB is 0x3ec2156D4c0A9CBdAB4a016633b7BcF6a8d68Ea2.
Basecat is a memecoin featuring a cartoon cat wearing a blue construction hardhat. Coinbase data shows that the token has a circulating supply of around 1 billion.
DebtReliefBot combines memecoin and artificial intelligence themes. The name was proposed by xAI chatbot Grok in March 2025.
According to the project’s community portal, a crypto bot called Bankr later created DRB on Base.
Base’s official documentation describes the network as an Ethereum Layer 2 solution incubated within Coinbase. The network aims to offer faster and cheaper transactions while maintaining Ethereum compatibility.
BASECAT and DRB face selling pressure
Trading volumes for both assets increased during the listing process. Selling pressure emerged after the initial price movements.
Market data showed BASECAT trading at $0.0292 as of 12:08 p.m. Turkey time on August 25. The token fell 18.5% over 24 hours, while its trading volume approached $19 million.
DRB traded at around $0.0001532 at the same time. Its daily loss reached 19.5%, while its weekly gain remained at 469%.
This performance indicated stronger profit-taking after the rapid rally that preceded the listing.
When will Coinbase suspend IOTX trading?
Coinbase took the opposite direction with IoTeX. According to the exchange’s announcement, IOTX trading support will end at around 2:00 p.m. Eastern Time on September 23.
This corresponds to 9:00 p.m. in Turkey.
The decision covers Simple and Advanced Trade on Coinbase.com. Coinbase Exchange and Coinbase Prime clients will also be unable to trade IOTX after the stated time.
The exchange has already moved its IOTX order books to limit-only mode. Users can submit limit orders or cancel existing orders during this period.
Trades can continue to match when the required conditions are met.
Coinbase said customers would retain access to their balances. Investors will still be able to withdraw IOTX from the platform after trading support ends.
The exchange said it reached the decision after a regular asset review. It did not disclose which listing standard IOTX had failed to meet.
It therefore remains unclear whether the decision relates to liquidity, technical infrastructure or compliance requirements.
The version of IOTX traded on Coinbase operates on Ethereum. Users planning to withdraw their assets need to verify the destination wallet and network.
IoTeX’s deposit and withdrawal guidance states that Coinbase accepts only the ERC-20 version. Sending native IOTX directly to an Ethereum deposit address on Coinbase could result in a loss of funds.
The delisting announcement did not initially trigger a sharp decline in the global IOTX price. CoinGecko data showed IOTX trading at $0.00282 as of 12:08 p.m. Turkey time, up 0.8% over the previous 24 hours.
