Cryptocurrency exchange Coinbase has listed its first Ethereum-based token, 0x (ZRX), on its professional trading platform Coinbase Pro.

The exchange is now accepting deposits for ZRX and, once sufficient liquidity is established, trading will begin on the ZRX/USD, ZRX/EUR and ZRX/BTC order books.

Coinbase says there will be four stages to the launch, which it will follow independently for each new order book.

In the first “transfer-only” stage, which started at 10am PT on 11th October, customers will be able to transfer ZRX into their Coinbase Pro account. Order books will be in transfer-only mode for at least 12 hours.

In the second “post-only” stage, customers can post limit orders but there will be no matches (completed orders). Order books will be in post-only mode for a minimum of one minute.

In the third “limit-only” stage, limit orders will start matching but customers will be unable to submit market orders. Order books will be in limit-only mode for a minimum of 10 minutes.

In the final stage, full trading services will be available, including limit, market and stop orders.

Coinbase says ZRX trading will be offered in most jurisdictions, but will not initially be available for residents of New York state. In addition, the token is not yet available through the coinbase.com website or its iOS and Android apps.

The listing comes after Coinbase announced in March that it intended to add support for ERC-20 tokens on its exchange.
