0x ("zero x") is an open, permissionless protocol allowing for ERC-20 tokens to be traded on the Ethereum blockchain.[1]


According to its white paper, the 0x Project intends for the protocol to serve as a building block to be combined with other protocols to drive decentralized applications.[2] 0x seeks to increase transaction speeds and reduce user costs by allowing certain orders to be relayed off the blockchain while settling final transactions on the blockchain.[3]

0x (ZRX) is also the name of a tradable token that was issued by the 0x Project (as ZeroEx,Inc.) in an ICO in August 2017 having earlier raised $775,000 in a SAFT (Simple Agreement for Future Tokens).[4] The SAFT was registered with the SEC in a Form D filing.[5] The 0x Project reportedly raised its seed amounts from various venture firms, including Polychain Capital, Blockchain Capital, Pantera Capital, Jen Advisors and FBG Capital.[6]

In mid November 2020, ZRX had a market capitalization of more than $360 million, making it the 47th largest cryptocurrency in U.S. dollar terms according to online data provider CryptoCompare.[7]


Coinbase, the U.S.-based wallet provider and trading platform, began supporting ZRX in its wallets in early October 2018. The U.S. dollar price of ZRX shot up by 16% on the news.[8] The Coinbase platform announced on October 16, 2018 that its customers would be able to buy and sell the coin from all of their accounts at Coinbase.[9]
