Hashmarket operates globally through separate legal entities. Hashmarket is a web interface to self-executing smart contracts on the public Ethereum blockchain. It is not an exchange, broker, counterparty, or custodian ("the house") and does not take the other side of user trades. The Interfaces are intended only for users who are at least twenty-one (21) years of age (21+). We do not market to or solicit U.S. persons or users in other restricted jurisdictions (including Crimea, the Russian Federation, Iran, Somalia, Israel, and other regions listed in our Terms). Nothing on this site is an offer to sell or solicitation to buy financial instruments where prohibited. Contact: support@hashmarket.app.
