Deribit

Deribit is a centralized cryptocurrency derivatives exchange specializing in Bitcoin and Ether options, perpetual futures and crypto-collateralized margin. Customer positions, collateral and settlement remain within exchange-controlled accounts, while the platform's portfolio-margin and block-trading systems serve active and institutional derivatives users. This tag should cover contract specifications, options expiries, margin rules, liquidation procedures, fee schedules, custody, outages, security incidents and jurisdictional access. Options analytics and implied-volatility data from independent providers require separate tags, as do BTC and ETH market stories that do not directly affect trading or settlement on Deribit.
