OKX is the third-largest cryptocurrency exchange by trading volume, founded in 2017 by Star Xu and processing roughly $40 billion in daily derivatives turnover across one of the deepest perpetuals order books in the market.

Perpetual swaps run up to 100x leverage in USDT, USDC, and coin-margined variants, backed by a unified account that margins spot, futures, and options from one collateral pool. OKX was also the first global exchange to list perpetuals priced on licensed ICE Brent and WTI oil benchmarks, extending its engine beyond crypto.

Its regulatory footprint is among the broadest in the industry. A MiCA license from Malta's MFSA passports across the EEA alongside a MiFID II derivatives venue, approvals include VARA, MAS, and AUSTRAC, and a compliant US entity relaunched from San Jose after settling with the Department of Justice.

Custody claims are verifiable rather than asserted. More than 40 consecutive monthly Proof of Reserves reports use zk-STARK cryptography to show over $20 billion in primary assets covered above a 1:1 ratio, and the main exchange has no major disclosed hack in its history.

Kraken is the most heavily regulated major perpetuals venue and one of the oldest exchanges in crypto, founded in 2011 and now operating under parent Payward at a $20 billion valuation following an $800 million raise and a confidential IPO filing.

Its derivatives platform runs perpetuals at up to 50x leverage with a structure rivals don't match, settling funding hourly rather than every 8 hours and accepting BTC, ETH, and other assets directly as multi-collateral margin.

Regulation is the moat. Kraken holds MiCA authorization through the Central Bank of Ireland, a MiFID derivatives license, and the only full CFTC stack held by a crypto-native firm, making it one of the few venues offering regulated perpetual futures to US traders.

Security rests on a record no major rival shares. The exchange has never suffered a major breach in its history, backs custody with audited Proof of Reserves and a Wyoming-chartered bank, and holds ISO 27001 and SOC 2 certifications.
