Propr

Propr is a crypto proprietary trading firm built onchain on Hyperliquid. Traders pay a one-time, non-refundable evaluation fee to take a challenge account; if they reach the profit target without breaching two equity limits (a maximum daily loss and a maximum drawdown), they receive a funded account with no profit target and keep 80% of the rewards they generate. Funded traders can hold up to $300,000 in allocated capital at once across multiple accounts, and the firm advertises 160+ perpetual markets on Hyperliquid spanning crypto, equities, indices and commodities, with prediction markets on Polymarket listed as a forthcoming account type. Payouts are on demand, settle in USDC onchain within minutes, and are displayed on a public transparency dashboard.

The rulebook governs Classic 1-Step, Turbo 1-Step, Pro 1-Step and Classic 2-Step evaluations across account sizes of $5,000 to $200,000. Fees range from $25 (Turbo $5,000) to $1,998 (Classic $200,000). One-Step accounts carry a 3% daily loss limit measured against start-of-day balance and a static maximum drawdown of 3% (Turbo), 5% (Pro) or 6% (Classic); Classic 2-Step accounts use a 5% daily loss limit and an 8% trailing drawdown that resets after a payout and never rises above the starting balance. Profit targets are 9% (Turbo), 10% (Classic), 12% (Pro) and 5% then 10% for the two-step path. There are no time limits, minimum trading days or consistency rules, and a breach ends the account without the trader owing losses. Leverage is capped at up to 10x on equity and index perps, 8x on commodities and 5x on major crypto. A one-time KYC check is required before rewards are enabled.

Propr also positions itself for algorithmic and agent-based trading, offering a REST API with Python and JavaScript SDKs; the site cites over 300 API users or agents. It frames transparency as a core mechanic: trades are labelled A-book or B-book with the split published in real time, hedging wallets are public, rule changes are logged in a dated public changelog, and active funded accounts remain governed by the rules in force at activation.

Founding story

Propr was founded by Louis Regis, who serves as CEO and publicly documents the build. The founding profile cited by the company includes prior roles as a risk quant at Credit Suisse and crypto lead at Rothschild & Co, a top-10 finish in ByBit's WSOT trading competition, and early power use of Hyperliquid.

Business model

Traders pay a one-time, non-refundable evaluation (challenge) fee to attempt a funded-account qualification; Propr retains the fee regardless of outcome and, on funded accounts, keeps 20% of trader gains while the trader keeps 80%. The firm also decides whether to mirror a trader's signals onchain (A-book) or take the other side internally (B-book), and hedges its own risk onchain.

Evaluation fees ranging from $25 to $1,998 depending on account size and challenge type, plus a 20% share of funded-trader rewards.

Traction

The website cites 160+ tradable perpetual markets, over 300 API users or agents, funded capital allocations of up to $300,000 per trader, and a 4.5 rating based on 54 reviews. Live counters for active traders, 30-day payouts, median payout time and countries served are published on the site's transparency dashboard. The company has been featured by CryptoSlate.
