# ProvePnL > A public registry of independently computed crypto trading records, for traders, investors and funds. Records come from public on-chain data (Hyperliquid, GMX on Arbitrum and Avalanche) and public copy-trading boards (Binance, OKX, Bybit, KuCoin, Gate, HTX, MEXC). A trader proves ownership by wallet signature or a read-only exchange key; the ✓ is shown only once their identity is also confirmed on a channel they control. - JSON leaderboard: https://provepnl.com/api/leaderboard?venue=hyperliquid|binance|okx|kucoin|bybit|gate|htx|mexc|gmx|gmx-avax - One record as JSON, with curves, proof level and score inputs: https://provepnl.com/api/record/
