Papertrade prices trades at mid-market using the Hyperliquid best bid and offer oracle with zero execution slippage

Papertrade relies exclusively on Hyperliquid's best bid and offer (BBO) mid-price as its sole oracle source to price all open trading positions

Because Papertrade offers up to 1000x leverage, small price movements in its single Hyperliquid BBO mid-price oracle source can trigger large gains or liquidations across the platform

Single-source BBO oracle pricing creates unacceptable risk for synthetic exchanges

Papertrade prices every perpetual trade at the midpoint of Hyperliquid's current best bid and offer on HyperEVM

Pragma's September 18, 2026, assessment warned lenders that an available oracle token price does not guarantee that collateral can be successfully sold to cover a loan.

Oracle provider Pragma released a liquidity report on September 18, 2026, classifying 6 of 22 mainnet market and rate feeds as critical risk.

Trueo plans to prioritize attracting liquidity to major market categories and launching its next-generation oracle system immediately following Trueo's migration to Ethereum mainnet
