## What is the Onchain of Fundamental Data Sources?

Primary inputs for cryptocurrency derivatives originate directly from distributed ledgers, capturing raw transaction volumes, wallet activity, and liquidity distribution across decentralized protocols. These datasets provide transparent evidence of network health and capital flow, which serve as the foundation for quantitative risk modeling. Analysts leverage this information to verify asset provenance and assess the stability of collateral underlying various synthetic instruments.

## What is the Offchain of Fundamental Data Sources?

Traditional exchange interfaces deliver essential order book dynamics, including high-frequency bid-ask spreads, trade execution timestamps, and aggregate open interest figures. This data informs the calculation of perpetual funding rates and informs basis trading strategies essential for market neutral exposure. Accessing centralized venue data allows traders to calibrate volatility models against actual liquidity constraints and latency performance.

## What is the Oracle of Fundamental Data Sources?

Independent verification layers bridge the gap between external financial assets and blockchain-based derivative contracts by providing real-time, tamper-resistant price feeds. These systems synthesize multiple price discovery points to mitigate the impact of localized manipulation or liquidity outages on decentralized platforms. Trustworthy data feeds ensure that margin calls, liquidation triggers, and settlement calculations remain accurate and resilient against adversarial market conditions.
