The significance of Open Interest in decentralized finance (DeFi) cannot be understated, with Avalanche's dominance providing it a competitive advantage in terms of stability and long-term sustainability. Meanwhile, Avalanche [AVAX] was trading at $11.48, within a range of $8.77 to $12, showcasing its strong market position.

Balancing Momentum with Market Stability

Sei Network's recent increase in Perp Volume illustrates its growing attractiveness to active traders. However, Avalanche’s leading Open Interest still illustrates its superior market depth and liquidity resilience.

The next crucial step will depend on whether this user growth translates into a stronger presence in the derivatives market.
