💨 What’s happening: After a steady first half, smart contract activity on Sei increased sharply in the latter half of 2025, as new game launches brought in new users and spurred usage of existing contracts. 

💨 Why it matters: Smart contract activity provides much more color and insight into how a network is being used compared to raw transaction numbers. An influx of new contracts is often an indicator of promotional campaigns, application launches and new features drawing new users to the ecosystem, while activity on existing contracts is a measure of user retention and engagement.

Contract activity on Sei remained relatively stable for most of the year: through September, the 30-day moving average ranged between 500-800 contracts, and returning contracts held between 400-700, indicating consistent but moderate levels of ongoing contract engagement.

Activity levels shifted later in the year, primarily due to the launch of blockchain games like Match Fighters and Solo Survivor. November saw a significant increase in usage, with the 30-day moving average increasing to 1,000-1,500 contracts. Returning contracts also rose, maintaining levels between 1,000-1,200 through the end of the year. By December 2025, returning contracts had exceeded the moving average.

Together, these applications facilitated an average of 3 million to 4 million transactions. Sustained activity on the World of Dypians game also kept numbers high, between 600,000 and 700,000 transactions, though that was offset by declines in other applications, which fell from around 5 million to 2 million transactions.

The 30-day moving average of active contracts, which shows sustained trends in contract usage, rose to 1,187 by the end of the year from 570 in early January. Meanwhile, daily returning contracts increased to 1,361 from 445, while new contract deployments jumped to 42 from 5.

Even though Sei’s TVL had declined to $191 million by December 31 from $300 million just two months earlier, the percentage of Sei TVL in popular protocols like Yei Finance, Takara Lend, Sailor and DragonSwap, did not change. This shows that capital remained relatively sticky within some of the network’s most popular protocols, further spurring sustained reuse of existing smart contracts.

💨 The bigger picture: For much of 2025, contract activity on Sei remained within a certain range, indicating steady levels. But the sharp increase in November points to how ecosystems like Sei grow: Early experimentation paves the way for users to return once applications find product-market fit in a network’s ecosystem. 

While some applications did run incentive programs this year on Sei, promotional campaigns usually only inflate numbers temporarily, and the steady momentum with smart contracts on the network throughout the year proves otherwise. 

Taken together, these trends suggest that Sei experienced both increased application persistence and higher overall contract engagement in the second half of 2025.
