Sui’s 2025 numbers tell a story of scale and stress. The network executed more than 1.16 billion programmable transaction blocks over the year, while securing 113 terabytes of data on‑chain. Institutions and independent builders both leaned in, pushing adoption across DeFi, gaming, and infrastructure.
At the center of this activity sits DeepBook, now widely seen as the liquidity backbone for on‑chain trading. By aggregating order flow and anchoring swaps, DeepBook has become the default venue for projects seeking reliable execution. Its rise underscores how Sui is positioning itself not just as a high‑throughput chain, but as a marketplace with depth.
Activity Metrics Show Mixed Picture
Despite headline growth, weekly activity dipped into year‑end. Transactions fell to 28.05 million, down 20.1% from prior levels. Weekly active addresses dropped to 1.32 million, a 25.19% decline. Total value locked (TVL), tracked by DefiLlama, closed at $933.27 million, slipping 3.68%.
The slowdown reflects broader market conditions. Crypto volumes cooled in Q4 as traders rotated into majors like Bitcoin and Ethereum. For Sui, the dip highlights the challenge of sustaining retail engagement while institutional adoption ramps up.
Still, the long‑term trajectory remains intact. Billions of executed blocks and terabytes of secured data show that the chain is handling real workloads. With DeepBook cementing itself as a liquidity hub, Sui enters 2026 with infrastructure that can support the next wave of growth.
