Crypto trading terminal Nexa, formerly known as InsiDeX, is shutting down just a year after its acquisition by decentralized exchange Bluefin, citing what it calls “extremely low” trading volumes on the Sui blockchain.
In a Feb. 10 post on X, the team said “only 2-3 coins [are] seeing some decent activity” on Sui, leaving traders with few real opportunities, and added that it was built for fast trades and active markets, conditions that never appeared.
“There’s a real sense of sadness in shutting down Nexa because we succeeded in building a product that was actually the most used trading suite on Sui at one time. Unfortunately, the market it was built for never truly materialized,” the team wrote.
The shutdown follows months of Nexa pushing points-based rewards and other engagement schemes, but that campaign went quiet before the closure.
The move highlights broader weakness across Sui’s DeFi ecosystem. As of Feb. 12, 2026, DefiLlama data shows total value locked (TVL) on Sui at about $561 million, down roughly 78% from a peak of $2.6 billion in October 2025.

DEX volumes have also dropped, falling around 70% from $22.3 billion in October to about $6.8 billion in January. Sui’s native token SUI has also dropped around 50% over the past month to $0.93, per data from CoinGecko.
Moreover, the start of 2026 was rocky for the Sui blockchain as it suffered a six-hour outage that stopped block production. The team later explained that the problem was a bug in the network’s consensus system, which caused validators to disagree on data and temporarily froze transactions.
But Sui isn’t the only network facing challenges amid falling liquidity, as a similar story is unfolding on rival chains like Aptos. As The Defiant reported earlier this month, Merkle Trade — the largest perpetual DEX on Aptos by volume — said it would wind down operations despite processing nearly $30 billion in cumulative trades, as TVL across the network continued to fall too.
