SUI, the native token of the Sui blockchain, fell Tuesday after breaching critical support levels and triggering a wave of technical selling. The token dropped 9.2% to as low as $2.02 as trading volume spiked and recovery attempts repeatedly failed.

The sell-off followed Monday's news of a $116 million exploit involving decentralized finance (DeFi) protocol Balancer, which has rattled sentiment across the industry.

As security concerns mounted, investors appeared to unwind exposure to riskier layer-1 tokens, with SUI showing signs of institutional liquidation, according to CoinDesk Research's technical analysis model. Nearly 42.6 million tokens changed hands during the breakdown, 68% more than the daily average, according to on-chain data.

The $2.08 level — once a support zone — flipped into resistance during the rout, with multiple failed bounces reinforcing the bearish trend. During U.S. morning hours, SUI hovered around $2.02 in low-volume trading, suggesting traders were positioning ahead of the next major move.

Chart watchers noted classic capitulation behavior: a single-hour collapse, followed by lower highs and tight consolidation. If the token breaks below $2.014, technical targets point toward $1.98 or even $1.95. To regain momentum, bulls would need to reclaim $2.07 with conviction.

The CoinDesk 5 Index of the biggest cryptocurrencies dropped 1.15% on the day with all constituents lower.
