SUI ran into a rough patch after a network-wide stall paused block production for several hours. BeInCrypto data shows the market cap dropped about 5% to $3.67B during the incident, while the SUI price slipped roughly 8% at the same time. Coin Bureau confirmed the situation, noting that the mainnet stopped processing transactions while developers worked on restoring normal operations.
Even though public RPC nodes were still running, the issue came from validator coordination breaking down. That matters because it interrupts final settlement on the chain, which is the core function of any Layer 1 network. When that part fails, confidence usually takes a hit fast, and that’s exactly what showed up in price action.
⚠️SUI DROPS -5% AS MAINNET SUFFERS NETWORK OUTAGE

The Sui team has confirmed a network-wide stall, with developers currently working on a solution.

At the same time, the broader crypto market wasn’t in great condition either. Bitcoin was down around 2.06%, so risk appetite was already weak before the outage hit. That made it easier for the SUI price to slide harder once the news spread.
What you'll learn 👉
SUI Price Falls Back Into a Key Support Battle
We had a look at the SUI chart shared by 2xnmore, and the breakdown below $1.00 stands out. That level wasn’t random; it acted as support during the entire 2024 base phase before SUI pushed toward the $4.00 region.
From the highs near $4.00 in early 2025, SUI is down about 77%, which places it deep inside a long correction phase. The structure has been pretty clear for months, with lower highs forming and every bounce struggling to build real follow-through. The latest move back toward $0.90–$0.92 shows price is once again testing an area that has acted as support multiple times.
Volume during the drop hit about 28.65 million SUI, which is not small. That kind of activity usually shows real distribution or forced exits rather than quiet trading. Momentum tools like MACD are trying to stabilize, but they still show weak strength, while RSI sits in a neutral zone, not yet at extreme oversold levels.

Key zones now controlling SUI price direction
Right now, everything comes down to a few clear levels. On the downside, $0.90 is the line traders are watching closely. If that level gives way with volume, the price could slide toward $0.85, and then deeper support around $0.70 becomes the next area of interest.
SUI market cap just dropped 5% to $3.67B amid a full mainnet stall – blocks halted, transactions paused, and $SUI price down 8%.

On the upside, recovery needs a clean move back above $1.00 first. Above that, $1.05 to $1.10 becomes the next resistance area where sellers have stepped in before. Without reclaiming those levels, the broader trend still leans downward.
BeinCrypto data shows the SUI price trading near $0.932, down about 4.74% in 24 hours, with volume reaching roughly $725M. The main driver behind the drop was the network outage, but general weakness across crypto markets added extra pressure at the same time.
Where Could SUI Go Next?
The next phase for SUI depends on two things: whether the network regains stability and whether buyers can defend $0.90 again. Holding that zone could give the market room for a bounce back toward $1.00.
If that level breaks, things open up toward lower support zones, and the structure starts to look more vulnerable again. The SUI price is now at a clear decision point. It’s still inside a long-term downtrend from its $4.00 peak, but the $0.90 region has acted as a repeated reaction area.
