- Zcash’s Orchard pool error, which has not been detected since 2022, led to ZEC collapsing 52% to $303.
- The proposed Ironwood upgrade would allow anyone to check the maximum ZEC supply of 21 million.
- Analyst Yashu Gola warns of a rising wedge pattern, with a key support level at $314.
Zcash (ZEC) suffered one of its worst weeks in recent memory last week.
The privacy-focused cryptocurrency fell from around $635 to a low of around $303 within days after Shielded Labs, a non-profit developer on the Zcash network, She uncovered a fatal error in her Orchard-protected poolIt is the part of the system responsible for hiding transaction details.
This bug, which has not been discovered since 2022, could have allowed an attacker to mint an unlimited amount of counterfeit ZEC without being detected.
However, by Monday, June 8, ZEC had recovered a significant portion of those losses, trading at around $442 at press time, a roughly 45% recovery from the June 5 low.
The bounce came after two major developments: an emergency patch to address the vulnerability and the introduction of a new upgrade proposal called Ironwood.
However, the token is still down approximately 19.7% over seven days and 26.2% over the past 30 days, leaving plenty of room for recovery.
What does the Ironwood upgrade actually do?
The emergency correction was a coordinated effort.
Shielded Labs, the Zcash Foundation, and the Zcash Open Development Lab made the network upgrades within days of the reveal, working alongside mining pools ViaBTC and Foundry to get it done quickly.
But fixing the bug was just one step away.
On June 6, these groups formally proposed themselves Ironwood upgrade As a long-term solution to restore confidence in the supply of Zcash.
Ironwood will create an entirely new privacy pool based on the fixed code and effectively shut down the old Orchard pool, preventing any new coins from being created there.
Once activated, anyone running the Zcash software will be able to aggregate balances across old and new pools and independently verify that no more than the maximum supply of 21 million ZEC has been traded.
The upgrade can also serve as a forensic tool of sorts.
As users migrate their coins from the old pool, any counterfeit ZEC coins that may have been minted will either appear as they attempt to move or become stranded and effectively destroyed.
Shielded Labs said it believes the vulnerability was never exploited, although this has not been definitively confirmed.
The developers have not yet committed to a timeline, stating that building, testing, and coordinating the upgrade across the network will take time.
This is why the bounce may not last
While the price rebound looks sharp on paper, technical analysis is showing a warning sign.
ZEC appears to be forming a rising wedge pattern on the 4-hour chart. This pattern is characterized by higher highs and higher lows within a narrow range and often indicates that buying momentum is fading rather than strengthening.
Notably, after the rebound, ZEC struggled to establish sustained momentum above the $420-430 area, suggesting that buyers are finding it difficult to push higher decisively.
If the price breaks below the lower trend line of the wedge, the measured downside target is near $314.
This $314 level is not arbitrary. On the weekly chart, it is in line with the lower trendline of a broader ascending triangle and is located near the 0.236 Fibonacci retracement drawn from the swing high of approximately $700 to the swing low of $200.
If ZEC stabilizes above $314 during the pullback, bulls could argue that the broader structure remains intact.
But a decisive break below this level opens the door to a deeper slide towards the $250-$200 support area.
For the bulls to stay on track, ZEC needs to defend wedge support and settle $450 convincingly.
The 7-day range tells the whole story of how volatile this period was: $303.80 at the low and $635.49 at the high, which is more than $330 in one week.
The fundamental damage caused by error detection should not be underestimated either.
Zcash’s core value proposition is based on privacy, cryptographic integrity, and a stable, trustworthy supply of 21 million coins.
The vulnerability that could have silently inflated this supply strikes at the heart of what makes the asset attractive to the investor base.
Even with a correction in place and Ironwood on the table, rebuilding that confidence will require a price bounce of more than 45%.
The coming weeks will likely depend on two factors: whether Ironwood progresses from the proposal stage to the implementation stage, and whether ZEC is able to maintain key levels of technical support during that process.
