Zcash rises above $500 as Ironwood shielded pool surpasses $260 million

Ironwood migration and vulnerability response bolster ZEC

Recent data from CoinGecko showed ZEC advancing from approximately $495 earlier in the day, briefly touching $520 before consolidating above $500. Zcash holders moved around $260 million in ZEC into Ironwood, which has now overtaken the previous Sapling pool in total value.

Ironwood went live on July 28 at block height 3,428,143 following the discovery of a critical vulnerability in the protocol’s Orchard shielded pool. Security researcher Taylor Hornby identified the flaw on May 29, prompting the Zcash Open Development Lab to coordinate a patch by June 2.

The vulnerability could have made it possible for a malicious actor to mint unauthorized ZEC tokens within the Orchard pool undetected. While Shielded Labs assessed the risk of exploitation as low, the inherent privacy of the pool prevented users from independently verifying that counterfeit tokens had never been issued.

Ironwood was developed to close this loophole by blocking new deposits and internal transfers in the Orchard pool. Funds can now only exit through Zcash’s established turnstile system, which caps withdrawals at the amount legitimately deposited, allowing users to independently verify ZEC’s circulating supply.

The Ironwood pool features an updated Orchard circuit, and this upgrade included further security measures such as independent audits, formal verification, and the introduction of quantum-recoverable notes under ZIP 2005.

After the announcement of the Orchard bug, ZEC experienced a sharp price drop of more than 50%. When Ironwood launched in late July, ZEC traded around $475, but recent recovery has pushed its price back above $500.

ZEC price analysis

On the daily ZEC/USDT chart, ZEC traded close to $509, with the Volume Profile indicating heavy historical trading activity in the $400 to $420 range. This area has served as a significant support level during recent swings. In late June, ZEC rebounded from about $400, surging to a July high near $570, and subsequent pullbacks have consistently held above this key zone.

The daily Supertrend indicator currently positions support at $447, meaning ZEC maintains its bullish daily structure so long as the price remains above this level. To extend gains, ZEC must clear resistance in the $516 to $520 range, after which the July resistance band from $560 to $580 may come into play.

Failure to defend the $500 threshold could see ZEC return to test $480, with further downside risk extending to the $400 to $420 high-volume area below the daily Supertrend support.

Short-term momentum mixed

On the 4-hour chart, ZEC changed hands around $509, with session VWAP at $511.59 and the upper band near $513.11. The token remains just below the VWAP, indicating buyers have not yet reclaimed control above the average session price. Short-term momentum has begun to soften following the latest upswing.

Stochastic RSI on the 4-hour timeframe showed the %K line near 77.85 and the %D line close to 87.50. The %K has slipped below the %D after both reached overbought territory, signaling a possible pullback.

ZEC would need to decisively reclaim the $511 to $513 VWAP area and break through $520 for another upward push. Sustaining these gains could target $540 and revisit resistance between $560 and $580, echoing the July advance. However, dropping below $500 would undermine the immediate bullish scenario and raise the prospects of declines toward $480 and the prominent support region below.

The latest gains partly reverse last week’s retreat from above $500, positioning ZEC for another test of range resistance while market participants monitor key technical levels and the sustained impact of Ironwood’s security enhancements.
