SEI rallies 30% in June as Giga upgrade testnet fuels buying pressure

Sei Network's Giga upgrade testnet completion has driven SEI to a 30% June gain, but overbought signals and long-term resistance levels temper the rally's sustainability.

SEI rose 10.6% to $0.058 on Wednesday, extending its June rally past 30% after Sei Network completed testnet deployment of its Giga scalability upgrade.

"The Giga upgrade positions Sei for greater institutional adoption by enabling parallelized transaction processing, a critical feature for high-frequency DeFi trading," Viktoras Karapetjanc, an expert at Traders Union, said. "With mainnet activation on the horizon, the market structure supports further growth."

The upgrade, which targets mainnet activation within two quarters pending security audits, introduces parallelized transaction processing and consensus optimizations designed to boost throughput for decentralized exchange order matching. SEI's capped supply of 10 billion tokens limits dilution risk, though ongoing vesting unlocks from early investor allocations could create selling pressure. The token traded above its 20-day moving average of $0.0522 but remained below the 50-day and 200-day levels at $0.0597 and $0.0777, respectively, according to TradingView data.

The rally's durability hinges on whether SEI can reclaim the $0.0583 resistance level, with a sustained breakout potentially opening a path toward the $0.0979 level seen three months ago. Failure to hold above $0.0565 support could trigger a retracement, as the Relative Strength Index at 74.6 signals overbought conditions and the Stochastic RSI flashes exhaustion warnings.

Giga upgrade targets DeFi throughput bottleneck

Sei, a layer-1 blockchain built specifically for trading applications, competes with Solana, Aptos and Sui in the race to capture decentralized exchange volume. The Giga upgrade's parallelized processing architecture aims to solve the throughput limitations that have constrained order-matching engines on general-purpose blockchains. Testnet deployment completed in early June, with mainnet activation expected within the next two quarters assuming no critical vulnerabilities emerge during auditing, according to the project's development documentation.

Analysts at BitcoinWorld modeled SEI at $0.45 to $0.75 by end-2026 and $1.50 to $3.00 by 2030 if total value locked, developer activity and cross-chain integrations follow the upgrade's adoption trajectory. Competing layer-1 networks are pursuing similar performance improvements, making Sei's differentiation critical for capturing market share.

Mixed signals beneath the surface

While the June rally reflects renewed optimism, technical indicators present a conflicting picture. The Moving Average Convergence Divergence shows strong selling pressure on higher timeframes, and the Average Directional Index indicates a weak trend despite the recent price surge. Anton Kharitonov, an expert at Traders Union, said the rebound looks fragile. "Despite the upgrade narrative, SEI faces strong headwinds unless it reclaims $0.0583 with conviction," he said.

On-chain data shows token buying pressure building over the past 48 hours, with intraday volatility at 6.40% and the price trading near session highs. The opening upside gap of approximately 5.32% suggests momentum-driven demand rather than organic accumulation, raising the risk of a "buy the rumor, sell the news" scenario post-upgrade.
