Ethereum's Glamsterdam Upgrade Faces Reality Check Amid Weakening DeFi Liquidity

Ethereum's upcoming Glamsterdam upgrade has entered its final testing phase. Scheduled for H2 2026, this significant update aims to improve the protocol level workings of Ethereum, boosting throughput and handling higher DeFi demand as liquidity returns to the ecosystem.

The upgrade introduces parallel transaction processing and raises the gas limit from 60 million toward 200 million, a change designed to expand network capacity and reduce pressure during periods of heavy on-chain activity. This becomes particularly interesting with the planned gas limit increase, which could significantly expand Ethereum's transaction capacity and support a more infrastructure-driven rally.

However, Ethereum faces an H2 reality check as DeFi liquidity weakens. Over the past four months, around $5.82 billion in stablecoin supply has been wiped out, highlighting a clear slowdown in capital availability across crypto markets. Tether recently burned $2.5 billion in USDT on Ethereum, reducing the network's total USDT supply to around $77 billion and further shifting stablecoin liquidity away from Ethereum.

ETH has started Q3 on a strong note, gaining 11%, but sustaining this momentum will require more than just short-term flows. A successful Glamsterdam upgrade could add a stronger fundamental narrative supporting ETH's price action, but institutional flows are adding another layer to the picture. A large institutional wallet recently transferred 63,000 ETH to Coinbase, suggesting Ethereum's recent upside may be more of a short-term relief move rather than the beginning of a sustained trend.
