Ethereum to Shut Down Holesky Testnet After Fusaka Upgrade
Ethereum developers announced the shutdown of the Holesky testnet, the largest public testing ground, set for two weeks after the Fusaka upgrade in November. Launched in 2023, Holesky was intended to stress-test Ethereum’s proof-of-stake infrastructure but faced issues with inactivity leaks and offline validators.
Key points:
- Holesky will be decommissioned to improve developer feedback loops.
- The new testnet, Hoodi, will launch in March 2025, supporting all Pectra features.
- Sepolia remains the primary testnet for dApps, while Ephemery offers quick-reset validator cycles.
Network activity is rising, with 19.45 million active addresses recorded in August 2025, the highest since May 2021. Institutional interest is increasing, highlighted by BitMine holding 1.71 million ETH and BlackRock’s Ethereum ETF attracting $314 million on August 25.
Ethereum is transitioning from an accumulation phase into a bull run, with $4,520 as a key resistance level. A breakout could lead to values exceeding $4,800 amid favorable macro conditions and historical Q4 strength.
