Avalanche (AVAX) rose 12.67% to $9.58 by 1:40 p.m. on September 20, briefly moving above $10 during the session, as traders anticipated the Helicon mainnet upgrade (network-wide blockchain update) scheduled for September 22. Helicon is designed to improve validator operations and efficiency on the Avalanche network. It will reduce the minimum validator staking period (required time validators lock funds) to 48 hours from 14 days, lowering the time burden associated with validator participation. The price data was reported by CoinMarketCap. The source also identifies Uk Jin.
