Apricot Phase One: 50% Reduction in Transaction Fees

Published by AVIX on

Phase One upgrade will activate on the Avalanche Mainnet at 10AM ET on Wednesday, March 31.

Today, we’re releasing the code for Phase One of the Apricot upgrade, which will activate at 10 a.m. EST on Friday, March 26 on the Fuji Testnet and at 10 a.m. EST on Wednesday, March 31 on the Avalanche Mainnet. This upgrade includes breaking changes, and should be adopted by all validators to ensure the continued health of the network.

When Phase One becomes active, users will start saving 50% on transaction fees when engaging with smart contracts on the C-Chain, a significant and impactful measure to support the rapid growth of DeFi activity on Avalanche. To prepare for the upcoming dynamic fees release, Phase One also includes an implementation of EIP-3298 (the removal of gas refunds for SSTORE and SELFDESTRUCT). This change preemptively inhibits the abuse of the forthcoming fee mechanism through the release of state slots.

Phase One also lays the foundation for optimizations coming in future Apricot Phases, expected to be released throughout Q2. These forthcoming upgrades will include:

  • Dynamic Fees on X/C/P chains
  • Enhanced Avalanche Native Token (ANT) Support on the C-Chain
  • Epochs, Fast Syncing, and Pruning
  • Single-Step Transfers (“Seamless Transfers”) between Chains
  • Governable Staking Parameters

Ava Labs developers will also be hosting a Clubhouse next Monday, March 29 from 1–2 p.m. ET. The session will be recorded and posted to YouTube to accommodate Android users and those without access to Clubhouse.
