Aptos has announced significant updates to its APT token economic model, introducing a performance-driven supply mechanism. Key changes include a tenfold increase in gas fees, positioning Aptos as a higher-cost blockchain while maintaining low stablecoin transfer fees at approximately $0.00014. The token supply will be capped at 2.1 billion APT, with no new tokens minted beyond this limit once community approval is secured. The Aptos Foundation plans to reduce annualized staking rewards from 5.19% to 2.6% to incentivize long-term participation. Additionally, a new deflationary mechanism via the Decibel protocol will facilitate high-frequency trading that consumes and destroys APT. The Foundation will also permanently lock 210 million APT, ensuring these tokens remain staked and unsold. Future grants will be tied to performance milestones, and a programmatic buyback program is under consideration to capitalize on market opportunities.
