Aptos has announced significant changes to its tokenomics, including a reduction in the annualized staking reward rate from 5.19% to 2.6%. Additionally, gas fees have been increased tenfold, although stablecoin transfer costs remain low at approximately $0.00014. These changes come as the platform anticipates a rise in on-chain transaction volume and gas fee burn following the launch of Decibel DEX, with an estimated annual burn of over 32 million APT. The updated tokenomics also introduce a hard cap on the total protocol supply at 2.1 billion APT. The Aptos Foundation plans to permanently lock and stake 210 million APT. Future incentives will shift to milestone-based triggers, and a programmatic buyback program is under consideration.
