VeChain will introduce a dynamic VTHO supply model linked to VET staking starting December 2025. This change, part of the Hayabusa upgrade's second phase, aims to improve fairness and decentralization by aligning rewards with network usage. The annual VTHO supply will now vary based on staking participation, replacing the previous fixed issuance of approximately 1.37 billion VTHO per year. The transition from PoA to DPoS on the testnet was completed on November 11, 2025, with mainnet activation set for December 2. A seven-day transition period will pause VTHO generation to facilitate network adaptation.
