Aptos (APT) トケノミクス

Aptos (APT) launched its mainnet on October 12, 2022, with an initial total supply of 1 billion tokens. The token utilizes 8 digits of precision, with the minimal unit referred to as an Octa. The ecosystem is designed with a focus on long-term sustainability, community growth, and a transition toward a performance-driven deflationary model.

Issuance Mechanism

The initial supply of 1 billion APT was distributed among four primary categories. While the initial supply is fixed, the network utilizes an inflationary reward system to incentivize security through staking.

• Initial Supply Distribution:
  • Community: 51.02% (510,217,359.767 APT)
  • Core Contributors: 19.00% (190,000,000.000 APT)
  • Foundation: 16.50% (165,000,000.000 APT)
  • Investors: 13.48% (134,782,640.233 APT)

As of early 2026, Aptos has proposed a significant overhaul to its issuance model. This proposal aims to shift from a high-inflation, subsidy-based model to a deflationary, revenue-driven supply. Key elements of this shift include cutting the staking reward rate by 50% (from 5.19% to 2.6%) and implementing programmatic buybacks funded by transaction fees.

Allocation and Usage Mechanism

The majority of the APT supply is designated for ecosystem development and community initiatives.

• Community and Foundation: These tokens are intended for grants, incentives, and growth initiatives. A significant portion (410.2 million APT) is held by the Aptos Foundation, while 100 million APT is held by Aptos Labs.
• Transaction Fees: Currently, all APT transaction fees are burned. However, the network has the option to revisit this through governance. A 2026 proposal suggests a tenfold increase in gas fees to support the new deflationary mechanism.
• Governance: APT holders can participate in governance by submitting and voting on Aptos Improvement Proposals (AIPs). This includes voting on blockchain parameters, core code changes, and framework module upgrades.

Incentive and Staking Mechanism

Aptos employs a Stake-for-Access (SFA) model to secure the network and incentivize participation.

• Validator Requirements: To operate a validator, a participant must stake a minimum of 1.00 million APT. There is a maximum stake limit of 50.00 million APT to prevent over-concentration of voting power.
• Staking Rewards: Validators earn inflationary APT block rewards based on their staked amount and performance (successful proposals per epoch).
• Delegation: Tokenholders can delegate as little as 10 APT to a validator. Delegators receive a share of the block rewards proportional to their stake, minus a commission set by the validator.
• Proposed Changes: Future incentives may include higher reward rates for participants who make longer-term staking commitments.

Locking and Unlocking Mechanism

Aptos utilizes a staggered vesting schedule to manage the release of tokens into the circulating supply, particularly for the team and private investors.

Validator Locking: Once a validator joins the set, their stake is locked for 30 days. This lockup period renews automatically. While a validator can request to unlock at any time, the tokens only become available once the current 30-day period expires.

Unlocking Timeline and Projections

The unlocking schedule results in periodic increases in the liquid supply. Significant unlocking events have been noted in recent years:

• Q2 2024: Approximately $562 million worth of APT was scheduled for unlock, primarily impacting team and private investor allocations.
• Q3 2025: A projected $99.4 million worth of APT is designated for Aptos Labs and private investors.
• 2026 Proposal: As part of the tokenomics pivot, the Aptos Foundation has proposed permanently locking 210 million APT tokens currently in its possession to further reduce potential sell pressure and support the deflationary shift.
