What is Aptos
Aptos is a proof-of-stake layer-1 blockchain whose smart contracts are written in the Move language and whose transactions are executed in parallel. APT is its native token, used for gas, staking and governance.
Network and consensus
| Parameter | Details |
|---|---|
| Type | Layer-1 blockchain built around the Move language |
| Consensus | AptosBFT, a Byzantine fault tolerant protocol based on Jolteon, with stake-weighted votes |
| Execution | Block-STM runs transactions in parallel without declared access lists |
| Smart contracts | Move; the Move Prover formally verifies contract properties |
| Network | Mainnet chain ID 1, two-hour epochs, never wiped |
| Launched | Mainnet launched on 12 October 2022 |
Supply and issuance
| Parameter | Details |
|---|---|
| Initial supply | 1 billion APT at mainnet; 1 APT = 100,000,000 Octas |
| Maximum supply | No fixed cap: staking rewards increase total supply |
| Staking rewards | Maximum reward rate started at 7% a year, declining by 1.5% a year to a floor of 3.25% |
| Initial distribution | Community 51.02%, core contributors 19.00%, Foundation 16.50%, investors 13.48% |
| Vesting | Investors and core contributors were locked for four years from mainnet launch |
On 31 October 2026: 883,773,525 APT in circulation, 1,210,903,941 APT in total (source: Aptos token supply API (linked from aptos.dev)).
What APT is used for
- Staking with validators, whose vote weight in consensus is proportional to stake
- Voting on on-chain governance proposals through stake pools
- Paying gas and storage fees for transactions
Who develops and governs Aptos
- Governance
- On-chain voting by staked APT; Aptos Improvement Proposals (AIPs) are drafted on GitHub
- Foundation
- Aptos Foundation; it held most of the community token pool at launch
- Developer
- Aptos Labs maintains aptos-core and runs public network endpoints on behalf of the Aptos Foundation
- Open source
- aptos-core is open source under the Apache licence
History
| Date | Event |
|---|---|
| 12 October 2022 | Aptos mainnet launches with an initial supply of 1 billion APT. |
| 12 December 2024 | The Aptos Foundation updates its token supply API to report circulating supply from the start of the current month. |
| 12 October 2026 | Four years after mainnet, the lock-up of investor and core contributor tokens reaches its scheduled end. |
Security and audits
- Move contracts can be checked with the Move Prover, a formal verifier.
- The Aptos Foundation runs a bug bounty programme.
Risks and caveats
- APT has no fixed maximum supply; staking rewards add new tokens every epoch.
- Staked APT stays locked until the recurring lockup (currently 14 days) expires.
- A large share of the initial supply went to core contributors, the Foundation and investors.

How voting works
Votes are anonymous and carry no text. Each device has one vote per item; press the same button again to remove it. Cloudflare Turnstile checks that a person is voting. We keep a random device ID in a cookie and a salted hash of the IP address to limit abuse — no names, no accounts. Votes are visitors’ opinions, not investment advice.
