Aptos

What is Aptos?

Aptos is a proof-of-stake blockchain launched in October 2022 by Aptos Labs, a company founded by engineers from Meta's Diem project. It runs smart contracts written in the Move language and executes many transactions in parallel to keep fees low. APT is the native coin used for fees, staking and governance.

What it’s used for

People use Aptos for stablecoin transfers, decentralized trading and lending, and some tokenized-asset products. APT holders delegate to validators to earn staking rewards and can vote on on-chain governance proposals. Activity has been uneven: transaction counts have been high, but some institutional products, such as Ondo's USDY, have pulled back from the chain in 2026.

How Aptos works

Aptos runs a proof-of-stake network where validators stake APT and take turns proposing blocks under a Byzantine fault-tolerant consensus protocol, a design that keeps working even if some validators misbehave, descended from Meta's Diem research. Holders who do not run validators can delegate APT to them and share in rewards. Blocks finalize in under a second in normal conditions, so payments settle almost immediately.

Its execution engine, Block-STM, runs transactions in parallel by optimistically assuming they will not conflict, then re-running only the ones that do. This lets Aptos use many processor cores at once without developers having to declare in advance which accounts each transaction touches. Fees are paid in APT and have generally stayed at a fraction of a cent, though they rise when the network is busy.

Smart contracts on Aptos are written in Move, a language designed to treat digital assets as resources that cannot be copied or dropped by accident. Aptos also supports features such as keyless accounts that let people sign in with an existing web login instead of managing a seed phrase, which can make onboarding easier but adds reliance on those login providers.

Key moments

1. 2021Former Meta Diem engineers Mo Shaikh and Avery Ching found Aptos Labs.
2. 2022Aptos mainnet and the APT token launch on October 17.
3. 2023The network halts for about five hours in October, around its first anniversary.
4. 2026Governance caps total supply at 2.1 billion APT in March; in October the CEO publicly denies rumors that the chain will shut down.

Supply

APT launched with 1 billion tokens and grew through staking rewards with no limit until March 2026, when governance set a hard cap of 2.1 billion APT and staking rewards were cut roughly in half. Large allocations to the foundation, community programs, core contributors and investors unlock on multi-year schedules, which steadily adds to circulating supply.

Risks to understand

• Unlock pressure: regular token releases to insiders and investors increase circulating supply.
• Ecosystem durability: some institutional partners have reduced their presence on Aptos, and public rumors about the chain's future surfaced in October 2026, which the company denied.
• Competition: Sui, Solana and other fast chains compete for the same developers and users.
• Concentrated influence: Aptos Labs and the foundation hold large stakes and lead most protocol changes.
• Price volatility: APT has declined steeply from its past highs and can move sharply.
