Aptos is a layer 1 proof-of-stake blockchain that launched on 17 October 2022, built by former Meta engineers who worked on the Diem project. It runs smart contracts written in the Move language and processes transactions in parallel, with block times under 50 milliseconds and fees of a fraction of a cent. APT is its native token.
What is APT used for?
APT pays the gas fee for every transaction on Aptos, and those fees are burned. Holders stake APT with validators, directly or by delegating, to help secure the network and earn rewards, and staked APT is used to vote on governance proposals. The annual staking reward rate was cut from 5.19% to 2.6% in 2026.
Aptos was founded by Mo Shaikh and Avery Ching, who worked on Meta's Diem blockchain project. After Diem was shut down in early 2022, they started Aptos Labs, which raised $200 million in a seed round led by Andreessen Horowitz (a16z) in March 2022. The nonprofit Aptos Foundation supports the network's growth.
How fast is Aptos, and how much does a transaction cost?
Aptos produces a block in under 50 milliseconds, a speed it first reached on mainnet in December 2025, and confirms transactions in under a second. It handled more than 16 million transactions in a single day in early July 2026. A governance vote raised gas prices tenfold in April 2026, but an average transaction still costs about $0.0005.
What is the Move programming language?
Move is a smart contract language first developed at Meta for the Diem project. It treats digital assets as resources that can be moved between accounts but cannot be copied or accidentally destroyed, which rules out whole classes of bugs common in other smart contract languages. Aptos also offers the Move Prover, a tool that mathematically checks whether a contract behaves as intended before it is deployed.
Is Aptos the same as Sui?
No. Both were started by former Meta engineers from the Diem project and both use versions of the Move language, but they are separate blockchains with their own tokens. Aptos uses an account-based model and has focused on finance, stablecoins and tokenized assets; Sui uses an object-centric model and has leaned toward gaming and consumer apps.
How many APT are there, and is there a maximum supply?
Since 2026, APT's total supply has been capped at 2.1 billion tokens. The cap was Governance Proposal #183, whose vote closed on 1 March 2026; before that, APT had no maximum supply. Gas fees paid in APT are burned, and the Aptos Foundation has permanently locked and staked 210 million APT. The live circulating supply is shown in the market data on this page.
What happens to APT token unlocks after October 2026?
Under Aptos's original vesting schedule, about 11.31 million APT unlocked on the 12th of each month. The core contributor and investor tranches end with the unlock on 12 October 2026. Community and Aptos Foundation tokens keep unlocking monthly until October 2032, at about 4.5 million APT a month, so monthly unlocks fall by roughly 60%.
How do I buy and store APT?
APT is listed on most large crypto exchanges. To hold it yourself, you need a self-custody wallet that supports the Aptos network; Aptos is a separate blockchain, so a wallet that supports only Bitcoin or Ethereum cannot hold APT. When you withdraw from an exchange, check that APT will be sent on the Aptos network, and keep your recovery phrase offline.
Is Aptos a good investment?
Whether APT suits you depends on your goals and risk tolerance, and this page is not financial advice. Aptos has fast technology, tokenized funds from large asset managers and a capped supply, but APT's price has fallen sharply from its January 2023 high, monthly unlocks continue until 2032, its number of active developers fell in 2025, and it competes with Solana, Sui and many other networks. Only invest what you can afford to lose, and speak to a licensed financial adviser before making investment decisions.
What is Aptos?
Aptos is a high-performance Layer-1 blockchain that uses parallel transaction execution and the Move programming language to reach block times under 50 milliseconds, with fees that are a small fraction of a cent. Launched in October 2022 by former Meta engineers, it now processes millions of transactions a day, hosts stablecoins such as USDT and USDC, and supports tokenized funds from BlackRock and Franklin Templeton. APT, its native token, pays gas fees, which are burned, and is staked to secure the network. Since a 2026 governance vote, APT's total supply is capped at 2.1 billion.
Most blockchains ask you to make a trade-off: either you get decentralization and security, or you get speed and low fees, but rarely all at once. Aptos was built from the ground up to challenge that assumption. Born from research originally developed at Meta (Facebook) for the ill-fated Diem project, Aptos has carved out a serious niche as one of the fastest and most technically sophisticated blockchains in the world.
Aptos handled more than 16 million transactions in a single day in early July 2026, at an average cost of a small fraction of a cent. It has attracted institutions such as BlackRock and Franklin Templeton to tokenize real-world assets on its network, and it has had no network-wide outage since October 2023.
This guide explains what Aptos is, how it works, why it matters, and what sets it apart from other Layer-1 blockchains.
Where Aptos Comes From
In 2019, Meta announced Libra (later renamed Diem), an ambitious plan to build a global payments network on a permissioned blockchain. It hired hundreds of engineers, developed a brand new smart contract language called Move, and built infrastructure designed to handle transactions at internet scale.
Regulators ultimately killed the Diem project in early 2022. But the engineers didn't disappear. Two of them, Mo Shaikh and Avery Ching, left Meta and founded Aptos Labs, taking much of the research, tooling, and engineering talent with them. In March 2022, they raised $200 million in a seed round led by Andreessen Horowitz (a16z). Seven months later, Aptos launched its mainnet under the name "Aptos Autumn" on 17 October 2022.
The result is a blockchain with an unusually mature technical foundation for its age, one that inherited years of research from one of the most well-funded blockchain projects in history.
The Move Programming Language
If there's one technical feature that defines Aptos, it's Move: a language purpose-built for safety and correctness.
Most blockchains use Solidity (Ethereum's language), which is powerful but has a troubled history of exploits. Reentrancy attacks, integer overflows, and logic errors have cost the crypto ecosystem billions of dollars. Solidity was designed to be expressive; safety was often an afterthought.
Move was designed with the opposite philosophy. Its core innovation is treating digital assets as first-class resources: objects that can be moved between accounts but cannot be copied or accidentally destroyed. This design makes an entire class of common exploits structurally impossible.
Aptos also ships with the Move Prover, a formal verification tool that mathematically proves whether a smart contract behaves as intended before it's deployed. This level of rigor is one reason institutions (traditional finance firms, asset managers and custody providers) have chosen Aptos over EVM-based chains when deploying tokenized assets where errors are unacceptable.
How Aptos Achieves Speed: Parallel Execution
Most blockchains process transactions one at a time. Even chains with fast block times often create bottlenecks because every transaction has to wait its turn. Aptos takes a different approach.
Block-STM: Parallel Processing Without the Usual Catch
Aptos uses a system called Block-STM (Software Transactional Memory) to execute multiple transactions simultaneously. The key engineering challenge with parallel execution is preventing conflicts: what happens if two transactions try to modify the same piece of data at the same time?
Many chains that attempt parallelism require developers to declare upfront which data their transaction will access, a major constraint that complicates development. Block-STM handles this differently: it optimistically executes transactions in parallel and then detects and resolves conflicts after the fact. Developers don't have to restructure their code or declare access lists. The system handles it automatically.
The Numbers
Theoretical throughput: over 150,000 transactions per second (TPS).
Daily activity: more than 16 million transactions in a single day in early July 2026, after a June week of 83.7 million transactions, the busiest week of the year to that point.
Block times: under 50 milliseconds since December 2025, which Aptos describes as the fastest block production of any major Layer-1 blockchain.
Average transaction fee: about $0.0005 on reported averages, still a small fraction of a cent after a governance vote raised gas prices tenfold in April 2026. That is far below the cost of a typical transaction on Ethereum's main network.
At sub-50ms block times, Aptos produces blocks faster than a human blink. Payments feel instant. Trading feels responsive. Applications behave like production software rather than experiments.
Uptime Since 2023
Aptos has had no network-wide outage since a five-hour halt in October 2023. This matters enormously for enterprise and institutional use cases where reliability is non-negotiable.
The Aptos Consensus Mechanism
Aptos uses a Proof of Stake (PoS)consensus mechanism with a Byzantine Fault Tolerant (BFT) protocol called AptosBFT, which is derived from DiemBFT, the system developed during the Meta/Diem era.
As of mid-2025, the network had 152 active validators with 877.9 million APT staked. Governance proposals require a threshold of staked APT to pass, and in March 2025, a governance vote lowered the passing threshold from 400 million APT to 300 million APT, making the network more responsive to community decisions.
Aptos's DeFi Ecosystem in 2025–2026
Explosive User Growth
Monthly active users on Aptos grew from 2.5 million in mid-2024 to consistently above 10 million throughout 2025. Average daily new addresses hit 328,000 in Q1 2025 before moderating in Q2, but the retention of existing users remained strong.
Stablecoins at Scale
By December 2025, the stablecoin market cap on Aptos reached an all-time high of $1.8 billion, nearly tripling over the year. Aptos became home to native deployments of USDT, USDC, and USDe, making it one of the most stablecoin-rich non-EVM chains in the ecosystem.
Aave V3 on Aptos
One of the most significant milestones in Aptos DeFi history was the governance-approved deployment of Aave V3 (the world's largest decentralized lending protocol) directly on Aptos. It went live in August 2025 as Aave's first-ever deployment outside an EVM chain, a testament to Aptos's technical maturity and the appeal of Move for DeFi infrastructure.
Decibel: On-Chain Trading at CEX Speed
Developed by Aptos Labs and the Decibel Foundation, Decibel is a permissionless trading engine combining spot and perpetuals trading in a unified cross-margin account. Powered by Aptos's native central limit order book (CLOB), it's designed to rival centralized exchange performance while running entirely on-chain. Decibel went live on Aptos mainnet on 26 February 2026.
Real-World Assets: Where Aptos Gets Serious
Perhaps the most compelling story in Aptos's 2025 chapter is the explosion of real-world assets (RWA) on the network.
In October 2025, BlackRock's BUIDL fund (a tokenized money market fund holding short-term U.S. Treasuries) deployed an additional $500 million in assets on Aptos, pushing the network's total RWA value to a peak of $1.2 billion. Other major participants include:
Franklin Templeton's BENJI fund: tokenized U.S. government securities
Ondo Finance's USDY: a yield-bearing stablecoin backed by treasuries
Securitize: an institutional digital asset platform contributing significant TVL
Echo Protocol: a BTCFi hub enabling Bitcoin holders to stake and deploy BTC within Aptos DeFi
Aptos entered 2025 with effectively no RWA footprint. By year's end, it ranked among the top three blockchains globally for tokenized real-world assets. That is a remarkable twelve months.
Payments and Global Reach
Aptos has leaned into its fee efficiency as a genuine payments rail. With gas-sponsored stablecoin transfers (meaning users don't need to hold APT to pay gas), Aptos enables near-frictionless payments for people who may never have interacted with a blockchain before.
A notable partnership with Yellow Card, one of Africa's largest crypto exchanges, enables low-cost, near-instant remittance payments across Africa, a region where traditional remittance fees remain among the highest in the world. This is a concrete, real-world use case where Aptos's technical properties translate directly into human benefit.
APT Tokenomics: A Major Overhaul
In early 2026, the Aptos community passed three tokenomics proposals, starting with Governance Proposal #183 (the supply cap, whose vote closed on 1 March 2026). Together they were among the most consequential decisions in the network's history, and all of them were in force by April 2026:
Hard supply cap (Proposal #183): a maximum of 2.1 billion APT, replacing a supply that previously had no cap.
Lower staking rewards (Proposal #184): the annual staking reward rate was cut from 5.19% to 2.6%, which slows the creation of new APT.
Higher gas fees (Proposal #185): gas prices rose tenfold. Gas fees paid in APT are burned, so the same activity now removes about ten times as much APT from supply, while an average transaction still costs a fraction of a cent.
Locked Foundation tokens: the Aptos Foundation permanently locked and staked 210 million APT, which it has said will never be sold or distributed.
This shift from an inflationary subsidy model to a usage-driven, deflationary model is a significant maturation of the protocol. As transaction volume grows, more APT is burned, tightening supply over time.
Under the original vesting schedule, about 11.31 million APT unlocked on the 12th of each month, split between core contributors (35%), the community (28%), private investors (25%) and the Aptos Foundation (12%). The core contributor and investor tranches end with the 12 October 2026 unlock; community and Foundation tokens keep unlocking monthly until October 2032, at about 4.5 million APT a month.
Challenges Aptos Faces
No honest assessment leaves out the headwinds.
Developer attrition is a real concern. Across the broader crypto industry, developer talent has migrated toward AI projects. Aptos has not been immune: the network has seen a meaningful decline in weekly active developers, from 108 in Q1 2025 to 74 in Q2. Fewer developers means a slower pace of new dApp creation, which could limit ecosystem expansion over time.
Competition from Solana, Sui (another Move-based chain), and emerging L2s on Ethereum remains intense. Aptos has strong technical differentiation, but winning developer and user mindshare in a crowded market is an ongoing challenge.
Aptos vs. Sui: The Move Cousins
Many people ask about the difference between Aptos and Sui, another Layer-1 built using a variant of Move by former Meta/Diem engineers. A few key distinctions:
Feature
Aptos
Sui
Move Variant
Aptos Move
Sui Move
Object Model
Account-based
Object-centric
Consensus
AptosBFT
Both chains share a heritage and a language philosophy, but they've developed distinct ecosystems and technical identities. Aptos has leaned harder into institutional and financial use cases; Sui has attracted more consumer-facing gaming and NFT projects.
How to Use Aptos
Getting started with Aptos is relatively straightforward:
Get a wallet. Choose a self-custody wallet that supports the Aptos network, and keep its recovery phrase offline. Aptos is a separate network, so a wallet that supports only Bitcoin or Ethereum cannot hold APT.
Acquire APT. The token is listed on most large crypto exchanges. Before you withdraw, check that APT will be sent on the Aptos network.
Explore DeFi. Aptos has its own decentralized exchanges and lending markets. DeFi apps carry smart contract and market risk, so read how a protocol works before you deposit funds.
Try a keyless account. Aptos supports keyless accounts, which let apps create an account for you when you sign in with an existing account such as Google, so there is no seed phrase to write down.
Conclusion
Aptos is not a blockchain that's promising future performance: it already runs with block times under 50 milliseconds, fees of a fraction of a cent, a tokenized-asset ecosystem that passed a billion dollars in 2025 and no network-wide outage since 2023. Its Move language rules out whole classes of bugs that have cost Solidity-based chains billions.
The risks are real: developer attrition and fierce competition. But the technical foundation is genuinely strong, the institutional adoption is concrete, and the tokenomics overhaul is a serious attempt to build long-term sustainability into the protocol.
For anyone building on Aptos or simply trying to understand the next generation of blockchain infrastructure, it deserves close attention. This page explains how Aptos works and is not financial advice.
