Aster (ASTER) is the token of Aster, a decentralized exchange that specialises in perpetual futures, contracts that let traders bet on the price of a crypto asset with borrowed money and no expiry date. ASTER is used for governance votes and staking rewards, and is traded on most large exchanges. The project came out of the merger of two earlier protocols, Astherus and APX Finance, and is backed by YZi Labs, the investment firm formerly known as Binance Labs.
ASTER is the token, and this entry covers its origins, supply and risks. The exchange started on BNB Chain and several other networks and has since moved onto its own blockchain, Aster Chain. It is most often compared with Hyperliquid, the market leader it briefly overtook in trading volume in late 2025.
Aster in plain terms
Think of a betting shop where you can wager on whether the price of bitcoin will go up or down, and where the shop lets you bet ten or twenty times more than the cash you put down. A traditional crypto exchange runs that shop itself and holds your money. Aster tries to run the same kind of shop through software on a blockchain, so traders keep control of their funds in their own wallets and every bet is settled by code.
The ASTER token is a bit like a membership card for the shop. Holders get a say in how it is run and a share of rewards. Part of the money the shop earns from fees is used to buy ASTER back from the market, which is meant to tie the token's value to how busy the shop is.
History
APX Finance began in 2021 as ApolloX, a derivatives exchange on BNB Chain. Astherus was a yield protocol that offered tokenised versions of staked assets. YZi Labs invested in Astherus in November 2024, and the two projects merged around the end of that year. The combined platform relaunched under the Aster name in March 2025, and APX holders were later able to convert their tokens into ASTER.
The ASTER token generation event took place on 17 September 2025, with a large airdrop to early users. Trading volume rose sharply in the following weeks, and in late September 2025 Aster's daily volume passed Hyperliquid's for a time. Public comments about the project by Binance co-founder Changpeng Zhao, whose former firm YZi Labs had backed it, added to the attention. On 17 March 2026 Aster launched Aster Chain, its own layer-1 blockchain built around trading and privacy; before that the exchange had run as an application on BNB Chain, Ethereum, Solana and Arbitrum.
Supply and buybacks
ASTER has a total supply of 8 billion tokens. Of these, 53.5 percent, or 4.28 billion, were set aside for airdrops and community rewards, and about 704 million (8.8 percent of the total) unlocked at launch, with the rest released over several years under a vesting schedule. Further allocations cover the team, the treasury and ecosystem funding. Scheduled token unlocks add to the supply that can be traded.
To offset that, Aster uses part of its trading fees to buy ASTER on the open market. In December 2025 it directed up to 80 percent of platform fees into buybacks, and in June 2026 it was reported to be raising that share to nearly all fees, paired with burns of reserve tokens. Tokens bought back are paid out to holders who lock ASTER in its staking programme.
Uses
- Governance. Holders can vote on proposals about the exchange and its token, in line with the wider idea of on-chain governance.
- Staking and rewards. Locking ASTER earns a share of buyback proceeds, and ASTER is staked to help secure Aster Chain.
- Trading and listings. ASTER is listed on most large centralized exchanges and traded against stablecoins on decentralized ones.
Criticism and risks
Aster's reported volume has been questioned. On 5 October 2025 the data site DefiLlama stopped listing Aster's perpetuals volume after its founder found that the figures moved almost exactly in step with Binance's, and said wash trading, in which the same parties trade with themselves to inflate numbers, could not be ruled out because Aster did not publish order-level data. ASTER fell more than 10 percent on the news. Independent analysts reached different estimates of how much activity was artificial.
Other risks are typical of the sector. Perpetuals trading with high leverage can wipe out a trader's deposit in minutes, and leveraged positions can be closed automatically in sharp moves, much like a margin call at a broker. The token's value depends heavily on unlock schedules, buyback policy and the close links to Binance's circle, which critics see as a concentration of influence. Decentralized exchanges also face growing regulatory scrutiny, as many offer services that would require a licence if run by a centralized exchange.
