Aster, the decentralized perpetuals exchange backed by YZi Labs, has reimbursed traders who suffered unexpected losses after a sudden price anomaly in its XPL perpetual contract. The glitch, which briefly sent the token’s price soaring far above market levels, sparked forced liquidations before being swiftly resolved.
The issue unfolded late Thursday around 11 p.m. UTC, when Aster’s XPL perpetual pair surged past $4—while the token was trading near $1.30 on other exchanges. In a statement on X, Aster reassured users that “all funds are SAFU” and promised to cover any losses caused by the abnormal movement.
We are aware of abnormal price movements on the XPL perpetual trading pair. Rest assured, all user funds are SAFU. We are conducting a full review and will compensate any affected users for losses.

Within an hour, the exchange confirmed the problem had been fixed and began compensating affected traders. Liquidation losses were reimbursed in USDT, sent directly to users’ wallets, and the process was completed within three hours. A second round of payments later covered associated trading and liquidation fees.
What Caused the Glitch?
Some community members suggested the issue stemmed from Aster’s transition of the XPL market from pre-launch to live trading. According to user speculation, safeguards that artificially fixed prices during testing may have been lifted before the system was properly synced with real-time data. This mismatch may have triggered the temporary spike.
The issue on the XPL perpetual trading pair has been fully resolved.

Aster has not confirmed these claims but said it is conducting a full investigation and will share updates once available. The total amount reimbursed has not been disclosed, though traders estimate losses could be in the millions.

Plasma Launch and Aster’s Growth
The incident coincided with the mainnet launch of Plasma, a stablecoin-focused Layer 1 blockchain, and the debut of its native XPL token. Plasma entered the market with over $2 billion in stablecoin total value locked (TVL), immediately ranking among the top 10 blockchains by stablecoin liquidity. The new token also saw its fully diluted valuation quickly exceed $12 billion.
For Aster, the event comes during a period of rapid growth. Since its own token launch earlier this month, the exchange’s ASTER token skyrocketed from a $560 million fully diluted valuation at generation to over $15 billion within days. The platform has recently surpassed rival Hyperliquid in daily perpetuals trading volume, signaling a fast-rising presence in the decentralized derivatives market.
Unlike most on-chain perpetual exchanges, Aster distinguishes itself with a “hidden orders” feature that lets traders place invisible limit orders, adding a unique layer of privacy and strategy to its trading environment.
The Bottom Line
While the glitch rattled confidence in the XPL launch, Aster’s quick response and full reimbursement helped calm concerns among traders. As Plasma and Aster continue to expand at breakneck speed, the incident serves as a reminder of both the opportunities and risks that come with operating at the frontier of decentralized finance.
