SAND Bridge Exploit Compensation Details Released
The Sandbox (SAND)

bitcoinethereumnews.com reports that The Sandbox will compensate holders of SAND bridged to Base or BNB Smart Chain with a one-for-one payout in SAND on Ethereum, funded from the company's treasury without minting new tokens. The attack exploited a configuration flaw on August 21, 2026, allowing an attacker to become the sole validator and issue unbacked tokens on Base block 50,283,176 and BNB Smart Chain block 117,321,965. The Sandbox permanently shut down the affected contracts the following morning, freezing bridged tokens while leaving SAND on Ethereum and Polygon untouched.
Compensation is based on a snapshot taken immediately before the first unauthorized mint, meaning the owed amount is fixed regardless of subsequent price changes or actions. More than 72 percent of eligible holdings are held at two centralised exchanges, which will pay customers directly without requiring individual claims. Self-custody holders must file a claim, which attaches to the specific wallet address rather than the person, and payouts occur on Ethereum, requiring Ether for transaction fees.
The claim window opens approximately within two weeks, though no fixed end date has been set yet. The operator confirmed that the total damage represents just under 0.5 percent of the three billion maximum supply.
How the market reacted
Whalio's own Binance spot order flow for SAND, measured when this story was written up on 5 September 2026. Not the outlet's figures.
Whalio’s Binance spot data for SAND shows a price of $0.03925 with a 24-hour buy ratio of 50.3%, indicating balanced trading activity over the full day. Short-term momentum is stronger, with the 1-hour buy ratio at 62.6% and the 4-hour ratio at 58.6%, suggesting that buying pressure is currently building relative to the daily average. Volume deltas support this shift, showing positive inflows of $11,557 in the last hour and $18,317 over four hours, compared to a modest $5,128 for the 24-hour period. The cumulative volume delta for the day closed at +$225,579, with net buying occurring in 22 of the last 24 hours. This indicates that recent trades have been predominantly aggressive, with buyers outweighing sellers in the immediate term.
The latest daily buy ratio of 50.3% sits at the 54th percentile of the last 281 days, against a median of 50.0% - ordinary for this coin.
Was that an ordinary day?
The same Binance spot measurements for SAND, averaged over the days leading up to the story.
Over the preceding week, SAND averaged a 49.0% buy ratio, meaning today’s 24-hour ratio of 50.3% is slightly above the weekly norm by 1.3 points. However, trading volume has been lighter, with today’s spot volume at $865,449 representing only 0.69 times the weekly average. While the coin saw net buying on three of the last seven days, the current day’s activity reflects a modest increase in buyer conviction despite lower overall volume. The price has remained stable, with an 8-day change of just +0.1%, and the total 8-day volume delta sits at +$111,822. This suggests that while short-term buying has intensified, the broader weekly trend remains subdued and consistent with recent patterns.
