Alas! Poor Singularity_Fi hath lost $413,000 after a wretched Uniswap V3 fee tier turned its oracle into a mere shadow of its former self. And lo! In the same week, a $464,000 JUDAO catastrophe befell the BNB Chain. What a time to be alive!
On the nineteenth day of January, under the guise of administrative duty, a protocol admin from Singularity_Fi, in a fit of blissful ignorance, registered six yield-token oracle routes using an absurd Uniswap V3 fee tier of 42. Pray tell, does this number ring a bell? Forsooth, it does not! The only valid fee tiers are 100, 500, 3000, and 10000-numbers that hold more wisdom than our wayward admin!
As per the esteemed DefimonAlerts on X, every call to factory.getPool() with this ludicrous tier returned naught but address(0). Thus, the direct price path broke in silence, like a thief in the night-no alarms, no reverberations, just a quiet demise!
Meanwhile, the dynBaseUSDCv3 vault on Base-bless its sweet, oblivious heart-continued its daily grind, utterly unaware of the true worth of its treasures.
The Vault Believed It Had $100, Yet Its Fortune Lay Hidden!
Though WETH fallback pools existed, they were as dry as a desert-void of liquidity! Hence, the VaultTokensLib.totalAssets() feebly counted only about $100 in idle USDC lounging within the vault. The real yield tokens? They were rendered invisible, like a magician’s trick!
Three months rolled by, like an endlessly boring play.
Then, a villainous interloper, having secured a flash loan of 100,000 USDC from Morpho, deposited it into the vault, minting nearly 99.99% of the total supply at that broken ratio. The minting went through without a hitch, as the oracle, in its naïveté, proclaimed the vault was nearly empty!
And thus came the redemption, tokens redeemed in a proportional dance against every actual token balance, completely independent of what the oracle claimed. Away went the underlying yield tokens! According to DefimonAlerts, the grand total of damages reached approximately $413,000. One can observe the transaction on Basescan, whilst the original fee configuration transaction lies on-chain, timestamped for all to see in January.
Singularity_Fi, in a moment of clarity, confirmed the incident via a Telegram post. A full post-mortem is anticipated, or so they say!
Such incidents are becoming a dismal trend! As of April 2026, crypto losses have soared past $620 million, with oracle misconfigurations leading the charge in this tragic comedy!
BNB Chain Did Not Sit Idly By!
Just two days later, another protocol, a different chain-yet the outcome was strikingly similar!
DefimonAlerts, ever vigilant, flagged a second debacle on X on the fateful day of April 28. JUDAO, that poor token trading on PancakeSwap with a reported TVL of $22.3 million, lamentably lost around $464,000 in a deflationary LP drain. How droll!
The JUDAO contract is endowed with a custom _update() transfer function, which springs into action on every sell. First, an “isBurnPair” check punishes or redistributes JUDAO equivalent to the sell size directly from the pair’s reserves if the price hath not ascended more than 5% since yestereve. Second, a sync() mining mechanism leeches roughly 2% of the pair’s JUDAO reserves to a dead address and mining rewards upon each sale. How clever, indeed!
The attacker boldly flash-loaned around 2.3 million USDT from Moolah, buying approximately 5.5 million JUDAO, before selling a portion. Both drain mechanisms activated simultaneously, like a well-rehearsed farce.
The pair’s reserves grew skewed! The remaining JUDAO swapped back for significantly more USDT than initially spent, yielding a profit of roughly $205,000 USDT plus 36 BNB. At current market prices, the BNB adds another $22,600 to this merry haul. The transaction is recorded on BSCScan, for all to behold!
Alas, the JUDAO token remains a phantom on CoinGecko, its market cap still shrouded in mystery.
The Configuration Was the True Villain!
Neither attack employed a novel stratagem! Nay, there were no bridges, no governance manipulations, nothing exotic! Just a simple typo in a fee tier and a tokenomics design that bites its own liquidity pool. Such irony!
Recall the Moonwell case on Base earlier this year, which followed a similar trajectory-a mere oracle formula error went unnoticed until it culminated in a grand loss of $1.78 million. Configurations break quietly, while exploits make their grand entrances!
The Singularity_Fi oracle contract address is publicly viewable, much to the chagrin of its guardians. The victim vault occupies a separate address on Base, and the JUDAO LP pair address on BNB Chain is marked for eternity on-chain.
DefimonAlerts has noted that the Singularity_Fi report is but preliminary. A formal post-mortem from the protocol remains eagerly anticipated-if only for the sake of our amusement!
