ACT Opportunity Reconstruction

Pre-incident state (σ_B): Publicly reconstructible state of BNB Chain (chainid 56) immediately before including transaction 0x487fb71e3d2574e747c67a45971ec3966d275d0069d4f9da6d43901401f8f3c0 in block 48703546, in which LifeProtocolContract (0x42e2773508e2AE8fF9434BEA599812e28449e2Cd) holds approximately 5.2702676277683292087061e22 BEP20USDT, implements the buy/sell/buyBackReserve/currentPrice logic described in its verified source, and the DODO DPP flash-loan pool 0x6098a5638d8d7e9ed2f952d35b2b67c34ec6b476 is configured with sufficient USDT liquidity to lend 110000000000000000000000 units via flashLoan().

• Block height B: 48703546
• Adversary-crafted transaction b: 0x487fb71e3d2574e747c67a45971ec3966d275d0069d4f9da6d43901401f8f3c0 on chainid 56
• Inclusion feasibility: An unprivileged adversary controlling EOA 0x3026c4.. (or any EOA) can deploy a helper contract similar to 0xf6cee4.., then send a 0-value transaction to that contract calling the public function corresponding to selector 0x0c96fa62 with arguments (flashLoanPool=0x6098a5.., loanAmount=110000000000000000000000, loanToken=0x55d398.., token=0x19b2834f99fb9eb4164cb5b49046ec207f894197, am1=0x32, buyer=EOA); DODO's flashLoan() is permissionless and enforces only repayment within the same transaction, and LifeProtocolContract.buy/sell are public non-owner functions with no whitelists, so standard BNB Chain transaction rules suffice to include the tx at a competitive gas price.

Exploit predicate (profit):

• Reference asset: USDT
• Adversary address: 0x3026c464d3bd6ef0ced0d49e80f171b58176ce32
• Value before: 0
• Value after: 15114791884494874317000
• Value delta: 15114791884494874317000
• Valuation notes: Values are taken directly from the prestate-based BEP20USDT balance diff for tx 0x487fb7.. in artifacts/root_cause/data_collector/iter_2/tx/56/0x487fb71e3d2574e747c67a45971ec3966d275d0069d4f9da6d43901401f8f3c0/balance_diff_prestate.json, which shows LifeProtocolContract losing 15114791884494874317000 USDT and the attacker EOA gaining the same amount during this transaction, while the flash-loan pool 0x6098.. has zero net USDT delta. Gas fees are paid in BNB and are not converted to USDT here, but they are small (~0.006991929 BNB) compared to the USDT profit.

Vulnerability & Root Cause Analysis

LifeProtocol misprices LIFE relative to its USDT reserves by (a) adding the full USDT paid on buys into buyBackReserve, (b) using a circulatingSupply definition that decreases when LIFE is transferred back to the protocol, and (c) resetting currentPrice to buyBackReserve * 1e18 / circulatingSupply when buyBackReserve exceeds circulatingSupplyValue, while honoring sells at 90% of this elevated price when there is sufficient USDT on hand.

From the verified source "artifacts/root_cause/data_collector/iter_1/contract/56/0x42e2../source/src/Contract.sol", buy(uint256 lifeTokenAmount) computes totalUsdtCost = lifeTokenAmount * currentPrice / 1e18, requires it to be within [minTradeAmount, maxTradeAmount], increments buyBackReserve by totalUsdtCost, pulls that amount of USDT into the contract via UsdtToken.transferFrom, and transfers lifeTokenAmount LIFE from the protocol's inventory (remainingSupply) or from queued sell orders to the buyer. After each buy, handleRatio(totalUsdtCost) computes circulatingSupply = totalSupply - lifeToken.balanceOf(address(this)) and circulatingSupplyValue = circulatingSupply * currentPrice / 1e18; if buyBackReserve > circulatingSupplyValue it sets currentPrice = buyBackReserve * 1e18 / circulatingSupply. Sells use this currentPrice unadjusted: sell(uint256 amount) sets sellPrice = currentPrice * 90 / 100 and requiredUSDT = sellPrice * amount / 1e18, then immediately transfers amount LIFE from the seller to the protocol and requiredUSDT USDT back to the seller when UsdtToken.balanceOf(address(this)) >= requiredUSDT, while only subtracting requiredUSDT from buyBackReserve and not recomputing currentPrice.

Vulnerable components:

• LifeProtocolContract (0x42e2773508e2AE8fF9434BEA599812e28449e2Cd) :: buy(uint256 lifeTokenAmount)
• LifeProtocolContract (0x42e2773508e2AE8fF9434BEA599812e28449e2Cd) :: sell(uint256 amount)
• LifeProtocolContract (0x42e2773508e2AE8fF9434BEA599812e28449e2Cd) :: handleRatio(uint256 _amount)

Exploit preconditions:

• LifeProtocolContract must hold a large USDT reserve (on the order of 5e22 base units) so that buy() and sell() calls can be executed in sequence without hitting the minTradeAmount, maxTradeAmount, or liquidity-availability constraints.
• The attacker must be able to obtain significant USDT liquidity for a single block without bearing market risk, which is satisfied by DODO's permissionless flashLoan() on 0x6098.. lending 110000000000000000000000 USDT to 0xf6cee4.. as seen in the seed trace.
• LifeProtocol's handleRatio() must recompute currentPrice upward based on buyBackReserve and circulatingSupply after buys but must not symmetrically recompute currentPrice downward during sells; this asymmetry is present in the verified source.
• LifeProtocol's sell() must continue to treat UsdtToken.balanceOf(address(this)) as the only liquidity guard and must not recompute currentPrice downward during the sell loop; this is confirmed by the LifeProtocolContract source and the seed trace, which shows many sell(1e21) calls each paying 2343829801680218810000 USDT without any adjustment to currentPrice between sells.

Security principles violated:

• Lack of a conserved accounting invariant linking buyBackReserve, currentPrice, and actual USDT reserves, allowing book value to diverge arbitrarily from real backing.
• Failure to bound per-trade slippage or per-block price movement, enabling a flash-loan-funded attacker to drive currentPrice to extreme levels in a single transaction.
• Over-reliance on a single liquidity check (UsdtToken.balanceOf(address(this)) >= requiredUSDT) without reconciling price with reserves, breaking assumptions about redeemability and solvency.

        if (buyBackReserve > circulatingSupplyValue) {
            uint256 newPrice = (buyBackReserve.mul(1e18)).div(circulatingSupply);
            currentPrice = newPrice;
            emit PriceAdjusted(newPrice);
        }else{
            uint256 priceIncrease = calculatePriceIncrease(_amount);
            currentPrice = currentPrice.add(priceIncrease);
        }
    }

    function generateSellOrderId() internal view returns (bytes32) {

Adversary Flow Analysis

Single-tx, flash-loan-assisted exploit where a freshly deployed helper contract borrows USDT from a DODO DPP pool, drives LifeProtocol's internal price up via repeated buys, then drains USDT by selling at the elevated price and forwarding profits to the attacker EOA.

Inside the exploit transaction, 0xf6cee4.. calls DODO DPP flashLoan on 0x6098.. to borrow 110000000000000000000000 USDT, then approves LifeProtocolContract to spend its USDT and LIFE and performs multiple LifeProtocolContract.buy(1e21) calls. Each buy transfers an increasing amount of USDT from 0xf6cee4.. to LifeProtocolContract and transfers 1e21 LIFE back, increasing buyBackReserve and, via handleRatio(), pushing currentPrice higher while the contract accumulates USDT.

Evidence: artifacts/root_cause/data_collector/iter_1/contract/56/0x6098a5638d8d7e9ed2f952d35b2b67c34ec6b476/source/src/Contract.sol (flashLoan implementation); artifacts/root_cause/seed/56/0x487fb71e3d2574e747c67a45971ec3966d275d0069d4f9da6d43901401f8f3c0/trace.cast.log (LifeProtocolContract::buy calls and increasing USDT transferFrom amounts)

LifeProtocol USDT drain and flash-loan repayment

Transactions:

• BNB Chain (chainid 56), tx 0x487fb71e3d2574e747c67a45971ec3966d275d0069d4f9da6d43901401f8f3c0, block 48703546, mechanism other

After currentPrice has been raised, 0xf6cee4.. invokes LifeProtocolContract.sell(1e21) many times; each call transfers 1e21 LIFE from 0xf6cee4.. to LifeProtocolContract and 2343829801680218810000 USDT from LifeProtocolContract to 0xf6cee4.., as shown in the trace. LifeProtocolContract does not adjust currentPrice downward during these sells, so each loop yields similar USDT proceeds. 0xf6cee4.. then repays the flash-loan principal and fees to 0x6098.. and forwards the remaining USDT to the EOA, producing a net transfer of 15114791884494874317000 USDT from LifeProtocolContract to 0x3026c4.. while leaving the flash-loan pool with no net change in balance.

Impact & Losses

• Token: USDT, Amount: 15114791884494874317000

The exploit reduces LifeProtocolContract's BEP20USDT balance from 52702676277683292087061 to 37587884393188417770061 as recorded in balance_diff_prestate.json, a loss of 15114791884494874317000 base units (approximately 15.11 million USDT assuming 18 decimals). The DODO flash-loan pool 0x6098.. and other external protocols see no net balance change, indicating that this is a pure drain of LifeProtocol's reserves; subsequent user sell transactions after block 48703546 still succeed but are serviced from the diminished USDT pool, effectively socializing part of the losses to remaining participants.
