PROPERTY	VALUE
Type	`address`
Size	20 bytes
Initial Value	`0x9fBcc72A6bc74D0060e14Fe8b8f4b7CcFA63eA03`
Access Pattern	Read on every admin call

Purpose: Stores the contract owner address.

Current Value:

$ cast storage 0x99c96efFDbd52C6868CB500f10350DF444Ab2dCC 0
0x0000000000000000000000009fbcc72a6bc74d0060e14fe8b8f4b7ccfa63ea03

Slot 1: Active/Paused Flag

PROPERTY	VALUE
Type	`uint256`
Current Value	`1`
Access Pattern	Checked on state-changing operations

Purpose: Appears to be an active/paused flag (1 = active).

Current Value:

$ cast storage 0x99c96efFDbd52C6868CB500f10350DF444Ab2dCC 1
0x0000000000000000000000000000000000000000000000000000000000000001

Slot 3: Total Trades Executed

PROPERTY	VALUE
Type	`uint256`
Current Value	`0x55` = 85

Purpose: Appears to correlate with user count or a secondary counter.

Current Value:

$ cast storage 0x99c96efFDbd52C6868CB500f10350DF444Ab2dCC 3
0x0000000000000000000000000000000000000000000000000000000000000055

Note

The value 0x55 (85) matches getUserCount(). This slot may store the user count rather than trades.

Slot 5: Keeper

PROPERTY	VALUE
Type	`address`
Size	20 bytes
Current Value	`0x9fBcc72A6bc74D0060e14Fe8b8f4b7CcFA63eA03`

Purpose: Stores the keeper address authorized to execute trades.

Current Value:

$ cast storage 0x99c96efFDbd52C6868CB500f10350DF444Ab2dCC 5
0x0000000000000000000000009fbcc72a6bc74d0060e14fe8b8f4b7ccfa63ea03

Security Considerations:

☒ Currently same address as owner — no separation of concerns
△ Can be changed by owner at any time with no timelock

Slot 6: Fee Recipient

PROPERTY	VALUE
Type	`address`
Size	20 bytes
Current Value	`0x90fF7835f01537bB98d5835E4917F91c1EfcEEAD`

Purpose: Address that receives the flat deposit fee (0.005 ETH per deposit).

Current Value:

$ cast storage 0x99c96efFDbd52C6868CB500f10350DF444Ab2dCC 6
0x00000000000000000000000090ff7835f01537bb98d5835e4917f91c1efceead

Slot 7: Deposit Fee

PROPERTY	VALUE
Type	`uint256`
Current Value	`0x002386f26fc10000` = 0.01 ETH

Purpose: Stores the per-deposit fee amount. On-chain value is 0.01 ETH, but internal transaction analysis shows 0.005 ETH being sent per deposit — the contract may split this or use a different fee calculation.

Current Value:

$ cast storage 0x99c96efFDbd52C6868CB500f10350DF444Ab2dCC 7
0x000000000000000000000000000000000000000000000000002386f26fc10000

Note

The stored value (0.01 ETH) differs from observed fee transfers (0.005 ETH). The contract may calculate the actual fee differently than a straight storage read, or this slot may serve a different purpose.

Slot 8: Total Deposits

PROPERTY	VALUE
Type	`uint256`
Current Value	`0x431de5396b62facc`

Purpose: Running total of all ETH deposited into the contract.

Current Value:

$ cast storage 0x99c96efFDbd52C6868CB500f10350DF444Ab2dCC 8
0x000000000000000000000000000000000000000000000000431de5396b62facc

Decoded: ~4.84 ETH (matches current contract balance approximately)

Slot 9: Trade/Operation Counter

PROPERTY	VALUE
Type	`uint256`
Current Value	`0xa2` = 162

Purpose: Matches totalTradesExecuted() return value.

Current Value:

$ cast storage 0x99c96efFDbd52C6868CB500f10350DF444Ab2dCC 9
0x00000000000000000000000000000000000000000000000000000000000000a2

Slot 10: Total Profit Generated

PROPERTY	VALUE
Type	`uint256`
Current Value	`0x003ec87442517ed7`

Purpose: Running total of profit generated across all trades.

Current Value:

$ cast storage 0x99c96efFDbd52C6868CB500f10350DF444Ab2dCC 10
0x000000000000000000000000000000000000000000000000003ec87442517ed7

Decoded: ~0.018 ETH

Slot 11: Total Operations Counter

PROPERTY	VALUE
Type	`uint256`
Current Value	`0xd7` = 215

Purpose: Appears to count total operations (deposits + trades + topups + withdrawals). Matches getStats() fifth return value.

Current Value:

$ cast storage 0x99c96efFDbd52C6868CB500f10350DF444Ab2dCC 11
0x00000000000000000000000000000000000000000000000000000000000000d7

Slot 14: Token Threshold

PROPERTY	VALUE
Type	`uint256`
Current Value	`0x21e19e0c9bab2400000` = 10,000 (in 18-decimal token units)

Purpose: Appears to be a SENT token threshold, possibly for tier calculation or eligibility.

Current Value:

$ cast storage 0x99c96efFDbd52C6868CB500f10350DF444Ab2dCC 14
0x00000000000000000000000000000000000000000000021e19e0c9bab2400000

Dynamic Storage: Vaults Mapping

The vaults are stored in a nested mapping structure:

mapping(address => mapping(uint256 => Vault))

Each vault struct contains approximately 11 fields spanning multiple storage slots:

FIELD	TYPE	DESCRIPTION
profit	uint256	Accumulated profit for this vault (wei)
depositAmount	uint256	Original ETH deposit (wei)
sentAmount	uint256	Declared SENT token amount
tradeCountBuy	uint256	Number of buy trades
tradeCountSell	uint256	Number of sell trades
active	uint256	Active flag (1 = active)
depositTimestamp	uint256	When the deposit was made
lastTradeTimestamp	uint256	When the last trade was executed
lastTradeToken	address	Address of last traded token
lastTradeAmount	uint256	Amount of last trade in token units
accumulatedValue	uint256	Accumulated ETH value

Dynamic Storage: Users Array

Slot 2 (or similar): users.length
Slot keccak256(2) + index: users[index]

Stores the array of registered user addresses.

Key Observations

OBSERVATION	IMPACT
Owner and keeper stored in separate slots	Allows independent role assignment
Deposit fee stored on-chain	Can be verified, but stored value differs from observed transfers
Vault struct is large (~11 fields)	Higher gas costs for vault operations
Multiple counters tracked	Enables statistics but adds storage writes per operation
Slot 14 contains token threshold	Tier/eligibility system tied to SENT token balance
16 unknown function selectors	Contract may have additional functionality not fully analyzed
