Treasury Functions

The EVVM contract includes specialized functions that can only be called by the authorized Treasury contract. These functions provide controlled access to user balance management for treasury operations such as deposits, withdrawals, and automated distributions.

Treasury Authorization Required

These functions will revert with SenderIsNotTreasury() if called by any address other than the authorized treasury contract.

addAmountToUser

Function Type: external
Function Signature: addAmountToUser(address,address,uint256)

Adds tokens to a user's balance in the EVVM system. This function is used by the treasury for deposit operations and reward distributions.

Parameters

Field	Type	Description
user	address	Address of the user to receive the balance
token	address	Address of the token contract
amount	uint256	Amount of tokens to add to the user's balance

Workflow

1. Authorization Check: Validates that msg.sender is the authorized treasury contract, reverts with SenderIsNotTreasury() if unauthorized
2. Balance Update: Directly adds the specified amount to balances[user][token] mapping
3. Immediate Effect: Balance change takes effect immediately within the EVVM system

removeAmountFromUser

Function Type: external
Function Signature: removeAmountFromUser(address,address,uint256)

Removes tokens from a user's balance in the EVVM system. This function is used by the treasury for withdrawal operations and fee deductions.

Parameters

Field	Type	Description
user	address	Address of the user to remove balance from
token	address	Address of the token contract
amount	uint256	Amount of tokens to remove from the user's balance

Workflow

1. Authorization Check: Validates that msg.sender is the authorized treasury contract, reverts with SenderIsNotTreasury() if unauthorized
2. Balance Update: Directly subtracts the specified amount from balances[user][token] mapping
3. Underflow Risk: No underflow protection - treasury must ensure sufficient balance exists (Solidity 0.8+ will revert on underflow)
4. Immediate Effect: Balance change takes effect immediately within the EVVM system
