Depositing
Exploring how the deposit function works
Using IbAlluoUSD as an example, users can call the deposit function using one of the stablecoins in the list of supported tokens.
IbAlluo.sol
1
function getListSupportedTokens() public view returns (address[] memory) {
2
return supportedTokens.values();
3
}

function deposit(address _token, uint256 _amount) external {
7
if (supportedTokens.contains(_token) == false) {
8
///Case 2, read below
9
IERC20Upgradeable(_token).safeTransferFrom(_msgSender(), address(this), _amount);
10
(, address primaryToken) = ILiquidityHandler(liquidityHandler).getAdapterCoreTokensFromIbAlluo(address(this));
11
IERC20Upgradeable(_token).safeIncreaseAllowance(exchangeAddress, _amount);
12
_amount = IExchange(exchangeAddress).exchange(_token, primaryToken, _amount, 0);
13
_token = primaryToken;
14
IERC20Upgradeable(primaryToken).safeTransfer(address(liquidityHandler), _amount);
15
} else {
16
/// Case 1, read below
17
IERC20Upgradeable(_token).safeTransferFrom(_msgSender(),address(liquidityHandler),_amount);
18
}
19
updateRatio();
20
ILiquidityHandler(liquidityHandler).deposit(_token, _amount);
21
uint256 amountIn18 = _amount * 10**(18 - AlluoERC20Upgradable(_token).decimals());
22
uint256 adjustedAmount = (amountIn18 * multiplier) / growingRatio;
23
_mint(_msgSender(), adjustedAmount);
24
emit TransferAssetValue(address(0), _msgSender(), adjustedAmount, amountIn18, growingRatio);
25
emit Deposited(_msgSender(), _token, _amount);

}
If you deposit a supported token, it is sent to our liquidity handler and then the correct amount of IbAlluos are minted to the caller.
If you deposit a non-supported token, it is exchanged for the
primaryToken for the IbAlluo through the Alluo Exchange and then the rest of the deposit process is completed.Case 3: If you deposit a non-supported token and it is not supported by the Alluo Exchange:
If the deposit token is not supported and it is not added to the Alluo Exchange, the function call will revert.
