• 🧪 Steps to reproduce the issue : // Withdraw unlocked funds, with fresh Pyth price update
function updateAndWithdraw(
bytes[] calldata priceUpdateData
) external payable {
emit DebugString("Entered updateAndWithdraw");
uint256 fee = pyth.getUpdateFee(priceUpdateData);
emit DebugUint("Pyth update fee", fee);
pyth.updatePriceFeeds{value: fee}(priceUpdateData);
emit DebugUint("Price update data count", priceUpdateData.length);
Deposit storage dep = deposits[msg.sender];
require(dep.amount > 0, "No deposit");
emit DebugUint("Deposit amount", dep.amount);
require(dep.goals.length > 0, "No goals configured");
uint256 achievedCount = 0;
for (uint i = 0; i < dep.goals.length; i++) {
if (dep.goals[i].achieved) achievedCount++;
}
emit DebugUint("Achieved goals", achievedCount);
uint256 unlocked = (dep.amount * achievedCount) / dep.goals.length;
uint256 available = unlocked - dep.withdrawn;
emit DebugUint("Available for withdrawal", available);
require(available > 0, "Nothing to withdraw");
// Get fresh price from Pyth
PythStructs.Price memory price = pyth.getPriceUnsafe(hbarUsdPriceId);
emit DebugUint("Raw price", uint256(int256(price.price)));
emit DebugUint("Expo", uint256(int256(price.expo)));
uint256 priceValue = uint256(int256(price.price));
uint256 decimals = price.expo < 0
? uint32(-price.expo)
: uint32(price.expo);
uint256 usdValue = (available * priceValue) / (10 ** decimals);
emit DebugUint("USD value", usdValue);
dep.withdrawn += available;
(bool sent, ) = msg.sender.call{value: available}("");
require(sent, "Withdrawal transfer failed");
emit Withdrawn(msg.sender, available, usdValue);
uint256 refund = msg.value - fee;
if (refund > 0) {
(bool r, ) = msg.sender.call{value: refund}("");
if (!r) {
emit DebugString("Refund failed");
emit DebugUint("Refund amount", refund);
} else {
if (dep.withdrawn == dep.amount) {
delete deposits[msg.sender];
}
emit DebugUint("Refunded excess fee", refund);
}
}
