Minimum deposit: 1 USDG
Pre-configured stock tokens: AAPL, TSLA, NVDA, MSFT, GOOGL (more can be added by the owner via setStockToken)

WithdrawRouter details#

After Lighter settles a USDG withdrawal to your wallet, call the WithdrawRouter to swap USDG back into a supported stock token. Pre-configured targets match the Router's stock list.

The BuybackVault ships separately once the $HPERP token launches. It is not part of the initial trading platform deployment.
