Withdrawals
To your own wallet, whenever you like.
From the exchange
Press Withdraw, enter an amount and confirm with your trading key. The withdrawal is included in the next block; once that block is proven and settled on STRATO, the USDλ is paid to your owner address. Open positions must be covered by the collateral that remains — the ticket will tell you how much is free to withdraw.
To another chain
USDλ on STRATO can be redeemed for USDC on Ethereum, Base or Linea through the bridge. The vault on the destination chain releases USDC against the proven redemption; you pay that chain's gas.
If the exchange stopped
Withdrawals normally go through the exchange's blocks. If the exchange ever stopped producing them, you would not be stuck: the settlement contract accepts a proof of your balance against the last settled state and pays your owner address directly. Open positions are valued at the last mark, and anyone can submit the proof on your behalf. See Forced Exit.
