Short answer
At launch, trading runs from the DYOR wallet created when you sign in. You can move funds freely between it and any other Solana wallet you own.
The DYOR wallet is what lets rug checks, transaction inspection and copy limits work end to end. To use funds from another wallet, send SOL or USDC on Solana from that wallet to your DYOR address.
Going the other way, you can send funds back out at any time, or export your DYOR wallet's key and use it in another compatible Solana app.

Every token on DYOR comes with a rug check, and every trader with what their copiers actually made.
