How signing actually works
Bitcoin, Dogecoin, TRON and XRP wallets sign through dedicated key-management infrastructure under strict policy controls; EVM wallets are either delivered the same way or connected directly from a wallet you already control.
Ten chains, one model
Ethereum, Base, Arbitrum, Avalanche, Polygon, Optimism, Bitcoin, Dogecoin, TRON and XRP all follow the same non-custodial principle — no exception carved out for a \"convenience\" custodial wallet.
You can always leave
Because wallets are non-custodial, moving your assets elsewhere is always just a transaction — never a support ticket or a withdrawal review.
No shortcuts around it
There's no internal system that can move your crypto without your own signature — including for GEF's or its Digital Asset Partner's own staff.
