the protocol
USDG enters a screened, shielded balance. You keep control of the keys and can withdraw your Stash.
Tins are funded in shared rounds on a 10-minute cadence; small rounds may wait up to 30 minutes. USDG and gas arrive together.
Each pull gets a new single-use wallet. Your card stays in its own tin, ready to keep or send back.
Gift a pack, keep your pull or share a hit under a season handle. Posting is always your choice.

know what stays private
Foil separates your shielded USDG balance from the single-use wallets that hold each pull. Tins and their onchain activity remain public; Foil is designed to conceal which tins belong to you. Small or unusual funding rounds offer less cover.
A tin is an ordinary single-use wallet created for a pull. It receives USDG and gas together in a shared funding round. The wallet holds the pulled card, and you control its key.
The partner marketplace vaults the physical cards represented by its tokens. Foil provides the wallet and privacy flow. Redemption and shipping remain subject to that marketplace's terms; Foil is not a grading or vaulting company.
A posted hit links that specific tin to your season handle. Redeeming a card links the tins you ship from to the identity supplied to the marketplace. A gift-card transfer is visible as a hand-off between two tins.
