How Gramlock works.
Product status
Explore original Telegram Gifts, collection prices and borrowing calculations. Connect Telegram and your TON wallet. Loans, deposits and withdrawals are processed manually by the operator. Applications and confirmations are recorded on the server.
Market data
Original images come directly from the Fragment CDN. Collection asking prices are read from the public TG Gifts / Fragment page, cached for five minutes. The provider refreshes collections in rotation. A fetched time is not the age of every price; individual timestamps are shown where available. Timed-sale asking prices are not buy-now floors and do not generate loan examples. If the source fails, stale readings are explicitly marked or prices are hidden.
Loan calculation
LTV is fixed at 70%, with 3, 7, 14 or 30 day terms. Daily simple interest: days 1–3 at 0.50%; 4–7 at 0.25%; 8–14 at 0.20%; 15–30 at 0.15%. Each rate applies only to its own period. No compounding. The total is rounded once to 0.01 GRAM. Fees in the calculation are zero.
GRAM denomination
Public prices use the GRAM denomination reported by the provider. Gramlock does not perform a token conversion. Production token address, network and precision must be verified before any transaction.
Telegram Mini App
The shared app includes a Telegram SDK adapter for viewport, safe areas, theme events and the native Back Button. Production needs HTTPS, bot setup, server-side initData verification, TON Connect, market and ownership providers, reviewed contracts and settlement infrastructure.
