How Gamp works

Gamp holds deposited USDC in its own Solana wallet and records player balances in its database. Games, entries and settlement run on Gamp’s server. There is no smart-contract escrow or token-holder vote. Gamp controls the wallet, database, source retrieval and software.

Each round publishes its question, source, entry price, close time and rules. An accepted entry immediately deducts its price from your available balance. Your guess is encrypted in storage and hidden from other players until entries close. Gamp holds the decryption key and can read guesses. Entries cannot be edited or cancelled.

The server retrieves the round’s declared primary source after its snapshot time, stores the evidence and publishes the result. Later source revisions do not change an already settled round. Unavailable or questionable data is retried. No verified result by seven days after the observation deadline means a full refund without a fee. A verified absence of a qualifying event can trigger an earlier refund after the observation window.

Number and time predictions are ranked by absolute difference; location predictions use great-circle distance rounded to the nearest millimetre. Equal scores are ordered by entry number. The top 10% of entries, rounded up, win. After the round’s displayed fee, the prize pool is split with descending rank weights: with three winners, weights are 3, 2 and 1. Rounding dust goes to the first winner. Payouts and refunds are credited to Gamp balances automatically.

Deposits must be native USDC on Solana mainnet, transferred directly from the wallet you signed in with. Submit the transaction signature to verify and credit a finalized deposit. Withdrawals reserve your balance, then send USDC to that same wallet. Each request is 1–100 USDC, with a 500 USDC daily limit. Gamp pays withdrawal network fees. An uncertain transfer remains reserved while it is reconciled; it is never paid twice automatically.

Paid entries and deposits are currently closed. Browsing and wallet sign-in do not establish eligibility for a paid service. See the terms and privacy notice.
