Prize-linked savings on Solana — your principal stays yours and withdrawable anytime, while the pooled yield pays out weekly prizes instead of trickling in as interest.
Ample brings prize-linked savings onchain — a model the UK has run nationally since 1956, where over twenty million savers hold £100 billion by choosing a shot at a real prize over a guaranteed trickle of interest. Every deposit sits in a non-custodial, audited vault built on EVK lending infrastructure (20+ independent audits, securing billions across DeFi), earning yield in institutional-grade, overcollateralized markets with no leverage and no directional bets. That yield — not the depositor's principal — flows into one shared weekly pool that pays out across four prize tiers, from a Grand Prize down to a wide base of smaller payouts reaching hundreds of depositors every week, decided by a verifiable random function and committed onchain before any claim so results can't be edited after the fact. Deposits are withdrawable any time; ticket weight is based on average balance held across the week (to prevent last-minute gaming), and consistent, long-term savers earn up to 1.91x the ticket weight of a newcomer with the same balance, with odds that keep improving after a week without a win.
