Win whole blocks.
Never lose your stake.
Never lose. Always play.
Your stake earns tickets. Real Solana blocks decide winners. Principal is never at risk.
Every block is watched live.
A preview of the in-app slot tape — real validator blocks streaming in, tier-flared the instant they land.
Three steps. Nothing simulated.
Deposit SOL
Connect a wallet and deposit into the stake pool. No deposit fee, no minimum lock. You receive a liquid staking token that represents your position 1:1.
Earn tickets every epoch
Your stake earns draw tickets automatically — 1 SOL staked ≈ 1 ticket, with a small multiplier for staying in. More tickets, more draws you're entered into.
Blocks land, winners revealed
As real validator blocks land on-chain, draws resolve against them. Wins show up instantly; principal keeps earning and stays yours the whole time.
honest fine printWithdraw any time, back to SOL — a flat 0.3% withdrawal fee applies, and nothing else.
Nothing to grind. Nothing to hide.
The house never touches outcomes. Randomness is fixed before anyone — us included — could influence it.
Randomness is committed before the epoch
Every epoch's draw seed is generated and committed on-chain before a single eligible block can land — nobody can pick a favorable outcome after the fact, because the commitment already fixes it.
Revealed only after each window closes
Sub-seeds for each leader window stay hidden until seconds after that window's last block lands. During the window, no one — including us — can compute who wins.
Block contents can never influence who wins
Winner selection never depends on a block's reward or contents. That's deliberate: it removes any incentive for a block producer to shape a block to change an outcome.
Every draw is independently verifiable
Seed, snapshot root, and derivation logic are published per epoch against an open-source verifier. Anyone can re-run a draw and check the winner themselves.
“Verify this draw” ships on every win — the same derivation anyone can re-run from public data.
Four ways a block can pay you.
Common
The steady drip — small prizes on nearly every eligible block, scaled to that block's reward.
Every leader windowRare
A handful of times a day, a block lands far above the validator's trailing average reward.

Pre-designated, VRF-selected slotProgressive Jackpot
Unpredictable and organic — funded by a share of the prize budget plus unclaimed prizes.
Any block clears a dynamic thresholdA published rate, not a marketing number.
Published prize fund rate, expressed as annualized yield on staked SOL. It’s a published, adjustable parameter — reductions require 30 days’ notice. Premium Bonds figure is the publicly stated prize fund rate at time of writing, shown as a category benchmark, not a guarantee of comparable returns.
Same category. Different chain.
Prize-linked savings is a decades-old, well-understood category — Premium Bonds alone hold tens of billions in principal that never leaves savers’ hands. Slotto runs the same idea on Solana: your principal stays redeemable, and only the yield it would otherwise earn funds the prizes.
Straight answers.
Is my SOL safe?
Your principal is always redeemable. Deposits sit in a standard, audited-pattern stake pool — the same category of program securing billions across Solana — and nothing about the prize mechanic touches your underlying stake. Withdraw at any epoch boundary, minus the flat 0.3% fee.
Where do prizes come from?
Entirely from staking yield the pool would otherwise keep — never from other users' deposits or losses. The pool forfeits a published share of its staking yield (the prize fund rate) plus, for the Epic tier, the full reward of blocks that genuinely belong to the pool's stake.
How are winners picked?
A random seed is committed on-chain before each epoch begins, and per-window sub-seeds are only revealed seconds after that window's blocks land. Winner selection never depends on a block's reward or contents, so it can't be steered after the fact — see “Why it's fair” above, and every draw links to an independent verifier.
What does it cost?
Nothing to deposit. Withdrawals carry a flat 0.3% fee, universal for every user — that's the only cost, ever.
Why can't I use it in the UK, US, or some other regions?
Savings and promotions rules differ a lot by jurisdiction, and we'd rather geoblock properly than launch into regions where the category isn't yet clearly resolved. The UK, US, and a small list of other regions are restricted at launch while we work through this; that list may shrink over time.
How is this different from games of chance?
No consideration is paid to enter a draw — you're not risking anything beyond the opportunity cost of yield you'd otherwise earn. Prizes come solely from forfeited staking yield, never from other participants, and your principal is 100% redeemable at any time. That combination is what puts Slotto in the prize-linked savings category, alongside products like Premium Bonds, rather than a game of chance.
Can I lose my principal?
No. The entire premise is no-loss: draws affect only the prize budget, never your deposited principal, and withdrawal is available at any epoch boundary regardless of what any draw has done.
When is iOS coming?
Android and the Solana dApp Store (Seeker) come first, since that's where our launch wallet and mobile flow live. iOS is on the roadmap — join the waitlist below and we'll email you the moment it opens.
