About LACHESIS.

A no-loss 6/42 lottery on Flare. Your deposit is always yours. The staking yield it earns is what funds the prizes, and every draw is recorded on-chain for anyone to verify.

[live] Flare · chain 14

01How it works

Deposit

Put FLR into the pooled vault. Min 100 FLR is one ticket per round. Your principal earns FTSO yield and is never used as prize money.

Yield grows the prize

FTSO delegation earns rewards roughly every 3.5 days. Only that yield funds prizes. Your deposit stays withdrawable.

Match and win

Pick 6 numbers from 1 to 42. Match 3 or more to win a share of the pool. No winners means the pot rolls over and grows.

02Key facts

No-lossEligible deposits are withdrawable anytime; the lottery never spends your principal.
Verifiable RNGDraw seed comes from 100+ independent FTSO providers, on-chain.
On-chainEvery deposit, draw and payout is written to Flare mainnet.
ImmutableNo admin backdoor over draws or prize selection.

No winners in a tier? That share stays in the pool and compounds into the next round.

04How winning numbers are chosen

Every draw uses on-chain cryptographic randomness. No single participant, not even the operator, can predict or influence the result.

01

Your deposit earns yield

Your FLR earns FTSO delegation rewards roughly every 3.5 days. Your principal is never touched; only the yield flows into the prize pool. New deposits unlock after one epoch and are withdrawable after that.

02

100+ providers contribute entropy

Every voting epoch, 100+ FTSO data providersⓘ each submit a secret random value. No provider knows what the others submitted, and no single entity, not even LACHESIS, has any influence over these values.

03

Values are combined on-chain

All contributions are aggregated by the Flare network into one verifiable random value, combined with on-chain entropy and tied cryptographically to the round id. The seed is unique, immutable, and impossible to forge after the fact.

04

6 winning numbers are drawn

From the verified seed, 6 unique numbers are drawn from 1 to 42 with a deterministic shuffle and recorded permanently on-chain. Anyone can verify the inputs, the algorithm and the result. The operator has zero influence over the outcome.

Why this matters

Even if every provider colluded (publicly visible on-chain), the additional entropy layers keep the final numbers unpredictable. LACHESIS uses Flare's native RandomNumberV2ⓘ, not a third-party oracle or a centralized feed. Randomness is a first-class primitive of the network.

05Why it's safe

✓Eligible deposits are withdrawable anytime. New deposits unlock after one epoch.
✓The operator has zero influence over draws.
✓All actions go directly on-chain. No middlemen.
✓The protocol keeps working even if the operator disappears.
✓Randomness comes from 100+ independent data providers.
✓The 10% fee applies to yield only, never to your principal.
