Round lifecycle

A stage advances only after its corresponding on-chain state is confirmed.

  1. UpcomingSales

    The OPEN state allows contract-quoted ticket purchases.

  2. UpcomingClosing

    An authorized administrator closes sales by starting the draw process.

  3. UpcomingChainlink VRF

    The fixed ticket set waits for one verifiable randomness request.

  4. UpcomingFinalization

    Accepted randomness is converted into ten ordered winning ticket IDs.

  5. UpcomingPrize claims

    Winners claim available prizes from the wallet that owns each ticket.

Seren never asks for a seed phrase or private key.

Admin model

Authorized admins start the draw; the contract enforces its state transitions.

  • The target pool is informational and does not trigger a draw.
  • After requestDraw, ticket sales are closed and the ticket set is fixed.
  • The round snapshot records one accepted VRF request for the draw.

Seren never asks for a seed phrase or private key.

A direct POL transfer to the contract does not replace buying through the designated function.

How Seren Lottery Chain works

The interface explains every step while the contract remains the source of truth for prices, round status and results.

01

Connect on Polygon

Choose an injected wallet or WalletConnect and switch to Polygon Mainnet.

02

Choose 1–100 tickets

Select a quantity, optional referral credits and a referrer on your first purchase.

03

Approve the exact quote

The app simulates the contract call and asks your wallet to confirm the current quoted payment.

04

Verify and claim

Chainlink VRF supplies randomness; finalized winners claim prizes from their own wallet.

Ten winning positions

More ways for a ticket to win

Each finalized round selects ten unique winning ticket IDs. The contract records the winner, ticket ID, exact prize and claim status for every position.

Ten unique ticket IDs are selected, not necessarily ten different wallet addresses.

One wallet can win more than once when it owns multiple selected tickets.

01

1st place receives the largest contract-calculated share

02–10

Places 2–10 share the remaining prize allocation

Exact payouts are read from finalized on-chain results; the target pool is informational and does not trigger a draw.

+
Referral credits

Bring a participant, unlock future value

A valid referrer can be set only on a wallet’s first purchase and becomes permanent. Credits earned through the contract can reduce the price of eligible tickets.

  • Referrer must be a previous participant
  • Self-referral is rejected
  • One credit can buy one ticket at half price
  • The contract validates every credit used
Questions, answered

Frequently asked questions

Understand the mechanics and risks before connecting a wallet.

What is Seren Lottery Chain?

It is a smart-contract lottery on Polygon where ticket purchases, draw state, winners and claims are verifiable on-chain.

Which network do I need?

Polygon Mainnet, chain ID 137. The app can request a network switch from a compatible wallet.

How is the ticket price determined?

The interface reads the current ticket price and an exact purchase quote from the verified contract.

How many tickets can I buy?

From 1 to 100 tickets in one confirmed purchase, subject to the current contract state.

Does reaching the target pool start the draw?

No. The target is informational. An authorized administrator starts the draw according to the contract process.

How is randomness generated?

The contract uses Chainlink VRF v2.5 to request verifiable randomness for the round.

How many winners are there?

Ten unique ticket IDs are selected for a finalized round.

Can one wallet win more than once?

Yes. A wallet holding multiple selected ticket IDs can occupy more than one winning position.

Are prizes transferred automatically?

No. A winner claims an available prize from the wallet that owns the winning ticket.

How does the referral program work?

A previous participant can be set as referrer on the first purchase; eligible activity can grant contract-managed credits.

Can I change my referrer?

No. Once registered by the first purchase, the referrer is permanent for that wallet.

What happens if my wallet is on the wrong network?

Live contract actions remain unavailable until the wallet switches to Polygon Mainnet.

Is participation an investment?

No. Lottery participation is risky, POL spent may be lost and no return or profit is guaranteed.
