# Lottery
> BINI ticket lottery with 60/20/10/10 revenue split. Phase 2 of the Bini App rollout.
The lottery launches in **Phase 2** of the Bini App rollout. This page documents the canonical mechanics. Live values (ticket price, draw frequency, jackpot rules) will be confirmed in the app at launch.
## What it is
A ticketed BINI lottery integrated into the Bini App. Buy tickets in BINI, watch draws, win jackpots.
The lottery is the **fourth permanent BINI sink** (sink #4 in the ecosystem) — 20% of every ticket purchase is permanently burned.
## Revenue split
Every ticket purchased with BINI splits as follows:
```
Ticket price:
├── 60% Jackpot (winners)
├── 20% Burned permanently
├── 10% Referral commissions
└── 10% Platform operations
```
| Slice | Where it goes |
| ---------------- | ------------------------------------------------------------------------ |
| **60% Jackpot** | Funds the prize pool. Eventually paid out to winners. |
| **20% Burn** | Sent to a burn address. Permanently removes BINI from circulation. |
| **10% Referral** | Paid to the referrer who introduced the ticket buyer (where applicable). |
| **10% Platform** | Operating reserve and platform development costs. |
## Why these numbers
* **60% to winners** is high enough to attract participation but leaves headroom for sinks
* **20% burn** makes the lottery a meaningful contributor to deflationary pressure (vs zero in most lotteries)
* **10% referral** pays the user-acquisition channel
* **10% platform** funds ongoing operations
## Burn projections
If the lottery sees \$V in daily ticket revenue:
```
Daily burn = V × 0.20 (in BINI)
```
| Daily ticket revenue | Daily BINI burn (at \$0.12 ref) |
| -------------------: | ------------------------------: |
| \$1,000 | 1,667 BINI |
| \$10,000 | 16,667 BINI |
| \$100,000 | 166,667 BINI |
| \$1,000,000 | 1,666,667 BINI |
At \$1M daily lottery revenue, the lottery alone burns \~600M BINI/year — comparable to the entire Year 1 emission. Realistic adoption is much lower in early phases.
## Draw mechanics (TBD)
Final draw mechanics are being finalized:
* **Frequency**: daily, weekly, both?
* **Number of winners**: single jackpot, multiple tiers?
* **Verifiability**: on-chain randomness (Chainlink VRF on BiniChain) or backend-RNG with public proof?
* **Carryover**: rolls over if no winner?
Draws will be on-chain and verifiable. Exact format announced before launch.
## Buying tickets
After Phase 2 launch:
1. Open the Bini App → Lottery tab
2. View current pot, time to next draw, your tickets
3. Choose a number (or auto-pick) and quantity
4. Confirm — pay BINI at the current ticket price
5. Wait for the draw — winners notified in-app + on-chain
Tickets cost **BINI native** (not CRS, not USBI). To play, you need on-chain BINI.
For the cheapest path to BINI, use [Bridge B](/bini-app/bini-bridge) (off-chain BINI rewards → native, gated at L7).
## Eligibility
* Open to any user with a Binibit Telegram account
* Subject to local jurisdiction restrictions (lottery legality varies by country)
## Tokenomics impact
Per [BINI Sinks](/tokenomics/bini-sinks), lottery is sink #4:
* 20% of revenue is permanent burn
* 60% jackpot eventually re-enters circulation as winnings (effectively a recycle)
* 10% referral re-enters as referrer-controlled BINI
* 10% platform stays in reserve, eventually deployed for ops
Net effect on supply: -20% of every ticket. Combined with the [DEX swap burn](/baidex/overview) and [spawn fee burn](/agentt-launchpad/overview), this creates a structural deflationary force.
