The Binibit ecosystem has **eight BINI sinks** that consume, burn, or lock BINI. Combined with the [fixed 4-year emission schedule](/tokenomics/bini-emission), they keep the long-term supply curve sustainable. ## The eight sinks | # | Sink | Mechanism | Permanent? | | - | --------------- | --------------------------------------------------------------------------------------- | ------------- | | 1 | Gas | BiniChain transactions burn BINI as gas (or pay validators, depending on chain config) | Yes / partial | | 2 | Staking | BINI locked in staking packages on Binibit Exchange (160% APR, 30/90/180/360-day tiers) | Locked | | 3 | DEX trade burn | 0.25% of every BaiDEX swap is burned permanently | **Yes** | | 4 | Lottery burn | 20% of every BINI lottery ticket is burned permanently | **Yes** | | 5 | Spawn fee | Agent Token spawn cost is paid in BINI and burned | **Yes** | | 6 | Premium / boost | Token visibility boosts on AgentT Launchpad consume BINI | Yes / partial | | 7 | Bridge gas | Bridges A and B execute on BiniChain → consume BINI gas | Yes / partial | | 8 | LP locking | wBINI side of BaiDEX pools is locked while LP position is open | Locked | ## Permanent burns Three sinks are explicitly permanent — BINI is sent to a burn address with no recovery: ``` BaiDEX swap burn: 0.25% × swap volume Lottery burn: 20% × ticket revenue Spawn fee burn: 100% × spawn cost (per Agent Token) ``` These three together create the deflationary pressure that offsets the emission schedule. ## BaiDEX swap burn (sink #3) Every swap on BaiDEX charges a **1.00% total fee**, split: ``` Total fee: 1.00% (100 BPS) ├── 0.50% LP providers (50 BPS) ├── 0.25% Burned (25 BPS) — permanent burn └── 0.25% Referrer (25 BPS) — or treasury if no referrer ``` The 0.25% burn applies to **every swap**, regardless of pool type or token traded. As DEX volume grows, burn rate scales linearly with volume. See [BaiDEX → Fees](/baidex/overview). ## Lottery burn (sink #4) The Bini App lottery distributes ticket revenue: ``` Ticket bought with BINI: ├── 60% Jackpot (winners) ├── 20% Burned permanently ├── 10% Referral commissions └── 10% Platform operations ``` Lottery launches in Phase 2 of the Bini App rollout. See [Bini App / Lottery](/bini-app/overview). ## Spawn fee burn (sink #5) Every Agent Token spawned via AgentT Launchpad pays a **fixed BINI fee**, fully burned. The exact spawn cost is being finalized by the team. This sink scales with Launchpad adoption — more Agent Tokens spawned means more BINI burned. See [AgentT Launchpad](/agentt-launchpad/overview). ## Locked vs burned | Type | What happens to BINI | | ---------- | ---------------------------------------------------------------------------------------------- | | **Burned** | Sent to burn address. Gone forever. Reduces circulating supply permanently. | | **Locked** | Held in a contract (staking, LP). Cannot trade or move. Returns to circulation when withdrawn. | Locked BINI reduces effective float (sell pressure) but does not reduce total supply. Burned BINI does both. ## Long-term supply trajectory Combining emission and sinks: ``` Year 1-4: +210M, +180M, +120M, +90M (emission) Year 1-∞: -X% per year (cumulative burns) Year 5+: 0 emission, only burns ``` After year 4, the supply curve is **monotonically decreasing**. The exact rate depends on DEX volume, lottery activity, and Launchpad spawn count — all of which scale with usage. ## Anti-farming protections Sinks pair with [Bridge B Level 7 gate](/tokenomics/bini-bridge) and monthly claim caps to prevent over-extraction from the rewards pool. The combination — **gated source + multiple sinks** — is what makes the long-term economy work. ## Related The supply side: 4-year emission schedule Where the 0.25% burn comes from Where the 20% lottery burn comes from Spawn cost and boost fees
