# BINI Bridge (Bridge B)

> Move BINI from off-chain rewards to BINI native on BiniChain at 1:1, gated at Level 7.

**Bridge B** converts off-chain BINI (earned via Bini App quests, lottery winnings, or other rewards) into BINI native on BiniChain at a 1:1 ratio.

## Conversion rate

```
1 BINI off-chain  =  1 BINI native
```

Fixed 1:1, no fee on the bridge itself.

## Level gate

Bridge B unlocks at **Level 7** (105,000,000 XP).

The Level 7 gate is two levels higher than Bridge A (USBI bridge at L5) because BINI is real-value. The extra gating reduces sybil and farm-account risk against the rewards pool.

## How it differs from Bridge A

|                     | Bridge A (USBI)        | Bridge B (BINI)                           |
| ------------------- | ---------------------- | ----------------------------------------- |
| Source asset        | CRS (off-chain points) | BINI (off-chain rewards)                  |
| Target asset        | USBI (ERC-20)          | BINI native (gas)                         |
| Ratio               | 10,000 : 1             | 1 : 1                                     |
| Real value?         | Sandbox \$             | Real \$                                   |
| Level gate          | 5                      | 7                                         |
| Tied to entitlement | Yes (USBI cap)         | No (limited by earned BINI)               |
| Counts as XP?       | Yes (CRS spend)        | Bridge action itself does not generate XP |

## Once on-chain

Native BINI on BiniChain can:

* Pay gas for any BiniChain transaction
* Wrap into wBINI for [BaiDEX](/baidex/overview) liquidity provision
* Be staked on Binibit Exchange (160% APR — see [BINI Token / Staking](/bini-token/overview))
* Pay [Agent Token spawn cost](/agentt-launchpad/overview) on AgentT Launchpad
* Buy lottery tickets in the Bini App
* Be sent to other addresses

## Anti-sybil

The Level 7 gate plus monthly claim caps (subject to product confirmation) bound how much BINI flows out of the rewards pool through Bridge B.

The rewards pool itself is bounded by the [BINI emission schedule](/tokenomics/bini-emission) — 600M BINI over 4 years, then zero.

## Sandbox vs Mainnet

In the sandbox phase, off-chain BINI represents accrued rewards. Mainnet rules tighten:

* Stronger anti-sybil (KYC, IP analysis, behavioral signals)
* Possibly different gating logic (e.g. activity-based not just level-based)
* Real BINI farming via on-chain staking and LP incentives

See [Sandbox vs Mainnet rules](/tokenomics/ecosystem-overview).
