Three bridges total

Bridge A and B are off-chain ↔ on-chain (within the Binibit ecosystem). The cross-chain bridge connects BiniChain to Ethereum.

​
Bridge A — CRS to USBI

Detail: Tokenomics → USBI Bridge, Bini App → USBI Bridge. Summary:
  • Convert off-chain Crystals (CRS) earned in Bini App into on-chain USBI ERC-20
  • Fixed rate: 10,000 CRS = 1 USBI
  • Gated at Level 5 (50M XP)
  • USBI used in BaiDEX pools as LP
The Bridge A contract on BiniChain mints USBI when off-chain CRS is consumed. The Bini App backend signs the redemption request; the contract verifies and mints.

​
Bridge B — BINI off-chain to native

Detail: Tokenomics → BINI Bridge, Bini App → BINI Bridge. Summary:
  • Convert off-chain BINI rewards (quest wins, lottery, grants) into native BINI on BiniChain
  • Fixed 1:1 ratio
  • Gated at Level 7 (105M XP)
  • Native BINI used for gas, staking (after withdrawal to Ethereum), pool participation
The Bridge B contract on BiniChain transfers native BINI from the Rewards pool reserve when off-chain BINI is consumed. The Bini App backend signs; the contract verifies and transfers.

​
Cross-chain bridge — Ethereum ↔ BiniChain

For users moving BINI between Ethereum (ERC-20) and BiniChain (native):
Mechanism (TBD pending team finalization):
  • Lock-and-mint: lock BINI on origin chain, mint on destination
  • Burn-and-mint: burn on origin, mint on destination (more capital-efficient but trusts the bridge contracts)
The exact mechanism + bridge contract addresses publish before mainnet. For now, the canonical path for cross-chain users is via Binibit Exchange (which handles the bridge as part of withdrawals).

​
Anti-sybil

Bridges B and A both have anti-sybil designs: The L7 gate on Bridge B is intentionally high — BINI is real-value, so the gate has to filter out farm accounts.

​
Bridge security

All bridges are smart contracts with:
  • Audited code (audit firm TBD pre-mainnet)
  • Multi-sig admin (no single key controls minting/locking)
  • Emergency pause (can halt withdrawals if exploit detected)
  • Time-delayed governance for parameter changes
  • On-chain logs for every action
The bridge contracts custody real BINI (in the lock-and-mint case). Bridge security is the most critical security concern in the ecosystem.
