Bridge
The bridge moves assets between BSC Testnet and Super AI Chain Testnet using a self-custodied lock/mint design with a relayer — it does not depend on the BSC native cross-chain relayer.
How it works
Reverse direction burns/locks on Super and unlocks on BSC.
Two modes
- MINT_BURN — issues a new wrapped token on Super (
BridgeToken), minted on deposit and burned on withdrawal. - LOCK_UNLOCK — maps an already-deployed token on Super; the bridge holds a reserve (
depositReserve) and transfers from it.

Decimals
Token decimals can differ across chains (e.g. BSC 18-dec vs Super 6-dec stablecoins). The relayer reads decimals() on both sides and scales the amount; the signed message uses the scaled destination amount, and dust below the smallest representable unit is rejected.
Limits
Per-transfer maximums and confirmation depths are configured at deploy time (anti-reorg). Check the bridge UI for current limits.
