BitSui

BitSui is a bridge connecting Bitcoin BRC-20 assets to Sui. Each user receives a dedicated BRC-20 deposit address, sends assets there and waits for block confirmation, then sees a mintable balance in the order book and triggers the mint manually. On mint, backend signers co-sign the request, the contract verifies the signatures and issues the corresponding asset on Sui. Withdrawing in reverse only requires a BRC-20 receiving address, with the bridge burning the Sui-side asset and releasing the Bitcoin-side balance.Bridge capacity is capped per asset and per chain, with excess requests queued, and each transfer produces a unique receipt that can be matched across both explorers.

It addresses the shortage of venues for BRC-20 assets by bringing Bitcoin-ecosystem tokens into Sui's throughput environment. SSBT covers governance and node collateral, with monitoring and liquidity nodes required to stake before taking part in cross-chain verification.
