Supported Chains
All chains connected to sBridge: asset types and proof methods
sBridge connects SBChain to external blockchains using chain-specific Merkle proof verification. Each supported chain has a corresponding proof method that SBChain consensus nodes verify independently on-chain.
Chain Reference
| Chain | Asset Types | Proof Method |
|---|---|---|
| Ethereum | ERC-20, ETH | Merkle-Patricia trie proof |
| Solana | SPL tokens, SOL | Merkle tree inclusion proof |
| Bitcoin | BTC | SPV Merkle proof |
| Tron | TRC-20, TRX | Merkle block proof |
| SBChain | SBT, BTS, SbAssets, RQRX | Native SBChain block proof |
Chain Integration Requirements
- A deterministic Merkle or SPV proof scheme that SBChain nodes can verify
- A lock/burn contract or address on the source chain that gates asset movement
- 2MPC signing support for the chain's native key scheme (ECDSA secp256k1, Ed25519, or native)
- A light client or block header relay mechanism so SBChain can track source chain state
