Description

Add BNB Chain (BSC) support for same-chain privacy. BNB Chain has the highest daily active wallets (4.32M) and strong Asia market presence.

Why BNB Chain?

• Highest DAU: 4.32M daily active wallets (vs Solana 3.23M)
• Asia market: Strong presence in Asian crypto markets
• TVL: $58B, 19% DeFi market share
• EVM compatible: Reuse M18 Solidity contract with minimal changes
• Low fees: Gas costs significantly lower than Ethereum mainnet

Implementation (Minimal Work)

1. Deploy M18 Solidity contract to BSC
2. Configure Gelato relayer for BSC (already supports BSC)
3. Integrate with PancakeSwap (BNB's Jupiter equivalent)
4. Update SDK chain configuration

Acceptance Criteria

• Solidity contract deployed to BSC testnet
• Gelato relayer working on BSC
• PancakeSwap integration for private swaps
• SDK chain config for BNB Chain
• Test coverage
