Single-Chain Design Rationale

All AsiliChain smart contracts deploy on Mantle. No cross-chain bridge. No CCIP. BatchToken and LendingVault share the same chain and communicate via direct contract calls.

What was eliminated	What it cost	What was gained
Cross-chain bridge (previously considered)	High — bridge failures were the #1 complex failure mode	BatchToken → LendingVault: direct on-chain read
Second chain deployment	Medium — double audit scope, double RPC config	One audit · one explorer · one gas token
Annual cooperative gas budget	~$307/yr with bridge fees	~$7/yr — 97% reduction
