How can you deploy complex Solidity logic to PolkaVM within 48 KB?
Current field data from
@MontaQLabs indicates a 10-20x bytecode expansion when using the Revive (resolc) compiler. The primary constraint is not function count, but the instruction density of storage operations (SLOAD/SSTORE) and hash computations.
Helpful notes from their team:
⚫ Avoid keccak256 for internal keys: Use XOR-based derivation to reduce instruction sequences.
⚫ Eliminate Public Getters: Manually defining internal mappings saves ~2-3 KB per instance.
⚫ The Multi-Contract Solution: Decoupling logic from storage remains the most stable architecture for deployments with more than ~60 storage operations.
Predictable performance on Polkadot Hub requires designing for instruction overhead, not just EVM gas costs.
