Hi SwiftChainn,

I'm deep in the contracts configuration files and completely set to lay down this Soroban environment baseline.

Misconfiguring your Cargo workspace profiles or omitting explicit optimization parameters when setting up a new on-chain contract can result in bloated WASM binaries that exceed Soroban’s strict ledger fee and resource limits. I’ve configured and tuned workspaces across multiple Stellar-adjacent systems before, ensuring that the compilation pipelines output highly optimized, production-ready bytecode that passes verification checks cleanly.

Thanks!
