6.2 System Contracts
Includes built-in contracts for chain config, query, governance voting, and multisig.
6.3 SDK & Developer Support
Multi-language SDKs (Rust, Go, Solidity, C++ etc.) for reading, writing, context queries, cross-contract calls, and role identification.
6.4 Deployment & Maintenance
Standard flow: build → test → compile → upload ABI/bytecode → deploy → monitor → optional compliance auditing.
6.5 Payment Contract Marketplace (Planned)
Template library including auto-settlement, reversible payments, scheduled triggers, invoice-NFT registration, multisig custody, etc.
