}On-chain WASM contracts handle logic execution, state transitions, and event triggers without external calls.
Every contract call is executed with absolute predictability across nodes via Stellar VM runtime.
All variable states, storage commits, and contract updates are cryptographically hashed and ledger-anchored.
Role-based access enforced via contract ID verification and multi-sig account structures.
No oracles, no custodians—only protocol-enforced state changes and contract-governed permissions.

Smart contracts interoperate across protocols using Soroban interfaces and cross-contract invocation patterns.
Execute multiple contract calls in a single ledger transaction with built-in failure rollback.
Contracts can natively enforce regulatory logic through embedded KYC/AML verifiers.
