ADR-002: Builder Pattern Without Execution

Status: Accepted
Date: 2026-07-23
Context: Several DeFi methods (swap, mint position) return a parameter dict instead of executing immediately.
Decision: The kit uses a "build → sign → execute" pattern where methods build transaction parameters without broadcasting. This separates concerns: the Agent/API layer decides when to sign and send.
Consequences:
- ✅ User can inspect, simulate, or modify params before execution
- ❌ Extra step confuses users expecting a single "do it" call
- ❌ Some callers forget to execute the built transaction
