MY CONTRIBUTION
Scope and ownership
I designed an intent-based settlement flow around SIP-018 signatures, encrypted payment instructions, nonce and expiry checks, relayer execution, and bounded asset movement.
TECHNICAL EVIDENCE
What the work includes
- SIP-018 structured intents bound to the target chain
- Encrypted instructions with relayer-assisted execution
- Replay protection through nonce and expiry constraints
- Explicit threat model: metadata reduction, not amount or recipient secrecy
