Description
What does this contribution do?
DevalGuard is the first parametric devaluation insurance protocol on any blockchain. Users pay a small premium in ADA and choose a devaluation threshold (5-20%). If the exchange rate crosses that threshold during the coverage period, the smart contract automatically pays out — no claims process, no intermediaries.
The system includes:
@pythnetwork/pyth-lazer-cardano-jsHow does it integrate with Pyth?
Pyth is the heart of the protocol. Every core operation depends on Pyth's price feed:
Integration uses the withdraw-script verification pattern (Pyth Pro/Lazer on Cardano):

In Argentina, 1 in 3 people use crypto to hedge devaluation. But the only option is converting all savings to stablecoins. DevalGuard offers an insurance alternative — pay a small premium and get automatic coverage. No DeFi protocol on any chain offers this today.

Notes for Reviewers
This creates the first
/lazer/cardano/directory in the repository. The project demonstrates deep Pyth integration where the oracle is not just a "nice to have" — it's the core mechanism that drives the entire insurance protocol.
