Gas Optimization

Attestations are queued when Polygon gas exceeds 50 Gwei. A background worker checks every 5 minutes and auto-mints when gas is optimal.

DAP attestations provide proof of data delivery only. They do not constitute compliance certification or regulatory approval. Users are responsible for their own compliance decisions.
