ScreeningCoreField

Fields needing no vendor response, so they work in both phases, and the only fields a pre-screen rule may use. tx.amountUsd and tx.asset are present only where the request establishes them; neither is available on the signing path. address compares case-sensitively, since base58 chains are case-significant. An absent field compares unknown, so the rule sits out.

Available options: tx.amountUsd, tx.asset, chain, address

Example:

{ "title": "Example" }
