AirGap Implementation
In AirGap's implementation, the low threshold must be lower than the medium threshold, and the medium threshold must be lower than the high threshold. Additionally, the total combined weight of all signers must exceed the high threshold. This design enforces proper multisig hierarchy, preventing misconfigurations that could allow low-weight signers to authorize high-level operations.

Since this is a multisig account, broadcasting the transaction without meeting the required threshold will fail. Therefore the "comfirmed" button is disabled by default. Toggle the "Display Details" button to copy the XDR and complete the signing process.
