The short version

What changed, and why it matters

This commit adds support for resolving human-readable payment names (like DNS-based addresses) inside Sparrow Wallet's 'send to many' dialog. It also refactors how the OK button and CSV loading work, and adds a cache so resolved addresses don't need to be looked up repeatedly. There is no clear security bug in the diff, but the change involves network lookups and address resolution, so it deserves normal review care.

Recommended action

Treat as a normal feature commit. Reviewers should verify that DnsPaymentResolver validates DNSSEC/TLS where applicable, that resolved addresses are not silently substituted, that the cache cannot be poisoned by colliding keys, and that the async task handles cancellation and errors without leaking partial payment lists. No immediate security patch appears required from this diff alone.

Security signals we found

01

Network resolution of user-supplied identifiers (DNS payment HRNs) now occurs in a bulk-payment dialog.

02

Resolution results are cached; cache keys are derived from resolved Bitcoin addresses or silent-payment addresses.

03

User is prompted to connect to the configured server when offline and an HRN needs resolution.

04

CSV parsing accepts HRN strings and defers address validation until resolution time.

05

No input sanitization beyond existing DnsPayment.getHrn() helper is visible in this diff.
