Some API versions return the transaction address (and each input address) as a nested object instead of a plain string. That object was copied straight into Transaction.address, and the next address parse threw "Invalid address prefix.", which surfaced on the host page as an uncaught promise rejection whenever the widget re-checked the transaction history (for instance on tab focus). Normalize the address as soon as it arrives, fall back to the queried address when the API sends none, and stop a failing transaction handler from rejecting unhandled.

A failing chronik connection rejected inside an unawaited async effect, which both showed up as an uncaught error on the host page and skipped the SideShift socket setup entirely. Log the failure instead and carry on with the altpayment connection, which does not depend on chronik.

With a preselected coin the widget went straight to the "Loading SideShift..." screen and waited for a shift, but the automatic rate/quote requests were skipped whenever the amount was editable — which is also the case for buttons with no amount at all. The result was a spinner that never resolved. Editable buttons now request the rate as soon as the coin is preselected and show the amount form (prefilled with the converted amount, labelled with the deposit coin) instead of the automatic loading screen. An unrecognized ticker falls back to the regular coin selector, and every SideShift step gives up with an error message instead of spinning forever when the service never answers.

Covers the case where the user types the BTC amount instead of paying a fixed one, which previously never left the loading screen. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01VBtWogj1C1LvKsLY5NTtMv
A mistyped or non-eCash/BCH address made getCurrencyTypeFromAddress throw while rendering, so the whole button vanished from the page with an "Invalid currency" error in the console — even though both PayButton and Widget already have an "Invalid Recipient" message for exactly this case. Components now fall back to a default ticker when the address cannot be parsed and let that message render.

Typing an amount fed the converted settle amount back into the button amount,
which for fiat buttons is denominated in the fiat currency: the value grew on
every round trip, and the quote — built from that derived value rather than from
the input — asked SideShift for a wildly larger deposit ("Amount too high.
Maximum deposit amount: …") on a perfectly valid amount.
The quote now uses the typed amount directly, and the widget converts the settle
amount back into the button currency before updating it.
Also stop the coin/network pickers from flashing by before the rate arrives when
the coin is preselected, and drop the back button that pointed at a coin step
that does not exist in that case.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Reject non-finite typed deposit amounts.
Line 318 accepts Infinity because Number.isNaN(+pairAmount) is false. A value such as 1e309 can then produce an invalid depositAmount. Require a finite value before conversion and quote creation.
Proposed fix
- Number.isNaN(+pairAmount) ||
+ !Number.isFinite(+pairAmount) ||📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Description
Fixes issue with QR-code being cut on mobile screens when paying with BTC for a ecash button.
Even after scrolling down, content would not all be visible.
Test plan
Try the new button Pay with BTC (editable) in http://localhost:10001 after running
yarn watchusing a mobile screen, it should not even present a scrollable interface anymore but one in which everything is visible at once.Summary by CodeRabbit
