• PR is titled with conventional commit style naming: type(scope): message
• Breaking change marker not needed: the constant is not exported from any published entry point

Summary

Remove the unused AXELAR_SCAN_URL constant from checkout/widgets-lib. Linear: BLOC-588 (parent BLOC-558, Axelar dead-code cleanup for the zkEVM → OP Stack migration).

Detail and impact of the change

Removed

• AXELAR_SCAN_URL (per-environment Axelarscan GMP base URLs) and its doc comment in packages/checkout/widgets-lib/src/lib/constants.ts. No file in the repo imports it. The add-tokens and purchase widgets that still link to Axelarscan build the URL inline from the Squid transaction hash and are untouched.

Anything else worth calling out?

Behaviour change: none. Widgets-lib is internal to the widgets bundle, so nothing consumer-facing changes. Verification is the repo-wide grep (only the definition matched) plus CI lint and typecheck for checkout-widgets; a local tsc in a fresh worktree needs the workspace packages built first, so the CI run is the gate here.

Verification that nothing consumes AXELAR_SCAN_URL

Checked on main (3aaa44d64):

1. In-repo. The only match for AXELAR_SCAN_URL in any file type is the definition. src/lib/index.ts re-exports * from './constants' and 24 files import that barrel, but none names this constant; there is no namespace import (import * as) of lib/constants that could reach it dynamically.

2. History. The last consumer was components/Transactions/TransactionList.tsx (setLink(AXELAR_SCAN_URL[checkout.config.environment])), removed in fix(checkout-widgets): Fetch pending withdrawals from the bridge contract #2680 (cce02d68c, 2025-08-19). Nothing has referenced it since.

3. Published package. In @imtbl/checkout-widgets@2.24.9 the constant survives only as an orphan declaration in dist/types/lib/constants.d.ts. The package entry (dist/types/index.d.ts → ./factory) does not re-export lib, and the exports map exposes only the root, so no consumer can import it. The runtime bundle does not contain the constant's URLs at all (testnet.axelarscan.io/gmp/ is absent); the only Axelarscan string in dist/browser is the inline template the add-tokens and purchase widgets build from the Squid tx hash, which this PR does not touch. @imtbl/sdk@2.24.9 likewise has no trace of it.

4. Org-wide GitHub code search. Outside this repo the name appears only in immutable/prodsec-malicious-hub-app, which vendors a 2023-era copy of widgets-lib (including the old TransactionList.tsx); it is a snapshot for security research, not a package consumer.
