Description

Phantom has deprecated several integrations since our adapter was written, and the first of them broke pairing outright:

  • Bitcoin — Phantom deprecated the window.phantom.bitcoin provider (changelog: notice week of April 20, 2026, removed week of June 15, 2026). PhantomAdapter.pairDevice required that provider, so every connect attempt threw Phantom provider not found and opened the install page, even with the extension installed. Bitcoin stays as an in-wallet asset in Phantom; only the dApp provider is gone.
  • Sui — deprecated September 24, 2026 (announced August 24). window.phantom.sui is no longer injected, and _supportsSui = true made Sui account discovery throw error getting address from wallet for every Phantom user.
  • Monad — deprecated September 1, 2026.

This PR:

  • Drops Bitcoin and Sui from hdwallet-phantom entirely: the bitcoin and sui modules, their provider types, wallet methods, BTCWallet / SuiWallet implementations, and the @shapeshiftoss/bitcoinjs-lib, base64-js, bitcoinjs-message deps. PhantomHDWallet is now new PhantomHDWallet(evmProvider, solanaProvider) and implements ETH + Solana.
  • Sets _supportsMonad = false.
  • Enables _supportsBSC, which Phantom lists as an active network alongside the chains we already enable.
  • Removes the Phantom-specific BTC carve-outs in useWalletSupportsChain, the portfolio utils, deriveUtxoAccountIdsAndMetadata, and the hdwallet Bitcoin integration suite, which are dead now that supportsBTC is false for Phantom.

Risk

High Risk PRs Require 2 approvals

What protocols, transaction types, wallets or contract interactions might be affected by this PR?

Medium. Phantom wallet only.

  • Phantom users regain the ability to connect at all.
  • Existing Phantom users with persisted BTC or Sui accounts lose them from the portfolio on next load (those accounts can no longer be read or signed for through Phantom regardless).
  • BSC becomes available for Phantom; chain switching to BSC goes through the same wallet_switchEthereumChain path as Base/Polygon.
  • No changes to other wallets. The integration-suite edits only remove Phantom skips from tests that Phantom no longer reaches.

Testing

Engineering

  • pnpm exec vitest run packages/hdwallet-phantom (9 tests).
  • Phantom's content script only injects its EVM provider on https: origins or a hostname of exactly localhost / 127.0.0.1, so under portless (http://web.localhost:1355) Phantom will not appear in the wallet list at all. Run pnpm run dev:web:localhost to test it locally.
  • With the Phantom extension (26.31.0 or 26.32.0):
    1. Connect Wallet → Installed → Phantom → Pair. Should pair instead of redirecting to phantom.app.
    2. Portfolio should discover EVM (Ethereum, Base, Polygon, BNB Chain, HyperEVM, Robinhood) and Solana accounts, with no Bitcoin or Sui accounts and no Sui getAddress error in the console.
    3. Switch to BSC in a trade or send flow and confirm Phantom prompts for the chain switch.

Operations

  • 🏁 My feature is behind a flag and doesn't require operations testing (yet)

With the Phantom browser extension installed and unlocked:

  1. Open Connect Wallet, pick Phantom, click Pair. It should connect; previously it opened phantom.app in a new tab and showed an error.
  2. Check the portfolio: Ethereum, Base, Polygon, BNB Chain and Solana balances should load. Bitcoin and Sui should not be listed for the Phantom wallet.
  3. Send or trade on BNB Chain with Phantom and confirm the signing prompt appears in the extension.

Phantom no longer injects window.phantom.bitcoin (deprecated June 2026),
so pairing threw "Phantom provider not found" and redirected to the
install page for every user (SS-5770). Phantom has since also deprecated
Sui (Sept 24, 2026) and Monad (Sept 1, 2026).

- PhantomHDWallet now implements ETH and Solana only; the bitcoin and
  sui modules, providers, wallet methods and deps are removed
- _supportsMonad is false
- web and integration tests drop the Phantom-specific BTC carve-outs,
  which are dead now that supportsBTC is false for Phantom

🟠 Major · Remove the leftover describe('Bitcoin') block. · phantom.ts:156-233

packages/hdwallet-integration/src/wallets/phantom.ts:156-233
🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Remove the leftover describe('Bitcoin') block.

The file still has the Bitcoin suite at lines 156-233. It calls wallet.btcGetAccountPaths, and wallet has the type phantom.PhantomHDWallet. This PR removes that method from PhantomHDWallet, so the type check fails.

At runtime, describePath with coin: 'Bitcoin' now reaches the default branch. That branch throws 'Unsupported path', so the three describe-path tests also fail. Those tests do not have the if (!wallet) return guard.

The change summary says these tests were removed, but they are still in the final file. Delete the whole block.

Proposed fix
-  describe('Bitcoin', () => {
-    it('uses correct bip44 paths', () => {
-      ...
-    })
-    ...
-  })
 }
