# Dogecoin wallet support for Doge Commerce (research 2026-10-27)

Doge Commerce needs: (1) **signmessage** with a P2PKH `D…` address to sign listings/receipts/cancels, (2) optional **account xpub/dgub** for per-order addresses. Never paste private keys or seeds into the app.

| Wallet | signmessage | xpub export | Role | Sources |
|--------|-------------|-------------|------|---------|
| **Dogecoin Core** (desktop) | Yes — GUI File → Sign message…; RPC `signmessage` | Not a simple BIP44 account export in the GUI (use receive address; for xpub prefer HW) | **Best seller desktop** for signing | Core `rpcwallet.cpp` signmessage; GUI File→Sign message (dogeducation guide; Core Qt translations) |
| **Trezor Suite** | Yes — Dogecoin lists `sign-verify`; Suite Sign & Verify | Yes — Account → Details → Show public key | **Best HW** all-round | trezor-suite `networksConfig.ts` doge features; trezor.io Sign & Verify guide; XPUB learn article |
| **Ledger (Ledger Wallet)** | Not clearly documented for DOGE in support article — do not give exact sign steps | Yes — account Edit → Advanced → xPub; DOGE app Settings → Public key export approval | Good for xpub + receive; signing: verify in your firmware/app before relying | support.ledger.com Dogecoin article (updated 2026-05-13) |
| **MultiDoge** | Yes — Tools → Sign Message | Not researched here | Desktop alternative for signing | multidoge.org help Sign and Verify Message |
| **MyDoge** (mobile) | No public docs for arbitrary message signing | Community reports no xpub; help covers receive/send only | **Buyer/pay phone** — receive & send DOGE; not for seller signing | MyDoge help FAQ; reddit r/dogecoin xpub thread |
| **Sparrow** | Message signing exists for Bitcoin wallets | N/A | **Not recommended for DOGE** — Bitcoin-focused | Sparrow MessageSignDialog (Bitcoin script types) |
