MoneroP2PMoneroP2P Wallet: a Monero browser extension for Chrome and Firefox
In short: on November 5, 2026 we launched MoneroP2P Wallet 0.2.0, a non-custodial Monero wallet for your browser that runs on Chrome, Brave, Edge, Opera and Firefox. One 25-word seed holds your XMR and an Arbitrum One account with USDT and ETH, so you can swap USDT for Monero on MoneroP2P without MetaMask and without copying addresses around. It is free and open source.
Why a Monero wallet in the browser
Until now, using Monero meant a desktop app (Feather or the official wallet) or a phone app (Cake Wallet). Websites talk to MetaMask, but MetaMask does not support Monero. Swapping USDT for XMR on a website meant two wallets and copying addresses between them.
MoneroP2P Wallet puts both in one extension: your Monero and your Arbitrum account live in the same place, and MoneroP2P’s sites use it directly.
What it does
- Full Monero wallet: create or restore with the standard 25-word seed, balance, history with confirmations, and sends that show the exact fee before broadcasting.
- A fresh subaddress for every payment, with a QR code, so nobody can link your payments.
- USDT and ETH on Arbitrum One: the same seed creates your Arbitrum account, with balance, receive with QR and send with an estimated network fee.
- Explore: one click opens the USDT to XMR exchange or P2P Fiat, where you buy XMR with your local currency.
- Site connection: on monerop2p.app and fiat.monerop2p.app the wallet fills in your Monero address and signs the swap deposit. Every step asks for your approval in an extension window.
- Your own node: swap MoneroP2P’s node for yours in Settings.
How it protects your funds
| Layer | What it does |
|---|---|
| Non-custodial | The seed is created and stays on your device. No accounts, key servers or analytics. |
| Encrypted vault | Argon2id (64 MiB) turns your password into a key and XChaCha20-Poly1305 encrypts the wallet. |
| Auto-lock | After 15 idle minutes (configurable) and when the browser closes. |
| No remote code | All code ships inside the extension, with a strict Content Security Policy. |
| Two sites only | The extension only talks to monerop2p.app and fiat.monerop2p.app, and only with your approval. |
| Decoded approvals | Before signing you see in plain words what the transaction does: transfer, spending approval or swap deposit. |
| Address poisoning check | Warns you if you paste an address that looks like one you used but isn’t. |
| Verifiable | Open source (AGPL-3.0) and a reproducible package with its SHA-256. |
Keep your seed on paper. It is the only way to recover your funds if you lose or replace your device.
How it compares with other Monero wallets
| MoneroP2P Wallet | Feather | Cake Wallet | Official GUI | |

| USDT on Arbitrum | Yes | No | Other networks | No |

For large long-term savings, a desktop or hardware wallet is still the best choice. MoneroP2P Wallet is built for buying, receiving and moving XMR day to day from your browser.
Fees
- Extension: free.
- Mainnet XMR sends: Monero network fee plus a 0.25 % MoneroP2P fee, shown on its own line before you confirm. Amounts whose fee would be under 0.00001 XMR don’t pay it.
- No MoneroP2P fee: receiving, sending to your own addresses, stagenet and Arbitrum sends (you only pay the network there).
How to get started
- Go to monerop2p.app/en/wallet and pick your browser’s store.
- Create the wallet with a long, unique password.
- Write the 25-word seed on paper. It is the only way to recover your funds.
