Trade Bitcoin directly with other people through the Mostro peer-to-peer protocol, using Lightning and Nostr.
MostroEuropa is an independent European community operating a Mostro coordinator. We are not the P2P protocol itself: Mostro is the protocol, and our coordinator is one access point to it.
Mostro is the open-source peer-to-peer Bitcoin exchange protocol. It uses Nostr for communication and Lightning hold invoices to coordinate trades without a traditional custodial exchange.
Official Mostro website ↗MostroEuropa is an independent European community for users of Mostro. Our goal is to help users discover the protocol, access a European coordinator and build reputation through real P2P use.
Compatible Mostro clients can connect to our coordinator using its Nostr public key and the relays published below.
Open the guide →Choose the client you want to use. Every client needs the identity of the MostroEuropa coordinator. Terminal clients also need the Nostr relays used by our coordinator.
Follow the real Mostro Mobile interface shown below. The screenshots are from the current app and show the exact path used to add a custom coordinator.
Open the side menu and tap Settings.
On the Settings page, scroll down. The Mostro section is further down the page.
Find the Mostro section and tap the current node card marked Tap to change.
In Select Mostro Node, scroll to Custom Nodes and tap Add Custom Node.
Paste the MostroEuropa npub into Public Key. The app accepts hex or npub. Name is optional. Then tap Add Custom Node.
Paste this exact public key into the Public Key field:
After adding it, the coordinator appears under Custom Nodes. The screenshots currently show its existing public metadata name, “Shadowbip Mostro”.
Back up the recovery phrase generated by the client. If you configure a default Lightning Address, use an address you control and verify it before relying on it for a trade.
MostriX stores its configuration in ~/.mostrix/settings.toml. The official MostriX documentation exposes the coordinator public key, relays and currency filters in this file.
~/.mostrix/settings.toml.mostro_pubkey to the MostroEuropa npub.currencies filter to the fiat markets you want to see.
mostro-cli requires MOSTRO_PUBKEY and RELAYS. The CLI accepts the coordinator npub or hex public key.

On first use, mostro-cli creates your local user identity and a 12-word mnemonic. Back it up before trading. The CLI does not automatically load a .env file; export variables or source them from a shell file yourself.

Mostro uses Lightning for the Bitcoin side of the trade. Use a wallet you control and understand.
A commonly used self-custodial Lightning wallet suitable for receiving and paying Lightning invoices.
Official website ↗A self-custodial Lightning wallet and node interface widely used by experienced Lightning users.
Official website ↗The buyer provides a Lightning invoice where the sats will be received. Clients that support a configured Lightning Address may simplify this step.
The seller pays Mostro's Lightning hold invoice. A hold invoice can remain pending or in-flight during the trade; follow the Mostro client workflow until the trade is settled or released.
Mostro reduces reliance on traditional custodial exchanges, but peer-to-peer trading still requires you to understand Lightning, the payment method and the trade state shown by your client.
Use the coordinator npub, not a display name alone.
Do not move the settlement process outside the protocol while a trade is active.
If your client gives you a mnemonic or recovery phrase, store it safely before you depend on the client for active trades.
We are building a European community around the Mostro protocol. The coordinator is the infrastructure we operate; the community is the people who use it, help each other and build reputation over time.
