# Wallets

## Supported wallets

**Phantom** (recommended), **Backpack**, and **Solflare** are supported directly, plus any other installed wallet through the "More wallets" option in the connect modal — Bextree uses the standard Solana wallet adapter, so anything compatible with it works.

## How wallet auth works

Bextree has no passwords and no login. Every action that touches wallet-owned state — placing a bid, listing an asset, updating your profile — works like this:

1. Bextree issues your wallet a **one-time nonce** (a random challenge tied to the specific action).
2. Your wallet signs a message containing it. The signing happens entirely inside your wallet, on your device.
3. The server verifies the signature and **consumes the nonce** — it can never be used again, and it expires almost immediately if unused.

This means a captured signature is useless for replay, and Bextree never sees — and never could ask for — your private key or seed phrase.

## What Bextree will never ask you to do

* Share your seed phrase or private key, anywhere, ever.
* Sign a transaction to "verify" or "sync" your wallet outside the flows described in these docs.
* Send funds to an address to "unlock" a feature.

If something claiming to be Bextree asks for any of these, it's a scam — see [Contact](/company/contact.md) to report it.
