Mainnet isn’t live yet. Use Soak to try ProofBridge today.
ProofBridge works with one wallet per chain:
  • EVM (Sepolia): MetaMask, Rainbow and other browser wallets, or WalletConnect
  • Stellar (Testnet): xBull, Freighter, Lobstr, Hana, or WalletConnect
Click Connect Wallet to open the wallet hub. It lists each network and whether you’re connected and signed in there.

The wallet hub: connect and sign in per network

​
On a phone

Freighter, Lobstr and Hana’s browser versions are desktop extensions. On a phone, connect with xBull or through WalletConnect (for example, the Lobstr or Freighter mobile app).

​
Which wallets do you need?

The wallet of the chain you deposit from is required. Connecting both is recommended:
  • as a Bridger, you deposit on the order chain and receive on the other chain
  • as a Maker, your liquidity lives on the ad chain and you receive on the order chain

​
Sign in

Connecting asks for a one-time sign-in signature: a challenge, with no transaction and no gas. EVM wallets sign a Sign-In with Ethereum message; Stellar wallets sign a SEP-10 challenge. Connecting your second wallet links it to the same account, so the app shows all your trades in one place. The hub shows Link wallet required until you do. You stay signed in while you use the app. After two weeks without use, or 30 days in all, you sign in again.
Each trading wallet also needs a one-time settlement key registration before it can complete trades. The app prompts you when it’s needed, or you can do it up front on the BLS Keys page.
