BM.XYZ is fully non-custodial. You connect a wallet you own and control — BM.XYZ never holds, accesses, or stores your private keys. Your assets stay in your wallet until you place a trade on the order book.

Connect flow

1

Open the connect prompt

Click Connect Wallet in the top navigation bar or in the trade panel on any market page.
2

Select your wallet provider

Choose your wallet from the list of supported providers in the connection modal.
3

Approve the connection request

Your wallet will display a connection request. Review the site origin (bm.xyz) and approve it. No funds are moved at this step.
4

Confirm your address

Once connected, your wallet address appears in the top bar. You are now connected but not yet authorized to trade — complete the Enable Trading flow next.

​
Enable Trading

Connecting your wallet alone does not authorize order submission. You must complete the Enable Trading flow once per session (or per deployment on testnet).
1

Claim testnet tokens

Click Enable Trading and then Claim on the faucet step. This credits your account with test USDC and BMX. If you have already claimed, this step shows a completed state and you can proceed immediately.
2

Sign to establish a trading session

Sign the gas-free message in your wallet to create a local trading key. This signature authorizes the exchange to submit orders on your behalf without requiring a separate on-chain transaction for every trade.If you want to stay signed in across browser sessions, opt in to Stay Connected when prompted.

Security tips

  • Never share your seed phrase or private key with anyone, including anyone claiming to be BM.XYZ support.
  • Verify the URL is bm.xyz before approving any signature or transaction in your wallet.
  • Disconnect your wallet when you are finished, especially on a shared or public device.
