Getting started

From your first sign-in to your first commitment.

Create or return to your account

Choose Get started, then create an account with a Mera passkey. Your device may use Face ID, Touch ID, its screen lock, or a compatible password manager. To return, choose Sign in with your passkey and use the same credential. Creating another passkey creates another account.

Bondline derives a signing account during the passkey ceremony and ends the signing session afterward. There is no seed phrase screen or custodial account recovery service. A compatible browser wallet is an alternative, not a requirement.

Check your account before funding it

Open the account menu to copy your complete address and see the network and available MON. Send funds only on the network shown. The current v2 deployment is on Monad testnet; test MON has no cash value. A mainnet transfer will not fund an account’s testnet balance.

Your stake and transaction fee both come from your available balance. Leave room for fees; sending the entire balance is not a useful starting point.

Join your people

Create a Circle by choosing a name, adding at least one friend’s account address, and choosing the evidence approval threshold. Initial members are registered at creation. To join an existing Circle later, ask a member to invite your address and share the Circle link. Open Members and accept the invitation.

Circle chat is accessible only to members with a valid signed-in app session. On-chain commitments and outcomes are public; chat messages are not published on-chain.

Make your first commitment

Open your Circle and choose Make a commitment. Describe an achievable goal, choose a deadline, enter a stake, and select a verification method. The next screen shows the exact deadline, amount, and completion rule. Confirm only if those details are right.

A commitment appears after its transaction confirms. For Circle-reviewed goals, submit evidence before the deadline. Encouragement from friends is separate from approval of that evidence.

If something does not work

  • A missing balance usually means the wrong network or an unfunded address. Check the account menu.
  • An expired private session can be renewed with Continue to chat. Renewing a session does not cost gas.
  • Cancelling the account confirmation leaves the proposed action unsubmitted.
  • For a pending action, inspect the explorer link before trying again. A failed transaction can still cost a fee.
  • Do not share a private key, passkey recovery information, or provider secret with support.
