How to lock BTC

Locking BTC gives you a veBTC NFT, which grants voting power, protocol fees, and governance rights. See the veBTC Overview for details on what you earn.

Prerequisites

Before locking BTC, ensure you have:

  • BTC deposited on Mezo
  • A connected wallet
  • Sufficient BTC for gas fees

See the Getting Started section for guidance.

  1. Open the Mezo app
  2. Click Lock in the left sidebar (under “Earn”)
  3. You’ll see your eligible assets

Initiate Lock

Find the BTC asset card showing your available balance and click Lock. A lock configuration modal appears where you’ll configure your position.

Amount: Enter the amount of BTC you want to lock. You can lock any amount up to your available balance.

Duration: Select your lock duration from 1 to 28 days. Longer locks maintain higher voting power for longer periods. The interface shows your estimated initial veBTC voting power, which represents your weight at the start of the lock.

Note: Lock durations are aligned to epoch boundaries and rounded down to the nearest full week. A max lock created mid-epoch will result in an effective duration of 21–28 days. See Epochs for details.

Review your lock details:

  • BTC amount
  • Lock duration
  • Initial veBTC weight
  • Lock expiration date

Click Confirm Lock, approve the transaction in your wallet, and wait for blockchain confirmation.
