veBTC

veBTC (voting escrow BTC) is an NFT that represents your locked Bitcoin position on Mezo Network. When you lock BTC on Mezo Earn, you receive a veBTC NFT that tracks your lock and grants you voting power in the ecosystem.

veBTC is the foundation of participation in Mezo’s governance and rewards system. Each veBTC NFT contains:

  • Locked amount - How much BTC you’ve locked
  • Lock duration - When your lock expires (or if it’s permanent)
  • Voting power - Your influence in the system, based on amount and duration
  • Boost multiplier - Enhancement from veMEZO votes (can reach up to 5x)
  • Associated gauge - The smart contract that receives votes on your behalf

You obtain veBTC by locking BTC on Mezo Earn:

  1. Visit Mezo Earn
  2. Navigate to the Lock section
  3. Choose your lock amount (in BTC)
  4. Select your lock duration (1-28 days)
  5. Confirm the transaction
  6. Receive your veBTC NFT
DurationUse Case
1-7 daysShort-term participation, test the waters
7-14 daysMedium-term commitment
14-28 daysMaximum initial voting power
PermanentOpt-in for sustained maximum power

Your veBTC voting power is determined by:

Voting Power = Locked Amount × (Time Remaining / Max Lock Duration)

This means your voting power decays linearly as you approach your unlock date.

If you lock 1 BTC for 28 days:

  • Day 0: 1 veBTC voting power
  • Day 14: 0.5 veBTC voting power
  • Day 21: 0.25 veBTC voting power
  • Day 28: 0 veBTC (unlock available)

To prevent decay:

  • Extend your lock - Add more time to reset decay
  • Enable permanent lock - Maintain maximum voting power indefinitely

One of the most powerful features of veBTC is the ability to receive a boost multiplier from veMEZO votes. This is where Matchbox comes in.

  1. Your veBTC has a baseline voting power (unboosted)
  2. veMEZO holders can vote on your gauge
  3. These votes increase your boost multiplier
  4. A higher boost means more rewards from Mezo Earn
BoostMeaning
1.0xNo boost - only your base veBTC power
1.5x50% increase in effective voting power
2.5x150% increase in effective voting power
5.0xMaximum boost - 400% increase

The maximum boost of 5x requires significant veMEZO support.

Every veBTC position is associated with a gauge - a smart contract address that:

  • Receives votes from veMEZO holders
  • Tracks your boost multiplier
  • Can hold incentives to attract voters

On Matchbox, you can customize your gauge with:

  • Display name and description
  • Profile picture
  • Social links
  • Incentive offerings

See Understanding Gauges for more details.

Control over mats (Mezo’s incentive token) emissions across the ecosystem. Your votes direct where incentives flow.

Earn a share of chain activity and bridging fees proportional to your boosted voting weight.

Shape Mezo’s economic direction by participating in governance decisions.

On Matchbox, you can:

  • Create a gauge profile to attract voters
  • Offer incentives to boost your position
  • Monitor your gauge’s performance

Once locked, your BTC cannot be withdrawn until the lock expires (unless you have a permanent lock with specific unlock conditions).

Lock durations align to epoch boundaries (Thursday 00:00 UTC). This means your lock will round down to the nearest full week.

To earn active rewards (beyond passive bridging fees), you must vote each epoch. Non-voting in an epoch forfeits active earnings for that period.

On Matchbox, veBTC holders can:

  1. View their positions - See all veBTC NFTs in the Dashboard
  2. Manage gauge profiles - Customize how your gauge appears to voters
  3. Add incentives - Offer bribes to attract veMEZO votes
  4. Monitor performance - Track boost multiplier, votes received, and APY
  5. Transfer profiles - Move gauge settings between veBTC NFTs
