autoBTCv2+ Migration Guide

Autofarm has undergone Venus v2 Vault migration on April 9, 2021. According to Autofarm, the vault migration aims to provide enhanced security and optimized earnings for Autofarm users.

Autofarm migration details can be found here:

To cope with the Autofarm migration, autoBTC+ users are required to migrate staked autoBTC+ assets to the new autoBTCv2+ vault in order to continue earning rebased interests and AC rewards.

To differentiate between new and old autoBTC+ vaults, please take note of the following naming conventions:

Migrated vault = autoBTC+

New vault = autoBTCv2+

Migrating to autoBTCv2+

Step 1: Withdraw staked autoBTC+ from autoBTC+ vault. Remember to claim any unclaimed AC rewards.

Step 2: Redeem autoBTC+ into BTCB

Step 3: Mint autoBTCv2+ with BTCB

Step 4: Deposit the newly minted autoBTCv2+ into autoBTCv2+ liquidity pool

Supplemental Information

Autofarm has also introduced a new fee structure for their Venus v2 vaults:

At the launch of Venus v2 vaults

  • Withdrawal fees: 0.1%
  • Entrance fees: 0%

3 days after the launch of Venus v2 vaults

  • Withdrawal fees: 0.1%
  • Entrance fees: 0.1%

Once v2 vaults go live, old vaults will no longer receive earnings and users will only be able to harvest and withdraw their remaining assets. The deposit function will also be disabled to prevent users from mistakenly staking assets into these retired vaults.
