For Exchanges and Brokers this guide contains all the information needed for the migration of BZRX token to OOKI token.


Following a bZx DAO vote, the community has adopted the proposal to migrate BZRX to a new token contract. Exchanges can use the guide below to prepare for the migration.

Migration Instructions

The tokens can be upgraded at any time, but we recommend taking action as soon as possible by completing the following steps:

  1. Upgrade the old tokens held in exchange wallets. Using the Ethereum address that holds the tokens to be upgraded, you can either:
    1. Use the Token Migration Tool
      1. Approve BZRX for spending by the conversion contract:
      2. Call convert on the contract. The migration contract is live.
      3. This is the interface for conversion contract:
    2. Use the Converter Page
      1. The migration contract is live.
  2. Rename the old BZRX token to OOKI in user interfaces and APIs and update branding assets.
  3. Support deposits and withdrawals for both old and new token so that users don’t accidentally lose their tokens.
  4. Switch all trading pairs to the new token.


Please start using the updated name, symbol, icon, and supply metrics for both the old and new token. Please find all the relevant information below:

OOKI Description

Ooki is a protocol for margin trading, borrowing, lending and staking. Ooki Protocol allows anyone to build applications that enable lenders, borrowers, and traders to interact with the most flexible decentralized finance protocol on multiple blockchains. Ooki is a fully decentralized, community-run project, governed by the community vote for all major changes to the protocol.

OOKI Token

The OOKI token is a governance token that allows the Ooki community to govern the protocol through staking OOKI token and voting in the Ooki DAO. The Ooki ecosystem is designed to emphasize community control over the protocol through governance, fee sharing, and voting.
