Wormhole V1 was initially built by Certus One and other core contributors in October 2020 as a bi-directional token bridge between Ethereum and Solana. The developers found an increase in demand for more interoperability and supported chains from the users’ feedback. As a result, Wormhole network, a generic message-passing protocol, was launched in August 2021. Unlike V1, the new protocol can connect to more chains and has increased functionality, enabling arbitrary data to be sent cross-chain, including tokens, NFTs, oracle data, governance decisions, and more!
Moving forward, Wormhole V1 will be decommissioned by March 31st, ensuring users have sufficient time to migrate their assets.
For the following V1 tokens on Solana, there is a migration platform allowing users to swap for 1–1 for Wormhole V2 tokens. Check out our guide here.
Tokens available for migration include:
If you have V1 tokens that are not listed above, you must use the V1 token bridge to send the tokens back to Ethereum.
Attention: Do not use the Portal bridge for V1 tokens, as this would result in double wrapped and thus useless tokens!
