Will the relaunch impact $ZEN holders and the $ZEN tokenomics?
$ZEN’s fixed 21 million supply will remain unchanged. While the details of an updated tokenomics are still being finalized, key considerations include:
How will this move affect $ZEN liquidity?
Integrating into Base brings $ZEN closer to a highly liquid ecosystem, making it easier for users and developers to access and trade. Base's strong ties to Coinbase improve visibility and increase the likelihood of deeper exchange integrations and institutional support.
Will this shift to Base impact the Grayscale Horizen Trust (HZEN)?
No. Grayscale already uses Coinbase Custody for asset storage, aligning well with Horizen’s move to Base - a Coinbase-backed ecosystem. This strategic shift further strengthens ZEN’s institutional positioning and enhances its visibility within the broader Coinbase and Grayscale networks.
Will Horizen still support EVM and Solidity smart contracts?
Yes! Moving to Base ensures full EVM compatibility, making it easier for existing developers to deploy on Horizen without needing to learn a new framework.
