NOTE: Bridging of HOT on L2 blockchains like Base or Arbitrum is not supported. Only bridging of HOT on the Ethereum blockchain is supported.
Multi-signature arrangement: We use Gnosis Safe multi-sig wallets to manage the Bridge Contract and also to authorize release of locked HOT Tokens. Signers are independent parties; no single party, including Net Zero, can release locked HOT Tokens alone.
Verify every address on a block explorer before transacting. Addresses are never sent to you by message, they are automatically linked from inside the Unyt HoloFuel app.
Swap Window
The Token Swap from Mirrored HOT to HoloFuel opens on 1 November 2026 and remains open for at least six months from that date. We will publish a 60 days notice of any intent to close the bridge or alter the exchange ratio. Bridging out of Mirrored HOT to HOT Tokens isn’t limited by the Swap Window.
System rules
Ratio. One Mirrored HOT to one HoloFuel, both directions, no fee, no spread.
Eligibility to swap from HoloFuel to (Mirrored) HOT. Only HoloFuel earned through providing network utility within the System where payment is received via one of the authorized harvesting agreements.
Credit Limits.
- General user accounts: None
- Service-provider / Host accounts: None at launch. May later be increased to use an earnings-based algorithm.
- Infrastructure Provider: ~177 billion units (equivalent to the HOT supply), divided evenly between two infrastructure providers. Holo as provider of HOT and hosting infrastructure. Net Zero as the provider/operator of HoloFuel and the transactional infrastructure.
