From the ICO until now, one of the questions we’ve been continuously asked is “when HoloFuel?”
We’re not quite there yet, but the technical infrastructure is moving into a critical test phase to ensure we have the necessary speed, stability, and security to support the technical migration from a pre-sale to a utility token.
What’s Happening
Starting April 15th, 250 beta testers will use mock HOT tokens on the Sepolia Ethereum testnet to help us better identify any constraints and failure points that will adversely impact a large-scale technical migration.
This is the first live community test of blockchain bridging we’re conducting with Unyt outside of our core team, and it will operate in a controlled environment in order to ensure there’s no risk to participants’ real tokens.
As with all user testing, the process will follow a predetermined script, and will take roughly 30 minutes to complete.
How it Works
This is a test of a HOT-to-Wrapped-HOT-to-HoloFuel transition flow.
- To start, a tester connects a crypto wallet, and obtains test ETH and mock HOT through a pair of free token faucets. From within the Unyt app, they will start a Transfer-In from their wallets, then will lock their mock HOT tokens on the Sepolia testnet by sending them to a specific locking smart contract.
- A bridge agent detects the lock and makes an equivalent amount of wrapped HOT available inside the Unyt app. This wrapped HOT is not the original ERC-20 token. It is a representation of it inside the Unyt app, held in place by a cryptographic record of the lock on-chain.
- Testers can also run the process in reverse. The Transfer-Out step sends wrapped HOT to the bridge agreement, and then a bridge agent generates a cryptographic coupon redeemable to unlock HOT tokens on the Sepolia blockchain and send them to the designated wallet.
- Within the Unyt app, we’ve set up a simple mechanism for converting mirrored HOT 1:1 to HoloFuel, the mutual-credit currency of the Holo hosting network.
Architecture Note: The rules that govern how HOT gets bridged are configured as a smart agreement inside Unyt. Smart agreements are peer-validated economic rules that can be reconfigured without rebuilding the application. The HOT bridging agreement is one of them.
Why This Matters
The HOT token was issued in 2018 as a pre-sale claim on future HoloFuel hosting capacity. HOT was always a service redemption mechanism. The technical migration is how that redemption becomes real.
Building the bridge between Ethereum and Holo's economic infrastructure is not a simple problem. HOT lives on a public blockchain. Holo’s redemption credits will operate in a Unyt app context that is agent-centric and peer-validated, but is not a blockchain and has no global ledger. The approach that we’ve taken to get these two systems to communicate makes use of a bridge agent, cryptographic proofs, blockchain smart contracts, and Unyt-based smart agreements.
This is an important step, but is still just a step in the HOT-to-HoloFuel technical migration progression. As soon as we can, we'll share what worked, what needed adjustment, and what we learned from this round of testing.
