The plan promises execution results before settlement, but credibility will hinge on the size and enforceability of the financial backstop and SLAs.
Puffer said on Sept. 22 that Google Cloud will operate a gateway for its Ethereum transaction infrastructure, issuing “preconfirmations” that promise the result of a user’s transaction before the base layer settles it. Puffer said its UniFi network would be the first to use the service. As of Sept. 23, both UniFi and Puffer Preconf were still running in a testing environment, CEO Amir Forouzani told CryptoSlate, and their performance with real customer funds has yet to be demonstrated.
The draw is obvious to anyone who uses a payments app: when the screen says a transfer is complete, you act on it. Preconfirmations aim to give crypto users that same confidence sooner by having an operator stand behind an early answer.
Ethereum’s base layer relies on many computers agreeing on a shared record. Blocks are proposed every 12 seconds, and stronger confirmation—finality—typically takes minutes. Many applications run on rollups that process transactions separately and post data to Ethereum for settlement, often offering users faster, operator-level confirmations while the base chain completes its work.
Puffer’s twist is to put explicit financial backing behind an early promise about the transaction’s outcome. As Forouzani described, if a user swaps 1 ETH for 2,600 USDC, the gateway would promise the execution result—including the amount received—rather than merely promising to include the transaction in a block. Inclusion alone does not guarantee the price or fill a user expects.
The trade-off is risk allocation. A preconfirmation shifts some settlement and execution risk from the user to the gateway that issues the promise. That makes the guarantee’s economics central: the size and source of the financial backstop, the service-level agreements that define compensation for failures, and how disputes are resolved. Without clarity on those elements, a fast “done” screen is trust in new clothing.
Operator design also matters. Puffer said Google Cloud would operate the gateway that receives transactions and issues guarantees. Concentrating that role in a single gateway can simplify accountability but also centralizes trust and creates a single point of failure. A multi-operator model could mitigate that, but Puffer has not yet detailed how the role will be shared.
What to watch next
- Collateral and liability: audited visibility into the funds backing preconfirmations and who bears losses when guarantees fail.
- SLAs and dispute process: specific timelines and payouts for missed or incorrect guarantees.
- Operator structure: whether additional gateways join and how users/apps can choose among them.
- Production performance: latency, failure rates and incident handling once real money flows through UniFi and Preconf.

🧠 HafidWatch Take
Preconfirmations transfer settlement risk from users to the gateway, making the size, terms, and enforceability of the financial backstop crucial to the guarantee’s value. With Google Cloud operating Puffer’s gateway in testing, the key factors to watch are transparency around collateral, service-level agreements, and how incidents are managed—factors more important than demonstration latency.
