Project Overview

RESEARCH CONTEXT

Xcellar is an early-stage project with an anonymous development team — the same team behind Sentinel. The project brands itself around a proprietary "Fawkes Formula" privacy protocol, but no technical documentation or source code for that protocol has been published. Our research scope is limited to the on-chain footprint: the XCL token contract and the rewards distribution contract.

NOTE TO DEVELOPERS

Please do not hesitate to reach out to us if we have documented anything inaccurately, if anything is out-of-date, or in general if there is any way that we could better support the project.


Xcellar brands itself as a privacy-focused protocol "Powered by Fawkes Formula." The Fawkes Formula is described as a privacy mechanism for transferring funds, though no public specification or verified implementation exists on-chain at the time of writing.

Xcellar sits at the center of a small ecosystem. Sentinel explicitly ties itself to Xcellar — the Sentinel website footer reads "powered by xCellar: Fawkes Formula," and the Sentinel Distributor allocates 30% of claimed profits to XCL buyback and burn. The stated relationship is symbiotic: Sentinel generates trading revenue, burns XCL to reduce supply, and uses the Fawkes Formula protocol for fund transfers — which in turn generates rewards for XCL holders.

The Reward Pool Registry was deployed on the same day as the XCL Rewards v1.0.0 upgrade, by the same deployer address. It implements a paid registration model (0.001 ETH) with off-chain reward crediting by a designated distributor EOA. As of March 29, 2026, the contract holds 0 ETH — registration fees are forwarded to a fee recipient and no rewards have been deposited.
