About
Jupiter Faucet is a perpetual cycles top-up protocol for the Internet Computer - built to help canister smart contracts keep running indefinitely. The Internet Computer is designed for tamperproof, "unstoppable" on-chain services; Jupiter Faucet focuses on the practical part: making sure canisters don’t run out of cycles, even if nobody is maintaining the project.
The perpetual top-up workflow is intentionally designed to be so simple that anyone can carry it out as a one-off operation directly from the NNS dapp using the enhanced transfer and memo flow - no further setup required.
Jupiter Faucet is built to propel big burners, including cycle-intensive on-chain AI workloads such as WORDY, helping projects get the most out of ICP→cycles conversion over the long run.
Open source, reproducible builds will be published soon, along with further announcements. These include decentralization of peripheral components via an SNS launch. The core component will be blackholed, with a worst-case scenario lifeline built into the canister. The lifeline mechanism is capable of temporarily reassigning its controller to the SNS DAO in the event that a breaking change has been applied to network dependencies (protocol canisters running in system subnets) preventing disbursals. Similarly the mechanism is capable of blackholing itself once disbursals begin flowing again.
Status: Jupiter Faucet is in the final phases of development, with a planned launch within Q2 2026.
