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 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.
Jupiter Faucet is open source, reproducibly buildable and designed to decentralize control over time.
The source code, reproducible build references and governance information are available via the fixed
corner links at the bottom of the page. The core component will be blackholed, with a worst-case
scenario lifeline built into the canister. That lifeline can temporarily hand control to the
SNS DAO if a breaking change in a network dependency prevents disbursals,
and can blackhole itself again once disbursals resume.
Status: Jupiter Faucet is in the final phases of development,
with a planned launch within Q2 2026.
Source Code
Jupiter Faucet is composed of a suite of smart contracts that are all
open source.
Anyone can verify that the system components have been built from this source code by cloning the repository and running the
reproducible build script.
The build hashes produced should match the Wasm module hashes currently deployed on mainnet.
The Wasm module hashes and controllers below are retrieved on-chain from the IC management canister (`aaaaa-aa`) via `canister_info`.
Once Jupiter Faucet is governed by an
SNS DAO, changes to these mainnet components will need to pass through consensus.

Governance
SNS launch coming soon...
Prior to the SNS DAO launch this system is being developed by Alex Lorimer, the controller of the LORIMER ♾️ 🐶 known neuron, and well-known ecosystem participant.
How it works
The top-up process is intentionally simple: transfer at least
1 ICP directly into the staking account of
Jupiter Faucet's canister-controlled neuron
and set your target canister ID as the transaction
memo in plain ASCII text (see Ctrl + K 'memo' tip below). You do not need to be the owner of the canister. The 1 ICP minimum is intentional: historian keeps a durable beneficiary registry so later top-up activity can be monitored efficiently, and a much lower minimum would make registry spam far too cheap.
Transfer ICP to the long-form ICRC-1 staking account address displayed above, then paste your target canister ID into the NNS dapp memo field as plain ASCII text. Do not use the short-form legacy account identifier for this transfer: the NNS dapp requires the ICRC-1 account format to enable larger text-based memos. The faucet accepts short ASCII principal text in `icrc1_memo`; entering the target canister ID is the supported UX, and ordinary self-authenticating user principals do not fit.
1. If the memo field is hidden in the NNS dapp, press Ctrl + K, type memo, then select Show transaction memo.2. Use the long-form ICRC-1 destination address shown above, not the short-form legacy account identifier. The NNS dapp only enables larger text-based memos on the ICRC-1 address path, so that is the format required for the destination account in order for the memo to be capable of holding the target canister ID.
That’s it. With your memo declaring a canister, that canister becomes the recipient
of perpetual cycles top-ups, funded by the stake’s ongoing
rewards (proportional to your ICP commitment and any further commitments made for that canister).
A monitoring workflow will soon be introduced for visualising the impact of your perpetual top-ups.
While stake commitments can be made today, we recommend waiting for protocol completion (estimated Q2 2026).
Base maturity: 100% of the base (non age-bonus)
maturity generated from committed stake is used to perpetually burn ICP, mint cycles,
and top up the declared canister over time.
Age bonus maturity: the age-bonus component (between
0% and 20% of total maturity depending on stake age) is split
into:
• 0%–16% distributed to SNS JUP stakers in the form of newly minted nICP
• 0%–4% restaked into the
D-QUORUM
neuron to help fund decentralized due diligence of NNS proposals.
Commitment simulator: model how much ICP you may need to commit for an elected canister so Jupiter Faucet's recurring base maturity can keep pace with the canister's daily cycles burn.

This registry is historian's durable set of tracked target canisters. The registry itself is not pruned, but the per-canister histories and recent feeds shown elsewhere are bounded; full transfer history remains queryable from the ICP ledger and its archive canisters.

Commitments
Loading next historian run…
A commitment qualifies when the memo names a target canister ID as ASCII principal text in `icrc1_memo` (max 32 bytes) and the commitment is at least 1 ICP. The minimum is intentionally high to make beneficiary-registry spam expensive: historian keeps a durable beneficiary registry so it can efficiently monitor and display later cycle top-up activity. The table below is a bounded recent view: newest 500 qualifying items, newest 100 below-threshold memo items, and newest 100 invalid-memo items. Invalid memo text is not echoed back here. Full transfer history remains durably queryable from the ICP ledger and its archive canisters.

Tracker
Inspect a commitment beneficiary’s ICP commitments, observed CMC top-ups, and cycles observations.
Paste a target canister principal. If historian recognises it as a memo-registered commitment beneficiary, this pane shows memo-registered commitments, observed transfers into that canister’s CMC top-up account, and cycles observations as separate charts so the scales and meanings stay clear.
Partners
Jupiter Faucet is helping to propel big burners: projects with
meaningful, continuous cycles demand (on-chain AI and other
high-throughput workloads). By making perpetual top-ups "set-and-forget", we
aim to reduce operational friction and help these applications scale on the
Internet Computer.
Life On Ledger has so far been a stealth mode project and is still under development.
It has a strong relationship to Jupiter Faucet's early committers, and a huge demand for cycles. In short,
Life On Ledger is a massive multi-player online game in the form of an unstoppable cellular automata.
It supports up to 100K simultaneous players (potentially more with some further work) each competing to claim more territory
than their competitors in a perpetual war. To support its long-term growth,
the upcoming LOL SNS DAO will be the recipient of a
10% allocation of JUP genesis tokens.
We're confident LOL's high burn rate and affinity for a VERY large community of CA fanatics will help put the IC on the map for good.
We also recognize that unstoppable smart contracts depend on the safety and
resilience of the network they run on. That’s why we support
D-QUORUM, and why a small portion of age-bonus maturity (0 - 4% of total maturity depending on age) is
restaked into the D-QUORUM neuron to help bootstrap protocol-funded,
decentralised due diligence of NNS proposals, to strengthen Internet
Computer governance over time.
The future is arriving faster than many are ready for, and onchain governance will revolve just as much around
capable onchain AI as it does around human participation and off-chain tooling.
A stealth-mode AI project that is currently under development (and goes by more than one name) will be
the recipient of an additional 15% allocation of JUP genesis tokens. This project stands to become the largest burner
on the IC, while helping to secure the network and inform human voters of network activity in
a trust-minimised way. This project demands significant resources which will be ongoing. Jupiter Faucet will help it get there.
Stimulating the adoption of liquid staking tokens is also an important goal.
We believe nICP will help insulate ICP from price volatility.
Issuing JUP rewards as nICP also helps users maximise long-term gains with minimal effort or opportunity cost.
As the IC's leading liquid staking protocol,
WaterNeuron's nICP is the go-to choice.
We believe these strategic alliances will help decentralize Jupiter Faucet at genesis
and beyond, while also helping to elevate and secure the
Internet Computer - for the benefit of everyone building on it, everyone
staked on it, and everyone holding valuable on-chain assets.
