TLDR: Private, accountable donations to causes that are dangerous to support openly. Built on 0xbow Privacy Pools v2, Cloak breaks the public link between donor and cause.
Full description
Cloak - give to what you believe in, without becoming a target.
In dozens of countries, donating to independent media, a human-rights group, an LGBTQ+ org, or humanitarian aid is treated as a crime. A ballerina got 12 years for a ~$50 gift to a Ukrainian charity https://www.bbc.com/news/articles/c0l005w2j86o
in Belarus people are jailed over $15 donations https://www.rferl.org/a/belarus-war-ukraine-russia-prison-punishment/33631246.html

This is not one country’s problem.
On every continent, defending democracy, and basic human rights is being treated as a crime
Mindblowingly, 72% of the world lives under repressed or closed civic space https://monitor.civicus.org/globalfindings_2025/innumbers/- i.e. in their countries, donations to political parties, independent media and press, human rights projects (minorities, women, LGBTQ+), even environment activists can be dangerous
The problem for many people is donating became a legal risk, and every traceable donation (card, bank, or a public blockchain) is permanent proof of who you backed.
What Cloak does. Cloak is a UI on top of 0xbow's Privacy Pools v2. You deposit into a shared pool, then the gift reaches the cause from the pool with no on-chain link back to you - while the Association Set still lets the cause prove the funds are clean. Accountable privacy, not secrecy.
How it works (live on Sepolia).
Connect wallet → real Privacy Pools v2 deposit (verifiable on Etherscan) → once the Association Set approves it, withdraw privately to the cause through a relayer.
Donate to a set of listed projects, to a custom ERC20 address, or create and list a new initiative (+a widget to make secure donations to embed in your website)
Two modes: 1-step deposit (user deposits into a pool and the wallet owner have to withdraw from the pool)
or, or 2-step deposit-then-withdraw (user deposits into a pool and then pushes the donation to the receiver's wallet after the monitoring has been passed)
Plus an AI advisor (Claude) that gives a personalized, honest read on your risk, an Impact Wall (transparency), self-serve donation pages + an embeddable widget, and an explicit "what Cloak does and does NOT protect" panel.Tech. Next.js + wagmi/viem, @0xbow-io/privacy-pools-v2-sdk (real deposits, ASP, relayer withdrawals), Claude for the AI advisor, Sentry for monitoring.
Honest scope: the deposit is real and on-chain today; the private withdrawal completes once the Association Set approves the deposit. Causes shown (Meduza, OVD-Info, Razom for Ukraine) use their real addresses; the demo runs on testnet.
Built for: 0xbow (UI on Privacy Pools v2), Blockchain for Good, the AI x Web3 main track, and Mood (AI use case).
