Background
Three months ago we submitted a small proposal ($2,000 for KYC verification). It was rejected with fair and constructive feedback: prove the network publicly first, show traction, then return with a milestone-based proposal. We did exactly that.
What we delivered since then, all independently verifiable
We invite every voter to run the full privacy flow before deciding, it takes minutes with only a browser and the faucet.
What Orbinum brings to Polkadot
Polkadot has no production shielded-pool privacy layer. Orbinum is Substrate + Frontier: a shielded UTXO pool with ZK proofs (shield, private transfer, unshield, selective disclosure for compliance) combined with full EVM compatibility. Connected via XCM, it gives every parachain and every ecosystem user access to private transfers without leaving Polkadot. The codebase is public: https://github.com/orbinum/
The request
Milestone-based funding across three workstreams. Funds released per completed milestone, not upfront.
Why now
The network works. The community is real and growing. What stands between Orbinum and delivering a privacy layer to Polkadot is exactly what this proposal funds. Last time we asked before showing proof. The proof is now live, we ask the community to evaluate the work directly.
Closing
We are grateful for the feedback that shaped this proposal, it made both the project and this request stronger. Orbinum is built to be part of Polkadot, and this funding takes it from a working testnet to an audited, XCM-connected privacy layer the whole ecosystem can use.
We welcome every question, and we encourage voters to try the network firsthand before deciding. You can reach us on this thread, on Discord, or on Telegram.
Thank you for your time and consideration.

Orbinum is a privacy layer for Polkadot that lets you send tokens without anyone seeing your balance or who you are sending to. You can also choose to share your transaction details if needed for rules.
They built a working test network where anyone can try it. It has 6 nodes, a web app to shield and unshield tokens, and tools for developers. Over 36,000 transactions have been made, and more than 2,500 people have tested it.
Now they ask for money in three parts: one for a security check, one to connect with other Polkadot chains, and one to keep the network running for six months. They promise to show proof for each part before getting paid.
