Questions and answers

A place where causes ask many people for a little. Anyone can share a project that needs help, supporters give as little as 1 USDC straight to the project's own wallet, and everyone votes for free.

We never hold your gifts: they travel from the giver's wallet to the project's wallet on the Solana network, where anyone can check them. Read more on the about page.

• Rounds are calendar weeks: they start on Monday at 00:00 UTC and end the next Monday at 00:00 UTC. Every approved project that is still active takes part automatically.
• Voting is free and you do not need an account: you get one vote per week, as a guest or signed in (we email a code, no password). Either way you pass five quick security checks the first time you vote in a week, with no email, phone number or donation. A guest vote is tied to this browser (a cookie), so find it again in My vote.
• To keep voting fair, one internet connection can unlock at most 5 guest votes in 12 hours, which is plenty for a family or an office. Past that, wait a little or sign in with your email: signed-in votes are not counted against it.
• You can withdraw your vote or move it to another project any time before the round ends: only your last vote counts. My votes shows where it is.
• Vote counts are public and live. The three leading projects wear a gold, silver and bronze ribbon.
• Votes can be moved or withdrawn even when the project has been finalized meanwhile; nobody can vote for a finalized project.

Find a project in the projects list and press "Vote for this project" on its page.

The project with the most votes when a weekly round closes. It is featured on the home page as the previous week's UNO. A round with no votes has no UNO, and a project can win several weeks in a row.

On a tie, every tied project is a UNO. When a prize is paid, the winners' share is divided equally between them: two tied projects get half each, three get a third each, and so on. The details are in the terms of use.

The prize comes from the $ONE token, which is still in development. Until it exists and its creator fees add up, there is no Community Fund and no prize is paid; rounds and results work as usual. This is the one case where money passes through us: gifts to projects always go straight to the project's wallet, but the fund is received by OneForUno and our team pays the winners manually, after review.

You need a Solana wallet with some USDC in it (see how to create one). Then, on the project's page:

1. On a phone or computer with a wallet: press "Give 1 USDC with a Solana wallet". Your wallet opens with the gift filled in; check it and confirm.
2. From your phone, while looking at a computer: scan the QR code with Phantom or Solflare.
3. Any amount, from any wallet or exchange: copy the wallet address shown on the page and send USDC to it.

Gifts on the blockchain cannot be reversed. We review every project before it is shown, but we cannot promise how the money will be used: read the project, and give to causes you trust.

OneForUno takes nothing: gifts go wallet to wallet and never pass through us. The Solana network charges a fee of less than one cent, paid in SOL by the sender (see do I need SOL?).

The very first USDC a wallet receives also costs the sender a small one-time deposit (about 0.002 SOL) that opens the wallet's USDC account. Your wallet shows the exact cost before you confirm. Exchanges charge their own withdrawal fees.

It is the USDC in the project's wallet right now, read from the blockchain. It goes down when the owner spends money, so it is not the total ever received. The full history of every wallet is public: use the "View the wallet on Solscan" link on the project page.

Projects whose owners accept sponsors show a "Sponsor this cause" button on their page; you find them with the "Accepts sponsors" filter. You choose one of your sponsor profiles (a name, logo, description and links, for yourself or for a company), an amount in USDC, and whether this sponsorship is public or anonymous. Then you pay with your Solana wallet, straight to the project's wallet: OneForUno never receives the money and takes no commission.

Every payment request carries a unique reference. We read the blockchain and the sponsorship counts only once a finalized transaction sends exactly that amount of USDC to the project's wallet with that reference. Nothing you type can mark a payment as done. Public sponsors are listed on the project page and in the sponsor directory, ranked by verified public contributions.

A verified payment proves that money was sent, not who sent it: sponsor names and logos are given by the sponsors.

On OneForUno it is anonymous: the project page shows only the amount and the date, under "Anonymous contributions", and it does not count towards your profile's public total or ranking. You still see it in your own sponsor profile.

The blockchain is public, though. Anyone can see the transfers a wallet receives and where they came from, so someone who knows your wallet can link the payment to it. For more privacy, pay from a wallet that is not linked to your name.

A wallet is a free app that holds your crypto. It takes about five minutes to set up, and it is needed by everyone who submits a project (to receive gifts) and by everyone who gives.

1. Install a wallet app, from the official site only

   We suggest one of these two, both free and made for Solana, on phones (iOS, Android) and as a browser extension:

   • Phantom: phantom.com
   • Solflare: solflare.com

   Type the address yourself or use the links above, then follow the site's links to the App Store, Google Play or your browser's extension store. Do not click ads in search results: fake wallet sites that steal money look exactly like the real ones.

2. Create a new wallet

   Open the app, choose "Create a new wallet" and set a password or PIN. That password only locks the app on this device; it is not what protects your money. The next step is.

3. Write down your secret recovery phrase

   The app shows 12 or 24 words. They are the key to your money. Write them on paper, in order, and keep the paper somewhere safe (two places is better). No screenshots, no photos, no notes in the cloud, no emails to yourself.

   Anyone who has these words can take everything in the wallet. If you lose them and your phone, the money is gone: nobody can recover it, not the wallet company and not us. OneForUno will never ask for them.

4. Copy your Solana address

   In the app, press "Receive" and pick Solana (Phantom also shows addresses for other networks: use the Solana one). Copy the address. It is 32 to 44 letters and digits and never starts with "0x"; an address that starts with "0x" belongs to another network and will not work.

   Your address is public: share it freely, it only lets people send you money.

5. Add it to your project

   In the project editor, paste the address in the "Donations" step and press Validate. We check that it is a real personal wallet on Solana (a new, empty wallet is fine) and give you a link to see it on Solscan. Check that the first and last few characters match the ones in your app.

6. Test it before you share your project

   Ask a friend to send you 1 USDC, or send a little yourself, and check that it shows up in your app and on Solscan. Then share your project with confidence.

Next: keep your wallet safe and turn USDC into money in your bank.

• Never share your recovery phrase and never type it into a website, a form or a chat. Only into the official wallet app, when you restore a wallet yourself.
• Nobody from OneForUno, Phantom or Solflare will contact you to "verify", "sync", "unlock" or "fix" your wallet. Such messages (email, Telegram, X, WhatsApp) are scams.
• Ignore tokens and NFTs you did not expect. Scammers drop them into wallets with links to sites that empty the wallet. Do not open their links or try to sell them; hide them in the app.
• Read before you approve. Your wallet asks you to confirm every transfer and signature. If you do not understand what a site asks for, reject it.
• Check you have the real USDC. It is issued by Circle and wallets show it with a verified mark. Its token address on Solana is EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v. Fake "USDC" tokens with other addresses exist.
• Keep your phone and the app up to date, and keep the app lock (PIN, face or fingerprint) on.
• For larger amounts, consider a hardware wallet such as Ledger; it works together with Phantom and Solflare and keeps the key off your phone.

We strongly suggest a wallet you control (Phantom, Solflare or similar) instead of a deposit address from an exchange account. The exchange owns that address: it can change it, move the money to its own wallets (your project would then show nothing raised), refuse transfers it does not expect or freeze the account.

You can still use an exchange later, to turn USDC into money.

To receive gifts: no. Your wallet can receive USDC while it holds nothing else.

To send or exchange USDC: yes, a little. Every transfer on Solana pays a tiny fee in SOL, the network's own coin. About 0.01 SOL is enough for many transfers. You can buy it inside the wallet app or send it from an exchange (choose the Solana network).

1. Open an account at a well-known, regulated exchange that works in your country and supports USDC on Solana.
2. In the exchange, ask for a USDC deposit address and choose the Solana network.
3. From your wallet, send a small amount first to that address. When it arrives, send the rest.
4. Sell the USDC for your local currency in the exchange and withdraw it to your bank account.

Some wallet apps also offer to sell through partners. Fees, limits and identity checks depend on the service and on where you live, and gifts may have tax rules in your country. This is general information, not financial or tax advice.

Sign in and press "Submit a project". The editor walks you through a few steps: the basics (title, category, summary, goal), your story, pictures, documents, the donation wallet, contact details and links, then whether you want votes and sponsors. You can save a draft at any time and come back later. When everything is ready, press "Send for review".

Submitting is free. For now each account can have one project (a draft counts too). You need a Solana wallet: here is how to create one.

Projects take part in the weekly voting rounds unless you switch on "I do not want votes": the project then gets its public page and can receive donations and sponsors, but never enters a round.

A person on our team reads every project before it is shown; this can take a few days. Once sent, its status is Pending, and Under review when a reviewer picks it up (you see both in My projects). We may approve it, or send it back with a note saying what to change; you get an email either way. Fix what was asked and send it again.

While it waits for review the project cannot be changed. If you need to change something, press "Cancel review": it goes back to draft, and when you send it again it waits for review from the start.

Once approved, the project gets its public page, which you can share right away to collect votes and gifts.

Voting always starts on a Monday. A project approved during a week joins the weekly rounds on the first Monday after its approval, at 00:00 UTC, even when it is approved on a Monday. There is nothing to press: it enters the round by itself.

Its public page can open earlier. When you send the project you choose when the page opens. With As soon as it is approved (the recommended choice) the page is public the moment we approve it: you can share it and receive donations and sponsors straight away, but nobody can vote for it until that Monday. With On the first Monday after approval the page and the voting both start that Monday and nothing is public before.

From the Monday voting starts it takes part in every weekly round (Monday 00:00 to the next Monday 00:00 UTC) for 14 days, which is two rounds, with no queue and no limit on places. The days are counted from that Monday, so the time before it is a bonus.

When the 14 days are over the project is finalized: nobody can vote for it or sponsor it any more, and its page shows whether it reached its goal, based on the USDC in its wallet at that moment.

In special cases we can move the end date of a project (for example when its owner asks for more time and we agree), and a few projects, such as the ones that support OneForUno itself, have no end date at all: they show ∞ instead of a date. All dates and times are in UTC.

• Cover (optional): one wide picture, best at 1200 × 630 pixels or larger.
• Gallery: 1 to 10 pictures (PNG, JPG, GIF or WEBP), up to 2 MB each. Hidden data such as the GPS location is removed.
• Documents: up to 20 (PDF, DOCX, TXT or pictures), up to 10 MB each. They are private by default (only you and our reviewers see them); make one public to show it on the project page.

Yes, until it ends. Press "Edit" on the project in My projects: you change the text, the category, the location, the contact details, the links, the cover, the pictures and the documents, then send your changes for review. We check them by hand, files included, and approve them all together; until then your page stays exactly as it was approved, so voters and givers always see something we reviewed. Once approved, the page says when it was last updated.

The goal, the wallet and taking part in the voting rounds cannot change, because supporters gave to them. Changes can be sent 3 times in 7 days, so gather everything first. Made a document public by mistake? "Hide now" makes it private at once, without review. If the wallet really has to change (for example its key was lost), suspend the project from My projects and write to us with its link.

Robots read web pages looking for email addresses and phone numbers to send spam. Contact details are shown only after a click, which stops them but costs you nothing. The project's owner chose to share these details; we do not check them.

Press "Report this project" at the bottom of its page, or contact us with its link. A person reads every report and we look at the project again.

Every account gets a username such as "user_12345678". It is shown on your projects, together with your picture if you add one; your email never is. Change both on your profile: 3 to 24 letters, digits or underscores, starting with a letter, and not already taken.

You can change your username whenever you like, but only once every 7 days: change it today and you can change it again after 7 days. The old name is kept for you for 30 days, so nobody else can take it right away and pass for you. Your projects, votes and gifts stay yours; they simply show the new name.

Every username shown on the site, for example under a project's title, is a link to a page of that person. By default that page is private: it shows only the username and picture, with a note that the profile is private.

On your profile you can turn the page public and, if you like, write a few words about yourself. A public page shows your username and picture, the date you joined, your text and your projects that are live. Your email, your votes and the projects you sponsor are never shown. You can turn it off again at any time.

The address of your page does not change when you change your username: the old address keeps working and shows the new name.

On your profile, press "Delete my account" and type your username to confirm. Your account, projects and sponsor profiles leave the site at once. A project in the round being voted leaves it and loses its votes there.

For 30 days you can change your mind: sign in with the same email and choose "Restore my account". We email you the date and a deletion code. After that the deletion is final, and signing in with that email creates a new, empty account. A single project or sponsor profile can be deleted (and restored for 30 days) the same way.

Gifts and sponsorships already sent are on the blockchain and stay in the wallets that received them; deleting the account does not touch any wallet. Sponsorships stay in the projects' totals, shown as anonymous.
