# FAQ

## About Vault

**What is Vault?**

Vault is a decentralized crowdfunding platform built around on-chain escrow. Campaigns raise funds toward a defined goal and deadline, and the campaign's outcome determines what happens to the money.

**How does a Vault campaign work?**

A creator sets a funding goal, a deadline, and the campaign's stated purpose. Contributors send SOL into campaign-specific escrow on Solana. At the deadline the outcome is decided by the protocol's rules, not by Vault's discretion.

**Do I need a wallet?**

You need a Solana wallet to contribute. You do not need one to submit a campaign, and no Vault account, email, or registration is ever required.

## Contributions

**Where does my contribution go?**

Into that campaign's own on-chain escrow account, not to the campaign creator and not to a Vault company wallet. You can contribute from the campaign page with a Solana wallet, or send SOL directly to the campaign's funding address — either way it counts toward the goal. The funds stay in escrow while the campaign is active.

**What currency can I contribute?**

Always SOL. Some campaigns display a token or project associated with another blockchain ecosystem, but that is project identity only — there is no bridge and no multichain custody. Every Vault campaign is funded in SOL on Solana.

**Are transactions reversible?**

No. Blockchain transactions are irreversible. Once you sign and submit a contribution it cannot be undone, and sending SOL to the wrong address cannot be reversed by Vault.

## Outcomes

**What happens if a campaign doesn't reach its goal?**

Eligible refunds are processed automatically after the campaign concludes according to its rules. Any applicable refund fee is disclosed before participation and described on the Fees page.

**Do charity campaigns refund differently?**

Yes. A charity campaign shows a normal funding goal, and reaching 100% before the deadline succeeds normally. If it expires below 100% but has reached at least 20% of its stated goal, the amount raised qualifies for fulfillment instead of being refunded — a $1,000 charity goal qualifies at $200 or more. Only a charity campaign that expires below 20% is automatically refunded. Check the funding policy before contributing.

**What happens when a campaign succeeds?**

Successful funding is used to fulfill the campaign's stated purpose. Depending on the campaign, Vault may purchase or arrange the associated service or deliverable. A successful campaign does not automatically mean the creator receives the escrow balance as an unrestricted cash payout.

**Does Vault guarantee the project or token I'm funding?**

No. Vault's escrow system protects the funding process according to the campaign's rules. It does not guarantee the legitimacy, future performance, token value, business success, or conduct of a project, creator, beneficiary, or third party.

## Fees and ecosystems

**What fees does Vault charge?**

A 0.03% fee is taken when you contribute (non-refundable, does not count toward the goal). If a campaign does not succeed, a 2% processing fee applies to refunds, subject to the disclosed cap. Normal Solana network fees also apply to every transaction. See [Fees](/contributing/fees.md) for the full schedule.

**Can projects from other blockchains use Vault?**

Yes. Vault currently supports project identities from Solana, Ethereum, Base, BNB Chain, Monad, Robinhood Chain, and HyperEVM. Contributions and escrow remain SOL-based and operate on Solana.

```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
