Frequently Asked Questions

Donating takes less than a minute. Connect your Solana wallet (Phantom, Solflare, or Backpack), pick the campaign that moves you, and tap "Donate". Choose your amount in SOL or USDC, confirm in your wallet — and your contribution is recorded on the blockchain forever.

For now, donations go through Solana wallets. The good news: we are integrating Pix through a PSP partner so anyone can contribute directly in BRL, no crypto needed.

Yes. Every donation creates a transaction on the Solana blockchain that anyone can look up on an explorer (Solscan or Solana Explorer). The transaction signature is also stored in your history on the platform.

The refund policy depends on the campaign’s trust mode. Campaigns with milestone-based release allow refund requests as long as the funds have not yet been released to the creator. Check the campaign page for details.

No. The platform fee is deducted from the amount received by the creator, never from the donor. If you donate R 100, the creator receives R 97.50 and Kausa retains R 2.50 to sustain operations.

Your real identity is already anonymous by default — the platform only knows your wallet address. If you prefer, you can hide your address from the campaign’s public donor list.

Connect your wallet, go to "Create campaign," and fill in the title, description, goal in BRL, and deadline. Once published, the campaign is visible on the platform and can be shared via link or Blink.

The bond is a security deposit the creator makes when publishing a campaign. It serves as a commitment signal — if the campaign is completed successfully, the bond is returned in full to the creator.

When creating a campaign, you can define milestones with partial goals. Funds are released as each milestone is reached and verified, protecting donors against project abandonment.

You set the deadline when creating the campaign, with a maximum duration of 90 days. Campaigns that don’t reach their goal within the deadline can be renewed by the creator, keeping the contribution history.

Beyond the standard service, organizations can request custom solutions that include a metrics dashboard, impact reports, and dedicated support. Get in touch via the Business page.

Yes. The title, description, and image can be updated at any time. The financial goal and deadline can only be changed if the campaign has not yet received donations, to avoid changing the rules for existing donors.

Creators who handle more than R 5,000 undergo internal verification in accordance with AML/KYC regulations. The process includes document validation and, for organizations, CNPJ verification with the Brazilian Federal Revenue Service.

Reputation is a score from 0 to 100 based on five factors: campaign history, donation volume received, donor reviews, completed verifications, and time on the platform. The higher the score, the more trustworthy the profile.

Verification is performed by platform administrators. High-value campaigns undergo document review before funds are released. Any user can report suspicious content.

On the campaign page, click "Report" and describe the reason. All reports are reviewed by the team within 48 hours. Fraudulent campaigns are suspended and funds are held until the investigation is concluded.

If the creator does not update the campaign for more than 30 days, the platform sends notifications. After 60 days of inactivity, the campaign is marked as inactive and donors can request a refund of unreleased funds.

Yes. Identity verifications are valid for 12 months. CNPJ verifications follow the validity of the registration with the Federal Revenue Service. The platform notifies the creator before expiration for renewal.

Onchain means the information is recorded directly on the blockchain — a public, immutable ledger. At Kausa, every donation creates a permanent record that anyone can audit.

Kausa runs on Solana, a fast blockchain with transaction fees below one cent. This makes even small donations worthwhile.

Copy the transaction signature shown in the donation confirmation and paste it into Solscan (solscan.io) or Solana Explorer (explorer.solana.com). There you can see sender, recipient, amount, and timestamp down to the second.

Solana is an open-source blockchain network designed for fast, low-cost transactions. It processes thousands of transactions per second with an average cost below US 0.01 per operation.

No. Funds are held on the Solana blockchain, linked to the creator’s wallet address. There is no banking intermediary — the creator has direct control over the tokens received.

Yes, but on Solana the fees are extremely low — usually less than R 0.01 per transaction. The cost is paid automatically by the donor’s wallet at the time of confirmation.
