Security at Kausa

Your donations are protected by smart contracts on Solana, not by promises. See how each mechanism works in practice.

Onchain Transparency

Every donation on Kausa is a real transaction on the Solana blockchain, recorded on the public ledger and verifiable by anyone. There is no black box: the creator's wallet address, the transferred amount, and the block timestamp are permanently accessible.

  • Transactions confirmed in under 1 second on Solana
  • Unique tx signature for each donation — searchable on any explorer
  • Campaign balance visible in real time on the public ledger
  • No intermediary can alter or erase the history

Milestone-Based Releases

Raised funds don't go directly to the creator. They are held in a vault PDA (Program Derived Address) on Solana — an address controlled exclusively by the smart contract, not by a Kausa bank account.

Releases happen in tranches tied to concrete project milestones. The creator must prove progress on each stage, and the release is only authorized after administrative verification.

Vault PDA

Funds custodied by smart contract on Solana — out of reach of Kausa or the creator until verification.

Verification

Admin confirms evidence of progress before each tranche release.

Partial release

Only the tranche for the completed milestone is released — the rest remains in the vault.

How the vault works

When a donor contributes, SOL (or an SPL token) is transferred to a vault PDA on Solana — an address deterministically derived by the program, with no corresponding private key. This means no one, including the Kausa team, can move the funds arbitrarily.

The smart contract defines the release rules: who can withdraw, when, and under what conditions. The money doesn't pass through a bank account, isn't held in platform custody, and doesn't depend on trusting third parties — it depends only on the auditable code on the blockchain.

In short: the funds are on the blockchain, not in Kausa's bank. The smart contract is the guardian.

Creator Bond

To create a campaign on Kausa, the creator deposits a guarantee (bond) in SOL. This guarantee is held in the smart contract for the entire life of the campaign and serves as a real financial commitment to donors.

Deposit on creation

The bond is deposited when the campaign is published. Without a deposit, the campaign is not published.

Return on completion

If the creator meets all milestones and delivers on promises, the bond is returned in full.

Slash for abandonment

If the creator abandons the campaign or fails to respond to disputes, the bond is slashed and redistributed to donors as partial compensation.

Donor Protection

If a campaign reaches its deadline without meeting the goal, the smart contract enables automatic refunds. The donor can withdraw the contributed amount directly from the vault, without depending on approval from Kausa or the creator.

  • Refund automatically enabled by the contract when the deadline expires without meeting the goal
  • The donor initiates the withdrawal with their own wallet — no forms or support requests
  • Proportional to the donated amount, minus network fees (gas)
  • Process recorded onchain with the same transparency as the original donation

What happens when something goes wrong

Kausa has a structured dispute flow to protect donors when a campaign doesn't deliver on its promises.

  1. 1

    Donor reports a problem

    Any donor can open a dispute reporting what went wrong — delays, lack of communication, or misconduct.

  2. 2

    Administrative review

    The verification team analyzes the evidence, contacts the creator, and assesses whether the campaign terms were violated.

  3. 3

    Bond slash

    If the violation is confirmed, the creator's bond is slashed. The amount is redistributed proportionally to the campaign's donors.

  4. 4

    Refund enabled

    Remaining funds in the vault are released for withdrawal by donors. The entire process is recorded on the blockchain.

Productive Capital

While funds wait in the vault for milestone-based releases, they can work. Kausa is integrating yield protocols on Solana (such as the USDC supply pool on Kamino Finance) so that idle capital generates real yield.

Donors and creators benefit from time: the more disciplined the milestone progress, the more yield accumulates in the vault before each release.

Feature under development. Productive capital will be activated after the Kamino integration contract audit.
