Terms

Testnet only

• Whiteflow uses test USDT on Whitechain testnet. No real money moves.
• To get test funds, claim WBT at faucet.testnet.whitechain.io and swap some to USDT on testnet.yetitrade.fi. The app has no faucet button.

Who holds the money

• Each payment settles straight to the business's own wallet, in the same transaction. Whiteflow never holds it.
• A customer approves an exact amount, so a payment can't be short or over.
• Refunds are sent from the business's own wallet.

Fees

• A flat 0.10 USDT per payment. On a sale it comes out of the payment; on an invoice the payer adds it on top. Details on Pricing.
• The contract owner can change the fee, but the payments contract never lets it go above 0.25 USDT.
• Whiteflow's relayer pays the network fee for payments. Refunds and withdrawals pay their own, from the business's wallet.

If Whiteflow is down

The payment functions are open to anyone, so a signed payment can still be submitted without our relayer. The code is open source under the MIT license.

Admin powers on testnet

One key is both the compliance admin and the owner of the contracts. It can pause payments, decide who may invest, move claims between eligible investors, freeze claim units and revoke an investor's eligibility.

Limits today

• Investor checks (KYC) are simulated.
• On testnet a claim locks 60 seconds before it is due, with a 120-second grace period.
• There is no default or recourse process: a claim that is never repaid stays outstanding.
• A business could take sales outside the checkout.
• Investor caps are enforced by our server, not by the contract.
• Invoice repayments are limited to 10 an hour per payer.
• When the relayer's daily network fee budget runs out, relaying pauses until the next day.
