About

Not your keys 🔑

We are building a non-custodial payment layer for teams that want deterministic invoice addresses, live payment tracking, and direct settlement to the owner wallet without taking custody along the way.

Invoice addresses are deterministic and can be prepared off-chain before a customer pays. Buyers send tokens to those addresses, and when it is time to withdraw, anyone can call the contract. The contract only settles funds to the owner's wallet.

FAQ

Frequently asked questions

Everything about fees, custody, supported tokens, and integrating crypto payments.

What is SodaPop Fi (DePay)?

SodaPop Fi, also called DePay, is a non-custodial crypto payment layer. It generates deterministic on-chain invoice addresses for your customers, tracks incoming payments live, and settles every transfer directly to your own wallet. The platform never takes custody of your funds at any point.

How do non-custodial crypto payments work?

Each invoice gets its own deterministic address, computed off-chain before the customer pays. The buyer sends tokens to that address like any normal transfer. When you withdraw, a smart contract sweeps the balance and settles it only to the registered owner wallet.

What fees does DePay charge?

DePay charges a flat 0.1% fee on each settled payment. There is no monthly subscription, no setup cost, and no minimum volume. You still pay the standard network gas fee of whichever EVM chain the payment is settled on.

Which cryptocurrencies and tokens can I accept?

You can accept any ERC-20 token, including USDT, USDC, DAI and WBTC, plus native coins such as ETH, BNB and POL. Payments work across multiple EVM networks, so customers pay on whichever supported chain has the lowest fees for them.

Do I need KYC to accept crypto payments?

No. There is no KYC, no email address, no password, and no personal data collected. You connect a wallet and can start generating invoices immediately. Because funds settle straight to your wallet, no account balance is ever held on your behalf.

Can customers pay from an exchange like Binance or Bybit?

Yes. Invoice addresses are ordinary on-chain addresses, so customers can withdraw directly from Binance, Kraken, Bybit, OKX, or any wallet that supports ERC-20 transfers. No browser extension, no wallet connection, and no Web3 knowledge is required on the payer's side.

Who can withdraw funds from an invoice address?

Anyone can trigger the withdrawal transaction, which means you can automate settlement from a bot or backend without exposing your keys. The smart contract will only ever release funds to the owner wallet registered for that invoice, so a third-party call cannot redirect the money.

How do I integrate crypto payments into my app?

Use the REST API to create invoices, poll payment status, and trigger withdrawals programmatically. Typical integrations include SaaS billing, Telegram bots, marketplaces, digital product checkouts, and subscriptions. You can also share a hosted checkout link if you would rather not write any backend code.
