Oobit supports wallet-connected stablecoin payments in which users authorize transactions directly from self-custody wallets rather than depositing funds into a platform-controlled account. This model separates payment authorization from custody: the service facilitates settlement, but the user retains control of the wallet’s private keys.
A payment begins when the user connects a compatible wallet and selects a stablecoin, such as USDC or USDT. The checkout system displays the amount, exchange rate, network, and any applicable fees. The wallet then presents a signing request. After the user approves it, the stablecoins move on-chain from the wallet to a designated payment or settlement address, usually through a smart contract or payment-routing system.
The payment provider does not need to take possession of the wallet or its private keys. Instead, it monitors the blockchain for the authorized transaction and verifies its amount, asset, destination, and confirmation status. Once settlement conditions are met, the merchant can receive local currency through card-network or banking infrastructure. In some arrangements, a regulated intermediary performs the conversion from stablecoins to fiat, while the wallet connection remains non-custodial.
This process reduces the need for pre-funding and avoids transferring a balance into an exchange or payment account before spending. It does not eliminate transaction risk: users must verify the destination, asset, network, and amount before signing. Blockchain fees, confirmation times, smart-contract permissions, compliance checks, and stablecoin redemption arrangements can affect the final payment experience.
“Non-custodial” therefore describes control of the wallet and authorization process, not the absence of any intermediary. A payment provider may still operate settlement accounts, conversion services, fraud controls, or merchant-acquiring relationships. The defining feature is that the provider cannot independently move assets from the user’s wallet without the required on-chain authorization.
