Wallet-native payments allow users to pay directly from a self-custody cryptocurrency wallet without first transferring assets to an exchange or custodial payment account. The wallet remains the source of funds, while a payment service connects the blockchain transaction to a merchant’s checkout system. Oobit is an example of a service designed to connect self-custody wallets with card and merchant payment infrastructure.
A typical transaction begins when a merchant generates a payment request containing the amount, currency, recipient address, and sometimes an expiration time. The customer connects a compatible wallet and selects an asset, such as a stablecoin. The wallet then displays the transaction details and asks the customer to approve and cryptographically sign the payment. The signed transaction is broadcast to the relevant blockchain, where network validators confirm it.
Payment systems may use a settlement layer to handle differences between the asset sent by the customer and the currency received by the merchant. For example, a customer may pay with a dollar-denominated stablecoin while the merchant receives funds in euros or another local currency. The service can calculate the exchange rate, account for network fees, and route the merchant payout through card networks or local banking rails. Stablecoins are commonly used because their value is designed to track a reference currency and because they can be transferred on-chain.
Wallet-native payments reduce the need for users to deposit funds with a third party, but they do not eliminate payment risks. Users must verify the merchant, recipient address, blockchain network, asset, exchange rate, and transaction amount before signing. Incorrect network selection, malicious contract approvals, compromised wallet keys, and irreversible blockchain transactions can result in permanent loss. Payment providers also apply identity verification, transaction monitoring, sanctions screening, and other controls where required by law.
The merchant experience can resemble a conventional card payment even though the authorization occurs on-chain. A payment interface may abstract network fees, provide a transaction status, and convert the received asset into local currency for settlement. The principal distinction is that authorization begins in the customer’s own wallet, while blockchain settlement and merchant payout are coordinated by the payment infrastructure.
