Learn more about how Privy supports each step below. ## Webhooks Privy sends real-time notifications for transaction status changes, deposits, and withdrawals. Your app can use webhooks to trigger downstream actions like updating balances, sending confirmations, or executing follow-up transactions. Privy also provides REST APIs for querying transaction status and balances on demand. Monitor deposits and withdrawals. Track transaction status changes. Query transactions and balances. ## Gas management Gas sponsorship removes the need for wallets to hold native tokens for fees, creating a frictionless experience without the complexity of managing gas yourself. Your app can combine gas sponsorship with [policies](/controls/policies/overview) to control which wallets can use sponsored gas and for what transaction types. Learn how gas sponsorship works. Configure gas sponsorship for your app. ## Funding Privy supports multiple ways for users to fund their wallets, including card payments, wallet transfers, exchange withdrawals, and bank transfers. Your app can configure which methods are available and prompt users to fund directly in the interface. Explore all funding methods.
