How does the RAILGUN and Stripe integration improve privacy?

By using Stripe webhooks to trigger RAILGUN shielded transfers, you decouple your fiat payment identity from your on-chain transaction history, ensuring enhanced financial privacy.

What is required to set up the Stripe webhook connection?

To initiate the automation, you must connect your Stripe account and provide your secret API key to allow B3OS to securely listen for payment events.

Can I automate gas funding through this integration?

Yes, once a Stripe payment is verified via webhook, the workflow can be configured to execute private gas funding within the RAILGUN ecosystem.

Is my Stripe API key stored securely?

B3OS utilizes industry-standard encryption to ensure your Stripe secret API key is handled securely and only used to facilitate the specified automation workflows.

Wallet: Privately Fund a New Wallet with Anonymous ETH

Funds a fresh wallet with gas in ETH) on any chain (default:Base) without leaving an onchain link back to your source wallet. This workflow shields USDC from your source wallet on Arbitrum into RAILGUN, waits in the shielded pool to build anonymity, then creates a new destination wallet and unshields the USDC to it via a public relayer. From there it swaps the USDC to ETH and bridges it to the chain of your choice ### Quick Setup: 1. Import your wallet or use your B3OS Treasury Wallet as the source wallet that holds USDC on Arbitrum 2. Set the amount of USDC to shield and use for funding 3. Choose how long to wait in the shielded pool before unshielding (longer \= stronger privacy) 4. Pick the destination chain where the new wallet should receive ETH 5. Set the target ETH amount to leave in the new wallet 6. Confirm the RAILGUN relayer to use for the unshield step 7. Run the manual trigger whenever you want to fund a fresh wallet 8. Test and publish!
