Is Petra Web free to use?

Yes! Petra Web is free to use for developers and users.

Does Petra Web work with sponsored transactions?

Yes. See Aptos developer docs (opens in a new tab) for an example of how to build a sponsored transaction.

Are there any differences between transactions sent from Petra Web via Keyless accounts vs. private key accounts?

Keyless accounts use a different signature scheme and require a different verification process on-chain. As a result, Keyless transactions are more expensive than transactions originating from a private-key account. However, due to Aptos’ scalability, gas fees are still very low even with keyless transactions.

Can a user have the same address in Petra Web and another ecosystem wallet that supports Keyless accounts?

No, address derivation for Aptos Keyless is domain specific. So, a user’s address will be unique for each application.

Is there a mobile application version of Petra Web?

No, currently there is only a browser-based version. However, Petra Web is mobile-compatible in that all interactions between the application and Connect are handled via browser pop-ups.

Is Petra Web secure?

Your Petra Web account is gated to only handle transactions through Petra Web, and can not be accessed directly by other applications. With Keyless, Petra Web servers get no access to your account, and you completely own your account with all private information stored locally. Petra Web has undergone internal and external security audits.

What should I be sure to educate my users on when using Petra Web?

The Keyless account created within Petra Web is controlled by the account used to log in (e.g. Google if ‘Sign in with Google’ was selected). If your users lose access to that account, they will no longer be able to access blockchain account(s) associated with Petra Web. In order to retain security, we recommend advising them to add backup options to their social sign-in account(s) and turning on 2FA.

My users will be signing in with their social sign in accounts. How does Petra Web protect their data?

Petra Web abides by all data protection requirements of PII. Additionally, Petra Web’s use of Aptos Keyless zero-knowledge technology ensures that all on-chain activity is obfuscated from the user’s username, maintaining on-chain privacy.
