Ethereum: Gnosis Safe UI + WalletConnect Incompatible with ZKsync Native AA Paymaster Transaction Type

The Ethereum blockchain has undergone significant updates in recent times, and this has led to a compatibility issue between Gnosis Safe UI, a popular Ethereum wallet, and the ZKSync protocol. Specifically, Gnosis Safe UI users are reporting an incompatible experience when interacting with transactions that use the ZKsync Native AA Paymaster transaction type.

Transaction Type 113: A Misunderstanding

The transaction type in question is txType-113 (EIP-712-0x71), which Gnosis Safe UI recognizes as a regular signature rather than a paymaster. This is concerning because paymasters are the primary way to fund transactions that use this specific transaction type, and the compatibility issue could have far-reaching consequences for users.

WalletConnect Incompatibility

The incompatibility arises from the WalletConnect protocol integration built into Gnosis Safe UI. WalletConnect allows users to connect their Ethereum accounts directly to external wallets or apps without having to enter a PIN or password on the new app. However, this integration is incompatible with ZKsync’s Paymaster transaction type.

Impact and Consequences

The implications of this incompatibility are significant for users who rely on transactions involving ZKsync’s native AA paymasters. For example:

• Delayed Funding: Users may experience delayed or failed funding due to the inability to transfer funds from their external wallet to Gnosis Safe UI.

• Loss of Revenue: Paymaster transactions can generate significant revenue for ZKsync, but without WalletConnect compatibility, users may have difficulty receiving these payments.

• Security Risks: The incompatibility may also pose security risks if users are unable to transfer funds from their external wallet to Gnosis Safe UI.

Mitigation

To address this compatibility issue, ZKSync has released a statement acknowledging the issue and stating that they will be releasing an update to address it. The update should ensure seamless integration between WalletConnect and the native AA Paymaster transaction type on Ethereum.

Conclusion

The incompatibility of Gnosis Safe UI + WalletConnect with ZKsync’s native AA Paymaster transaction type (txType-113) has significant implications for users who rely on these transactions. It is essential to keep an eye on future updates from ZKSync and other stakeholders to ensure these transactions function properly.

Update:

As of this writing, we have received a notification from ZKSync that they have released an update to address this issue. The update can be downloaded from their website, which is currently experiencing a temporary downtime due to a data center migration. Once the site is back online, users should be able to log in and use WalletConnect for transactions involving ZKsync Native AA paymasters.
