This only applies if you are using @gelatonetwork/relay-sdk v3 or contracts from the package @gelatonetwork/relay-context v2
Gelato Relay ERC2771 proxy contracts are immutable for security reasons. We have deployed new versions of our ERC2771 proxy contracts with enhanced security: GelatoRelayERC2771.sol and GelatoRelay1BalanceERC2771.sol, new addresses of which you can find here. To support these new contracts, Relay Context Contracts found in the package @gelatonetwork/relay-context have been updated to version v3, along with the Gelato Relay SDK package @gelatonetwork/relay-sdk, which has been updated to version v4. Gelato Relay continues to support ERC2771 contracts that inherit from the legacy @gelatonetwork/relay-context v2, so you can upgrade at your own convenience. Nevertheless we recommend you to upgrade as soon as possible to ensure optimal security, features and support.

​
Package and Contract Compatibility Matrix

Please note that contract addresses differ on zkSync Era.
Using @gelatonetwork/relay-sdk v3 with contracts inheriting from @gelatonetwork/relay-context v3, or using @gelatonetwork/relay-sdk v4 with contracts inheriting from @gelatonetwork/relay-context v2 won’t work, as they refer to different Gelato Relay ERC2771 contracts.

​
Migration Steps

  1. If you deployed contracts that inherit from @gelatonetwork/relay-context - update the package version and either upgrade or redeploy your contracts.
  2. If you are using sponsoredCallERC2771 in combination with ERC2771Context.sol - make sure to use the new GelatoRelay1BalanceERC2771.sol contract address as the trustedForwarder which you can find here.
  3. If you are using @gelatonetwork/relay-sdk - update the package version in your project.
  4. Make sure you use your newly upgraded/deployed contract addresses with the updated Gelato Relay SDK package.
If you cannot upgrade or redeploy your ERC2771-compatible contracts, please contact us to find a future-proof solution together.
