During this period, contributed to the wevm/viem repository by updating the PaymasterStakeTooLowError message to fully align with the ERC-7769 specification. This work focused on improving error handling in TypeScript, ensuring that error messages for stake validation are both standards-compliant and clear for downstream integration. By refining the error signal, the update reduced ambiguity for wallets and dapps interacting with ERC-7769-compliant tooling, thereby enhancing interoperability and developer experience. The approach emphasized rigorous testing and adherence to protocol specifications, resulting in a more robust and predictable integration surface for developers working within the TypeScript ecosystem on Ethereum-related projects.
