7702 Bundler Demo

This demo showcases how to utilize EIP-7702 to sponsor a userOperation originating from a EOA by using the pimlico_experimental_estimateUserOperationGas7702 and pimlico_experimental_sendUserOperation7702 endpoints.

This demo is ran on the Odyssey Testnet and uses a modified version of ETH-Infinitism's Simple Account to accommodate for EIP-7702. Instead of using a storage slot to hold the account signer/owner, the signer/owner is set to address(this).

Running

export PIMLICO_API_KEY=pim_xxxxxxxxxxxxxxxxxxxxxx

pnpm install

pnpm run start
