Impersonator

Impersonator lets you connect any Ethereum address to dapps in watch-only mode.

It supports major EVM chains such as Ethereum, Arbitrum, Optimism, Polygon, and BSC, plus various testnets.

Addresses can be entered via ENS, and no private keys are required.

You can dynamically switch the connected address and network after connecting to a dapp.

The UI shows transaction calldata generated by dapps, and Tenderly can be used to simulate transactions from the impersonated address by providing a fork id in the config.

Use cases include testing UI from a different user perspective, viewing stats on a dapp without signing into a hardware wallet, or exploring how whale wallets interact with a protocol.
