Rivet

Rivet is a browser extension that enables developers and testers to inspect, debug, modify, and manipulate the state of Ethereum: accounts, blocks, contracts, and the node itself.

Rivet is also compatible with any production dApp, meaning you can simulate any type of action from either an Account attached on the Anvil instance, or by 'impersonating' another Account on the network.

Rivet is designed to be used alongside and with other consumer browser wallets like MetaMask or Rainbow to provide more engrained developer and tester tooling and workflows for Ethereum.
