GENERAL SETTINGS

Generate contract metadata. Generate a JSON file in the contract folder. Allows
to specify library addresses the contract depends on. If nothing is specified,
Remix deploys libraries automatically.
Always use Javascript VM at load
Word wrap in editor
Enable code completion in editor.
Display gas estimates in editor.
Display errors in editor while typing.
Enable Personal Mode for web3 provider. Transaction sent over Web3 will use the
web3.personal API.  Be sure the endpoint is opened before enabling it. This mode
allows a user to provide a passphrase in the Remix interface without having to
unlock the account. Although this is very convenient, you should completely
trust the backend you are connected to (Geth, Parity, ...). Remix never persists
any passphrase
Enable Matomo Analytics. We do not collect personally identifiable information
(PII). The info is used to improve the site’s UX & UI. See more about Analytics
in Remix IDE & Matomo
