EIP-1193
Fleeting- Référence externe : https://eips.ethereum.org/EIPS/eip-1193#definitions
This EIP formalizes an Ethereum Provider API to promote wallet interoperability
minimal, event-driven, and agnostic of transport and RPC protocols
easily extended by defining new RPC methods and message event types
Historically, Providers have been made available as window.ethereum in web browsers, but this convention is not part of the specification.
