WIP. I still need to address comments in the old PR here. Opening this now to secure a caip number since we have need for this in our implementation we will soon be exposing publicly |

| ## Security Considerations | ||
| <!--Please add an explicit list of intra-actor assumptions and known risk factors if applicable. Any normative definition of an interface requires these to be implementable; assumptions and risks should be at both individual interaction/use-case scale and systemically, should the interface specified gain ecosystem-namespace adoption. --> | ||

| While web extensions could realize the benefits of `externally_connectable` without using it with a standardized interface, this would mean that every web extension would have to ship a provider library that worked specifically for their interface and that Dapps would need to import them. It wouldn't be feasible for Dapps to import every single web extension's specific provider implementation, making this approach less viable. | ||

| Web extension inter-operability is the key to enabling generalized provider implementations. Generalized provider implementations allows for convenient adoption by Dapps, leading to more wide spread adoption of the standard as a result. | ||

reminder: maybe mention other uses of the transport being possible?

This CAIP discusses the motivation, specification, and rationale for a proposal aimed at improving how web extension wallets interact with websites. It outlines the current method of injecting JavaScript provider APIs into websites, its advantages, and its numerous disadvantages, such as security concerns, performance issues, and the risk of breaking websites. An alternative strategy is proposed that specifies a standard communication specification over a new transport layer which enables websites to be able to embed their own provider as a library, addressing the disadvantages of injecting providers into websites and improving web extension interoperability as a whole.
