Integrating Offramp/Onramp with a widget in-app that accommodates local payment methods

Is it possible to integrate a feature that allows developers to build an in app widget that extends the convenience of fiat-crypto exchanges with local payment methods that might not necessarily be globally popular, as a way of extending accessibility to crypto and enabling convenience for exchanges through metamask. In my country Uganda for instance, CEXs are a natural service of choice for users but the burden of accessible token limitation restricts certain categories of users from accessing the service, compelling them to make avoidable bridging transactions just to be able to offramp especially. For instance I’d have to bridge from Lisk to Eth or Base or any other supported chain, to be able to exchange LSK, because I can’t send LSK tokens to Binance (most popular). The alternative it to go on a wild goose chase for a service that supports the token. If we can have it all in our choice wallet (metamask), it makes it even easier
