eth provider failed on mobile

[dckc]

I tried trust wallet. A colleague tried metamask.

I wonder if this we're using the current API or whatever.

rnode-client-js/src/eth/eth-wrapper.js

Line 1 in e4d97ee

// Metamask wrapper for Ethereum provider

I was using latest documentation for Metamask.
https://metamask.github.io/metamask-docs/guide/ethereum-provider.html#methods-new-api

Request for signature is in Ethereum format defined in EIP-1193.
https://eips.ethereum.org/EIPS/eip-1193

I'm not aware how browser extensions like Metamask can be run on mobile. I'm especially interested in using WebAuthn to connect directly from a web page.

The MetaMask extension provider is synchronously injected, while the MetaMask mobile provider is asynchronously injected. -- @metamask/detect-provider - npm

suggested fix for this and #15 : https://github.com/rchain-community/rchain-api/blob/master/src/ethProvider.js#L4-L59
