It seems that a recent change to switch from
ethjs-query
to Ethers has caused a regression: when the network is switched,this.web3
still points to the previous network. This happens because Web3Provider saves a copy of thesendAsync
method on the given provider, so even ifnonce-tracker
is given a provider proxy,this.web3
still has a reference to thesendAsync
method from the previous provider object.This is a common problem with Ethers. Although Ethers has some nice features, we don't need to pull it in here, and we can use
@metamask/eth-query
(which provides TypeScript support, unlike@metamask/ethjs-query
) instead. We do lose one feature of Ethers, which is that it automatically converts response data for requests to the appropriate types, but we can make use of@metamask/utils
to help with this.Fixes #58.
