Getting Polygon's Mumbai test network history

[chitalian]

Hello,

I was wondering what is the equivalent of getting transaction history for maticmum?

Ideally I would love if I could do something like

const provider = new ethers.providers.AlchemyProvider("maticmum");
const history = await provider.getHistory(wallet.address);

But it seems getHistory is only supported for EtherscanProvider

Geth node doesn't have an efficient way to retrieve all the transactions of an account and so there isn't an rpc method implemented by the nodes, hence it's not trivial for ethers to include a getHistory for json rpc providers. It's possible for etherscan because they have the transactions indexed by wallet address in a database and they expose an API endpoint for the same.
