Ethers.js – Disabling Cache to Ensure Fresh Data

ethers.js

I want to disable cache when suing ethersjs v6. Did not find any documentation related to that. Is that possible?

Best Answer

In the provider options, you can pass a negative cacheTimeout which would disable caching (source).

const provider = new ethers.JsonRpcProvider(
  "https://rpc.url",
  undefined,
  {
    cacheTimeout: -1,
  }
);

You can initialize ethers and set a provider variable

const provider = new ethers.providers.Web3Provider(window.ethereum);

then you add/remove events by

const { provider: ethereum } = provider;
ethereum.on('accountsChanged', someFunction}; 
ethereum.off('accountsChanged', someFunction};

Ethers.js – Retrieving the Provider Object from a Wallet Object

If your wallet is connected to the provider you should be able to get the providers object using wallet.provider

if you are trying to access the send function of the provider try creating a provider with JsonRpcProvider like:

create a provider with new ethers. providers.JsonRpcProvider(<networkUrl>)
but I guess this send function is used to fetch blockchain with raw data

if you are trying to send transaction using ethers provider directly. use provider.sendTransaction(<signedTransaction>) this will send your signed Transaction to blockchain
