blocto-sdk's Issues

Authentication feature for multiple account same device login

I am currently allowing users to log in/signup by using the fcl API to interact with blocto.

Assume we have users A and B who both use the same device.

User A logs into his account to do some transactions then logs out and leaves the device. User B then tries to log in but when he presses the login button, they see the following.

So now User B can either press confirm and log into user's A account or click the "use Another Account" button to log into his account.

What is mentioned above is very inconvenient especially if a user has multiple accounts and wants to perform transactions on one account but presses "confirm" by mistake and accidentally performs the transactions on a different account.

What I am asking is if there is a way to the following whenever a user presses the login button

Also, if there is already a workaround solution, could someone please guide me on how to overcome this issue?

Error: An interface property cannot have an initializer

The published TypeScript definitions seem to contain an error:

../../../node_modules/@blocto/sdk/dist/blocto-sdk.d.ts:17:25 - error TS1246: An interface property cannot have an initializer.

17   code: string | null = null;

This is using "@blocto/sdk": "^0.2.20".

setting RPC urls when initializing

When creating a bloctoSDK instance, would it be possible to pass all RPC and chains we want to potentially use? to avoid using wallet_addEthereumChain on the flow? I'm not sure if this makes sense, I'm currently exploring Blocto wallet.

I mean something like this

import BloctoSDK from '@blocto/sdk'

const bloctoSDK = new BloctoSDK({
    ethereum: {
       1: 'https://mainnet.infura.io/v3/YOUR_INFURA_ID',
       5: 'https://rpc.ankr.com/eth_goerli',
    },
    
    // (optional) Blocto app ID
    appId: 'YOUR_BLOCTO_APP_ID',
});

Thanks

Use different session keys for different environments

The issue

Currently the login session preservation uses the same key in LocalStorage, across different environments (mainnet vs. testnet)
https://github.com/portto/blocto-sdk/blob/30635a0fbad005c36c4d56e9d3fd7582b9f5632f/src/providers/blocto.ts#L18

For developers that are testing the same site domain (i.e. localhost:3000) and is switching between networks, the login session may be mixed up and cause troubles

Possible solution

Use different LocalStorage keys across different networks

Request: Temporary accounts on Testnet

I'm integrating Flow/FCL with Blocto. Testing new user flow is a pain because my email is already tied to a wallet, and blocto too clever to allow [email protected].

A testnet only feature to have temporary/ephemeral wallets would be appreciated.

Remove addSelfRemovableHandler

It can actually be replaced by adding once option in addEventListener

test.html not working

I followed install instructions but

https://localhost:7777/test.html returns a 404

Window is not defined error - NextJS

Due to the local storage code using window at the top level without checking if it exists, server side static renders on NextJS are failing.
