Integration Instructions
Or how to integrate SubWallet and other Polkadot and Kusama wallets into your DApps
SubWallet, Polkadot{.js} and Talisman extensions allow DApp to connect with them by publicizing their interaction in object
injectedWeb3
of window browser.- SubWallet (public with properties
subwallet-js
) - Polkadot{.js} (public with properties
polkadot-js
) - Talisman (public with properties
talisman
)

You can open
injectedWeb3
object in Chrome devtools.
Please refer to our examples below:
- Check extension's activation:
- When a wallet extension is active in browser it will modify
window.injectedWeb3
by adding its interaction with a specific name. - For example, check SubWallet extension by these code:
window.injectedWeb3 && window.injectedWeb3['subwallet-js']
- Enable intergation into your DApp by method
enable()
of extension interaction object.const SubWalletExtension = window.injectedWeb3['subwallet-js']const extension = await SubWalletExtension.enable()- After running, these code extension will show popup confirmation to confirm integration into your DApp
- After enabling,
extension
variable can contain these objects:accounts
: Allow getting accounts' data with 2 methods,get
andsubscribe
.signer
: Allow signing data with 2 methods,signPayload
andsignRaw
.metadata
: Allow getting additional metadata list with methodget
and adding/updating with methodprovide
.
If your DApp is writen in typescript, you need to add package
@polkadot/extension-inject
to your package.json to get extensions interfaces.Last modified 8mo ago
