Hedera Wallet Snap connects to your currently connected Metamask account by default. To learn how apps can connect to Hedera Wallet Snap using a non-metamask(external) account, refer to this documentation.
Then, depending on whether you're trying to connect to a metamask account or a non-metamask account, you can call the snap API in the following way:
constsnapId=`npm:@hashgraph/hedera-wallet-snap`constunstakeHbarAPI=async () => {constexternalAccountParams= { externalAccount: { accountIdOrEvmAddress:'0.0.12345', curve:'ED25519' } }awaitwindow.ethereum.request({ method:'wallet_invokeSnap', params: { snapId, request: { method:'unstakeHbar', params: { network:'testnet', nodeId:0/* Uncomment the below line if you want to connect to a non-metamask account */// ...externalAccountParams } } } })}
To learn about what it means to stake to a node vs an account, please refer to Staking Info Documentation.
What the API does
Retrieves the currently connected account the user has selected on Metamask. If it's the first time, a new snap account is created and the account info is saved in snap state.
Calls the Hedera SDK Update Account API to change the property related to staking which means it will also update setDeclineStakingReward to true hence, the account will stop receiving staking rewards
Some things to keep in mind while interacting with the above demo
If you're getting any errors with the live demo, make sure you go through the FAQs section to learn about what you may be missing. You need to install Metamask in your browser for the live demo to work
