Cancel subscription

With sub2-sdk you can directly cancel a subscription by providing its index:

const transactionReceipt: TransactionReceipt = await sub2SDK.cancelSubscription(index);

The cancellation will only go through if the account in the provided walletClient is either the subscriber or the recipient. The returned value of viem type TransactionReceipt gives information about the transaction.

Note: This performs an on-chain transaction and requires that the sub2SDK object was initialised with a walletClient.
