If a recurring charge fails, you'll receive an email explaining the reason. The two most common causes:
Insufficient balance in the connected wallet (Connect Wallet).
Allowance was revoked in the wallet, removing BoomFi's permission to charge.
What to do
Top up the wallet with the renewal amount plus a small buffer for gas.
If you revoked the allowance, sign in to your subscription via the Customer Portal and re-authorise it.
Retry the payment from the Customer Portal — most subscriptions allow a manual retry inside the same billing cycle.
If retries also fail, the subscription will eventually be marked as Past Due and access to the merchant's product may be suspended. In that case, you should contact the merchant.
Prevention tips
Do not revoke wallet allowances for active subscriptions. If you do not want to get charged for a new installment, you should cancel the subscription via your customer portal.
Consider keeping a small standing balance buffer in your subscription wallet.
If you switched wallets, set up a new subscription rather than expecting the old one to follow you.
