Benefits of Using a Temporary Phone Number for Alchemy
Alchemy is the leading platform for blockchain developers, providing the infrastructure and tools needed to build and scale decentralized applications (dApps). Signing up for an Alchemy account to get your API keys requires verification, often with a phone number. For a developer working on high-value projects, securing every layer of the development stack is critical. A virtual phone number is an essential security measure for any web3 builder.
Secure Your Developer Account and API Keys
Your Alchemy account holds the API keys that are the lifeblood of your dApp. A compromised account could be catastrophic. Using a dedicated virtual number—one that isn't publicly known or tied to other services—makes your account significantly more secure. It protects against SIM swap attacks and other phone-based vectors that hackers might use to try and gain access to your valuable developer assets.
Isolate Your Web3 Projects
As a developer, you understand the importance of sandboxing. A virtual number allows you to apply this principle to your identity. It isolates your professional Web3 activities on Alchemy from your personal life. A security issue on a personal social media account will have no bearing on the security of your Alchemy account, because they are not linked by the same phone number.
Manage Project Notifications Effectively
Using a virtual number allows you to create a dedicated channel for all notifications related to your blockchain projects. You can funnel alerts from Alchemy, server monitoring, and other dev tools to this number. This keeps you organized and ensures that critical alerts about your dApp's performance don't get lost in a sea of personal text messages, helping you stay responsive and in control.
Frequently Asked Questions
Yes, our numbers are specifically designed for Alchemy registration. Alchemy requires a phone number for account creation, and our virtual numbers provide a reliable way to receive the SMS verification code.
Yes, you can. SMSFAST allows you to rent multiple virtual numbers, meaning you can use a unique number for each Alchemy account.
First, double-check that you've copied the SMS code precisely as it appeared in your SMSFAST account and entered it correctly into Alchemy. Also, ensure the number you used is still active and within its valid time frame.
If the issue persists, the number might have been flagged by Alchemy. In such cases, we recommend simply renting a new temporary phone number and repeating the registration process.
There may be a slight delay in network delivery at times. Please give it a minute or two.
- Request resend: On the Alchemy interface, look for the option to resend the code. This often prompts a new SMS message to be sent to your number.
- Ensure you are actively viewing the SMSFAST interface for the specific virtual number you rented, as the SMS message will appear there.
If the code still doesn't arrive after a resend attempt, the temporary number might be experiencing an issue with that specific service. We recommend canceling the current number (if no SMS has been received, you typically won't be charged) and renting a new disposable number from SMSFAST.
A number is valid for up to 20 minutes for SMS verification purposes. This ensures you have enough time to receive your verification code and complete the registration.
Yes, we provide real, non-VoIP numbers from local SIM cards. You can use to register on a variety of services.
