Frequently Asked Questions

Everything you need to know before you start. Plain language, no jargon.

You lose everything — contacts, messages, and funds. Permanently and irreversibly. This is how every non-custodial wallet works: no company holds a copy of your keys, so no one can recover them for you.

However, Echo Protocol offers something no other similar app provides: you can designate a digital heir. Any trusted person who also has the Echo app installed can be set as a recipient of a timed message containing your seed phrase, your access instructions, or anything else you want to pass on.

Set a timer. As long as you keep sending the heartbeat signal, the message stays sealed. If you ever lose access — the message reaches your chosen person automatically. It's a safety net that no other non-custodial wallet offers.

Every message sent through Echo Protocol is a micro-transaction on the Secret Network blockchain. This means a small network fee applies each time — just like any on-chain operation.

You need a small amount of SCRT (the Secret Network token) in your wallet to pay these fees. The good news: the cost is minimal.

Whisper messages: approximately 2,000 messages per $1 USD (as of April 2026).
A few cents in SCRT is enough to get started.
⚠️ Digital inheritance switches have higher fees: 6 SCRT for short test timers (under 1 hour), and 12 SCRT each time you set a timer longer than 1 hour.

You can acquire SCRT on any major exchange or directly within the app using the built-in swap feature.

By design. Echo Protocol never accesses your phone's address book — doing so would require us to read your personal contacts, which contradicts the app's core privacy principles.

Other messaging apps can match contacts because they run central servers that cross-reference phone numbers. Echo has no central server — it uses the Secret Network blockchain as its backbone instead.

To add a contact, tap the Inner Circle button and enter their wallet address directly. It takes a few seconds, and once added, the contact is yours — no server involved, no data shared.

By default, contacts are saved in your phone's local storage. They never leave your device unless you explicitly choose to back them up.

If you're switching phones or want a permanent backup, Echo Protocol lets you save any contact directly to the blockchain. Each time you add a new contact, the app asks whether you'd like to save it on-chain — just tap OK.

On-chain contacts survive phone changes, app reinstalls, and any local storage loss. They are tied to your wallet address, not your device.

Nothing breaks. Echo Protocol is completely serverless: messages and inheritance switches live on a permanent smart contract on the Secret Network blockchain. No server to shut down, no company to go bankrupt, no subscription to cancel.

The only feature that requires a server is the notification that tells you a new message has arrived — just that single alert, nothing else. If the server ever disappeared, you would still send and receive messages normally; you just wouldn't get the push notification while the app is closed.

Every critical operation — sending a message, setting an inheritance switch, resetting a timer — is signed locally on your device and written directly to the blockchain. No middleman involved.

A Sealed Message is what you see when someone has set you as the recipient of a digital inheritance switch. It appears in your Whispers screen with a padlock icon and a live countdown.

The message is already on the blockchain, already encrypted for your eyes only — but locked until the timer runs out. As long as the sender keeps sending the heartbeat signal, the countdown resets and the message stays sealed.

When the timer reaches zero — because the sender chose not to reset it, or simply couldn't — the message unlocks automatically and reveals its content. Only you can read it.
