How to Install and Use Blocto Wallet on Flow (2026 Guide)

Blocto is a consumer wallet built by Portto. It began on Flow and later added support for other chains. It is a smart-contract style wallet: you sign in with an email address or phone number, and the app creates and manages the account for you. No seed phrase has to be written down at sign-up.

This works well on Flow because Flow accounts are not tied to a single private key. A Flow account can hold several keys, each with its own weight, and a transaction needs enough combined weight to be valid. Wallets like Blocto use this to split signing authority between your device or login and the wallet service. That is why recovery can be easier than with a standard seed-phrase wallet, and also why you should understand who holds which key.

What that means in practice:

• Flow addresses are short: 0x followed by 16 hexadecimal characters.
• Accounts need a storage balance. Flow requires a small amount of FLOW to cover account storage, and the wallet usually handles this when you create the account.
• Tokens need a vault. An account must have a token vault set up before it can receive a given fungible token or NFT collection.
• Fees are low. Flow transaction fees are small, and wallets may sponsor some of them.

The trade-off is that you rely on the wallet provider's infrastructure for part of the signing flow, which differs from a pure self-custody wallet. Treat that as a design choice to weigh, not a flaw to ignore. Read the app's current documentation to see exactly how keys are held before putting meaningful value in it.

Wallet products change. Apps get new features, drop chains or wind down. Before you install anything, spend two minutes confirming the basics.

Check these first:

1. Official source. Find the app through the official website of Portto or Blocto, or through the Apple App Store or Google Play listing that the site points to. Public reporting and social posts can lead to copycat apps.
2. Maintenance. Look at the store page for a recent update date and a believable developer name. An app that has not been updated for a long time is a warning sign.
3. Flow support. Check the app's supported network list or help pages to confirm Flow is still available and which Flow features, such as NFTs, work.
4. Your device. A phone with a current operating system and a screen lock is the safest base. If you plan to use the web wallet, use an up-to-date browser on a computer you trust.
5. A recovery plan. Have access to the email address or phone number you will register, because it is likely the key to recovering the account.

What you will need:

• A working email address or mobile number.
• A phone or computer you control.
• A small amount of FLOW to test with, if you want to try transfers.

If you cannot confirm Flow support or the app's current status from official sources, do not deposit funds. Use a different Flow wallet instead. Several others exist, including Flow Wallet and the Dapper wallet used for some NFT platforms.

Blocto has been offered as a mobile app for iOS and Android and as a web wallet in the browser. The steps are similar.

Mobile install

1. Open the App Store or Google Play and search for Blocto, or follow the store link from the official site.
2. Confirm the developer name matches the official publisher and that the icon and description match the official site.
3. Tap Install, then open the app.
4. Accept the permissions the app needs. Be cautious about any request that seems unrelated to wallet use.
5. Turn on a device passcode or biometric lock if you have not already.

Web wallet

1. Type the official address into your browser yourself, or use a bookmark you trust. Do not click ads or public reporting that promise a wallet.
2. Sign in with the same method you use on mobile, so both point to the same account.
3. Bookmark the page so you can return safely later.

Good habits at this stage:

• Never install a wallet from a link sent in a message, even from someone you know.
• Never download an APK from an unofficial site.
• Do not enter any recovery information into a page you reached through a pop-up.

Once the app opens, you should see a sign-up or login screen. A genuine wallet app will never ask for a seed phrase or private key from another wallet just to open.

After installation, creating a Flow account takes a few minutes.

1. Choose a sign-up method. Pick email or phone number, whichever is offered. Use a mailbox or number you will keep long term.
2. Verify. Enter the one-time code that arrives. Codes expire, so enter it promptly.
3. Set a security method. The app may ask for a password, PIN or biometric unlock. Choose a unique password that you do not reuse elsewhere.
4. Let the account be created. Blocto sets up the account on supported chains, including Flow. On Flow, this creates an address starting with 0x and registers the keys for that account.
5. Find your Flow address. Open the Flow asset or network view and use the receive or copy option. Compare the first and last characters of the copied address with what you see on screen.
6. Check the account on an explorer. Paste the address into a Flow block explorer to confirm it exists and view its keys and balance.

If the app offers several networks, make sure you are on Flow before you copy an address. An address from another chain will not work for Flow assets.

Tip: Send a very small test amount first, wait for it to arrive, and only then move larger amounts. A test transfer costs little and tells you that the address, network and token are all correct.

Because Blocto does not rely on a standard seed phrase, protecting the login is the main task. Anyone who can pass the sign-in checks can potentially reach the account.

Lock down the login

• Use a strong, unique password and a password manager.
• Turn on two-factor authentication on the email account, preferably with an authenticator app or hardware key and not SMS alone.
• If phone number sign-in is used, protect the SIM with a carrier PIN, because SIM-swap attacks target accounts tied to numbers.

Understand recovery

• Read the app's help pages to learn what happens if you lose the phone, change numbers or lose email access.
• Note whether the app offers a way to export or add keys, and what the custody trade-offs are.
• Keep a written note of which email or number the account uses, stored somewhere safe and offline.

Device hygiene

• Keep the operating system and app updated.
• Use a screen lock and avoid installing apps from outside official stores.
• Do not log into the wallet on shared or public computers.

Limit exposure

Treat the wallet like a spending account. Keep larger holdings in a setup you have fully verified and understand, such as a hardware wallet that supports Flow, and move only what you need for apps. Never share verification codes with anyone claiming to be support. Genuine support will not ask for them.

To receive FLOW, share your Flow address and make sure the sender uses the Flow network.

Receiving FLOW

1. Open Blocto and select the Flow network or the FLOW token.
2. Choose Receive, then copy the address or show the QR code.
3. Give it to the sender. If you are withdrawing from an exchange, select Flow as the withdrawal network.
4. Confirm the first and last characters on the exchange screen before you submit.

Receiving other tokens and NFTs

On Flow, an account can only hold a fungible token or NFT collection after it has a matching vault or collection set up. Blocto usually shows a prompt to enable or add a token. Some apps do this automatically in the background when you first interact with them. If a token does not appear:

• Look for an add token, enable or manage assets option.
• Confirm the sender used the correct token and network.
• Check the transaction on a Flow block explorer using its transaction ID.

Do not send across networks

Flow addresses are 16 hexadecimal characters after 0x. Ethereum-style addresses are 40 characters. Sending between the two networks directly can cause permanent loss. Flow also has an EVM environment with Ethereum-style addresses, so check which environment a destination is on before sending.

If an exchange does not list Flow as a network, do not try a workaround. Pick a different route or a bridge.

Sending is straightforward once the address and network are right.

1. Open Blocto and pick the Flow network and the token you want to send.
2. Tap Send and paste or scan the recipient's address. Flow addresses start with 0x.
3. Check the address carefully. Compare the beginning and end, because clipboard-replacing malware can swap an address after you copy it.
4. Enter the amount. If you are sending the full balance of FLOW, leave enough behind to cover the account's storage requirement.
5. Review the confirmation screen, including any fee. On Flow the fee is typically small, and Blocto may cover some of it.
6. Approve the transaction using your security method.
7. Wait for the status to show as sealed or confirmed, then check the transaction on a Flow block explorer.

Sending NFTs

The recipient's account must have the right collection set up. If it does not, the transfer fails. Ask the recipient to enable the collection first, or use a marketplace that handles setup.

Good practice

• Send a small test amount before a large transfer.
• Save the recipient address in a contact list only after verifying it independently.
• Never rush because someone is pressuring you to send funds. Urgency is a common sign of a scam.

Flow transactions normally finalize quickly. If one stays pending, do not resend straight away. Check the explorer first so you do not send twice.

Blocto can connect to apps that support it, typically through an in-app browser, a connect-wallet prompt or a QR code.

A typical connection

1. Open the app or marketplace you want to use.
2. Choose Connect Wallet and select Blocto from the list. Not every Flow app lists it, so check the app's supported wallets.
3. A Blocto window or mobile prompt opens. Check that the site name and requested permissions look right.
4. Approve the connection. This normally only shares your public address and lets the site request transactions.
5. When the app asks you to sign a transaction, read the details on the Blocto approval screen before confirming.

What to look for in a signing request

• Which assets are moving, and in which direction.
• Whether the transaction sets up a vault or collection, which is normal, or does something unexpected.
• Whether the site and the request match. A mismatch between what you wanted and what is shown is a reason to cancel.

Managing permissions

A wallet connection is not an unlimited approval, but you should still disconnect from sites you no longer use. Look for a connected apps or sessions list in the settings.

Avoid phishing

Bookmark the apps you use. Fake sites copy real ones and ask you to connect and sign. Never sign a transaction you do not understand, and never enter login details on a page that you reached from an unsolicited message.

Assets on other chains cannot be sent to a Flow address directly. They have to cross a bridge, which locks or burns tokens on one chain and issues them on another. Bridges are a common source of losses, so treat them carefully.

Basics

• Confirm that a route exists for the exact token, source chain and Flow environment you need. Flow has its own native environment as well as an EVM environment, and bridges may support only one.
• Use bridges with a track record, and read how they work. Some are canonical bridges run by a chain's own team; others are third-party protocols.
• Check the bridge's current status and supported chains on its official site, because routes open and close.

Process

1. Start with a small test amount.
2. Select the source chain, destination chain and token.
3. Paste the destination address and check it character by character.
4. Review fees and estimated time, then approve.
5. Track the transfer on the bridge's status page and a block explorer.

Bridges to research

The cross-chain protocols covered on this site include cBridge, LayerZero V2, Across, Stargate V2 and Hyperlane. Whether any of them supports a Flow route changes over time, so check each one's supported-chain list before planning a transfer.

If a simpler path exists, such as withdrawing FLOW directly from an exchange that lists Flow, that is usually safer than bridging.

A few problems come up often. Most are fixable.

Balance or token not showing

• Refresh the app and confirm you are on the Flow network.
• Check the transaction on a Flow block explorer. If it succeeded, the funds are on the account.
• Look for an option to add or enable the token.

Transaction fails

• Make sure you have enough FLOW for storage and any fees.
• For NFTs, confirm the recipient has set up the collection.
• Retry only after checking that the first attempt did not go through.

Cannot log in

• Check that you are using the same email or number as at sign-up.
• Look in spam folders for verification codes.
• Update the app, or try the web wallet.
• Use the official help channels to recover, and never share codes with anyone who contacts you first.

Wallet app unavailable or no longer supports Flow

Check the official announcements and store listing. If the service is being wound down, move your assets to another Flow wallet well before any cutoff, and verify the process in official documentation first.

Warning signs of a scam

• Direct messages offering support.
• Requests for verification codes, passwords or recovery details.
• Websites asking you to connect and sign after clicking an ad.

Crypto transfers are generally irreversible, so slow down at each step.
