Your first step into Shardeum begins with setting up a self-custodial wallet (also known as a non-custodial wallet). This isn’t just about installing a wallet app — it’s about creating a self-sovereign identity that gives you full control over your funds and data on the Shardeum blockchain and across the wider Web3 ecosystem.
Take control of your digital and financial future — on your terms.
To make sense of how self-custodial wallets work, it helps to compare them to something more familiar — like digital payment apps such as Google Pay.
A Shardeum account is your identity on Shardeum blockchain. It’s made up of two cryptographic keys — a public key (used to create and share your “wallet address”) and a private key (used to access and control your account).
Your wallet securely stores your private key, while your actual account data — like your SHM balance and transaction history — is stored on the blockchain network.
When you use your wallet to sign a transaction, it uses your private key to prove that it’s really you — without ever revealing the key itself.
Getting started with Shardeum is simple — it only takes two main steps to set up your wallet and connect to the network:
For this tutorial, we’ll use MetaMask — a popular, user-friendly Web3 wallet available as a browser extension (we’ll be using Chrome) and as a mobile app. The process is more or less the same if you want to use another wallet provider. Just make sure they are EVM-compatible, which we will talk about in a bit.
Go to https://metamask.io on your browser and click on “Get MetaMask”
Add it to your Chrome browser by clicking “Add to Chrome” and approving permissions.
Once installed, you can now access MetaMask by clicking the puzzle-shaped Extensions icon in your browser toolbar and selecting the MetaMask icon.
Open MetaMask from your browser’s extension menu and click on “Create a new wallet”.
Agree to the terms, then create a strong password (minimum 8 characters). This password is used only to login to MetaMask wallet locally on your device. Note, you cannot recover the MetaMask login password itself — but you can reset it using your Secret Recovery Phrase (SRP), which we will cover right below. Aftering creating your MetaMask password, click on “Create a new wallet” again.
On the next screen, you’ll be prompted to secure your wallet using a Secret Recovery Phrase (SRP) — a unique 12-word phrase. Choose “Secure my wallet (recommended)” to proceed and follow the instructions. This phrase is the only way to recover your wallet if you ever lose access, so make sure to store it safely and offline.
After clicking Next, you’ll be asked to confirm your SRP by selecting the words in the exact order they were shown. Once confirmed, MetaMask will display a message indicating that your wallet is ready to use. It will also remind you where to find your recovery phrase later, in case you need to back it up again in the future.
You can click “Done”. The next screen will confirm that MetaMask has been successfully installed and guide you on how to pin the MetaMask extension to your browser toolbar for easy access.
You’ll now land on the MetaMask home screen — the same screen you’d see if you opened MetaMask from your browser’s extension toolbar or your mobile app. Your first wallet account will be typically labeled “Account 1,” with a default balance of 0 ETH. Below that, you may see 0 USD, which simply reflects the current value of your ETH (or other EVM based tokens) in USD. You can customize this display or switch currencies anytime in the settings later.
0x Wallet Address → A string of characters starting with 0x3bD..52.This is your public-facing address. You can copy it by clicking on it — use this to receive SHM tokens and connect to available applications.| Element | What It Does | Visibility |
|---|---|---|
| Public Key | Generates your wallet address; used to verify transactions | Hidden |
| Wallet Address | Derived from your public key; share this to send and receive tokens | Visible |
| Private Key | Used to sign transactions; proves you are the owner | Hidden, exportable |
| Recovery Phrase (Seed Phrase) | A master key that can regenerate all accounts in your wallet | Shown once during setup |
MetaMask is an Ethereum Virtual Machine (EVM) compatible wallet, which means it’s connected to the Ethereum Mainnet by default. However, it’s important to note that Ethereum and Shardeum are two entirely separate Layer 1 blockchains.
As highlighted in Shardeum’s whitepaper, our strategy is to innovate at the core — scalability and decentralization — while deliberately retaining familiar elements like wallet compatibility, the EVM, and blockchain explorers. This ensures a seamless experience and faster adoption for both users and developers.
Now let’s add the Shardeum network. Click the network dropdown at the top of MetaMask and select “Add a custom network”.
Next, input the Shardeum RPC endpoint, which serves as a technical bridge (or API) allowing your wallet to interact with the Shardeum network. Currently, you can connect to the Shardeum Testnet using the following details and hit Save
Once you’ve added the network, clicking the network dropdown will now display both Ethereum Mainnet and Shardeum Testnet. Select “Shardeum Testnet”, and your wallet interface will switch — allowing you to see the difference immediately.
The Shardeum Mainnet RPC endpoint will be released closer to the mainnet launch date. Once available, you can add it similarly as shown above.
When you switch from Ethereum to Shardeum in your MetaMask wallet, you’ll notice something interesting:
🔄 What Changes:
✅ What Stays the Same:
Shardeum Wallet Address:
1. This is the address you’ll use to send and receive SHM, sign transactions, check your balance, and connect to other applications on the network.
2. Whether you're using Shardeum Testnet or Mainnet, your wallet address stays the same. Just switch networks to view the corresponding balance and transactions.
L1 blockchain networks like Shardeum majorly runs two types of networks: Testnet and Mainnet.
The Testnet is a safe, sandbox environment — often rolled out in multiple stages or phases — where users and developers can explore features incrementally, test transactions, and build applications using test SHM tokens that hold no real-world value.
The Mainnet, on the other hand, is the live version of the blockchain where real SHM tokens are used and all transactions are permanent.
Installed directly in your web browser (e.g., Chrome, Firefox), these wallets are ideal for interacting with dApps and signing transactions on desktop. Example: MetaMask
Designed for smartphones, mobile wallets let you send, receive, and manage crypto easily on the go. They also support features like QR scanning and in-app browsers for dApps. Examples: MetaMask Mobile, Trust Wallet
Physical devices that store your private keys offline, offering the highest level of protection against online threats and hacks. Ideal for long-term or high-value storage. Examples: Ledger, Trezor
Accessible directly through a browser without installing extensions, web wallets offer convenience but may rely on third-party infrastructure. Example: Rabby
We’ll publish a full list of supported wallets closer to Shardeum’s Mainnet launch. In general, most EVM-compatible wallets will work seamlessly.
When you create a wallet, you’ll be shown a Secret Recovery Phrase (also called a seed phrase) — typically 12 randomly generated words. This phrase generates your wallet’s private key and is the only way to recover your wallet if you lose access to your device or forget your local password.
Treat it like your master key and never share it with anyone — not even with people claiming to be support staff. We strongly recommend writing it down and storing it in a secure, offline location. If someone gains access to your seed phrase, they can generate your private key, gain full control of your wallet, and transfer all your funds to their own address — and there’s no way to reverse it.
On centralized exchanges, your wallet is tied to a username and password — not cryptographic keys. If you lose access, recovery is often possible through traditional methods like KYC verification or customer support. In some cases, they may even help reverse or retrieve funds sent in error.
In decentralized networks like Shardeum, your wallet is controlled entirely by you, secured through cryptographic keys, rather than a central authority. While this means you’re fully in charge of your wallet and transactions, it also means you are solely responsible for keeping your private key or recovery phrase safe.
Always double-check the network before sending or receiving SHM or any other tokens. Sending funds to or from a non-EVM-compatible network can result in permanent loss of assets, as those networks use different address formats and transaction protocols. Since wallets don’t usually warn you about mismatched networks, it’s important to manually verify that both sender and receiver are using EVM-compatible chains like Shardeum, Ethereum, or other supported networks.
While Shardeum focuses on building a robust and scalable base layer to make decentralization truly affordable and accessible, UX-focused innovations and interoperability in Web3 — along with evolving regulations worldwide — are steadily catching up, bringing a seamless Web3 experience closer to reality.
Now that your wallet is set up and connected to the Shardeum network, you can start using it for a range of activities — from signing transactions and viewing balances and transaction history to transferring SHM peer-to-peer (P2P).
Information on how to purchase SHM from public exchanges will be shared closer to the mainnet launch.
