What is Shardeum Testnet?

Shardeum Testnet is an EVM (Ethereum Virtual Machine) compatible blockchain network. Any EVM wallet — MetaMask, Rabby, OKX Wallet, Trust Wallet, Coinbase Wallet — can connect and transact on Shardeum Testnet once you add the network configuration.

Why do you need to add Shardeum Testnet to your wallet?

MetaMask and most wallets only come pre-configured with Ethereum Mainnet. To transact, swap tokens, or use dApps on Shardeum Testnet, you need to add the network first. Entering an incorrect Chain ID or RPC can put your assets at risk. Use the "Add to wallet" button above — data sourced directly from chainid.network, the canonical Ethereum chain registry.

How to add Shardeum Testnet to your wallet

  1. 1

    Click Add to wallet

    Press the "Add to wallet" button above. MetaMask, OKX Wallet, Rabby Wallet or Trust Wallet will show a popup asking you to confirm adding the Shardeum Testnet network.

  2. 2

    Confirm in your wallet

    Your wallet shows the Shardeum Testnet network details: Chain ID 8083, native token SHM. Verify the Chain ID is correct, then click "Approve" or "Add Network".

  3. 3

Frequently asked questions

Is it safe to add Shardeum Testnet to MetaMask?▾
Yes, if you use the "Add to wallet" button on this page. Data is sourced from chainid.network — the community-audited Ethereum registry. Adding a network does not expose your private key or grant any permissions to the dApp.
What is Shardeum Testnet Chain ID?▾
The Chain ID of Shardeum Testnet is 8083. This unique number identifies the network and prevents MetaMask and other EVM wallets from mixing up transactions across different chains.
Do I need SHM tokens to use Shardeum Testnet?▾
Yes. Every transaction on Shardeum Testnet requires SHM to pay gas fees. You can purchase SHM on exchanges and bridge it to Shardeum Testnet, or use a faucet if this is a testnet.
What is the Shardeum Testnet RPC endpoint?▾
An RPC endpoint is the server address your wallet uses to communicate with the Shardeum Testnet blockchain — sending transactions, reading balances, and checking state. One popular Shardeum Testnet RPC is https://api-testnet.shardeum.org/. This page shows live latency for each RPC so you can pick the fastest one.
My wallet says Shardeum Testnet already exists when I click Add — what do I do?▾
That's completely normal. If Shardeum Testnet is already in your wallet, it will simply switch to that network instead of adding a duplicate — no error or conflict.
I added Shardeum Testnet but the network won't load — what's wrong?▾
The most common cause is a broken or overloaded RPC endpoint. Your wallet uses RPC to connect to the blockchain — if the RPC is down, the network won't load even if it was added correctly. Fix: copy a different RPC from the list above (prefer green low-latency ones), then go to Settings → Networks in your wallet and replace the old RPC with the new one. Watch the tutorial video above for step-by-step instructions on updating your RPC.
