What is DataHopper?

DataHopper 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 DataHopper once you add the network configuration.

Why do you need to add DataHopper to your wallet?

MetaMask and most wallets only come pre-configured with Ethereum Mainnet. To transact, swap tokens, or use dApps on DataHopper, 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 DataHopper to your wallet

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 DataHopper network.
2
Confirm in your wallet
Your wallet shows the DataHopper network details: Chain ID 2021121117, native token HOP. Verify the Chain ID is correct, then click "Approve" or "Add Network".

Frequently asked questions

Is it safe to add DataHopper 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 DataHopper Chain ID?▾

The Chain ID of DataHopper is 2021121117. This unique number identifies the network and prevents MetaMask and other EVM wallets from mixing up transactions across different chains.

Do I need HOP tokens to use DataHopper?▾

Yes. Every transaction on DataHopper requires HOP to pay gas fees. You can purchase HOP on exchanges and bridge it to DataHopper, or use a faucet if this is a testnet.

What is the DataHopper RPC endpoint?▾

An RPC endpoint is the server address your wallet uses to communicate with the DataHopper blockchain — sending transactions, reading balances, and checking state. One popular DataHopper RPC is https://23.92.21.121:8545. This page shows live latency for each RPC so you can pick the fastest one.

My wallet says DataHopper already exists when I click Add — what do I do?▾

That's completely normal. If DataHopper is already in your wallet, it will simply switch to that network instead of adding a duplicate — no error or conflict.

I added DataHopper 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.
