What is Cycle Network Testnet?

Cycle Network 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 Cycle Network Testnet once you add the network configuration.

Why do you need to add Cycle Network Testnet to your wallet?

MetaMask and most wallets only come pre-configured with Ethereum Mainnet. To transact, swap tokens, or use dApps on Cycle Network 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 Cycle Network 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 Cycle Network Testnet network.

  2. 2

    Confirm in your wallet

    Your wallet shows the Cycle Network Testnet network details: Chain ID 1221, native token ETH. Verify the Chain ID is correct, then click "Approve" or "Add Network".

  3. 3

    Switch to the new network

    After confirming, your wallet automatically switches to Cycle Network Testnet. You can start transacting right away — you will need ETH to pay gas fees.

Important notice

  • •Always verify Chain ID 1221 before confirming — attackers sometimes create fake networks with similar names but different Chain IDs
  • •You need ETH tokens in your wallet to pay gas fees for transactions on Cycle Network Testnet
  • •Data on this page is sourced from chainid.network — the community-verified Ethereum chain registry
  • •If the "Add to wallet" button doesn't work, your wallet may not support wallet_addEthereumChain — add the network manually using the details below

Frequently asked questions

Is it safe to add Cycle Network 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 Cycle Network Testnet Chain ID?▾
The Chain ID of Cycle Network Testnet is 1221. This unique number identifies the network and prevents MetaMask and other EVM wallets from mixing up transactions across different chains.
Do I need ETH tokens to use Cycle Network Testnet?▾
Yes. Every transaction on Cycle Network Testnet requires ETH to pay gas fees. You can purchase ETH on exchanges and bridge it to Cycle Network Testnet, or use a faucet if this is a testnet.
What is the Cycle Network Testnet RPC endpoint?▾
An RPC endpoint is the server address your wallet uses to communicate with the Cycle Network Testnet blockchain — sending transactions, reading balances, and checking state. One popular Cycle Network Testnet RPC is https://rpc-testnet.cyclenetwork.io. This page shows live latency for each RPC so you can pick the fastest one.
My wallet says Cycle Network Testnet already exists when I click Add — what do I do?▾
That's completely normal. If Cycle Network Testnet is already in your wallet, it will simply switch to that network instead of adding a duplicate — no error or conflict.
I added Cycle Network 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.
