Frequently asked questions

Is it safe to add Thinkium Testnet Chain 103 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 Thinkium Testnet Chain 103 Chain ID?▾
The Chain ID of Thinkium Testnet Chain 103 is 60103. This unique number identifies the network and prevents MetaMask and other EVM wallets from mixing up transactions across different chains.
Do I need TKM tokens to use Thinkium Testnet Chain 103?▾
Yes. Every transaction on Thinkium Testnet Chain 103 requires TKM to pay gas fees. You can purchase TKM on exchanges and bridge it to Thinkium Testnet Chain 103, or use a faucet if this is a testnet.
What is the Thinkium Testnet Chain 103 RPC endpoint?▾
An RPC endpoint is the server address your wallet uses to communicate with the Thinkium Testnet Chain 103 blockchain — sending transactions, reading balances, and checking state. One popular Thinkium Testnet Chain 103 RPC is https://test103.thinkiumrpc.net/. This page shows live latency for each RPC so you can pick the fastest one.
My wallet says Thinkium Testnet Chain 103 already exists when I click Add — what do I do?▾
That's completely normal. If Thinkium Testnet Chain 103 is already in your wallet, it will simply switch to that network instead of adding a duplicate — no error or conflict.
I added Thinkium Testnet Chain 103 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.
