Frequently asked questions

Is it safe to add Memento Testnet (deprecated) 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 Memento Testnet (deprecated) Chain ID?▾
The Chain ID of Memento Testnet (deprecated) is 12052024. 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 Memento Testnet (deprecated)?▾
Yes. Every transaction on Memento Testnet (deprecated) requires ETH to pay gas fees. You can purchase ETH on exchanges and bridge it to Memento Testnet (deprecated), or use a faucet if this is a testnet.
What is the Memento Testnet (deprecated) RPC endpoint?▾
An RPC endpoint is the server address your wallet uses to communicate with the Memento Testnet (deprecated) blockchain — sending transactions, reading balances, and checking state. This page shows live latency for each RPC so you can pick the fastest one.
My wallet says Memento Testnet (deprecated) already exists when I click Add — what do I do?▾
That's completely normal. If Memento Testnet (deprecated) is already in your wallet, it will simply switch to that network instead of adding a duplicate — no error or conflict.
I added Memento Testnet (deprecated) 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.
