Adds the network with the exact values on this page (EIP-3085 wallet_addEthereumChain), then switches to it.
Trust Wallet
- Settings → Networks (or the network selector) → Add custom network.
- Choose an EVM network and enter the RPC URL, chain ID 9193, symbol tPIO and explorer URL from this page.
- Save, select the network, and copy your 0x address into the faucet.
Custom-network support differs between Trust Wallet versions and platforms. If your version does not offer it, use MetaMask or another EVM wallet.
