Networks
Custom RPC
Each network reads and broadcasts through an RPC endpoint. You can set that URL. This site does not publish a vendor catalog.
An RPC endpoint is how the wallet reads chain state (balances, nonce, receipts) and broadcasts signed transactions. GreyWallet lets you configure the RPC URL per network. GreyWallet does not list Infura, Alchemy, or any other provider here. Use an endpoint you operate or a provider you have independently verified.
A malicious or misconfigured RPC can return false balances, omit transactions, serve the wrong chain, or observe your addresses. Treat RPC as trust configuration.
Configure
01
Select the network
An Ethereum URL will not serve Solana. An L2 URL is not Ethereum mainnet. Chain ID must match the network you think you are on.
02
Enter a URL you trust
HTTPS from infrastructure you control, or a provider whose terms you accept. Do not paste URLs from chat, email, or a support impersonator.
03
Verify before you send
Check chain ID, a known address’s balance, and recent activity against a second source.
GreyWallet does not custody your RPC API keys and does not guarantee third-party uptime. If an endpoint fails, change it. Support cannot see which RPC you configured.
