live — RPC endpoint serving RPC endpoint testnetOur Ethereum Sepolia presence is the relay: a public JSON-RPC endpoint, free for baseline reads, with a flat $25/30-day key or a per-call x402 lane (USDC, no signup) for volume. Our Hoodi-side distributed-validator infra (SSV op 668 + a 3-node Charon cluster) is on the adjacent Hoodi testnet — see /validators/.
