onyx_x402_demo_wallet
InactiveTool of onyx-paid-mcp
Dev-sandbox wallet helper for x402 testing. Generates a deterministic ephemeral Sepolia wallet (or accepts your address), reports ETH + USDC Sepolia balances, points to the Circle USDC Sepolia faucet, and emits a copy-paste env config for x402 client SDKs. SANDBOX ONLY — generated keys are deterministic and MUST NOT receive real value. (price: $0 USDC, tier: free)
