Run the bootstrap

python3 web/evm/evm_rpc_bridge.py
# listens on 127.0.0.1:9545 and reads 127.0.0.1:8545
# refuses 0.0.0.0; send stays disabled

Add-to-MetaMask values (loopback only):

MetaMask/Trust/Binance cannot list this chain as-is. The helper below only talks to 127.0.0.1:9545 and does not enable send.

Button stays disabled until http://127.0.0.1:9545 answers chain 424242.

Live bootstrap probe

Calls http://127.0.0.1:9545 from this browser. If the bridge is not running, the panel stays RPC offline.
