Configure QUIC transport

QUIC is a UDP-based transport. Enabling it allows peers to connect to your node over QUIC, in addition to the default TCP transport.

To enable QUIC, use the --quic-support option. Note, the default port for QUIC is 60000.

wakunode2 --quic-support=true

To listen on a different UDP port, use --quic-port:

wakunode2 --quic-support=true --quic-port=<port>

QUIC runs alongside the existing TCP transport. The node keeps listening on TCP and announces a /udp/<port>/quic-v1 address in its ENR, so peers that support QUIC can connect over it while others continue to use TCP.

If you restrict the node's announced addresses with --ext-multiaddr-only, the QUIC address is no longer announced automatically. In that case, include the QUIC multiaddr in --ext-multiaddr yourself, for example /ip4/<ip>/udp/<port>/quic-v1.
