Proxy Chaining

Protocol nesting (wrap one protocol in another):

client_chain:
  address: "proxy.example.com:443"
  protocol:
    type: tls
    protocol:
      type: vmess
      cipher: aes-128-gcm
      user_id: "uuid"

Multi-hop chains (route through multiple proxies sequentially):

client_chain:
  chain:
    - address: "proxy1.example.com:1080"
      protocol:
        type: socks
    - address: "proxy2.example.com:443"
      protocol:
        type: tls
        protocol:
          type: vless
          user_id: "uuid"

For client_chains, group references, and pool: hops, see routing rules. Define named groups under client proxy groups; see the controller and selectors page for selector and url-test selection.
