How this works

You send N tokens to the echo dapp's address. A server-side process polls the chain, sees your transaction, and uses the sidecar's /wallet/send RPC to return N-1 tokens.

The wall-clock numbers above measure your phone's view of the round-trip; the server-side breakdown shows where the time is going (poll lag → RPC submit → chain confirmation).
