# `gno.land/r/moul/x/daily/ratelimitdemo/v0`
Live demo of the [`p/moul/x/daily/ratelimit`](https://github.com/moul/gno-contracts/tree/main/p/moul/x/daily/ratelimit/v0)
token-bucket rate limiter.
Holds one package-level `ratelimit.Limiter` (0.5 tokens/block, capacity 5) and
wires it to the chain — the tick is `runtime.ChainHeight()`, each caller is keyed
by `unsafe.PreviousRealm().Address()`:
- `Allow(cur) bool` — consume one token for the caller.
- `SetConfig(cur, rate, burst)` — retune the shared bucket.
- `Tokens(addr) int` — read-only balance.
- `Render("/")` — config + a table of callers; `Render("/addr/<address>")` focuses one.
All refill/consume math lives in the library; this realm is just the wiring and
the gnoweb view. Render it at [`/r/moul/x/daily/ratelimitdemo/v0`](https://gno.land/r/moul/x/daily/ratelimitdemo/v0).
