 Users post their cashu sat in the event, and the relay is the first to receive the event. The relay copies the cashu sat, then receives it, and then forwards the message.

 You can use free relay.

 I mean for the payment? does the relay define which cashu it accepts? 
or how can the relay know it's some valuable token?

 The relay decides which mints' issued ecash sat it will accept as stamps. 

A mint can set up a whitelist, and the relay will accept sats from mints on this list. 

If a user uses a new mint, the relay can first verify whether this sat can be redeemed for ln sat. If it can, the new mint will be added to the whitelist.

 ok, so there relay communicates the mint list upfront to the client.
