# Use Signal

Understand a token's rules, what a trade costs and what flows back, before you launch or trade.

**Start**

- [Get started](get-started.md): sign in, your wallet, your first trade.
- [Your wallet](wallet.md): add money, send, back up, instant trading.

**Trade**

- [Trade a token](trading.md): the ticket, the cost line, slippage, the warnings.
- [Token safety](safety.md): what Signal checks and what the words mean.
- [Other chains and Swap](chains-and-swap.md): coins on Solana, Ethereum, BNB and Robinhood Chain.
- [The Desk and Classic](desk.md): the two layouts of the site.

**Launch**

- [Launch a token](launching.md): three fields and a button.
- [Signal v4 launches](signal-v4.md): every rule a launch can fix, and what can change afterwards.
- [Pairing assets and venues](pairing-assets.md) and [fees](fees.md).

**What flows back**

- [Signals and the leaderboard](signals.md).
- [Rewards, referrals and relief](rewards.md).
- [Echo](echo.md): Your Echo and Protocol Echo.
- [Spot rewards](spot-rewards.md) and [perp rewards](perp-rewards.md) on earlier launches.
