Basics

The tokens

SOUL, KCAL, RA and TAZ, and what each one is for here.

In shortFour tokens do most of the work: SOUL pays the data fee, KCAL pays gas, RA anchors lending, and TAZ is the loan token and the Aetherpost fee.

SOUL: 8 decimals
KCAL: 10 decimals
RA: 9 decimals, 10,000 total
TAZ: 9 decimals

Token	What it is	Where you need it
SOUL	The main token of the Phantasma chain. The top bar shows its price.	A small data fee on every transaction. Keep at least 1 SOUL.
KCAL	Phantasma's gas token, 10 decimals.	Gas for every action. A fraction of a KCAL for most, about 2,500 for creating a pool.
RA	Rare Asset. A fixed supply of 10,000, nothing more can ever be minted.	The anchor of Saturn Lending, and the token you pledge to lenders. See the RA guide.
TAZ	Transplanetary Artificial Zenith, 9 decimals.	The loan token in Lending, the reward paid on completed loans, and the fee for an Aetherpost dispatch.

RAA (Rare Astro Asset) is a different token from RA. Check the symbol before you trade.

Decimals, briefly

Each token has its own precision. KCAL has 10 decimal places, RA and TAZ have 9, SOUL has 8. Saturn Ops shows amounts in each token's own precision, and where the chain reports a figure on a common 8-decimal scale (pool reserves, claimable fees) the page says so.
