Decimal usage

EVM Smart contracts do not recognize decimals. The general convention in Perp v3 contracts is all amounts use 18 decimal.

In cases where the native decimals of the token are used (e.g. USDT uses 6 decimals), the contract parameter will have XCD appended to it (cross to collateral decimal). E.g.

• amountXCD

• marginXCD
