Test uses : Use env.mock_all_auths() for simple testing (allows all auth)
The decimal value (18 in your code) determines the divisibility of your token. It represents the number of decimal places that your token can be divided into.
0 - No decimals (whole numbers only)
6 - Common for stablecoins (like USDC)
7 - Native XLM decimal places
8 - Common for Bitcoin-like tokens
18 - Common for Ethereum-like tokens
Examples with Different Decimals
1 token = 100 base units
Smallest unit: 0.01
1 token = 10,000,000 base units
Smallest unit: 0.0000001
1 token = 1,000,000,000,000,000,000 base units
Smallest unit: 0.000000000000000001
Consider these factors when selecting decimals:
Industry standards
Gas efficiency (smaller decimals = less computation)
User experience requirements
Example Code with Different Decimals
client.initialize(&admin, &0, &symbol, &token);
client.initialize(&admin, &7, &symbol, &token);
client.initialize(&admin, &6, &symbol, &token);
Important Notes: The decimal value cannot be changed after initialization Choose carefully based on your token's intended use More decimals means higher precision but also more complexity Consider gas costs when working with large decimal values
