hailin 5e670e64b3 fix(blockchain): read token decimals from contract for deposit detection 
Previously decimals were hardcoded to 18, causing incorrect amount parsing
for USDT which uses 6 decimals. Now reads decimals() from ERC20 contract
when processing deposits.

hailin 2e6f22e9d8 fix(blockchain): read token decimals from contract instead of hardcoding 
The balance display was incorrect because decimals were hardcoded to 18,
but USDT uses 6 decimals. Now reads decimals() from the ERC20 contract.
