I would like to complete this feature. But I do not know anything else except the title. Can you describe more about the feature? Or just give an example schema of token table like:

CREATE TABLE token(
   address String,
   totalSupply UInt256,
   decimals UInt8
   ...
)

Hello,

Along with symbol, normally these is a name metadata also, I suggest to add "name VARCHAR" to this table, what do you think?

Then it would be

CREATE TABLE tokens(
   address VARCHAR,
   name VARCHAR,
   symbol VARCHAR,
   decimals BIGINT,
   total_supply BIGINT,
   block_number BIGINT
)
