Overview

FT4 supports the management of multiple assets. The asset table lists all registered assets:

entity asset {
   key id: byte_array;
   name;
   key symbol: text;
   decimals: integer;
   issuing_blockchain_rid: byte_array;
   icon_url: text;
   type: text = ASSET_TYPE_FT4;
   mutable total_supply: big_integer;
}

Account balances for assets are tracked in the balance table:

entity balance {
  key accounts.account, asset;
  mutable amount: big_integer;
}

warning

FT4 assets are not perfectly equivalent to ERC20. You can see the differences here.
