CREATE A CUSTOM DEFI APP (Neplease preffered)

I need to create a custom defi app on Tron blockchain

1) Create frontend and connect with Tronlink browser plugin so that people can login using Tronlink
2) Create a DASHBOARD (there already is )
3) Implement staking (Mongo Based not chain based --> code already is there need to update)
4) Create realtime price graph (based on market pair of tokenA:tokenB)

The above codes are almost there so developer should be able to extract and redeploy

1) Make the frontend able to connect to steem blockchain using steemkeychain
3) Make use of steemjs to listen to incoming transaction in an specific account (i.e incoming steem transactions)
4) Execute tron transaction based on the steem transaction
5) enable steem vote selling by using steem token itself or trc20 tokens on our platform
6) enable steem staking using trc20 token (mongo based)

further stuffs can be discussed later in chat

musk know
1) tron blockchain
2) steem js
