Oops.. okay
I'm trying to get my hands on an escrow system for exchanging crypto between buyers and sellers(more like my first solo project).. how can I implement that on bitcoin blockchain

That, could actually be possible. Bitcoin scripts are used for that exact purpose. Like, when certain conditions are met, execute this transaction

Not sure. Never really read about it

And its not solidity. Some other language

Oops!...alright..
Is there anyone here who has built a dapp, both smart contract and frontend?

I've a lot of question

Ask away

Okay..
I want to build an escrow system yeah.. this is how I imagine the flow..

Smart contract logic..
Withdrawals the crypto from the seller's wallet to an escrow address & upon confirmation of payment, the crypto get sent to the buyer....(is this logic implementable)

Challenges for that logic:
How do I integrate the sellers wallet with the smart contract, if the wallet is not a browser extension like meta mask..like of the seller uses a standalone app like trust wallet or imtoken.

If you really want it as a smart contract, there is one way I can think of

Accept Bitcoin, convert it into ethereum followed by conversion into wbtc. Then use that wbtc on the contract for whatever manipulation

Hmmm..okay.. I've actually scrapped bitcoin from the picture now,.. I'm just looking at ether, erc20 tokens, and bep20 tokens

Then its just a matter of functions

One function to accept ether
One to forward it so seller

And obviously buyer-seller mappings as suited

@mrrobot3_3

Fallback function is your friend🙂

Thanks... I will read on that
