[Protocol Integration]: BEP20 support

[Milerius]

I propose to add the BEP20 smart chain binance protocol to be able to afford suitable and low costs in AtomicDEX

Benefits:

• Low fees
• Lot of pegged tokens such as XRP, ADA, DOT, BTC-BEP click here to see the list
• Lot of pegged stable coins such as DAI, BUSD also with low fees
• Binance gateway you can send BEP20 tokens directly to binance and then withdraw it from the real chain such as ETH

Requirements:

• Requires BEP-2 support because fuel is paid in BNB

Documentation:

• Academy BEP-20
• Academy BEP-2
• BEP-20 Interface
• Acknoledgements (Here we learn that Binance smartchain is a fork of Cosmos SDK but with interface similar to Ethereum
• Full Binance Smart Chain documentation

Should have some priority as BSC is getting lots of attention..

I could really use something like this right now.

KMD deposit times are 1-2 hours on Binance which is very inconvenient at times and still has to go through BTC first. I would use this pairing almost on a daily basis.

let's get KMD also on BEP20

Brilliant idea

I agree, it is a good idea, it was discussed today on discord but tokenize KMD on BSC is not related to AtomicDEX.

It seems that LTC and BCH are tokenized on BSC, I didn't find all details yet, here are some links I found.

How to join the BSC Cross-Chain Bridge

AnySwap Cross-Chain Bridge can dynamically add token support, and any ANY token holder (more than 1000 ANY token) can initiate a token cross-chain support proposal.

Initiate a proposal: https://vote.anyswap.exchange/#/anyswap/create

https://github.com/pancakeswap/pancake-swap-interface/blob/master/listing.md

https://lightrains.com/blogs/how-create-binance-token

5. List your token
   Once the proposal is passed, you can them list your token. The fee of listing is 800 BNB.
   Article is from 2019 so I hope that the 800 BNB listing fee was lowered.

I hope that we'll be able to get KMD tokenized on BSC and create a BNB KMD Liquidity Pool. https://github.com/phm87/pancake-frontend/pull/1/files
