OTC TTTT - Trustless Token Transfer Trade

You have a token that you want to sell but is not on exchanges and you seek OTC trade
You have giant bags of token that has $1k daily volume and you want OTC trade
You have a friend¹ and you offer him a 5% discount and you need OTC trade

¹ you meet a year ago at a conference and he is a cool guy but wouldn't trust with 1 BTC

If I was that smart I wouldn't be coding such a simple contract

Workaround: pass the rate to the kamikaze function. YEAH, I've called the function kamikaze because I want to make you think and read the code.

WTFPL + immutable laws of the universe (including but not limited to karma) are still in play.

Just don't be a dick or an asshole.

Disclaimer

It's crypto, DYOR (do your own research), always ensure you know what you are doing. Try on the testnet first. When on mainnet - try with a small amount. If you don't know how to deploy the code, you probably should not use it.
