About

When opportunity knocks, you gunna answer it? One Shot lets a user mint a rapper NFT, have it gain experience in the streets (staking) and Rap Battle against other NFTs for Cred.

OneShot.sol

The Rapper NFT.

Users mint a rapper that begins with all the flaws and self-doubt we all experience. NFT Mints with the following properties:

weakKnees - True
heavyArms - True
spaghettiSweater - True
calmandReady - False
battlesWon - 0

The only way to improve these stats is by staking in the Streets.sol:

Streets.sol

Experience on the streets will earn you Cred and remove your rapper's doubts.

Staked Rapper NFTs will earn 1 Cred ERC20/day staked up to 4 maximum
Each day staked a Rapper will have properties change that will help them in their next Rap Battle

RapBattle.sol

Users can put their Cred on the line to step on stage and battle their Rappers. A base skill of 50 is applied to all rappers in battle, and this is modified by the properties the rapper holds.

WeakKnees - False = +5
HeavyArms - False = +5
SpaghettiSweater - False = +5
CalmAndReady - True = +10

Each rapper's skill is then used to weight their likelihood of randomly winning the battle!

Winner is given the total of both bets

CredToken.sol

ERC20 token that represents a Rapper's credibility and time on the streets. The primary currency at risk in a rap battle.
