	elCHR.sol

	elCHR, or El Chronos🐍 is a Liquid Staking Derivate for veCHR (Vote-Escrowed SoliSnek NFT).
	It can be minted by burning (veCHR) veNFTs.
	elCHR adheres to the EIP20 Standard.
	It can be staked with Guru Network to earn pure ETH instead of multiple small tokens.
	elCHR can be further deposited into Kompound Protocol to mint ibCHR.
	ibCHR is a doubly-compounding interest-bearing veRAM at its core.
	ibCHR uses elCHR's ETH yield to buyback more elCHRs from the open-market via JIT Aggregation.
	elCHR is the market ticker for Elite Chronos🌀.
	Price of 1 elCHR is independent and not affected by the price of CHR.
