Smart Contracts
An Overview of the Charged Particles Smart Contracts


The Charged Particles protocol consists of a series of smart contracts, but there are four primary smart contracts that control the majority of the logic and are the only ones required to integrate with:
The primary contract for interfacing with the Charged Particles protocol. This contract controls the logic for viewing and updating a Particle's balances / nested assets.
Used to view and update rules for how the Charged Particles contract functions.
For viewing and setting permissions, approvals, and time locks on Particles.
Proton.sol / ProtonB.sol
The Proton contract is the base NFT of the Charged Particles system. It is a standard ERC-721 NFT with some added functionality. ProtonB provides the exact same functionality as the Proton, but has some minor changes for gas improvements, and was rolled out for V2 of the protocol.
