'Charta' is the latin word for 'letter or document'. We loosely appropriate this term as a codename for the smart contracts comprising the business logic of Dharma protocol.

Dharma is a protocol for generic tokenized debt issuance and fundraising on blockchains supporting requisite smart contract functionality (i.e. EVM blockchains). For a full description of the protocol's mechanics, a thorough overview can be found in the Dharma Protocol Whitepaper. This repository contains the core contracts that compromise the business logic for issuing and administering debt crypto-assets on-chain.

We use truffle for deployment, testing, and development, and use Typescript for testing and deployment.
