What is a Blockchain Oracle and why is it important?
Integrator Logo

Oracles are crucial components of a blockchain, as they provide smart contracts with the valuable information they need to function. Blockchains and their smart contracts are closed platforms that cannot natively access data from the outside world on their own. Oracles provide them with various real-world data forms, such as price information, the successful completion of a payment, the temperature measured by a sensor, sports results, and many more.

What distinguishes Charli3 from other Oracle solutions?
Integrator Logo

Charli3 is a decentralized Oracle designed from the ground up for the Cardano network. A fully Cardano-centric perspective lets us focus on the specific needs of Cardano and its projects, as well as take advantage of the features available on Cardano that other chains might not offer. This also implies easier integration with Cardano projects while also being more cost-efficient.

What is the C3 token and what is its utility?
Integrator Logo

The C3 token is a Cardano Native Token that powers the Charli3 Oracle. It is the currency used to pay the node operators for providing accurate data feeds. To get the data feeds, Dapps will be paying C3 tokens to the node operators per correct node value aggregated and so, therefore, supporting the perpetual utility of the C3 token.

*Although started as an ERC-20 token, the C3 token took its rightful place on the Cardano Blockchain on the 1st of May 2022. The maximum total supply of the ERC-20 C3 tokens will be migrating to Cardano in time.

Is there a maximum supply for the C3 token?
Integrator Logo

The maximum supply of C3 tokens is 100.000.000 tokens.

Is there a story behind the logo and name?
Integrator Logo

Charli3 took the approach of focusing our name on a character, to be more approachable and connect with people instead of only businesses. Charli3 is an homage to Charles Hoskinson, the “3” replacing the “e” is tech/leet speak given the industry we are in, as well as representing the 3 founders Damon, Jonas, and Robert.

Is Charli3 hiring?
Integrator Logo

Charli3 is not currently interviewing applicants for specific positions, but we are always looking for skilled individuals with a passion for blockchain oracles & how they can improve blockchain applications. So feel free to reach out by sending an email to [email protected].


How to buy the C3 token? And which wallet can I use to store my C3 tokens?
Integrator Logo

Important: always refer to the documentation of products you use to purchase and store tokens before taking any steps. Charli3 Oracle cannot be held responsible for any issues you might encounter using third party exchanges or wallets.

You can purchase the C3 token on the following decentralized exchanges:

→ Minswap

→ Muesliswap

→ Sundaeswap

→ Wingriders

Any Cardano wallet can hold C3 tokens, for example: Etrnl, GeroWallet, Nami, etc.

What is a CNT?
Integrator Logo

A CNT is a Cardano Native Token.
Cardano Native tokens are crypto assets that can be created and distributed natively on the Cardano blockchain and are able to interact with Cardano smart contracts. These tokens can include tokens, stablecoins, and NFTs.

Why is there an ERC-20 C3 token and a CNT C3 token on the market?
Integrator Logo

Some early Cardano projects, including Charli3, launched as an ERC-20 token since Cardano didn’t support smart contracts capable of investor lockup and vesting schedules to protect token price action. Since then, Charli3 has launched its CNT C3 token and urged people to bridge their ERC-20 C3 tokens to CNT C3.

The goal was always for C3 to be a Cardano Native Asset as the token utility for the Oracle is on the Cardano blockchain. Charli3 now solely supports the CNT C3 token. The ERC-20 C3 token is no longer supported and will have no future utility.

What happens with my C3 tokens after the Nomad Bridge hack?
Integrator Logo

The Nomad bridge hack of August 1st surprised everyone. Charli3 supported the use of this bridge, created by Nomad for users to be able to bridge their tokens from Ethereum to Cardano.

Your tokens, if purchased prior to August 1st, 2022, will be viable for bridging 1:1 to Cardano at a future date. (there is no timeline for this)

To know more about the hack and our response, please read our dedicated article: https://oraclecharli3.medium.com/charli3-update-post-nomad-hack-a3cd576237a0

What are the contract addresses?

IMPORTANT: do not buy ERC-20 C3 tokens as those are not supported anymore. If you have purchased ERC-20 C3, please read the Nomad bridge hack article.

ERC-20 contract address (for verification purposes only, not supported by Charli3 anymore):



What's the difference between 3rd party oracles and 1st party oracles?
Integrator Logo

The main difference between 1st-party and 3rd-party oracles is the way that data is fed into the blockchain. 1st party oracles are operated by the API providers themselves. 3rd party oracles take the data from APIs, and aggregate them, acting as a security layer between the data source and the blockchain.

What are the use cases for Charli3?
Integrator Logo

Some of the main technical use cases include:

→ Decentralized price-feeds

→ On-chain source of randomness

→ As an adapter to load off-chain data on-chain

These services can be used by many different DeFi solutions, stablecoins, Decentralized Exchanges, synthetics, and more.

Who can use Charli3 Oracle?
Integrator Logo

Charli3 is useful for any Cardano project that requires secure and accurate data feeds to run its smart contracts. That data is usually off-chain data, but can also be randomly generated values, on-chain feeds, and data aggregation for increased data accuracy or source redundancy.
