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.

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

The max supply of C3 tokens is 100,000,000, and it will remain unchanged.

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.

Right now, you can purchase C3 here:

→ VyFi

→ Minswap

→ MuseliSwap

→ SundaeSwap

→ WingRiders

You can check the price of C3 here: TapTools

There are multiple Cardano wallet options, such as GeroWallet, Yoroi, Nami Wallet, etc. We recommend GeroWallet, a truly all-in-one user-centric DeFi app governed by the community as a decentralized autonomous platform on the Cardano Network. GeroWallet simplifies the purchasing process as well, allowing users to purchase C3 directly inside of the wallet using their built-in DEX aggregator. To download GeroWallet, click here.

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.

What are the contract addresses?
Integrator Logo

IMPORTANT: Do not buy ERC-20 C3 tokens as they are no longer supported. If you have purchased ERC-20 C3 prior to August 1st 2022, please bridge your tokens by 05 April 2024 by
clicking here.

Please find below the correct C3 contract addresses:

→ CNT (Cardano Native Token) contract address:


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



How does Charli3 work? And why is it better than a general API call?
Integrator Logo

Dapps that manage data need security. Using a single API data source like Coingecko is a massive risk as it has no security for; removing bad data sources, data health checks, or outlying values. They are also a single point of failure that can be attacked and shut down easily

Charli3 uses a decentralized network of node operators to manage data for assets from as many sources as possible. The node aggregation protocol also has built in security features:

→ Data redundancy: Aggregation of many points of data from a set of node operators, ensuring data trust.

→ Data health checks: automatically making sure the data source is still reporting properly. If the health is off, that data is removed before the aggregations

→ Removed Outliers: Interquartile range, to ensure outliers are removed from data aggregation, keeping it accurate.

→ Fully auditable: on-chain records of all aggregations

→ Up to date: Data gathered directly from the source, not third party, for the most up to date values.

ANY project that offers trading/lending/borrowing/betting/payouts/synthetics, should be using an oracle for security. Using a single point API is dangerous.

What are the use cases for Charli3?
