At the Celo Foundation we partner with organizations across the Celo ecosystem including partnering with cLabs, the team working on the open source platform Celo, whose mission is to build a financial system that creates the conditions for prosperity for all. Celo aims to remove the barriers for large-scale adoption of cryptocurrencies as means-of-payment.
Using a novel address-based encryption algorithm, the Celo protocol makes sending money as easy as sending a text. Additionally, Celo uses stable-value tokens pegged to fiat currencies, like the US Dollar, to minimize volatility.
Celo is an open protocol enabling many to participate in the system, even with a budget Android smartphone. The first application launched on the Celo platform, Valora, is a social payments and money transfer app, aimed at developing markets.
You Will:
- Use your knowledge and experience attracting traditional web2/mobile web developers coming into web3 to Celo
- Build awareness around the unique benefits of Celo’s PoS, mobile focused network.

- Help organize, build and train local developer communities and university developer groups
- Encourage and celebrate diversity in the communities you build
- Represent the community externally and internally and influence the engineering roadmap (SDKs, core specification) with your insights

You Have:
- 3+ experience working as a software engineer or engineering-focused developer advocate role
- Ability to distill complex concepts into easy to understand explanations

What is ERC20 example?
ERC20 is a standard for fungible tokens on the Ethereum blockchain
Here is an example of an ERC20 token
Let's say we create a new ERC20 token called ABC Token with a total supply of 1,000,000 tokens
Each token will be divisible up to 18 decimal places
To implement the ERC20 standard, we will need to define several functions, including:
- balanceOf(address): Returns the token balance of a specific address.
- transfer(address to, uint256 value): Transfers tokens from the caller's address to the specified address.
- approve(address spender, uint256 value): Approves a specific address to spend a certain amount of tokens on behalf of the caller.
- allowance(address owner, address spender): Returns the amount of tokens approved by the owner that the spender can transfer.
- User1 owns 500,000 ABC Tokens.
- User2 wants to buy 100 ABC Tokens from User1.
- User1 approves User2 to spend up to 100 ABC Tokens on her behalf.
- User2 calls the transferFrom() function with User1's address, his own address, and the value of 100 tokens.
- The transferFrom() function deducts 100 tokens from User1's balance and adds them to User2's balance.
