Location:Â Remote (North America)
Comp:Â Â $ 100k- $150k Annual
Candidate Requirements - Regions: Currently, we are not able to hire individuals that reside in Russia, China, North Korea, Cuba, Iran, Syria, Sudan, and the Crimean region of Ukraine. You will be required to prove your current residency location to ensure we as a company stay within the legal confines of US law.
Candidate Requirements - Interviews: The interview process for this role requires video meetings with the camera on. We must ensure the identity of who we potentially will be working with.
About Upside:Â Upside is a blockchain-based Web3 company focused on improving the way organizations operate and democratize access to interesting and valuable projects.
We do this by simplifying the process for businesses to launch and manage tokens - the building blocks of web3 native organizations. We've launched tokens worth over $1B that are held by more than 500,000 users including the tokens for FreshCut, Voyager, Gari, DappRadar, CERE, and many others.
We believe being a remote organization is an advantage, and we believe in the power of asynchronous work. To that end, we foster a collaborative community that can come together as individuals and in teams to build something truly special.

Why This Role Exists
We are looking for experienced Senior Solidity Smart Contract developers to help work on our open-source smart contract protocol. Â This includes the development of DAOs, NFTs, tokens, and wallet infrastructure across many blockchains like Ethereum, Solana, Avalanche, Polygon, and Algorand.
The right developer will have extensive Solidity Smart Contract coding experience, the ability to self-manage and prioritize clear and consistent communication skills, and a desire to write production-level smart contracts that people will use at scale. The ability to interface with clients is highly valued.
This role requires someone special: an expert developer that consistently ships high-quality code, with the ability to maintain a strategic perspective on the why of our features, not just the what.
This job is for an individual developer working full time and not an agency.
This job is 100% remote.
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.
