Metamask can be configured to work with any EVM compatible blockchain by adding networks. Social Media Manager – One of the first hires most projects take on is a social media manager because handling the “sir, when lambo” guys becomes a full time job in itself. Average salaries for senior Solidity developers in 2022 are in the region of $200k/yr with junior positions ranging widely depending on experience and abilities. Web3 developers tend tradefred to earn less as it’s less specialist but someone with previous web3 experience will likely get offered a premium over a generalist front end developer. These provide a good example of what quality Solidity code looks like, what is possible and how to do particular things and how the individual token contracts work on a fundamental basis. For web3 frontends there are also two options and this normally overlaps with the backend decision.
Transaction fees on these layer 2’s and alternate layer 1’s are usually much cheaper with contract deployment costing just a few cents in some cases. A good marketing and customer acquisition model is key to growing successfully. Marketing professionals can be split into data driven media buyers and creative PR types.
I’ve heard it being compared to more like hardware or circuit board development than other software. Much like in traditional web development key roles are normally divided into frontend and backend teams. Frontend web3 developers will usually be working on much more code heavy projects where design is an afterthought.
If you want potential look at recently launched projects and try and secure a token allocation in addition to your salary as most projects will have a vested team allocation for tokens. Salaries vary across the industry and are unfortunately dependent on where we are in the market cycle. From there you can read through your favourite DeFi projects code base and even try deploying is mcadam financial a pyramid scheme their contracts on your local testnets. A great resource for new and experienced developers is the open source nature of decentralised finance. The vast majority of projects make their code openly available to learn from, fork and play with. Truffle was the original node js application that has been used for many years to compile and migrate Solidity code to the blockchain.
Developer Roles
An access point provides an API to interact with to send transactions to a decentralised network. So the web3 javascript code will connect to an access point, sometimes called an RPC provider and that will relay messages to the rest of the nodes that form a peer to peer blockchain network. Going into 2022 the main choice developers need to make is do they want to develop on Solana or everything else.
As a first language I think it’s hard to make an argument for anything other than Javascript. The only exception would maybe be Python if you are specifically looking to get into more of a data analytics and machine learning role where this excels. For everything else learn Javascript in the browser and an in the console with Node JS. From there move on to a specialist area like Solidity for smart contract development. Javascript is also a much more versatile language as it can be used for web development, app development via Cordova, Desktop application development via Electron.

That’s because everything else with traction is based on Ethereum and runs the EVM . There’s the Ethereum layer 1 which has become excessively expensive for most developers with contract deployment costs currently running into thousands of dollars. A solution to this is a whole host of 3rd party projects which use the same code base and EVM as Ethereum but with varying levels of decentralisation.

My reasoning for this is that you’ll likely need to know Javascript as well because it’s used in deployment scripts and web3 etc. So learning Javascript initially is a lot more forgiving and will set you up to take on Solidity once you have a bit more experience with coding. UX / CRO Roles – User experience and conversion rate optimisation is often overlooked in the DeFi space. As time moves on and the industry becomes more competitive this will become key and there’s opportunities here for many projects to improve their conversion flow and usability. If you want stability then look for successful well funded organisations that have been around for a while and have a long term plan to make money in the industry.

Web3 Developer – Creates a website or dApp frontend which connects to a wallet such as metamask and interacts with the underlying smart contract. Web3 developers usually have some webdev experience and will work with Javascript for the main complexities. A testnet is a duplicate of the main network which has free worthless tokens. These are setup so developers can experiment and deploy and test contracts with no financial or security implications.
Hackathons are a great way to engage with other developers in the blockchain community. It can also be a good place to meet VC’s and investors if you are looking to raise capital. Note that you want to use a different wallet when working with programmatic transactions or testnet funds. This helps avoid the situation where private keys are pushed to public Github repositories. A couple of options here which kind of goes back to the truffle vs hardhat choice.
Ethers.js is newer, more refined and is normally used alongside Hardhat. If you can code a website then with a bit of practice you’ll be able to build a decentralised application and deploy it to the blockchain. Like anything else, practice makes perfect and what is intimidating at first becomes second nature after enough reiterations.
I’ve had some good results in the past which have brought in thousands of dollars worth of tokens in prizes. This is a little dated now but provides an excellent primer on smart contract security. Each challenge introduces a new way in which you the hacker needs to exploit a smart contract. You’ll need to use Solidity and remix to connect to the live game which runs on a testnet. In my opinion it would be unwise to learn Solidity as your first coding language.
I read somewhere that the International Space Station uses Javascript to run it’s UI. Smart Contract Developer – Working on backend smart contracts developing the core number crunching functions that need to be perfect with no room for bugs. Smart contract developers will usually work in Solidity for anything based on Ethereum or Rust for Solana. There are a number of roles within the blockchain sector and an understanding of what each of these does will help gauge where you fit in. Note that this article is mainly focused on frontend web3 development and backend smart contract development. The blockchain developer community is a welcoming bunch of geeks, libertarians and business men.
I would probably recommend Hardhat but use both myself on a regular basis. I create content about DeFi, systems trading and blockchain development. If you’ve enjoyed these resources could you help share this content on social media and send it to anyone who you think might benefit from it. There is also a lot of contract work available and no end of projects that want to pay you only in tokens. I’d suggest against taking these opportunities unless you are exceptionally confident the token will gain liquidity and traction in the future.
Also there’s SolHack which provides tutorials broken down into manageable bite sized modules with an active community. You’ll also need a web browser and a digital wallet to hold funds and pay transaction fees. Once you have Truffle Suite or Hardhat installed you’ll also want a text editor to open up code repositories and work on the code. Strong reasons for developing on Solana might be specifically targeting certain VC’s in the space (Alameda & Co) or requiring the high transaction throughput for a particular application.

Both are a valuable commodity in a noisy industry built on hype and attention. Smart Contract Auditor – A focus on security and preventing loss of funds. Auditors will assess code, look for edge cases and use tools such as fuzzers to perform assessments. A good starting point are Open Zeppelin’s libraries of token interfaces and helper modules.
Cycling For Fun
Community events are normally good fun, informative and great for getting a feel for where the industry is and where it might be heading. There are also a lot more resources for learning Javascript and there’s endless tutorials on Youtube. If you want to find out “how to get the second to last in an array with Javascript” you can just Google it and pick the top answer on Stackoverflow. Senior developers will cringe at this but when you are getting started it’s a great way to learn and get things done without getting stuck or brute forcing a solution. Backend development of smart contracts is very different to working with databases and micro services as well. There is no room for bugs, so each line of code needs to be meticulously considered before being committed.

Both have free tier usages which will suffice the majority of blockchain projects. A terminal is like an old school msdos prompt where you can run things from a command line. If you are a windows user then you can use the Powershell terminal, just hit the windows key and type powershell to launch a terminal. Occasionally node software can only be run on Linux or via docker which will require either a cloud instance or a VM like WSL .
Investment Analysts & Traders – There are plenty of research and trading roles available at the ever expanding list of VC’s and Prop trading firms in the industry. Legal Advisors – For projects operating in the US particularly it’s important to gain some legal counsel. The SEC has adopted a stance where it’s trying to assert and exercise authority in the space. Miners / Node Operators – Engineering based role managing hardware and core client software to enable the decentralised networks to operate. Many DeFi projects rely on existing infrastructure such as Infura but as they scale having independent infrastructure can be advantageous. Web Designer – This is often the same role as the web3 developer but someone with a creative skillset and experience with graphic design and CSS can add a lot of value.
Try to build and learn useful things, meet like minded people and keep it fun. Notable channels for developers include dApp university, Eat The Blocks, Eth Global and Alysia Tech. Ethereum has great documentation and I find myself referring standard life shareholder login back to it often. It’s worth having a browse through and more in depth study if you get a chance to do a deep dive. I code primarily in Windows and use Linux via WSL, if I had more time and patience I’d probably use Linux for everything.
