ethers.js

dive into - the tooling is more mature than other dev-centric blockchains. However, keep in mind that ethereum as a base can be a tricky place to launch your app because of high transactional fees, and you would likely want to integrate a layer 2 like Arbitrum or support alternative coins in a final application. I'll link some pages to a few technologies I used when building some ethereum dapps https://www.trufflesuite.com/truffle https://www.trufflesuite.com/ganache for wallet integration, either of these work https://github.com/ChainSafe/web3.js https://github.com/ethers-io/ethers.js I highly recommend checking out The Graph too - it allows for you to leverage graphQL on your smart contract data by creating a dedicated subgraph. With some careful integration, you can replace a dedicated backend that would normally be required for various APIs with this. It's a very exciting project imo. https://thegraph.com/en/ And of course, the solidity documentation is very helpful. Coming from a scripting heavy background, solidity was very easy for me to pick up and write a simple escrow service. https://docs.soliditylang.org/en/v0.8.9/ I'd also recommend checking out other chains once you become more comfortable with the system. I'm currently working on Solana and it's a bit more difficult to work with due to the tooling not being as mature, but it is a very interesting chain to work with and I hope that it can scale better than Ethereum has.
