# Tutorials and Concepts ## 📖 Building Tips ### Developer Resources For developer resources on Serum and Solana: ### RPC Servers For a default list of RPC servers to use: * Others may be less reliable ### Serum Market Data If you want to consume Serum market data, you have the following options: * Javascript program for on-chain calls: * REST server: * Serum API: ### Mainnet, Devnet, Testnet Developers are recommended to have (by default) both a mainnet and devnet/testnet version with a toggle to test the protocol on both, as there may be differences in performance that are useful to be able to test: {% hint style="info" %} It is useful to have a devnet or testnet version, and also a mainnet version for full testing {% endhint %} ### Authenticating Transactions If you need to authenticate transactions, the recommended course of action is to use the SPL wallet adapter, which is what e.g. [sollet.io](https://sollet.io) users to connect to DEXes. {% hint style="info" %} Note: you can build in auto-accepting as an option! uses this with [sollet.io](https://sollet.io). {% endhint %} Users will be prompted to click: “Automatically approve transactions from [https://dex.projectserum.com](https://dex.projectserum.com/)” If they do, then for that session: * As long as the URL is the same * As long as the transaction contents match the expected contents (e.g. a DEX order) It will not require clicking "accept". This code is in . If you want your program to be auto-accepted, submit a PR (pull request) that adds it! * Bonfida and others also sometimes connect. {% hint style="info" %} Developers are recommended to use the same conventions as e.g. [sollet.io](https://sollet.io) for the seed phrase and private key. {% endhint %} ### Composability Consider composing with existing apps: * If your app needs liquidity you can trade on a DEX orderbook or swap * If your app needs to mint tokens, consider using [https://spl-token-ui.com](https://spl-token-ui.com/) * Check out for ideas and tools ### Fees Going to SRM Governance For fees going to SRM governance, you can assign to [this address](https://explorer.solana.com/address/7EEAZWuzNZTUSCdwrw1JS4eX9D8uTTL91owsk4GC3zNB/tokens) if you want. ## 🎓 Tutorials and Project Concepts ### 📈 Host a GUI Want to help support the Serum ecosystem?
