My attempt at learning Solana program (smart contract) development through RareSkill's Solana course.
Originally, I was trying to create a single anchor project and add the daily exercises under
programs(programs/day_1,programs/day_2,programs/day_x), but this made following along with the tutorial harder (longer running tests, Anchor not supporting deployment/testing of individual programs out of the box).
- Day 1: Hello World (and troubleshooting Solana installation)
- Day 2: Function arguments, math, and arithmetic overflow
- Day 3: Anchor function magic and the Interface Definition Language
- Day 4: Solana reverts, errors, and basic access control
- Day 5: Where is the constructor? About anchor deploy
- Day 6: Solidity Translations to Rust and Solana
- Day 7: The unusual syntax of Rust
- Day 8: Understanding function-like macros in Rust
- Day 9: Rust Structs and Attribute-like and Custom Derive Macros
- Day 10: Translating Solidity function visibility and contract inheritance to Solana
- Day 11: Block variables in Solana: block.timestamp and block.number and others
- Day 12: Beyond the block: Sysvars
- Day 13: Native Programs: Sysvars
- Day 14: tx.origin, msg.sender, and onlyOwner in Solana
- Day 15: Transaction fees and compute units
- Day 16: Accounts in Solana
- Day 17: Writing to storage
- Day 18: Reading Accounts from Typescript — an alternative to public variables and view functions
- Day 19: Creating mappings and nested mappings in Solana
- Day 20: Cost of storage, maximum storage size, and account resizing
- Day 21: Reading an account balance in Rust: address(account).balance in Solana
- Day 22: More differences: modifiers, view pure, payable, and fallback in Solana
- Day 23: Building a payment splitter: “payable” and “msg.value” in Solana
- Day 24: Authorizing various wallets to write to an account: "Pranking tx.origin"
- Day 25: PDA vs Keypair Accounts
- Day 26: Understanding Account Ownership in Solana: Transferring SOL out of a PDA
- Day 27: init_if_needed and the Reinitialization Attack
- Day 28: Multicall in Solana: Batching Transactions
- Day 29: Owner vs Authority
- Day 30: Deleting Accounts and Closing Programs
For the initial setup of dependencies required for Solana program development, follow the day 1 tutorial.
Then for creating a new Anchor project:
- Initialize a project:
anchor init day_x - Go to folder:
cd day_x - Remove git repository:
rm -rf .git(since60-days-of-solanais the main git repository) - Follow the tutorial for each day
Here is a list of common issues that I've encountered while going through the tutorials and how to resolve them.
-
Error: Deploying program failed: RPC response error -32002: Transaction simulation failed: Error processing Instruction 0: account data too small for instructionTo resolve this:
- Delete
