Solana CLI: Creating and Managing Wallets — Forge College

Why does key management matter for Solana development? Every signed operation you run locally — airdrops, program deploys, and transactions — depends on a local keypair and a reproducible wallet flow, so knowing how to create, inspect, and safely store keys is essential.

What you'll learn
In this lesson you will use the Solana CLI tooling to create an ed25519 keypair, confirm its public key, and document where keypair files live in a typical local-development-setup. You will run common commands such as solana-keygen new to generate a keypair, solana-keygen pubkey to read the public key, and solana config get / solana config set --keypair to confirm which key the CLI references. The lesson shows the CLI's default path behavior (for example ~/.config/solana/id.json), explains simple file-permission and backup practices appropriate for non-production workflows (chmod 600, avoid committing keys to VCS), and guides you to produce a short wallet_flow log listing file paths and commands used.

Who this is for
Beginner Solana developers with a terminal and the Solana CLI installed. Basic familiarity with the command line is assumed; no prior cryptography knowledge is required beyond knowing keypairs authenticate accounts.

Key topics covered
- Create a local keypair with solana-keygen new and save to a working folder
- Read the public key with solana-keygen pubkey and inspect CLI output
- Check and set CLI keypair references with solana config get / solana config set --keypair
- Default keypair file location behavior (e.g., ~/.config/solana/id.json) and recommended storage folders
- Secure local handling: file permissions (chmod 600), simple backups, and avoiding VCS leaks
- Produce a reproducible wallet_flow document listing files and commands used
