Use Caution

Solana CLI Ledger & Keypair Cache (~/.config/solana)

Space: 1 GB – 10 GB+ developer Linux, macOS, Windows
Quick Answer: The .config/solana folder stores Solana CLI transaction history, test validator ledgers, and keypair files. Use caution.

Bottom Line: Use caution. ~/.config/solana contains Solana CLI configuration files, test validator ledger data, and default wallet keypairs (id.json).

What is Solana CLI Cache?

Located at ~/.config/solana/ on Linux and macOS, Solana CLI uses this folder to store cluster RPC endpoints, local test validator ledger states, and keypair secrets.

Can You Delete Solana CLI Cache?

⚠️ Use Caution.

  • Wallet Keypair Risk: Do NOT delete id.json unless you have backed up your private key seed phrase.
  • Test Ledger Data (Safe): You can safely delete test-ledger/ generated during local smart contract testing.
