Privacy Policy

TL;DR

Solobank is non-custodial software that runs entirely on your machine. We do not collect, store, or transmit any personal data, wallet addresses, private keys, or transaction history.

What we don't collect

• Private keys or seed phrases
• Wallet addresses or balances
• Transaction history or signing requests
• Names, emails, or any personally identifiable information
• IP addresses or device fingerprints

How the software works

All four packages (@solobank/sdk, @solobank/cli, @solobank/mcp, solobank) run locally on your machine. The CLI generates a Solana keypair stored in a local file during solobank init. All RPC calls go directly from your machine to the Solana network — no proxy, no intermediary.

Third-party services

The software interacts directly with:

• Solana RPC — for blockchain queries and transaction submission. Your RPC provider may have its own privacy policy.
• Jupiter API — for swap quotes and routing. See jup.ag for their privacy practices.
• Kamino & marginfi — for lending and borrowing. These are on-chain DeFi protocols; interactions are public blockchain transactions.

Blockchain transparency

Solana is a public blockchain. All transactions submitted through Solobank are visible to anyone. Wallet addresses, transfer amounts, and protocol interactions are permanently recorded on-chain. This is inherent to blockchain technology and not controlled by Solobank.

This website

The Solobank website (solobank.dev) is a static site hosted on Vercel. Vercel may collect standard web analytics (page views, country-level geography). No cookies are set by Solobank. No tracking scripts are loaded.

MCP server

The @solobank/mcp server runs as a local stdio process. It communicates only with the MCP client (Claude Desktop, Cursor, etc.) on your machine and the Solana RPC endpoint. No data is sent to Solobank servers.

Changes

If our practices change, we will update this page. Since we don't collect data, meaningful changes are unlikely.
