# Built by someone who needed it.

Retina is a crypto portfolio tracker for people whose money is spread across wallets, chains and protocols, built by [3liXBT](https://x.com/3liXBT).

## It started as a spreadsheet.

Its founder tracked more than 50 wallets across EVM and Solana, yield positions on several protocols, Polymarket trades, physical gold and positions locked until different dates. No tool could answer the question that mattered most: how much does the whole portfolio earn per day?

Each tool answered part of it. DeBank listed what sat in EVM wallets, Jupiter did the same for Solana, and every protocol showed its own positions on its own page. Retina was built to answer the rest: what you own everywhere, what it earns, when it unlocks and how it changed. [Your Portfolio Needs New Tools](https://useretina.xyz/blog/your-portfolio-needs-new-tools) tells the full story.

## Who builds it.

3liXBT has invested in crypto since 2017 and writes about DeFi and onchain investing on X as [@3liXBT](https://x.com/3liXBT).

Retina reads public addresses through established onchain data providers and resolves every holding into one model, where each position has a chain, a protocol, an asset class, a type and a value.

## What you can rely on.

- **Read-only tracking.** Retina never asks for a transaction, a permit, a token allowance, a seed phrase or a private key.
- **Encryption.** Wallet identities, labels, settings and snapshots are encrypted with AES-256-GCM before storage.
- **Your numbers, calculated.** Ask Retina reads your portfolio; Retina calculates every figure in its answers.
- **No token.** Retina has no token and has never had one. Its only website is useretina.xyz, and anything else using the name is not Retina.
