FileShot.io might interest Solidity developers who care about the zero-knowledge and self-custody principles that underpin a lot of Web3 thinking.
The architecture is similar in philosophy to decentralized storage:
- AES-256-GCM encryption happens in the browser before upload
- The decryption key exists only in the URL fragment — the server is fully blind to the contents
- Zero trust in the server, just like you'd expect from a self-custody model
- Open source (MIT), self-hostable, no vendor lock-in
Not blockchain-based, but the zero-knowledge and trustless-server model aligns well with how Web3 developers think about data ownership.
