TransferChain S4
Secure Simple Storage Service
S3 was designed for simplicity. S4 was engineered for security.
With TransferChain S4, you get both simplicity and security — no compromises.
TransferChain S4
is our secure alternative to traditional object storage services like Amazon S3. Built with developers in mind, S4 combines the simplicity of an S3- compatible bucket with the powerful security guarantees of the TransferChain protocol.
Unlike conventional cloud storage, S4 ensures end-to-end encryption, client-side data control, and blockchain-based authorization — all by design. It’s a plug-and- play solution that requires zero infrastructure overhaul while delivering uncompromising data protection.
Blockchain-Based
Verification Network
TransferChain SDK doesn’t just offer secure storage — it gives developers access to a blockchain-native verification network.
Every action performed through TransferChain — from file uploads to permission changes — is recorded on our blockchain in real time. These transactions are immutable, time-stamped, and cryptographically verifiable, providing an auditable history that cannot be tampered with or altered.
Use TransferChain as a Trust Layer
TransferChain acts as a transparent, decentralized ledger that serves as the backbone of your application’s trust and compliance layer.
