The network is optional.
Transactions aren’t.
A research‑driven initiative focused on building resilient,
offline‑first payment infrastructure for the Solana ecosystem.

Zypp Ecosystem
Zypp Wallet
Create, sign, and store transactions offline, then submit when connectivity is available.
Zypp SDK
Developer toolkit for building offline-first transaction flows on Solana.
Zypp Relay
Asynchronous transaction broadcaster for submitting transactions when networks become available.
Zypp Research
Ongoing research into offline-first systems, delay-tolerant networks, and transaction reliability.
Protocol
Architecture
Create
Cryptographic signing occurs locally. Private keys never leave the hardware boundary.
Store
Encrypted transaction payloads are persisted in a local, secure queue.
Submit
Broadcast occurs via asynchronous relay nodes upon network re-entry.

Research on offline-first systems, transaction reliability, and network resilience.
Analysis:
Why it Matters
Most financial systems assume constant internet access.
In reality, large parts of the world operate under unreliable, intermittent, or no connectivity at all. Digital infrastructure often fails where it is needed most.
When networks fail, transactions fail. Payments don’t go through. Financial systems break when they lose their connection to the cloud.
“We’re building for the environments where this is the norm, not the exception.”

Evolution
We’re building the foundation for offline-first financial systems.
