The core of ZERA’s True Digital Cash is now live on Solana mainnet.
This first dashboard beta ships the offline cash engine and unified pool core: you can deposit USDC into the Offline Cash program, mint a cryptographic offline voucher, auto-download a JSON backup file, and later redeem that voucher back into USDC with on-chain nullifier checks and full settlement on-chain.
Every deposit also wires into live $ZERA burn economics, so usage is already feeding real protocol value.
This is the base layer the rest of the ecosystem (mobile wallet, SDKs, merchants, more assets) builds on.
To set expectations clearly: this is an infrastructure-first release.
✅ Phase 1 (now): Live mainnet unified pool, USDC deposit/withdraw flows, ZERA burns, offline vouchers + nullifier set, and JSON backups.
✅ Runs on desktop/laptop browser only for now.
✅ Offline handoffs are a demo path only right now.
Each voucher is bound to a specific wallet (either your connected wallet or a recipient you choose on deposit).
You can back up, manage and move those vouchers offline, but this is not yet a production ready offline P2P flow.
Additional protocol logic and ZKPs are needed before we enable safe “pass-the-note” usage, and fees/parameters are set high on purpose to discourage heavy volume while we test.
Next up:
☑️ Double-spend-safe offline P2P on desktop/laptop, followed by mobile web support and QR/NFC-style handoffs.
☑️ Note-splitting and deeper privacy upgrades once the core rails are battle-tested.
☑️ Native iOS/Android wallets that sit directly on top of this engine, turning the unified pool into everyday private cash rails for people and merchants, with SDKs and integrations for apps that want cash-like privacy but on-chain settlement.
This beta is the floor, from here, expect regular, incremental releases that push more of our “True Digital Cash” into production without compromising on safety, compliance, or privacy.
