Live now
The following ship as the phase-one product surface and are documented in the live pages:- Z Inference Gateway — single OpenAI-compatible API across four trust tiers (Anonymous, Private, TEE, End-to-End Encrypted).
- Trust tiers — cryptographically enforced; attestation verification mandatory before payload dispatch on Tiers 3 and 4.
- Settlement rails — Stripe (subscriptions and top-ups), x402 (per-request on Base and Solana with USDC), MPP (pre-authorized sessions).
- Zero Completion Insurance — first-class billing primitive applied uniformly across rails.
- ShieldedPool — multi-asset shielded pool on the host EVM chain.
- Z Trade — private trading venue.
- Z Lend — private lending market with USDZ and other bridged stablecoins.
Coming next
The following are committed work, sequenced for release. The order reflects current planning; specific dates are not committed in this document.Z Chain and the validator network
- Z Chain mainnet — sovereign L1 with EVM compatibility. Migration target for ShieldedPool, Z Trade, and Z Lend.
- Validator network — permissionless validator operation under Zcash Satoshi Plus consensus.
- Zcash Satoshi Plus (ZSP) consensus — dual-staked by ZEC and Z.
- Custom precompiles — Equihash verification, Blake2b hashing, optimized Groth16 verifier.
- Chain-native gas mechanics — replacing the host-chain gas model.
Chain-native utilities
- USDZ — chain-native stablecoin. Ships with Z Chain.
- yUSDZ — yield-bearing wrapper around USDZ.
- Z Stake — validator staking interface.
Bridge stack
- LayerZero bridge — ERC-20 bridge to and from Z Chain at chain launch.
- ZEC SPV bridge — direct shielded ZEC deposits and withdrawals. Post-chain-launch.
- FROST withdrawals — threshold-signature-based withdrawals.
SDK and developer tooling
- TypeScript SDK — primary Z-native SDK with full Tier 4 support.
- Attestation verification endpoint — raw TDX Quote exposed for independent verification.
- Python SDK with Tier 4 support — currently Python users access Tiers 1–3 via the OpenAI Python SDK.
- Rust SDK.
- Go SDK.
- Mobile (iOS, Android) SDKs.
- Sidecar pattern: a local proxy that lets OpenAI-compatible clients reach Tier 4 without using the Z SDK directly. Removes the SDK-language bottleneck on Tier 4.
Inference platform
- Community-hosted models — open registry for models served by independent operators.
- BYOK on Tier 1 — bring-your-own-key for enterprises with negotiated provider contracts. Architecturally rejected on Tiers 2, 3, and 4.
- Long-lived Tier 4 sessions — session continuity across mid-stream node failures, replacing the V1 hard-fail behavior.
- Z Compute as a general developer surface — the same verifiable-compute primitives that back the inference nodes, exposed for non-inference workloads.
Additional Zcosystem utilities
- Prediction markets, adjudication and betting, and additional patterns dependent on outcome oracles.
- Additional primitives beyond Z Trade and Z Lend.
Under exploration
The following are being investigated but are not yet committed to the roadmap. Inclusion here is informational; nothing in this list should be relied on by integrators.- Native non-EVM execution environments.
- Inference-time fine-tuning as a first-class API surface.
- Federated learning beyond the long-term ambient capability.
- A dedicated DAO governance layer separate from the chain-native governance design.
- Additional TEE hardware vendors beyond those currently supported.
- Additional payment rails beyond Stripe, x402, and MPP.
