Roadmap

Completed milestones are dated. Upcoming phases show the target windows from ROADMAP.md; they depend on funding and external reviews and are not commitments.

Prototypephase 1LIVE
  • 15 Aug 2026First shielded withdrawal confirmed on Ethereum Sepolia.
  • 23 Aug 2026Merkle tree fully on-chain (V3 pool): no operator step.
  • 3 Sep 2026Selective disclosure: spendKey / viewKey split, both proofs confirmed on-chain.
  • 19 Sep 2026Deployed and confirmed on Arbitrum Sepolia.
  • 24 Sep 2026Robinhood Chain Testnet, with LTH and USDG pools.
  • 4 Oct 2026V5 pools: recipient bound to the proof; 16 pools on three testnets.
  • 9 Oct 2026Distribution router deployed on Ethereum Sepolia; any-amount deposits on all four token sets.
  • 10 Oct 2026All four routers source-verified on Sourcify (exact match).
  • 11 Oct 2026Released demo run live on all four token sets: router deposits, withdrawals, disclosure.
  • 20 Oct 2026Latheon test chain live: Arbitrum Orbit on Arbitrum Sepolia, test LTH as gas, public RPC, explorer and faucet; native-coin pools and router confirmed with real proofs.
  • 21 Oct 2026Relayer live on the test chain: withdrawals without a wallet or gas.
  • 24 Oct 2026Bridge page live: test LTH between Arbitrum Sepolia and the test chain, both directions.
  • 26 Oct 2026V6 pools on the test chain: 1,048,576 deposits per pool, relayer fee bound into the proof.
  • 27 Oct 2026V7: fix for a flaw in all earlier circuits (withdrawal without a deposit), found in an internal review. Older pools frozen for deposits; the three external testnets deprecated.
Developer testnetphase 2target: 0–3 months6 OF 8 DONE
  • Test coverage, faucet, explorer integration, deployment automation, docs and SDK, contributing guide and threat model.
  • Independent review of the circuit (external).
  • Good-first-issue backlog.
Hardening and ecosystemphase 3IN PROGRESS
  • Stealth addresses.
  • Public multi-party trusted-setup ceremony.
  • SDK update for V7.
  • Controlled V7 gas re-measurement on the test chain and proof timing on named devices.
  • Pool-activity indicators and a payout planner.
  • Genesis Cohort for external builders: paused, not closed.
Mainnet readinessphase 4 · target: 9–12 monthsPLANNED
  • Independent security audit and cryptographic review.
  • Multisig with a timelock over the chain's owner powers.
  • Production hardening, monitoring, incident response.
Production chainlong term · 12–18+ months, funding-dependentVISION
  • Latheon's own chain on Arbitrum Orbit (framework chosen October 2026), with LTH as the gas token.
  • Still open: where it settles, data availability mode, the launch stablecoin, bridge privacy.
  • No launch date: comes after circuit review, a public ceremony and an audit.
