Confidential basket protocol on Miden.

Darwin lets users deposit underlying crypto assets and receive a single basket token whose Net Asset Value tracks a weighted index. All basket operations run natively on Miden with client-side STARK proofs — individual positions, balances, and NAV remain private by default.

ETH-native users skip Miden entirely: deposit ETH on Sepolia via 1Click or the canonical AggLayer (Bali) bridge, hold a Darwin basket position via the relay, and redeem back to Sepolia ETH via a trustless claimAsset call — all from a single wallet, in under an hour.

Reviewers / integrators:

• darwin-miden.github.io/darwin-docs/demo — end-to-end UX walkthrough with live tx hashes captured during verification (read this first)
• darwin-miden.github.io/darwin-docs/status — verified live state of every component
• darwin-miden.github.io/darwin-docs/architecture — system shape + storage layout
• darwin-miden.github.io/darwin-docs/contracts — every live Miden testnet + Sepolia address

• Four curated baskets: Core Crypto (BTC/ETH-dominant), Aggressive (pure crypto), Conservative (stable-heavy), Privacy Pack (catalog).
• v6 basket controller on Miden testnet (0x2a3ea0a268d97b80497d6a966e3141) with full storage maps for target weights, fees, per-user positions, and fee-recipient routing.
• Pragma Oracle integration for in-circuit NAV, with a transparent per-pair CoinGecko fallback when a Pragma testnet publisher is clearly broken. Read-only NAV view through the frontend: p99 = 24 ms (the proposal's 200 ms claim, 10× under).
• Canonical AggLayer bridging (Bali, network 76) for both directions: user-driven bridgeAsset for inbound, worker-driven B2AGG note + claimAsset for outbound. Full L1↔L2 round-trip verified end-to-end on testnet.
• An ETH-side relay (darwin-relay) so users without a Miden wallet deposit and redeem via either the 1Click broker (fast) or canonical Bali (trustless).
• Frontend with deposit panels (1Click / Miden-native), portfolio panels (positions, redemptions, claims), live NAV cards, and the BaliClaimPanel that wraps claimAsset calldata.
• Observability: relay /metrics Prometheus exposition + Grafana dashboard JSON; Playwright public-surface E2E (10/10 passing).

All repos are tagged at v0.4.0-m3 (or v0.4.1-m3 for darwin-relay) marking the demo-ready milestone.
