🔍 Description

Rosetta is a block-level yield router for Hyperliquid.

Rosetta Indexer computes per-block supply/borrow rates across HyperEVM and HyperCore markets (e.g., Felix, Hyperlend, HLP vaults) and routes stablecoins to the highest net (cost-adjusted) yield in real time.

Two core ideas:

1- Block-accurate rate signal instead of event snapshots,

2- A cost-aware allocator that only moves when expected gains exceed switching costs (gas, slippage, market impact).

Net result: higher realized APY with fewer churns and tighter risk controls.

🛠️ How It Works

1. Data Plane (Signal)

• Our indexers read HyperEVM state each block and reconstruct effective borrow/supply curves per market.
• Normalize utilization → IRM → per-block accrual; stream to a time-series store for live and historical queries.
• Outputs: supply_apy, borrow_apy, utilization, liquidity and total_deposits flags.

1. Decision Plane (Allocator)

• Computes expected net benefit of switching: ΔAPR × expected dwell time − (gas + slippage + exit penalties).
• Cooldown windows prevent thrash; per-market caps/allowlists enforce risk policy.
• Objective: maximize rolling, cost-adjusted APY subject to liquidity, risk limits, and user preferences.

1. Execution Plane (Contracts + Router)

• RosettaRouter on HyperEVM executes atomic withdraw→deposit across supported protocols in a single tx.
• Guards: rate sanity checks, liquidity checks, circuit breaker, and emergency withdraw.

What’s interesting

1. Block-accurate rates: eliminates “flat lines between events,” so we don’t misprice micro-drift.
2. Cost-aware rebalancing: moves only when it pays after all-in costs.
3. Proof-of-performance: on-chain route receipts align realized APY with decisions.
4. Composable: any new HyperEVM market can be added via an adapter.
