MegaETH Price Oracles
Chain ID: 4326
Active oracles: 3 (BTC/USD, wstETH/USD, Harbor stETH/USD)
Deprecated (legacy): 4 USDMY/* feeds — the USDMY protocol ceased deployment and operations on MegaETH. Contract addresses below are kept for reference only.
Overview
MegaETH lists direct BTC/USD and wstETH/USD feeds, a Harbor stETH/USD wrapped aggregator for markets, and legacy USDMY pair contracts. USDMY is deprecated on this chain; do not use USDMY feeds for new integrations.

- No rate provider needed (direct USD pricing)
- Version 4 contracts (no proxy pattern)
Harbor market aggregators (wrapped price)
| Oracle pair | Address | Status | Version | Notes |
|---|---|---|---|---|
| stETH/USD | 0xEDd3dC3E699360846c87CB69052EcbC900201854 | Active | v4 | Used by stETH/USD Market (MegaETH); salt harbor_megaeth_v1::stETH::USD::wrappedPriceAggregator |
USDMY pairs (deprecated)
The USDMY protocol is no longer deployed or operated on MegaETH. The following contracts were part of that stack and are documented only for historical reference.
| Oracle Pair | Address | Status | Version | Rate Provider | Price Feed |
|---|---|---|---|---|---|
| USDMY/BTC | 0xf9cB23E2E882C67A899C448CBe2542df9eebC615 | Deprecated | v4 | USDMY | BTC/USD (inverted) |
| USDMY/ETH | 0x756B95D0bB61c195d1196EB2143D8D88570036AC | Deprecated | v4 | USDMY | ETH/USD (inverted) |
| USDMY/HYPE | 0x830AB2B3A936F727ee2FF67E9C073380B6f166D8 | Deprecated | v4 | USDMY | HYPE/USD (inverted) |
| USDMY/SOL | 0xE2962ab29C723415F023451E9F166122d8b4a980 | Deprecated | v4 | USDMY | SOL/USD (inverted) |
Note: When USDMY was active, pairs used the USDMY token as rate provider and inverted price feeds to quote USDMY against each asset. These deployments are immutable v4 contracts; they remain on-chain but must not be treated as supported protocol infrastructure.
Market integration
- stETH/USD Market (MegaETH): Uses Harbor
stETH/USDaggregator (0xEDd3dC3E699360846c87CB69052EcbC900201854)
Version Information
- All listed contracts use v4 bytecode; active Harbor and direct-feed paths remain the integration surface for MegaETH today
- USDMY oracle rows are deprecated alongside cessation of USDMY deployment and operations on MegaETH
- Direct-feed and deprecated USDMY oracles are immutable (no proxy)
- Harbor wrapped aggregators used by markets may use UUPS proxies (see deployment manifests)
Notes
- Smaller oracle deployment compared to other chains
- USDMY coverage (BTC, ETH, HYPE, SOL) is deprecated on MegaETH; rely on active direct feeds and Harbor market oracles
- All contracts are v4 (Harbor market aggregators such as stETH/USD may use upgradeable proxies per deployment manifests; direct-feed oracles are immutable)
