stETH/USD Market (MegaETH)

Status: ✅ Deployed on MegaETH (chainId 4326)

Harbor market with stETH collateral and a USD peg. This deployment uses the MegaETH manifest family (harbor_megaeth_v1, proxy keys like USD::stETH::*); it is not the same product stack as Ethereum mainnet markets (harbor_v1, fxSAVE/fxUSD–centric). Scope and comparison: Generic market deployments.

Market overview

Collateral	Lido stETH (wrapped for the minter per chain configuration)
Peg	USD — haToken proxy USD::pegged
Leveraged token	Proxy USD::stETH::leveraged (Sail-style exposure for this market)
Mechanics	Wrapped collateral in, pegged + leveraged tokens out; rebalances via stability pools (Minter, Stability pool)

Context (read once)

Topic	Detail
Token symbols / collateral ERC-20	Confirm on-chain via the minter’s immutable token addresses or a block explorer — not duplicated here to avoid drift from the registry table.
Stability pools	Collateral pool liquidates against the stETH/wrapped collateral leg; Sail pool liquidates against USD::stETH::leveraged. Manager: proxy USD::stETH::stabilityPoolManager.
Price oracle	Minter uses the Harbor stETH/USD wrapped aggregator (row below), not the chain’s standalone wstETH/USD feed.
Genesis	Proxy USD::stETH::genesis is in the registry; maiden-voyage calendar dates / zap addresses are not in the excerpted manifest — add when published under deployments or product docs.

Deployment registry (proxies, implementations, CREATE3 salts)

Single source for this market: all proxy and implementation addresses and CREATE3 salt (string) values. Deploy tooling maps each salt string to bytes32 for Bao Factory (0xD696E56b3A054734d4C6DCBD32E11a278b0EC458).
