Aerodrome Finance, the dominant decentralized exchange on Base, announced that the wrapped iShares 0-3 Month Treasury Bond ETF token, known as wtSGOV, is now eligible to receive AERO emissions. The move effectively lets liquidity providers earn DeFi rewards on top of exposure to one of the most boring, safe assets in traditional finance: short-term US Treasuries.

How the emissions mechanism works

Aerodrome runs on a ve(3,3) governance model, a system where holders lock up AERO tokens to receive veAERO voting power. Every week, veAERO holders vote on which liquidity pools receive AERO token emissions. Pools that attract more votes get a bigger slice of the rewards pie, which then flows to liquidity providers.

The annualized AERO emissions rate sat at approximately 10.9% as of April 2026. That’s the rate at which new AERO tokens are being distributed across eligible pools. For context, the underlying SGOV ETF itself yields whatever short-term Treasuries are paying, which means LPs in a wtSGOV pool are essentially stacking two yield sources on top of each other.

AERO has been trading in the $0.52 to $0.57 range recently.

What wtSGOV actually is

The wtSGOV token is issued by ST0x, a protocol focused on tokenizing real-world assets and making traditional ETFs available for on-chain trading and composability. In this case, ST0x wraps BlackRock’s iShares 0-3 Month Treasury Bond ETF, ticker SGOV, into a token that can move freely across DeFi.

SGOV tracks ultra-short-duration US government debt. The fund has significant assets under management, and its appeal is straightforward: near-zero duration risk, backed by the full faith and credit of the US government.

Putting that on-chain opens up possibilities that simply don’t exist in traditional brokerage accounts. Suddenly, Treasury exposure can be used as collateral, paired in liquidity pools, or composed with other DeFi primitives. The Aerodrome emissions eligibility adds another layer by creating additional economic incentives for providing liquidity around the asset.

The bigger RWA trend on Aerodrome

Aerodrome has been steadily expanding which pools qualify for emissions. In early June 2026, the MXNB/USDC pool gained emissions eligibility. Now wtSGOV gets the same treatment.

Aerodrome functions as the central automated market maker on Base, Coinbase’s Layer 2 network built on Optimism’s OP Stack. It leverages the Velodrome V2 architecture, which has proven effective at bootstrapping deep liquidity through its vote-directed emissions system.

What this means for investors

The combination of Treasury yield plus AERO emissions creates a dual-income structure. LPs providing liquidity for wtSGOV pairs earn trading fees, benefit from the underlying Treasury yield embedded in the token, and collect AERO rewards on top. That’s three potential income streams from a single position.

The risk calculus is worth examining, though. Smart contract risk from both the Aerodrome protocol and ST0x’s wrapping mechanism adds layers of exposure that don’t exist when you just buy SGOV through a brokerage. There’s also the question of AERO token price sustainability. At a 10.9% annualized emissions rate, dilution is real, and those rewards are only valuable if AERO maintains or grows its market price.

Investors should watch whether veAERO voters consistently allocate emissions to wtSGOV pools in coming weeks. The weekly voting mechanism means nothing is guaranteed. If the pool doesn’t generate enough fees or attract sufficient voter interest, emissions could migrate elsewhere.
