Aerodrome launches AERO rewards for MXNB/USDC pool on Base

Aerodrome Finance turned on AERO token emissions for its MXNB/USDC liquidity pool on June 12, 2024, paying providers both trading fees and protocol rewards for the first time on a Mexican peso‑backed stablecoin pair [1].

The MXNB token, a peso‑pegged stablecoin issued by Juno—a Bitso subsidiary—now joins the Base network’s largest DEX, creating a direct on‑chain bridge between the U.S. dollar and the Mexican peso. Under Aerodrome’s veAERO governance model, holders of vote‑escrowed AERO (veAERO) vote weekly on which pools receive emissions; the MXNB/USDC pair was selected in the latest epoch, meaning 100 % of the pool’s protocol fees flow to veAERO voters while liquidity providers earn AERO tokens on top of the usual swap fees [1].

Aerodrome’s dual‑pool architecture separates stable‑asset pairs from volatile ones, and the MXNB/USDC pair fits neatly into the stable‑pool category. By rewarding liquidity with AERO emissions, the platform aims to attract capital to a region‑specific stablecoin, a strategy it previously employed with the CTR/USDC pair. Bitso’s decision to launch MXNB on Base via Juno signals that the Coinbase‑incubated chain is becoming a preferred venue for institutional‑grade stablecoin projects in Latin America [1].

The move also dovetails with a broader push to grow DeFi activity on Base. Other projects, such as Mezo, cite Aerodrome’s infrastructure as a key draw for users on the network, where Bitcoin‑native applications have struggled to generate sufficient trading volume [2]. By expanding the pool roster with a fiat‑linked stablecoin, Aerodrome not only deepens liquidity options for Base traders but also reinforces the network’s appeal to institutional players seeking low‑slippage, low‑fee swaps.

For liquidity providers, the MXNB/USDC pool now offers a “double‑dip” revenue stream: swap fees plus AERO emissions, with relatively low impermanent loss risk as both assets are pegged to fiat currencies. However, the peg’s stability hinges on Juno’s reserve management and redemption mechanisms, which remain unverified by independent audits.

If the MXNB/USDC pair attracts sufficient depth, it could become the primary on‑chain conduit for USD‑MXN transactions, testing Base’s capacity to host cross‑border stablecoin flows and setting a precedent for other regional fiat tokens. The open question is whether the incentive model will sustain long‑term liquidity or merely subsidize short‑term participation.
