# Gem Wallet Integrates Aero DEX on Base, Robinhood Chain, and Arc: On-Chain Swaps for ETH, USDC, cbBTC, and More
> Swap ETH, USDC, cbBTC, and EURC on Base, Robinhood Chain, and Arc through Aero pools in Gem Wallet - learn how to get the rate straight from the blockchain.

Our new partner on Base, Robinhood Chain, and Arc is Aero: Gem Wallet integrated its pools in version 2.114.82, released on October 26, 2026, for iOS and Android. Now you swap ETH, USDC, cbBTC, and other tokens on these networks through Aero pools right on the blockchain.

## Gem Wallet Swaps Tokens on Base, Robinhood Chain, and Arc Through Aero Pools

Gem Wallet runs swaps on [Base](https://gemwallet.com/base-wallet/), [Robinhood Chain](https://gemwallet.com/robinhood-wallet/), and [Arc](https://gemwallet.com/arc-wallet/) through the pools of our partner Aero. The Aero DEX works fully on-chain, and with it, Gem Wallet has even more decentralized swaps - directly through smart contracts on the blockchain.

Say someone sent you [USDC](https://gemwallet.com/usdc-wallet/) on the Arc network, but you prefer to spend in euros. Choose EURC - Circle's euro stablecoin - and the wallet shows the rate from the Aero pool and the amount you will receive in advance: all that is left is to confirm the swap.

## What Is Aero?

<a href="https://aero.xyz/" rel="nofollow">Aero</a> is a cross-chain DEX and a unified liquidity layer for the Ethereum ecosystem: on Aero, people swap tokens, earn on liquidity, and launch new assets right on the blockchain. The Aero DEX launched on October 21, 2026, on seven networks at once, including Base, Ethereum, Robinhood Chain, and Arc, and in Gem Wallet it currently works on Base, Robinhood Chain, and Arc.

Aero unified two DEXs - Aerodrome on Base and Velodrome on OP Mainnet - and inherited their deep liquidity pools: the cbBTC pool on Base became the number one Bitcoin pool on-chain in 2025, with more than $107.7 billion in all-time volume, and the EURC/USDC pool on Base, where deep USDC and EURC liquidity helps Circle grow on-chain FX, gathered more than $3 billion in volume in 2025 (Aero data).

Gem Wallet works with Aero Slipstream pools - concentrated liquidity pools where liquidity providers keep tokens within a narrow price range. As of November 3, 2026, Aero Slipstream pools held about $121 million, and $4.1 billion in swaps went through them in the 7 days to that date (according to DefiLlama).

*cbBTC is a Bitcoin token backed 1:1 by BTC.*

## How Gem Wallet Finds the Best Rate in Aero Pools

Gem Wallet gets the Aero rate straight from the DEX smart contracts: the Aero quoter on a network node prices every suitable route in one request. Here is how a swap works:

1. **Pool Search on Your Device:** The wallet calculates the addresses of Aero pools for your pair at five tick spacings - 1, 10, 50, 100, and 200 - and checks them once against the Aero factory, the smart contract that creates pools.
2. **Route Comparison:** The Aero quoter compares a direct pool and two-pool chains at once, and Gem Wallet leaves out of the next quotes any route that falls more than 3% behind the best one.
3. **Trade Through the Aero Router:** The Aero smart contract moves your token along the chosen chain of pools, while the signature stays with you - you sign on your phone.

The table shows how much USDC Aero gave in Gem Wallet for ETH on the Base network for amounts from $100 to $10,000, Gem Wallet data as of October 26, 2026:

| ETH Swap Amount | How Much USDC Aero Gave |
|---|---|
| $100 | 99.52 USDC |
| $1,000 | 995.26 USDC |
| $10,000 | 9,952.56 USDC |

From $100 to $10,000, every dollar in ETH gives about 0.995 USDC: on this pair, a large swap barely moves the price in Aero pools (Gem Wallet calculation). Aero gives its best rate on pairs whose liquidity has moved to its pools - for example, cbBTC/USDC on Base.

*Tick spacing is a setting of a concentrated liquidity pool: the smaller the spacing, the more precisely the pool follows the price.*

## How to Swap ETH for USDG via Aero in Gem Wallet

1. Choose [ETH](https://gemwallet.com/ethereum-wallet/) on Robinhood Chain on the Gem Wallet home screen
2. Tap "Swap" and set the USDG dollar stablecoin as the token you receive
3. Enter the amount in ETH
4. Open the swap details: when Aero has the best rate, the provider row shows Aero and the amount of USDG you will receive

***Important:** The Robinhood Chain network fee for a swap is paid in the native token, so keep a small amount of ETH on your balance.*

## Benefits of the Aero Integration for Gem Wallet Users

Gem Wallet is a [self-custody wallet](https://gemwallet.com/self-custody-wallet/) for iOS and Android with 100% open-source code: in it, you securely store, swap, and stake crypto, and you can top up your balance with a credit card right in the app. Here is what the Aero integration gives our users when swapping tokens on Base, Robinhood Chain, and Arc:

- **Routes Through a Base Token:** If two tokens have no common pool, on Base Aero swaps through WETH, USDC, USDT, or WBTC, and you confirm the whole chain in one transaction.
- **Minimum Amount Check:** The wallet checks the minimum amount to receive against what actually arrived at your address, otherwise the swap does not go through.
- **Tokens Only to Your Address:** The recipient of the swap is always your wallet, and Gem Wallet rejects a route that does not start with the token you pay or end with the token you buy before you sign.
- **Approval Without Permit2:** Gem Wallet opens your token to the Aero router directly, and you sign it in one action together with the swap.
- **Built-In DEX Aggregator:** On every [swap](https://gemwallet.com/swap/) - say, USDC to ETH on Base - Gem Wallet compares provider rates and offers the best one, and if the pair has no Aero pool, the swap goes through another provider.
- **Simple and Clear Interface:** A swap through Aero takes a couple of taps and does not require connecting your wallet to websites or understanding pools - clear for beginners and convenient for experienced crypto enthusiasts.

*Permit2 is a separate permissions contract through which a smart contract gets access to your token.*
