Last week the CurveDAO signaled that a new stablecoin is in the making. At that point, it was clear that Aave would also develop its own stablecoin since an initial proposal was already passed. Now the results are in on the second proposal and we have a little bit more details on GHO and most certainly more details than on Curve’s stablecoin project which seems to be also in an early stage.
What is GHO, how is it different from other stablecoins and can we trust this technology?
Aave is a decentralized lending system and one of the biggest DeFi protocols by TVL and other metrics. Users can lend or borrow crypto assets and stablecoins on Aave. By providing liquidity to the smart contract they can also earn interest.
The users who like to mint GHO will have to deposit one of the tokens or cryptocurrencies accepted by Aave. In this way, they are borrowing GHO against their crypto assets while at the same time earning interest on them. Aave will also allow to take out loans denominated in GHO. In return, the protocol will charge interest and use these fees to give them back to the Aave DAO.
One of the key differences here is that the value of GHO is pegged to US-Dollar by the value of the collateral borrowers are depositing. In order to ensure that the value of all deposits cannot drop below a sufficient threshold, GHO deposits have to be overcollateralized, meaning that users will deposit more in value than they receive in stablecoins. Should a user pay back his GHO to the protocol or should his deposit decrease in value, the GHO tokens are simply burned as the position gets liquidated.
There are always risks involved when using decentralized financial services that cannot be excluded. What most investors fear is a downfall similar to what we have witnessed with Terra. This is not possible with GHO since the stablecoins are backed by a basket of assets.
A death spiral like we have seen with TerraUSD that was only backed by LUNA is not possible. It is worth mentioning that there are still liquidation risks involved that would otherwise not occur when using a stablecoin backed by a company like Tether or Circle.
Judging from where decentralized stablecoins have started and how some of them have failed this year, the development of GHO is a positive thing for the DeFi economy. DAI from MakerDAO is doing well but it doesn’t scale easily. There is clearly a demand for decentralized stablecoins solutions and it is good to see that the industry is attempting to learn from Terra’s failure and mature.

In the last couple of days many misconceptions about stablecoins were discussed in the media. The FUD was juicy and the story was told that Tether (USDT) and Circle (USDC) had exposure to FTX and could face serious consequences. None of this is true and while FTX is imploding, stablecoins are not affected.

Solana is one of the fastest and most scalable blockchains and has a thriving DeFi ecosystem. Despite several hiccups and complete outages, this ecosystem is growing. It was last weekend during the Solana Breakpoint conference when Circle announced its new plans for Solana.

When summer started in earnest this year, the second biggest dollar stablecoin, USDC, started losing market share. It was a trend change from a years-long uptrend versus USDT. People were already preparing for 'the flippening': the moment where USDC would surpass the original stablecoin in market cap. What's going on?

Because we in Europe all have bank accounts and still a somewhat stable currency, we almost forget that there are entire continents where this is not the case. Latin America, for example. Chainalysis research shows that crypto transaction volume increased by 40% between mid-2021 and 2022.
