Ethereum co-founder Vitalik Buterin said on X that algorithmic stablecoins are “real DeFi” and argued the industry should gradually move away from using the U.S. dollar as its unit of account, shifting instead toward broader diversified indexes. The comments add to his earlier remarks from January, when he outlined unresolved issues facing decentralized stablecoins.
ETH-backed designs remain central to his view
Buterin said that if high-quality algorithmic stablecoins backed by ETH existed, one important feature would be the ability to shift counterparty risk to market makers, even if most liquidity were supported by CDP holders carrying short algorithmic-dollar exposure. His framing was clear: the goal is not to erase risk completely, but to distribute it in a more effective way.
RWA-backed models can also work
He also said algorithmic stablecoins backed by RWA, or real-world assets, could be viable if overcollateralization and diversification are strong enough to keep the system fully collateralized even when a single RWA fails. The source article noted that the tokenized RWA market has already grown past $23 billion, with analysts projecting it could reach $16 trillion by 2030.
From dollar pegs to diversified indexes
Buterin argued that the industry should head toward reducing dependence on dollar-based accounting and adopt more general diversified indexes instead. That matches his January position that future stablecoins could track baskets of global commodities, energy prices, or custom consumer price indexes rather than only fiat currencies. The idea is broader than a simple peg. It points to a different reference system for on-chain value.
There is already evidence that this approach is hard to scale. Reflexer’s RAI, designed as a low-volatility token without a fiat peg, fell short of expectations in market capitalization, showing that user acceptance for non-fiat-referenced stablecoins remains limited.
Depositing USDC into Aave does not qualify
Buterin also singled out one example: depositing USDC into Aave does not fit his definition of decentralized stablecoins. The distinction suggests that, in his view, using a decentralized protocol at the interface level is not enough. The core architecture itself must be decentralized.
The article added that the total stablecoin market has surpassed $316 billion, while most growth still comes from centralized fiat-backed issuers. Decentralized alternatives have advanced much more slowly. Buterin’s latest comments put the focus back on stablecoin design, how risk is allocated, and what assets or indexes should anchor value on-chain.
