Vitalik Buterin Unveils “Sanctuary Tech” Manifesto, Reframing Ethereum’s Ultimate Endgame - Crypto Economy

TL;DR:

• Buterin published a manifesto on “Sanctuary Tech”, his vision of Ethereum as a resilient, censorship-resistant digital space.
• ETH ETFs accumulate record positive flows: BlackRock registered over $110M in one week and Grayscale surpassed $170M.
• ETH price hovers around $2,100, with $2,000 as critical support and $2,300 as the next resistance level.

Vitalik Buterin published a manifesto on his X account in which he outlined his long-term vision for Ethereum under the concept of “Sanctuary Tech”. His proposal describes a network designed to function as an ownerless digital space, capable of resisting pressure from governments, corporations and surveillance systems.

Buterin acknowledged in the text that Ethereum has not achieved significant progress in areas such as privacy or financial freedom, and put forward the so-called “sanctuary technologies” as a response: structures that allow individuals and institutions to operate outside of external coercion. The manifesto went largely unnoticed due to global macroeconomic tensions and the lack of retail interest in the market.


Institutional Flows Hold Ethereum Up

While Buterin seeks to move the conversation to the technical plane, the market is focused on ETF flow data BlackRock, through its ETHA fund, accumulated more than $110 million in net positive flows over the past week Grayscale, with its two ETH and ETHE funds, surpassed $170 million in inflows since February 25.

Institutional capital continues to bet on Ethereum, even amid a context of broad market deterioration since the cycle highs of October 2025. Meanwhile, Harvard reduced its exposure to Bitcoin ETFs to redirect capital toward Ethereum.


The Level That Defines Everything

$2,000 is the support the market cannot afford to lose. Ethereum is currently trading around $2,100, posting a 6% recovery over the last 24 hours. If buyers hold that level, the next target is resistance at $2,300, which coincides with the February high.

A daily close above $2,350 would confirm that institutional flows are absorbing selling pressure. In the opposite scenario, a break below $2,000 could open the door to a drop toward $1,700, a zone identified as a potential capitulation point. Analysts note that three consecutive days of net inflows above $50 million into the ETFs, combined with a recovery above $2,300, could be the catalyst that brings the “Sanctuary Tech” narrative to the center of the market conversation.
