Vitalik Buterin has presented a new Ethereum Foundation Mandate characterizing Ethereum as "sanctuary technology" designed to safeguard digital sovereignty and resist ideological dominance in cyberspace, according to the mandate description. The updated mandate positions the Ethereum ecosystem as infrastructure to protect users' control over their digital presence and limit online ideological monopolies.

USDT has exceeded 550 million users and is used chiefly as a "digital dollar" in emerging markets, Tether CEO Paolo Ardoino said. He added that Tether's largest single sender contributes less than 5% of activity, unlike some other stablecoins where top senders account for 25% of total volume.

Ripple's chief engineer has issued an urgent notice to XRP node operators regarding a critical network issue. The communication directs operators to review and implement an essential fix within the XRP Ledger.

The team behind the $TRUMP token transferred 5M tokens to a liquidity wallet about two weeks ago, then added liquidity in the $3.5–$3.8 range over the last three days while the token traded near $2.8, onchain analysis from @dethective shows. After an announcement of a gala luncheon naming President Donald J. Trump as keynote speaker pushed the token's price higher yesterday, that liquidity wallet converted the previously received tokens into roughly $1.8M USDC plus about $20K in fees. A separate wallet realized around $1M by using a single-price liquidity position that functioned as a sale without showing conventional dumping behavior, the analysis shows. The series of trades has prompted questions over whether profiting from such announcement-linked liquidity strategies falls within existing rules, according to @dethective.

Solana has approved the SIMD0266 upgrade proposal, which introduces a new ptokens model that could increase transaction speed by up to 19X, according to the project's latest update. The upgrade, proposed last year by Anza, is scheduled to go live in April, Solana Foundation Vice President Jacob Creech said. The ptokens model is expected to significantly lower token transfer costs and boost the network's overall transaction capacity.

Blockchain Capital transferred its remaining 216,292 AAVE, valued at $24.8M, to Coinbase Prime. Separately, whale address 0xFF5D withdrew 10,008 AAVE worth $1.15M from Aave and sent the tokens to Binance.

Pump.fun launched its "Tokenized Agents" feature on March 14, enabling automated token buybacks and burns after issuance, BlockBeats reports. Users issuing tokens for an Agent can specify a revenue-based buyback percentage by supplying the token contract and a Skills.md file to the Agent. Once cumulative revenue reaches at least $10, the system automatically executes buybacks and token burns based on these settings.

Aave has published a governance proposal to enable Aave V4 on the Ethereum mainnet, founder Stani.eth announced on X. The proposed upgrade introduces a modular architecture where Liquidity Hubs manage shared liquidity and Spokes set isolated lending markets with specific governance constraints, and includes topology, go-to-market pathways, implementation and control models, and an initial asset group for risk parameterization. If the community reaches consensus, the proposal will proceed to a Snapshot vote.

Grayscale staked an additional 57,600 ETH valued at more than $121 million, Cointelegraph reported on March 14, 2026. The move underscores sustained institutional interest in Ethereum staking, as larger firms increasingly put ETH to work rather than holding it idle. Market observers note that such large-scale institutional participation in staking can influence sentiment across the broader crypto market and may signal continued confidence in Ethereum's long-term utility.
