Weekly Project Updates: OpenSea Delays TGE, Aster Chain Launches Mainnet and Staking, Stablecoin Chain Tempo Goes Live, etc
1. Vitalik Buterin: Ethereum Implements Fast Finality, 12‑Second Single‑Slot Irreversibility link
Ethereum co-founder Vitalik Buterin introduced a new fast-confirmation rule mechanism for Ethereum on X. The mechanism allows users to obtain a hard guarantee that Ethereum transactions will not be reverted after only one slot, which takes 12 seconds. Vitalik noted that the security of the rule relies on two premises: first, the vast majority of validators are honest nodes; second, network latency is below approximately 3 seconds. Although its security is slightly lower than economic finality, it already offers strong reliability for many application scenarios.
2. OpenSea Delays SEA Plan, Ends Rewards and Refunds Fees for Round 3–6 Users link
OpenSea CEO Devin Finzer announced in a post that, amid challenging crypto market conditions, the launch of OpenSea’s native token SEA — originally scheduled for a March 30 event — has been delayed. A new timeline will be determined separately by the OpenSea Foundation. The platform will conclude its existing reward program cycles and offer users who participated in reward waves 3 through 6 the option to receive a platform fee refund; those who choose the refund will have their corresponding Treasures rewards removed.
3. BONK.fun Relaunches, Promises 110% Compensation for Hack Victims link
BONK.fun officially announced that its website has been restored. According to the official post‑mortem, on March 11, hackers hijacked the website through a social engineering attack targeting its domain service provider, resulting in the unauthorized transfer of the domain. The official emphasized that none of its internal systems, codebase or team accounts were compromised, and the domain service provider has taken responsibility for the transfer. The official estimated total user losses from the security incident at around $30,000, and pledged to compensate affected users at 110% of the loss amount to cover their opportunity costs. Control over the main domain has now been recovered.

Users can obtain veASTER through lock-up (up to 208 weeks) to increase their earnings weight. The initial set of validators includes Trust Wallet, BNB Chain, World Liberty Financial, Lista DAO and PancakeSwap.
On March 17, Aster announced the official launch of the Aster Chain mainnet.

5. WLFI Unveils Open-Source Self-Custodial AgentPay SDK link
WLFI has announced the launch of AgentPay SDK, an open‑source self‑custodial software development kit. It enables AI agents to hold, transfer, and transact with USD1 on EVM‑compatible blockchains, positioning USD1 as the economic operating layer for autonomous AI systems. The SDK integrates self‑custodial key management, policy‑based transaction authorization, local signing, and a plugin mechanism. It can connect to tools such as Claude Code, Codex, and Cursor, runs locally without transmitting data to WLFI, and supports both policy‑driven automated execution and manual approval. Currently, it supports Ethereum and BSC with USD1 pre‑configured, offers over 40 CLI functions, and integrates with Bitrefill. The roadmap includes advancing EIP‑3009 gas‑free transactions, proposing agent payment standards, expanding the plugin ecosystem, and enabling cross‑chain and cross‑border payments.

The open interest (OI) across Hyperliquid’s HIP-3 (Permissionless Market Creation Protocol) markets has surpassed $1.43 billion, hitting an all-time high. Data shows that the WTI crude oil perpetual contract has performed exceptionally well, with a 24-hour trading volume reaching $1.39 billion, ranking second on the entire platform — behind Bitcoin and ahead of Ethereum.

10. Tally, Governance Platform for 500+ DAOs, to Shut Down After 6 Years link
Tally, a governance platform that has served over 500 DAOs including Uniswap, Arbitrum, and ENS, announced it will shut down after six years of operation. Tally CEO Dennison Bertram stated that the strict regulatory environment under former SEC Chair Gary Gensler during the Biden administration had driven projects to adopt decentralized governance via DAOs to mitigate legal risks. However, the current more lenient regulatory landscape has made DAO governance an optional rather than necessary choice, thereby weakening demand for governance tools.
