The decentralized liquidity staking protocol Diva Staking announced on social media that it will shut down the project and will not launch the mainnet. The official statement said that this decision was made after thorough discussion and apologized to the early stakers who had pre-deposited in the vault, stating that related deposits can be withdrawn through Enzyme without further waiting.The official statement mentioned that the team has been operating for about two and a half years without income or salary since the funds were exhausted in mid-2024, with three members pushing the project forward. Diva went live on the Hoodi testnet earlier this summer and has been running stably for about four months without any issues, but failed to gain support from large institutions for the mainnet launch. The three-member team also could not bear the costs of a new round of audits and mainnet operations, thus choosing to wind down rather than risk launching.The announcement also stated that the demand structure for LST has changed after the Shanghai upgrade. As of the end of June this year, BitMine, Coinbase, and Binance together accounted for about 30% of the total staked ETH, with approximately 11.5%, 10.9%, and 7.9% respectively, which is comparable to the concentration when the market was concerned about Lido's share being close to one-third. The official also congratulated Lido for advancing Simple DVT and opening up to independent stakers.

The decentralized exchange Osmosis based on Cosmos has terminated the issuance of OSMO tokens and shifted the source of staking rewards from newly issued tokens to protocol revenue.This adjustment eliminates approximately two percentage points of the staking annual yield supported by the issuance, while freezing about 51.9 million previously minted developer tokens.

On-chain treasury protocol Ducat tweeted that the team has decided to gradually shut down the protocol. The protocol design includes a price floor mechanism, and during the shutdown process, the team will prove that Ducat is fully backed by the treasury.The official team has taken a snapshot of the holders, and those who meet the criteria can redeem the corresponding fair value within the treasury without a cooling-off period. Tokens purchased from the liquidity pool after the snapshot will not be eligible for redemption.

Marinade, the Solana staking service protocol, released its Q3 2026 report. As of September 30, the amount of SOL staked was 7.94 million, a quarter-over-quarter increase of 21.2%, mainly driven by the non-custodial native staking product Native and the institutional-focused Select. The amount staked in Native increased by 47.3% quarter-over-quarter to approximately 3.77 million, while Select grew by 38.7% to about 1.68 million, and mSOL decreased by 6.8% to around 2.27 million.Revenue for the third quarter was approximately $1 million, corresponding to 10,918 SOL, a quarter-over-quarter increase of 25.9%, primarily from validator margin settlement income, which grew by 38.1% quarter-over-quarter. In the staking auction market, 48 out of 51 epochs in the quarter had yields higher than the Solana staking index, with an average yield before Marinade fees of 5.93%, compared to 5.67% for the index during the same period.In governance, since the implementation of MIP-22 in July, Marinade has used 10% of auction fees to repurchase MNDE on the open market. In the third quarter, a total of 4.2 million MNDE was repurchased with 906.6 SOL, and the first distribution opened on October 1. The report also disclosed that on September 25, attackers exploited a vulnerability in the DAO voting process to submit two malicious proposals, one of which involved transferring DAO treasury assets; the council vetoed both proposals within about 6 hours, and the fix was completed that night, with no funds being transferred.

The official listing account of the cryptocurrency exchange Kraken announced that the token SFI of the peer-to-peer risk-adjusted protocol Saffron will be launched soon, with trading starting on October 23.

The messaging protocol XMTP founder Shane Mac stated that XMTP will evolve into a self-operating open-source messaging stack, providing private conversations between people and agents, with infrastructure controlled by users, without requiring tokens or wallets. The network hosted by XMTP Labs will shut down in early 2027.Shane Mac mentioned that he founded XMTP five years ago because he believed that private messaging should not be owned by a single company. He recalled that the team envisioned using wallets as cross-application identities, allowing messages to follow identities, and using tokens to pay infrastructure operators, but this path was not realized. XMTP has never issued tokens and will not issue them now. He admitted that it was a wrong decision to persist with a single shared network for a long time, as developers have consistently requested the ability to self-host XMTP. Therefore, it has shifted to self-hosting, allowing developers to use, inspect, modify, and maintain the entire software suite without relying on Labs. Former employees will assist in maintaining the protocol, and Shane Mac himself will continue to be involved.The article introduces that self-hosted XMTP offers quantum-resistant end-to-end encryption, private one-on-one and group chats, encrypted identities, and message authenticity, as well as SDKs for mobile, web, server, and agents. Chief Technology Officer Nick Molnar has simplified the backend to a single Rust binary and integrated attachments, push notifications, handles, and signed webhooks for new messages. Each self-hosted network does not automatically interconnect by default, and agents from different tools must connect to the same backend to share conversations.

The Cardano ecosystem's decentralized trading and yield protocol Genius Yield is gradually ceasing operations. Co-founder Lars Brünjes stated on October 22 that to address the issue of users being unable to withdraw assets normally, an independent open-source tool called Genius Zero has been developed.Genius Zero allows users to bypass the original backend servers of Genius Yield and directly use Cardano smart contracts to unstake, cancel DEX orders, and withdraw assets. The original DEX trading fees still flow to the address controlled by Genius Yield, and adjusting the fee rates requires the signatures of at least three of the four original founders, which has not yet received sufficient authorization.

According to Salus monitoring, the attackers of Drift Protocol transferred 4,600 ETH, worth approximately 11.23 million USD, to Tornado Cash in 46 transactions from another long-dormant wallet between 15:00 and 15:19 Beijing time. This wallet had not made any outgoing transactions for about 202 days and still held 20,285.82 ETH at the time of monitoring.Salus stated that another wallet previously tracked had deposited an additional 6,110 ETH into Tornado Cash on top of the previously disclosed 19,600 ETH, bringing the total deposits of that wallet to 25,710 ETH. The two tracked wallets have cumulatively deposited 30,310 ETH into Tornado Cash.

SolanaFloor posted on platform X that Cardboardtrade, regarded as the Solana version of Papertrade's perpetual contract protocol, currently has an average daily trading volume of approximately 1 billion dollars. It is reported that the platform offers up to 1000x leverage trading for BTC, ETH, and SOL, with a total liquidation amount exceeding 564 million dollars and an open interest (OI) reaching 38 million dollars.A data screenshot provided by SolanaFloor shows that the total trading volume of the protocol is approximately 4.4 billion dollars.

The Bitcoin infrastructure protocol Echo Protocol announced on platform X that it will gradually terminate the operation of the protocol due to business adjustments. The official announcement expressed gratitude to the community, partners, and users for their long-term trust and support, and committed to completing the subsequent liquidation work transparently and responsibly.Currently, all core businesses of the Echo Protocol have fully stopped accepting incremental funds. The lending protocol has halted new deposits, new loans, and interest accrual, while the strategy and LSD businesses have also ceased new deposits and new pledges.The official has now opened repayment, withdrawal, and necessary asset liquidation channels, urging users to take action as soon as possible: lending users should repay debts, release collateral, and withdraw assets promptly; strategy and LSD users should initiate exits and claims as early as possible; users holding aBTC can continue to use the Aptos-to-B² cross-chain bridge for redemption.To ensure an orderly liquidation process, the announcement specified key timelines. All borrowers with outstanding debts must complete repayments by November 14, 2026, or face collateral liquidation, with the proceeds used to repay lenders. The final deadline for users to make repayments, withdrawals, and release pledges is November 19, 2026, at 23:59 (UTC).After this, the Echo Protocol will officially cease operations, and all remaining positions will enter the final liquidation and settlement process, with the platform only retaining the redemption service of the Aptos-to-B² cross-chain bridge. Since LSD and Strategy assets depend on the request time for underlying pledges/unpledges, the actual time users can claim will be affected by this factor.
