Why now? Smriti Verma (@OpenZeppelin) set out the institutional exposure problem and the tech landscape: FHE, ZK proofs and private state. Ryan Sauge @ADCDIII (@taurus_hq ) presented CMTAT Confidential, an implementation of the CMTAT token standard for confidential securities, built on @zama. Dominik Bepple (Seturion) showed confidential DvP in production: atomic settlement on public rails, with both the asset and cash legs encrypted in a single onchain transaction. Jimmy Tahoulas (@Swissquote) looked at what a public ledger means for client privacy. Pavel Jakovlev (@AMINABankGlobal) summed up what banks want: the regulator and counterparties see what they need, everyone else sees nothing.

We are happy to officially welcome @Nethermind to the CMTA. Nethermind has already contributed to CMTA's work through the FIX-CMTAT connector and its pre-audit AuditAgent tool has been applied to CMTAT contracts. Looking forward to advancing standards for tokenized capital markets together.

The Capital Markets and Technology Association (CMTA @cmta_ch) has launched CMTAT Confidential, powered by the Zama Protocol. Developed by @taurus_hq based on @OpenZeppelin’s confidential smart contracts, CMTAT Confidential extends the CMTAT standard with confidentiality.

🚨 $crvUSD depeging again as borrow rates have exploded to 40% crvUSD/USDC 0.985: If bitcoin starts cascading here due to $MSTR crashing, crvUSD will depeg very hard as the pegkeepers are empty and the pools are very imbalanced. There's only $2m of exit liquidity in each of the top crvUSD pools on Curve, so it won't take much to crush the crvUSD peg right now. The ratio is 10:1 😬😱 If @yieldbasis LPs start to panic at some point and begin to withdraw their BTC, the downward pressure on the peg will increase substantially!! Like I said many times before, CurveDAO was irresponsible to approve not only the initial 60m crvUSD credit line, but also the subsequent 300m credit line for YieldBasis without extensive real-world testing. RIP $YB $CRV $CVX 🪦
UPDATE #2: Significant depeg on $crvUSD now as pegkeepers exhausted all their reserves ⚠️ crvUSD/USDT trading down to 0.95 crvUSD/USDC trading down to 0.96 Borrow rates have spiked to 30% lol @yieldbasis is not good for crvUSD, only a matter of time before crvUSD/YieldBasis end up with a sizable chunk of bad debt!! $YB $CRV $CVX

Gmak, early this morning we received reports regarding an incident with the $DUSD Curve pool At this stage, the issue appears to be isolated to DUSD LP positions on Curve. There is currently no indication that other assets or deployments are affected. Underlying assets held in the Machines remain unaffected. As a precaution, security mode has been activated across all Machines while we continue to assess the situation. RECOMMENDED ACTION: We strongly advise LPs in the DUSD Curve pool to remove their liquidity. Our immediate focus is to fully understand the scope and impact on the Curve pool and to determine the appropriate next steps for affected users and LPs. Further updates will be shared as soon as the incident review is complete.

The path to tokenizing trillions in TradFi assets just got a lot clearer on Solana with CMTA's security token standard on Solana. CMTA's token standard is the regulatory-compliant framework for tokenized securities in Europe (Swiss DLT Act + MiCA aligned). Now it's native to Solana using already existing tooling including Token Extensions - no custom smart contracts needed. This means: ✅ Legal clarity for how to issue Swiss & MiCA aligned assets on Solana ✅ Leverages Solana's built in tooling so institutions can get up and running on Solana in minutes instead of months Traditional finance has been waiting for compliant rails. CMTA on Solana delivers exactly that: institutional-grade securities infrastructure with Solana speed.
New: CMTAT Solana Spec v1.0.0 CMTA releases guide for deploying CMTAT-compliant security tokens on @Solana. The spec details how the CMTAT framework for tokenizing financial securities can be implemented using Solana Token and Extensions Programs. github.com/CMTA/CMTAT-Solana

Earlier today, @newgoldprotocol was exploited for $2M in a price manipulation incident. The attacker swap the stolen token into the ETH using KyberSwap, bridged the stolen ETH to the Ethereum network using Across Protocol. The attacker then laundered the stolen assets through Tornado Cash. Attacker EOA on Ethereum: etherscan.io/address/0x86183… Attacker EOA on BNB Smart Chain: bscscan.com/address/0x0305dd… Attacker Contract Address: bscscan.com/address/0x2d2a69…

A couple of months ago, a team thought they lost ~$450k) by using the wrong contract to bridge to an Optimism L2. Neither the token nor the chain's team was any help. They reached out to me a few weeks ago, and I'm happy to say that as of today the funds are unstuck. 1/🧵
