We had a data breach affecting the system powering Gnosis Pay-branded cards (our B2C business line) that resulted in the exposure of certain customer information.
Everyone affected was sent an email today with full information.
We deeply regret that this happened. While funds were not affected, the security of personal information is just as important and we take full responsibility.
Additional measures are in place until the B2C platform involved is fully retired as planned on 20 December 2026. In the meantime we encourage everyone to be even more vigilant. We will never ask for your PIN or seed phrase, or ask you to move funds.
Further Details: gnosispay.com/blog/data-brea…
We encourage security researchers to communicate security vulnerabilities directly with us via [email protected]. The same rewards apply as to Gnosis Chain: immunefi.com/bug-bounty/gnos…

NEW: @OlympusDAO has deprecated its legacy bridge & fully migrated to Chainlink CCIP as the canonical cross-chain infra for $280M+ of OHM.
Every OHM transfer across all seven supported chains runs on CCIP.
The great Chainlink CCIP migration continues.
$OHM bridging has fully migrated from LayerZero to @chainlink CCIP as the canonical bridge for OHM.
Building on our existing CCIP connection to Solana, the migration brings OHM on Arbitrum, Base, Berachain, and Optimism to CCIP while expanding it to Robinhood Chain for the first time, over all seven chains supporting OHM. Holders on those networks don't need to do anything, and their token addresses stay the same.
OHM sent from Ethereum is locked in a pool there and released when it comes back, so moving OHM between chains doesn't change how much OHM exists.
The upgrade was approved onchain in OIP-198.

NEW: ApeChain is deprecating its legacy cross-chain solution & migrating to Chainlink CCIP.
CCIP is now becoming the canonical cross-chain infra across the entire Yuga Labs ecosystem, starting with its flagship @BoredApeYC use cases, ApeChain, & the APE token.
Two communities. One ecosystem. One secure cross-chain standard.
ApeChain is working with @chainlink to strengthen our infrastructure for the future.
We will be migrating from LayerZero to Chainlink CCIP as our canonical cross-chain stack across the @yugalabs ecosystem, including @BoredApeYC.
With CCIP as our canonical bridge, $APE, $USDC, and other key assets on ApeChain are being upgraded to a Chainlink Cross-Chain Token (CCT).
This upgrade will make it easier for dApps, communities, and their assets to connect.

Today, Chainlink Labs filed our response to the @SECgov’s proposed transfer agent rules.
The SEC has a historic opportunity to modernize how markets track ownership.
We offer recommendations on records that span blockchains, transfer agent accountability, and the role of infrastructure like @chainlink.

If you're just starting in Web3 security, Solidity and EVM are a great place to begin.
Learn the fundamentals, participate in a few audits, and then consider exploring other languages and ecosystems.
Solidity is highly competitive, but less crowded ecosystems could offer you a better opportunity to stand out.

This season every Celtics player got a handwritten note from a former player who wore his number. Dillon Mitchell got one from Ray Allen. Mitchell Robinson got one from Isiah Thomas.

Thanks for asking. Having hundreds of banking and capital markets leaders at a Chainlink event is helpful for the present but also future months and years. Behind the scenes, there were dozens of meetings with current / potential partners during the event. We had multiple new announcements during the week some of which have already prompted inbound requests from other firms. Sergey discussed the importance of LINK during his keynote including the expectation that some future partnership announcements would include purchasing, holding, and paying with the token. Also got some helpful feedback from community members during the event that we already started discussing later that day. More things I am sure but those are some quick Halloween thoughts.
