Injective Validator Spotlight 🔦 Today, we shine the spotlight on @zellic_io. Zellic is a major contributor to Injective’s network security by operating a validator among other governance, education, and ecosystem development work. Zellic is a security powerhouse doing security assessments for Fortune 500 companies to top DeFi protocols. Zellic claims to find the issues others miss. According to Zellic, in over 59% of their assessments they found critical/high impact issues that enabled the target company to fix outstanding issues before an attacker even had a chance.

📜Scallop Security Report - Post Cetus Incident Review Since the launch of Scallop, security has been Scallop's top priority to ensure our user's peace of mind as we scale and grow on @SuiNetwork. Over the months of development, the Scallop Team has implemented several security measures and initiatives to mitigate and prevent cases of exploit, be it on a smart contract level or user level. 🔒Security Initiatives by Scallop: 1. Open-Source Smart Contract: Scallop is the first DeFi protocol on Sui to make our smart contract open-sourced. By doing so, we allow developers to build on Scallop, as well as invite the community to review and identify any potential vulnerabilities in our smart contracts. 2. Bug Bounty Program: With a prize reward up to $300,000.00 USD, Scallop invites the Sui community to help us maintain the highest security standards through our bug bounty program. Each submission is reviewed seriously with severity taken into account. 3. Security Audits & Partners: All of Scallop's smart contracts have undergone stringent security audits with our security partners @MoveBit_, @zellic_io and @osec_io. With various security measures in place, we are thankful to share that Scallop's protocol and smart contracts are not affected in any way by the recent @CetusProtocol incident. Upon being notified of the exploit, Scallop Team took swift actions to pause all borrowing on Scallop DApp, therefore preventing any activity from the perpetrator on Scallop DApp. We have also conducted an internal review of Scallop smart contracts and protocol security, and confirmed that all user funds on Scallop are SAFU. Moving forward, Scallop is focused on further strengthening our protocol security through audits and reviews. We are also working on making several parameter adjustments based on the current liquidity on Sui to reduce the risk and limit the size of Scallop pools.

🧵 Protocol of the Day: @babylonlabs_io Babylon lets Bitcoin holders stake BTC to secure Proof-of-Stake chains, trustlessly, self-custodially, and without wrapping or bridging. ✅ Pros: • True self-custody—BTC stays in users’ wallets, no wrapping or third parties • Dual-use protocol—offers both BTC staking and timestamping to secure PoS chains • Audited and tested—reviewed by Coinspect, Zellic, and Cantina, with no recorded exploits • Top 5% by TVL—rapid adoption and growing role in BTC-enabled DeFi ⚠️ Risks: 🔸 Slashing risk – BTC can be partially slashed if validators misbehave on PoS chains 🔸 Architectural complexity – Uses Cosmos SDK and multiple modules, increasing operational risk 🔸 Validator trust assumptions – Relies on finality providers and delegated validator sets

Join the Spaces with the validators that are participating in the Rebate Campaign. 📍Thursday May 29th at 11:00 AM ET Learn more and participate in the community Q&A! Participating Validators: @zellic_io, @informalinc, @SCVSecurity, and @Kiln_finance https://t.co/hCZia6P6is

Honored to join this campaign alongside technical leaders like @zellic_io, @SCVSecurity, and @Kiln_finance. Strong validators make stronger networks.

Attention: $INJ Stakers 🚨 The Injective Validator Rebate Campaign launches today! This campaign is a strategic initiative that incentivizes delegators with rebates on their staked $INJ via validators who have consistently demonstrated their commitment to the Injective ecosystem. 💡Details: For the next 2 months, (May 27–July 27), new delegations to the participating validators can expect commission rebates for new delegations made during the campaign period. Participating Validators: - @zellic_io - @informalinc - @SCVSecurity - @Kiln_finance These validators have shown strength in technical infrastructure, governance, and expanding the developer ecosystem on Injective. To be considered for the rebate, delegators must fall into one of the following categories: 1. New Delegators: Stake $INJ with any participating validator between May 27-July 27, 2025 to receive commission rebates. 2. Existing Delegators: Add to your current stake with these validators during the campaign period—only new increments qualify for rebates. Join the campaign today through the Injective Hub and help secure the network and maximize your validator rewards!

In light of recent events, a reminder that security is a top priority for Thala – with the protocol having undergone 10+ audits conducted by leading security firms @osec_io, @zellic_io, and @spearbit.

Zellic is proud to be running a validator for @SaharaLabsAI! Zellic has worked closely with Sahara to audit components of their core contracts. We look forward to deepening our commitment to Sahara by supporting their efforts towards an AI-driven future.

Radix's Resource & Badge systems = game changers! 🛡️ @Zellic_io auditors highlighted how our native resource model eliminates common token handling bugs & praised the badge system: 'incredibly difficult to introduce access-control issues.' https://t.co/Yk3v4dRVxv

Peak nerdcraft like this is why we chose Zellic to audit STXN v1 👏

A journey from 'This is new...' to 'This is brilliant!' 💡 @Zellic_io's auditors experienced this firsthand with Radix's security model. Their initial caution transformed into praise for its elegant and robust design. https://t.co/43hYdLvMEE

🧵 Protocol of the Day: @SturdyFinance Sturdy V2 is a flexible lending protocol that lets you earn yield on almost any token. It uses a two-layer system: siloed lending pairs isolate risk, while aggregators spread capital across pools to boost returns. ✅ Pros: • Siloed markets prevent contagion across pools • Aggregators boost yield with automatic rebalancing • Audited by top firms like Zellic and ChainSecurity ⚠️ Risks: • Aggregator Trust – Managers control asset routing and risk management • Smart Contract Risk – One hack occurred in a prior version • Timelock Risk – Less than 48hr timelock may limit user response time to malicious upgrades

🧵 Protocol of the Day: @beefyfinanceBeefy is a cross-chain yield optimizer that auto-compounds rewards across dozens of DeFi protocols. With vaults on 30+ chains, it’s one of the easiest ways to boost yield on your crypto, all from a single interface.✅ Pros:• Auto-reinvests rewards to maximize yield• Supports 30+ chains including Base, Arbitrum, and Polygon• Audited by CertiK and Zellic with no hacks to date⚠️ Risks:• Anonymous Team – The team behind Beefy is not publicly known, which limits transparency and increases trust assumptions for users• No Reserves or Insurance – If something goes wrong (e.g. exploit or bad debt), there’s no safety net to protect user funds• Multisig Upgrade Risk – Smart contract changes are controlled by a small group with less than 48 hours of notice, giving users limited time to react

📢 Security Milestone Achieved: Swisstronik Audit by Zellic Successfully Completed 🛡️ We are proud to announce the successful completion of a comprehensive security assessment conducted by Zellic, one of the top blockchain security research firms in the world. 🔍 Scope & Methodology Zellic’s experts meticulously reviewed Swisstronik’s core modules, including EVM, Compliance, Vesting, and FeeMarket.

On this freezing winter evening, lets talk smart contract audits and recognize their importance within DeFi. The core Echelon codebase is currently 🧊 frozen 🧊 undergoing its 4th audit with 2 more scheduled to start after Christmas. By January Echelon will have received 6 audits: - 2 from @osec_io (lending core, isolated lending, e-mode, lending leverage, ongoing updates & review) - 2 from @zellic_io (lending core + Initia deployment, isolated lending) - 1 from @code4rena (lending core, isolated lending, ve token & boosted farming contracts) - 1 from @Quantstamp (comprehensive review) No number of audits fully guarantee security. Smart contract risk is very real and a major reason behind the on-chain risk premiums across DeFi yields. Even the MoveVM is not immune to economic errors or bugs in the code and all mainnet deployments should be reviewed extensively. The Echelon contributors are committed to extensive auditing and proper precautions. Visit https://t.co/g7PN69jOHs to view Echelon's audit reports and operational security practices.

We are excited to announce that $CHIRP token smart contract has been successfully deployed to the Sui Mainnet!
