Week 2 of hackathon submission interviews is now complete.

The Colosseum team will take a break this weekend and stroll through the garden. We will be touching grass, maybe feeding the ducks.

SafeChain isn't just a website. It's an open, on-chain Reputation Protocol. 🌐

Imagine wallets, DEXs, or NFT marketplaces reading our on-chain data to warn their users before they sign a malicious transaction.

We are building the trust layer for the entire @solana ecosystem. 🛠️

[SafeChain @SafeChainSolana]

Scammers move fast on-chain. You need to move faster. 🚨

SafeChain allows you to paste ANY @solana address and instantly see its community-rated Trust Score before you send funds. Let the community warn you so you don't make a mistake.

Trust, but verify. 🔍🛡️

[SafeChain @SafeChainSolana]

Crypto is global. Scam protection should be too. 🌍🛡️

We built SafeChain with instant localization so anyone can verify wallet reputation in their language. English 🇺🇸 and Ukrainian 🇺🇦 are live.

What language next? Let us know! 👇

Security tools shouldn't look like boring spreadsheets. 🎨✨

Unveiling UI for SafeChain: Pitch-black core, neon-cyan highlights, and sub-second load times. Building for the @colosseum hackathon means pushing both tech and design.

How do you like the look? 🥶👇

GM from the arena.

What are you building in the @Solana Frontier Hackathon?

[SafeChain @SafeChainSolana]

Why did we choose @phantom exclusively for SafeChain? Security and UX. 🛡️

By optimizing our Web3 Reputation Layer for a single, robust adapter, we deliver a seamless review experience on @solana. Zero friction. Maximum trust. 👻⚡️

@king__ask @phantom @colosseum Not fully yet - still polishing a few things.
We need to fix some minor issues and improve parts of the design, but overall it’s already working.

[SafeChain @SafeChainSolana]

Leaving a review should be entirely free. That’s why SafeChain is 100% GASLESS for users. ⛽🚫 You sign the review via @phantom , and our relayer covers the network fee. Seamless Web3 UX is here. #solana @colosseum

How do you rate a wallet without getting spammed by bots? 📷 Math. Our @solana smart contract uses exponential smoothing for the Trust Score and enforces a strict on-chain cooldown logic. No fake reviews, only real reputation. Building hard for @colosseum 📷
