DeFi project SafeDollar suffers exploit

The SafeDollar stablecoin project on the Polygon blockchain has reportedly suffered an exploit. The initial losses were estimated to be around $248 million, which could have caused the project to crash to zero. However, it now appears that the project only lost $250k.

Earlier reports from DeFi analytics websites DeFiPrime and RugDoc indicated that the attack wiped out $248 million from the project. This would have caused it to crash to zero. However, the SafeDollar development team didn’t issue an announcement via its official Twitter handle.

Instead, the protocol’s Telegram channel issued a warning of the attack to its users, urging them to suspend the trading of the SDO token. The team didn’t specify how much was lost in the attack but said they would announce a post-mortem once they conclude investigations. They also intend to compensate the liquidity providers.

The losses were later realised to be $250k. Popular cryptocurrency analyst Michaël van de Poppe made this known in his tweet. Mudit Gupta, a core developer at Sushiswap, also confirmed that it was $250k, and not the $248 million initially thought.

This is the second time SafeDollar has experienced an exploit in less than 10 days. The protocol detailed a post mortem on June 22, in an attack where it lost 9,959 SDS tokens, worth around $95,000 at the time.

Polygon DeFi protocols suffer exploits and rug pulls

The Polygon blockchain is in the spotlight following a series of exploits and rug pulls of DeFi protocols on its network. Earlier this month, the Malt Protocol experienced a collapse of the elastic supply for its algorithmic stablecoin.

Polywhale, another project built on Polygon was also shut down, with the developers dumping $1 million of their tokens and pulling an exit scam.

The Binance Smart Chain has suffered similar attacks on a few DeFi protocols. According to a Cryptonary report last month, BurgerSwap and Julswap experienced flash loan attacks, resulting in a loss of approximately $7.2 million.

Despite some of the poor press for Polygon recently, the project remains home to some leading projects. Recently, popular digital artist Beeple opted to launch his new NFT platform on the Polygon blockchain. Beeple holds the record for the most expensive NFT artwork auctioned to date, which fetched $69 million back in March.

Frequently Asked Questions

Can I trust Cryptonary's calls?

Yes. We've consistently identified winners across multiple cycles. Bitcoin under $1,000, Ethereum under $70, Solana under $10, WIF from $0.003 to $5, PopCat from $0.004 to $2, SPX blasting past $1.70, and our latest pick has already 200X'd since June 2025. Everything is timestamped and public record.

Do I need to be an experienced trader or investor to benefit?

No. When we founded Cryptonary in 2017 the market was new to everyone. We intentionally created content that was easy to understand and actionable. That foundational principle is the crux of Cryptonary. Taking complex ideas and opportunities and presenting them in a way a 10 year old could understand.

What makes Cryptonary different from free crypto content on YouTube or Twitter?

Signal vs noise. We filter out 99.9% of garbage projects, provide data backed analysis, and have a proven track record of finding winners. Not to mention since Cryptonary's inception in 2017 we have never taken investment, sponsorship or partnership. Compare this to pretty much everyone else, no track record, and a long list of partnerships that cloud judgements.

Why is there no trial or refund policy?

We share highly sensitive, time-critical research. Once it's out, it can't be "returned." That's why membership is annual only. Crypto success takes time and commitment. If someone is not willing to invest 12 months into their future, there is no place for them at Cryptonary.

Do I get direct access to the Cryptonary team?

Yes. You will have 24/7 to the team that bought you BTC at $1,000, ETH at $70, and SOL at $10. Through our community chats, live Q&As, and member only channels, you can ask questions and interact directly with the team. Our team has over 50 years of combined experience which you can tap into every single day.

How often is content updated?

Daily. We provide real-time updates, weekly reports, emergency alerts, and live Q&As when the markets move fast. In crypto, the market moves fast, in Cryptonary, we move faster.

How does the 3X Value Guarantee work?

We stand behind the value of our research. If the documented upside from our published research during your 12-month membership does not exceed three times (3X) the annual subscription cost, you can request a full refund. Historical context: In every completed market cycle since 2017, cumulative documented upside has exceeded 10X this threshold.
