April 13, 2026 brings a heavy mix of news: Polkadot exploit, Bittensor fallout, and Trump tariff warning.

Here’s a quick breakdown of what’s moving crypto and global markets today as the Bitcoin price is trading around $71K.

Polkadot Exploit Sees 1B DOT Minted and Dumped

Polkadot has been hit by a major exploit that raised serious concerns across the market. An attacker managed to mint 1 billion DOT tokens and dumped the entire amount in a single transaction.

The tokens were sold for 108.2 ETH, worth around $237,000 at the time. The speed and scale of the transaction caught traders off guard, especially given the size of the minted supply.

Security firm CertiK pointed to a vulnerability in the Hyperbridge gateway as the main cause. The flaw allowed the attacker to forge messages and take control of administrative functions tied to a Polkadot token contract on Ethereum.

With that access, the attacker was able to mint tokens without proper authorization. The incident shows how cross-chain infrastructure can become a weak point if not properly secured.

The financial damage in this case stayed relatively small compared to the scale of the exploit. Still, the ability to mint such a large amount of tokens raises deeper concerns about system design and oversight.

Bittensor Crisis Deepens After Covenant Exit

Bittensor is facing a wave of criticism after a major contributor walked away from the network. Covenant AI, a key player in the ecosystem, completed what is claimed to be the largest decentralized LLM pre-training run ever.

The model reached 72 billion parameters and even outperformed LLaMA-2-70B. For many, this was seen as strong proof that Bittensor’s core idea could work in practice.

But shortly after that success, Covenant AI dumped 37,000 TAO tokens and exited. They also labeled the network “decentralisation theatre,” raising questions about the actual structure behind the project.

This move hit sentiment hard. A team that helped validate the tech decided to leave, which created doubts among investors and developers.

At the same time, Grayscale’s GTAO ETF continues to trade at a 50% premium to its net asset value. This shows a gap between market pricing and what is happening behind the scenes.

Before the exit, TAO futures were heavily leveraged, with a futures-to-spot ratio of 4.6:1. Around $3 billion in futures positions were built on the idea of decentralization, which is now being questioned by those closest to the project.
