Tether is about to enter the $25 billion crypto artificial intelligence sector, according to a post by its CEO Paolo Ardoino on X.

Tether AI, according to Ardoino, is a “fully open-source AI runtime, capable of adapting and evolving on any hardware and device, no API keys, no central point of failure, fully modular and composable, WDK-infused to enable USDT and Bitcoin payments.”

WDK is Tether’s Wallet Development Kit, a modular software development kit that enables businesses and developers to integrate non-custodial wallets and user experiences for Bitcoin and USDT across any app, website, or device, Ardoino explained in a November post on X.

On its Tether.ai website, Tether says its AI platform will integrate Keet, a peer-to-peer chat platform. Not much else is known about Tether’s AI initiative.

CoinGecko’s index of AI tokens is trading flat after the announcement.

Donald Trump is pushing back against claims that he’s profiting from the TRUMP memecoin, his official cryptocurrency that launched days before his presidential inauguration.

Chainalysis recently reported that the TRUMP token earned $900,000 in fees in a two day span for its backers.

The wallets of the largest holders of the token are controlled by CIC Digital LLC, an entity also used for his NFT collection, and Fight Fight Fight LLC, which is co-owned by CIC Digital. Collectively, they own 80% of the TRUMP tokens.

“I’m not profiting from anything,” Trump said during an interview with NBC News, adding that he hadn’t looked at the token’s performance and that any financial benefits would be incidental. “If I own stock in something, and I do a good job, and the stock market goes up, I guess I’m profiting,” he said.

The TRUMP token has seen strong market activity in recent weeks. It’s currently trading around $11.20, a significant drop from its all-time high of $44.19, but still up 20% over the past month.

Recently, the White House announced that the largest 220 holders of the $TRUMP token would be invited for dinner with the President.

Eric Trump, the son of President Trump, will be a headline speaker at Consensus 2025 in Toronto.

The Solana Foundation has disclosed a previously unknown vulnerability in its privacy-focused token system that could have allowed attackers to forge fake zero-knowledge proofs, enabling unauthorized minting or withdrawals of tokens.

The vulnerability was first reported on April 16 through Anza’s GitHub security advisory, accompanied by a working proof-of-concept. Engineers from Solana development teams Anza, Firedancer, and Jito verified the bug and began working on a fix immediately, per a post-mortem published Saturday,

The issue stemmed from the ZK ElGamal Proof program, which verifies zero-knowledge proofs (ZKPs) used in Solana’s Token-22 confidential transfers. These extension tokens enable private balances and transfers by encrypting amounts and using cryptographic proofs to validate them.

ZKPs are a cryptographic method that lets someone prove they know or have access to something, such as a password or age, without revealing the thing itself.

In crypto applications, these can be used to prove a transaction is valid without showing specific amounts or addresses (which can otherwise be used by malicious actors to plan exploits).

The bug occurred because some algebraic components were missing from the hashing process during the Fiat-Shamir transformation — a standard method to make zero-knowledge proofs non-interactive. (Non-interactive means turning a back-and-forth process into a one-time proof anyone can verify.)

A sophisticated attacker could forge invalid proofs that the on-chain verifier would still accept.

This would have allowed unauthorized actions such as minting unlimited tokens or withdrawing tokens from other accounts.

As such, the vulnerability did not affect standard SPL tokens or the main Token-2022 program logic.

Patches were distributed privately to validator operators beginning April 17. A second patch was pushed later that evening to address a related issue elsewhere in the codebase.

Both were reviewed by third-party security firms Asymmetric Research, Neodyme, and OtterSec. By April 18, a supermajority of validators had adopted the fix.

There is no indication that the bug was exploited, and all funds remain secure, according to the post-mortem.
