Helius Medical Technologies (HSDT) announced on Monday it’s raising more than $500 million in a private financing round to create a Solana-focused treasury company.

The vehicle will hold SOL, the native token of the Solana blockchain, as its reserve asset and aims to expand to more than $1.25 billion via stock warrants tied to the deal, the press release said.

The financing was led by Pantera Capital and Summer Capital, with participation from investors including Animoca Brands, FalconX and HashKey Capital.

Shares of the firm rallied over 200% above $24 in pre-market trading following the announcement. Solana was down 4% over the past 24 hours.

The firm is joining the latest wave of new digital asset treasuries, or DATs, with public companies pivoting to raise funds and buy cryptocurrencies like bitcoin (BTC), ether (ETH) or SOL.

Helius is set to rival with the recently launched Forward Industries (FORD) with a $1.65 billion war chest backed by Galaxy Digital and others. That firm confirmed on Monday that has already purchased 6.8 million tokens for roughly $1.58 billion last week.

Helius’ plan is to use Solana’s yield-bearing design to generate income on the holdings, earning staking rewards of around 7% as well as deploying tokens in decentralized finance (DeFi) and lending opportunities. Incoming executive chairman Joseph Chee, founder of Summer Capital and a former UBS banker, will lead the firm’s digital asset strategy alongside Pantera’s Cosmo Jiang and Dan Morehead.

«As a pioneer in the digital asset treasury space, having participated in the formation of the strategy at Twenty One Capital (CEP) with Tether, Softbank and Cantor, Bitmine (BMNR) with Tom Lee and Mozayyx as well as EightCo (OCTO) with Dan Ives and Sam Altman, we have built the expertise to set up the pre-eminent Solana treasury vehicle,» Cosmo Jiang, general partner at Pantera Capital, said in a statement.

«There is a real opportunity to drive the flywheel of creating shareholder value that Michael Saylor has pioneered with Strategy by accelerating Solana adoption,» he added.

American Express has introduced Ethereum-based ‘travel stamps’ to create a commemorative record of travel experiences, as part of the firm’s revamped travel app.

The travel experience tokens, which are technically NFTs (ERC 721 tokens), are minted and stored on Coinbase’s Base network, said Colin Marlowe , VP, Emerging Partnerships at Amex Digital Labs.

The travel stamps, which can be collected anytime a traveler uses their card, are not tradable NTF tokens, Marlowe explained, and neither do they function like blockchain-based loyalty points – at least for the time being.

“It’s a valueless ERC-721, so technically an NFT, but we just didn’t brand it as such. We wanted to speak to it in a way that was natural for the travel experience itself, and so we talk about these things as stamps, and they’re represented as tokens,” Marlowe said in an interview.

“As an identifier and representation of history the stamps could create interesting partnership angles over time. We weren’t trying to sell these or sort of generate any like short term revenue. The angle is to make a travel experience with Amex feel really rich, really different, and kind of set it apart,” he said.

The Amex travel app also includes a range of tools for travels and Centurion Lounge upgrades, the company said.
