VanEck has launched three crypto exchange-traded notes (ETNs) tracking solana, TRON and polkadot.

The VanEck Vectors Polkadot ETN (VDOT), the VanEck Vectors Solana ETN (VSOL) and the VanEck Vectors TRON ETN (VTRX) are listed on Deutsche Boerse with total expense ratios (TER) of 1.5%.

The three ETNs track the MVIS CryptoCompare Polkadot VWAP Close index, MVIS CryptoCompare Solana VWAP Close index and the MVIS CryptoCompare TRON VWAP Close index.

The firm said the three digital assets were selected based on seven criteria, comprising of: functionality, number of transactions, availability on the exchanges, track record and development team and market capitalisation.

VanEck said it decided to expand its digital assets offering in order to “open up the future market of cryptocurrencies for European investors”.

It added that younger platforms may offer other advantages including lower transaction costs or faster processes.

Martijn Rozemuller, CEO at VanEck Europe, commented: “In total, there are around 10,000 different cryptocurrencies and no-one knows which will be the most important in 10 years.

“Investors should therefore be given the opportunity to invest broadly in digital assets as well. We are going to address that now.”

Over the past year, the firm has launched bitcoin and ethereum ETNs also on Deutsche Boerse. The VanEck Vectors Bitcoin ETN (VBTC) has a TER of 1% having halved its fee in March.
