SolVPN offers free VPN access for $SOLVPN holders through the @vpnonsol_bot. It aims to solve privacy concerns, similar to DectraVPN which is a decentralized VPN based on Solana's P2P architecture. Both projects prioritize security and privacy, offering robust infrastructure with provided nodes. DectraVPN allows node staking to earn $DECTRA and uses tokens as a subscription method. SolVPN provides a convenient way to access VPN services for its token holders.
