Native token of the Solana blockchain. Fast, cheap, and liquid—which is why it's useful for domain payments if you want to move money without banks or KYC intermediaries.
SOL powers transaction fees and smart contract execution on Solana. Unlike Bitcoin or Ethereum, Solana trades speed for decentralization claims; network outages happen. But the token itself is straightforward: send it, receive it, no permission needed. For domain registrations, SOL works well because exchanges list it widely, liquidity is deep, and transaction finality is fast (seconds, not hours).
Bunkerdomains accepts SOL payments specifically because it's liquid enough to convert quickly if needed, and popular among the crypto-native crowd who value the ability to register pseudonymously without bank approval. If your threat model includes financial surveillance, SOL moves faster than traditional payment rails. If your threat model includes total blockchain privacy, use a privacy coin instead—SOL transactions are public on-chain.
