Гаманець для DoubleZero

What is DoubleZero (2Z)?

Most crypto networks move data over the public internet, and that is where DoubleZero steps in: it is a dedicated network of fiber links contributed by independent operators, built so that validators and other high-throughput systems can exchange blocks and transactions with lower latency and less jitter than ordinary routing allows. The first and main users are Solana validators, which plug into the network to receive and forward data faster than they could over the open internet.

2Z is the token that runs this arrangement. Validators and other users of the network pay for connectivity in 2Z, and the operators who contribute links and hardware are paid from those fees according to how well and how reliably their links perform. The token is therefore a payment and coordination instrument for a physical infrastructure network rather than a governance chip or a wrapped asset.

What holding 2Z looks like in practice

2Z is an SPL token on Solana. That has three consequences a holder should know:

• Every transfer costs a small fee in SOL, never in 2Z, so the wallet needs a little SOL on the same address to move the token at all.
• The first time an address receives 2Z, Solana creates a token account for it, which locks a small rent deposit in SOL; this is normal and is returned if the account is later closed.
• Because the ticker is only two characters, check the token name and mint when adding it, since short tickers attract copycat tokens on Solana.

There is no rebase, no interest-bearing version and no widely used bridged variant to confuse with the original.

Supported networks in Tangem (1): Solana.

Since 2Z and the SOL that pays for its transfers sit under the same key, Tangem holds both in one wallet and signs each send with a tap of the card on the phone, no charging or cables involved. For a token that a validator operator may need to top up or pay out regularly, that combination of one address and quick physical signing is exactly what makes it convenient to keep 2Z there.
