What Is Solana? How Does It Work?

A token trade, a digital dollar payment and an action inside a game can all use the same blockchain while doing very different jobs. Solana (SOL) is a public network for payments and applications. SOL is its native cryptocurrency, used for network fees and participation in securing the system.

A memecoin, a stablecoin and SOL can appear in the same wallet without being the same kind of asset.

Where did Solana begin?

The project traces its origins to Anatoly Yakovenko in 2017. His proposed Proof of History mechanism helped computers establish an order and passage of time between events. The Mainnet Beta network launched in March 2020, turning the project into a network handling real assets.

Its design has continued to change. Alpenglow went live on 21st October 2026, replacing the previous consensus layer. Older descriptions centred on Proof of History therefore do not fully describe how the network agrees on blocks now.

What do people use it for?

Decentralised finance, or DeFi, includes applications for exchanging digital assets. Jupiter is a Solana trading interface and routing service. It can assemble a swap using available trading sources, so the user interacts through a wallet rather than placing every trade manually at separate venues.

Other uses involve digital dollars. Visa announced on 16th December 2025 that Cross River Bank and Lead Bank had begun settling with Visa in USD Coin (USDC) over Solana. Here, Solana is the network carrying settlement, while USDC is the dollar stablecoin being moved. Visa said this did not change the consumer card experience.

Star Atlas’s SAGE Labs provides a different example: a browser strategy game whose actions are recorded on Solana. A game can use the network to track assets and actions, while still depending on its own rules, interface and developers. A game token is not automatically useful outside that game.

Why are memecoins associated with Solana?

Memecoins put internet culture and trading in the same place. BONK began with a group of Solana builders, while dogwifhat (WIF) centres its identity on a dog wearing a hat. The WIF site identifies Solana as the chain it uses.

Their identities are different from SOL’s network role. Creating and exchanging a token uses blockchain infrastructure, but it does not make that token the currency that pays the network’s fees. A memorable character can attract a community without guaranteeing lasting demand or a useful product.

Some projects develop applications around that community. BONK’s site lists BONK Swap alongside other ecosystem products, and identifies some offerings as independently operated or community run. A familiar token brand does not tell you who operates every linked service.

Which memecoins are largest by market value?

At 10:50 UTC on 27th October 2026, the ten largest tokens in CoinGecko’s Solana Meme category were listed below. This is the provider’s category, which includes projects available on other networks too. Its market capitalisation measure multiplies price by circulating supply, the tokens available to the public, rather than all tokens that might eventually exist.

This snapshot ranks market size, not safety or quality. Market capitalisation is also different from the cash available for someone trying to sell; the order can change as prices and circulating supplies change.

How does a Solana app actually run?

A wallet prepares a transaction containing instructions and the signatures that authorise them. Those instructions can call a program, Solana’s term for executable code, to transfer a token or perform an application action.

Validators process the work and agree on the record. Under Alpenglow, they send votes directly to each other and combine agreement into certificates. Proof of History no longer paces block production. SOL holders can also delegate stake to validators, assigning stake to support their participation.

Transaction fees are paid in SOL, with a base fee and an optional priority fee. An app can have separate charges. A token swap therefore involves more than the network fee alone, and a fast network does not remove trading costs or differences in available liquidity.

What can go wrong?

A rug pull is a fraud pattern in which a token’s promoters attract purchasers with promised benefits, then withdraw, sell their tokens or retain the money without delivering those benefits. It can happen around a blockchain token even while the network itself keeps operating. A falling price alone does not establish fraud.

The network, application and asset each carry different risks. Some programs can be upgraded by a designated authority, so who controls that authority matters. A working network can process instructions from an application whose rules or economics disappoint its users.

The network itself has had interruptions. Its report on 6th February 2024 records roughly five hours without consensus progress after a software bug, followed by a coordinated restart. Applications rely on the shared network making progress, regardless of which token they use.

Which SOL are you looking at?

SOL is native to Solana, so ordinary SOL has no token mint address. A mint identifies a token issued through a token program. Wrapped SOL, or WSOL, holds SOL in a token account for applications using token instructions. The standard Token Program’s WSOL mint is So11111111111111111111111111111111111111112.

The Solana Explorer can inspect accounts and transaction signatures. Its network selector matters: mainnet, Devnet and Testnet are different environments, and testing balances are not spendable mainnet SOL.

Official SOL price and centralised trading pages include Kraken, OKX and Bitget. Jupiter provides a route into Solana’s decentralised trading markets. Product access, token support and accepted deposit networks vary by jurisdiction and provider.
