The first major stableswap AMM on Solana, using a Curve-style invariant for efficient swaps between same-peg assets such as stablecoins and wrapped token variants. Saber reached peak TVL of over $4B in 2021, becoming the largest protocol on Solana by TVL at that time. The protocol pioneered the stableswap model on Solana but declined significantly by 2023 as liquidity migrated to newer platforms.

Use the quick analogy first so the term is easier to reason about when you meet it in code, docs, or prompts.
Think of it as a building block that connects one definition to the larger Solana system around it.
Place the term inside its Solana layer so the definition is easier to reason about.
Teams, protocols, tools, and the wider Solana product landscape.
Turn the term from vocabulary into something operational for product and engineering work.
This term unlocks adjacent concepts quickly, so it works best when you treat it as a junction instead of an isolated definition.

A protocol that enables token swaps using algorithmic pricing against pooled liquidity instead of matching individual buyers and sellers. AMMs use mathematical formulas (typically constant product x*y=k) to determine prices based on the ratio of tokens in a liquidity pool. On Solana, major AMMs include Raydium, Orca, and Meteora.
A token pegged to a stable asset, typically the US dollar. Major stablecoins on Solana include USDC (Circle, natively minted), USDT (Tether), and UXD (algorithmic). Stablecoins are critical DeFi primitives used as trading pairs, lending collateral, and yield farming. USDC on Solana uses the SPL Token program with freeze authority retained by Circle.
A smart-contract-held reserve of two or more tokens that enables trading via an AMM. Users deposit token pairs in specified ratios to become liquidity providers and earn trading fees. Pools are identified by their token pair and fee tier. Pool depth (total value locked) determines price impact for trades.
These are the next concepts worth opening if you want this term to make more sense inside a real Solana workflow.
These entries are easy to mix up when you are reading quickly, prompting an LLM, or onboarding into a new layer of Solana.
Solana's self-styled ambassador dog memecoin, launched in April 2021 as one of the earliest memecoins on the network. The SAMO community positions the project as an ecosystem education and adoption vehicle, hosting events, producing content, and onboarding new users to Solana. SAMO maintains one of the longest-running memecoin communities on Solana with a focus on positive ecosystem contribution.
A Solana-native messaging and payments token enabling wallet-to-wallet transfers through a simplified mobile interface focused on consumer accessibility. Send aims to make crypto payments as intuitive as messaging apps by combining a social graph with payment functionality, targeting mainstream users who want to send and receive tokens without navigating complex DeFi interfaces.
An early Solana liquid staking protocol that used algorithmic stake distribution to promote validator decentralization. Socean issued scnSOL as its liquid staking token and pioneered automated delegation strategies on Solana. The protocol merged into the Sanctum ecosystem in 2024, with its liquid staking functionality absorbed into Sanctum's unified LST infrastructure.

The most popular Solana wallet, available as a browser extension and mobile app with multi-chain support (Solana, Ethereum, Polygon, Bitcoin). Phantom provides token swaps, NFT management, staking, and a built-in dApp browser. Known for its clean UX and rapid feature adoption, it has become the default entry point for most Solana users and consistently ranks among the top crypto wallets by active users.
A Solana-native wallet offering browser extension, mobile, and web interfaces with deep staking integration, hardware wallet support (Ledger), and a built-in dApp browser. Solflare was one of the first Solana wallets and provides advanced features like stake account management, token metadata display, and priority fee controls. It supports the Solana Wallet Standard for seamless dApp connectivity.
A multi-chain wallet developed by Coral (the team behind xNFT protocol) that combines MPC and self-custody models. Backpack pioneered executable NFTs (xNFTs) that embed full applications inside NFTs, enabling a decentralized app store experience within the wallet. It supports Solana, Ethereum, and other chains with a focus on developer extensibility and programmable wallet experiences.
A regulated cryptocurrency exchange built by the same team behind Backpack Wallet (Coral). Licensed in multiple jurisdictions, it offers spot and perpetual futures trading with a focus on the Solana ecosystem. Backpack Exchange integrates tightly with the Backpack Wallet for seamless fund transfers and aims to bridge the gap between centralized exchange liquidity and self-custodial wallet experiences.
