Multisig requires multiple signatures to execute a transaction (e.g. 2-of-3). Even if one key is stolen, funds cannot be moved alone, making it ideal for teams and high-value assets. On Solana, Squads is widely used.
Solana transaction fees are two-tiered: a base fee (5,000 lamports = 0.000005 SOL per signature) and an optional priority fee. Half of the base fee is burned and half goes to the validator; a priority fee is added only during network congestion.
Solana transactions fail mainly due to insufficient balance, slippage exceeded, drops from congestion, or an insufficient priority fee. Keep some SOL for fees and, during congestion, raise the priority fee and resubmit. Even on failure, your assets generally don't move.
Solana is integrating with major payment and finance companies: Visa's USDC settlement, PayPal's PYUSD issuance (May 2024), and Shopify's Solana Pay support (August 2023) all point to growing practical adoption.
When FTX collapsed in November 2022, fears over FTX/Alameda's large SOL holdings sent SOL from around $30 into the single digits, hitting roughly $8 in December. But the chain survived and recovered to near its all-time high by 2025.
Your seed phrase is the one and only key to all your assets. Write it down offline on paper, never enter it except when restoring a legitimate wallet, and never save it in photos, the cloud, or chat. Official support will never ask for it.
If a SOL transfer isn't arriving, first check the transaction ID in a block explorer. Most cases are delays, a wrong address, or an exchange credit lag — not a lost transfer — and a failed transaction means your assets never moved. Misdirected transfers can't be recovered.
A Ledger is a hardware wallet that isolates private keys inside the device, making it well suited to long-term SOL storage. Install the Solana app in Ledger Live, connect it to Phantom or Solflare, and physically approve every transfer; keeping your seed phrase safe matters most.
Solana is a permissionless network anyone can join, and no single validator holds a majority (Nakamoto coefficient of about 20). But with a shrinking validator count and top-heavy concentration, the fair view is that decentralization is a work in progress.
Airdrops are free token distributions; JUP and JTO are the best-known on Solana, with eligibility based on past on-chain activity. Verify via official primary sources — seed-phrase requests, deposit demands, and fake checkers are 100% scams.
Solflare is a leading Solana-focused wallet. The keys to safety are installing it from the official source and storing your recovery phrase offline. It supports holding, sending/receiving, staking, and dApp connections.
On Solana, the delegate authority you grant to dApps can be revoked later. Review the list in Phantom's settings or a trusted revoke tool and remove unneeded or suspicious approvals regularly.
DeFi is a set of middleman-free financial apps, and Solana offers low fees and high speed. To start: set up a wallet → add a little SOL/USDC → swap on Jupiter. Understand contract bugs, scams, and volatility, and start small.
On Solana, same-name/same-logo fake tokens and fake sites are common. Verify tokens against the official mint address and sites against the exact official URL, and don't touch tokens that arrive unsolicited.
SOL has no halving. Issuance follows a disinflation schedule — 8% initial annual inflation, declining 15% per year toward a terminal ~1.5% — with about 95% of new SOL going to staking rewards and no fixed supply cap.
You can buy SOL for just a few dollars. Starting small lets you get comfortable buying, sending, and storing before increasing the amount — but watch fee ratios, overbuying, and high-yield scams.
SOL is the base currency of a general-purpose chain, while XRP is the token of the transfer- and settlement-focused XRP Ledger. Solana uses PoS + PoH; XRP uses consensus among trusted validators. Their goals differ, so choose by use case rather than ranking one above the other.
Solana represents everything as an account. Because program code and data live in separate accounts, transactions can be processed in parallel, making the network fast — and keeping each account alive requires rent.
pump.fun is a Solana launchpad (live since January 2024) that lets anyone create a meme coin, with prices set automatically by a bonding curve. The culture is huge, but most tokens fall to near-zero value and the space is full of scams.
A Solana Hacker House is a developer- and builder-focused gathering held in cities worldwide. Tied to hackathons, it's a place to learn, network, and build — distinct in scale and purpose from the annual Breakpoint conference.
The Solana Seeker is Solana Mobile's second Web3 phone (the Saga successor). It started shipping in August 2025, was priced around $450–$500 at pre-order, and ships with a Seed Vault and dApp Store.
DePIN uses token rewards to decentralize real-world infrastructure like connectivity, mapping, and GPU compute. Solana's low fees and speed make it a natural fit, with Helium migrating in 2023 and Hivemapper and Render joining too.
USDC is a US dollar 1:1 stablecoin issued by Circle. On Solana it's a native SPL token offering low fees and fast transfers, serving as a base currency for payments and DeFi—though issuer and regulatory risks are not zero.
A compressed NFT (cNFT) is a Solana NFT that uses state compression to slash minting costs — only a summary (a Merkle tree) is recorded on-chain, making mass minting orders of magnitude cheaper. They're minted with Metaplex Bubblegum.
A priority fee is an optional fee that gets your Solana transaction processed first during congestion. You set it in micro-lamports per compute unit (priority fee = CU price × CU limit), the default is 0, and all of it goes to validators.
Jito is Solana infrastructure built on three pillars: the Jito-Solana client, bundles and tips, and the JitoSOL liquid staking token. It handles MEV (value from transaction ordering) via an auction and returns part of the revenue to stakers.
Anatoly Yakovenko is a co-founder of Solana and the inventor of Proof of History. His roughly 13 years of distributed-systems experience at Qualcomm led him to the idea of proving time on a blockchain, which he published in a 2017 whitepaper.
Both Phantom and Solflare are leading Solana wallets with solid core features. Phantom favors ease of use and multichain support; Solflare offers deeper Solana-specific features like staking. Security depends on how you use it.
A CEX is a company-run exchange with fiat deposits and account custody; a DEX connects your wallet to swap directly via smart contracts. Buy your first SOL on a CEX, then swap tokens on Solana with a DEX.
A wallet drainer is a malicious script that gets you to sign once on a fake site and steals your assets. On Solana the focus is direct transfers and delegate abuse; reading each signature and using a hardware wallet are the best defenses.
Rent is the minimum balance that keeps a Solana account alive. It's not a fee that vanishes — it's a deposit that's returned when you close the account, and a standard SPL token account needs about 0.002 SOL.
