1. Wallet
A software or hardware tool that stores the keys needed to access your crypto on a blockchain. Wallets do not actually hold coins — the coins live on the blockchain; the wallet just holds the credentials to prove ownership.
Crypto is full of jargon that sounds intimidating but is usually straightforward once someone explains it clearly. This glossary covers 50 of the most common terms — from basic wallet concepts to Solana-specific mechanics — in plain English, with no hype and no agenda.
Everything on this page is written for educational purposes. Cryptocurrency markets are highly volatile and largely unregulated. Nothing here constitutes investment advice, a recommendation to buy or sell any asset, or a prediction of future prices. Always do your own research (DYOR), consult a licensed financial adviser if needed, and never invest more than you can afford to lose entirely. Verify all on-chain data yourself using reputable block explorers.
One of the best protections against crypto scams is simply understanding what the words mean. When someone asks you to "send SOL to claim your airdrop" or promises "guaranteed 10x returns," a solid vocabulary is what helps you recognise that something is off.
The terms below are grouped loosely by theme. Each entry is deliberately short — one or two sentences — because the goal is quick comprehension, not a textbook. Where a TrustTails tool can help you verify something on-chain yourself, we link to it. Use those tools; do not take anyone's word for it.

Understanding how ownership works in crypto is the single most important thing a beginner can learn. These terms cover it.
A software or hardware tool that stores the keys needed to access your crypto on a blockchain. Wallets do not actually hold coins — the coins live on the blockchain; the wallet just holds the credentials to prove ownership.
A secret string of characters that proves you own a wallet address. Anyone who knows your private key can move every asset in that wallet — guard it like a password to your entire bank account.
The publicly shareable identifier for your wallet — like an email address or bank account number. You can give this to anyone who wants to send you crypto; it reveals nothing sensitive.
A human-readable list of 12 or 24 words that can regenerate your private key. Losing this phrase means permanent loss of access; sharing it means giving away full control of your wallet. Never type it into any website.
A custodial wallet (like most exchanges) holds your keys on your behalf — you trust a company. A non-custodial wallet (like Phantom on Solana) gives you direct key control. "Not your keys, not your coins" refers to this distinction.
A physical device (like a Ledger or Trezor) that stores private keys offline, making them inaccessible to internet-based attacks. Considered the gold standard for long-term self-custody security.
These foundational terms explain the infrastructure that all cryptocurrencies are built on.
A shared database of transactions grouped into "blocks" that are chained together cryptographically. Once data is written to a block and enough participants confirm it, it becomes effectively permanent and tamper-evident.
A computer that participates in a blockchain network by storing a copy of the ledger and verifying transactions. More nodes generally means a more decentralised and resilient network.
The method a blockchain uses to get all participants to agree on the correct state of the ledger. The two most common are Proof of Work (PoW) and Proof of Stake (PoS).
A consensus method where computers race to solve complex puzzles to validate transactions (Bitcoin uses this). It is energy-intensive by design, as that energy cost is what makes attacking the network expensive.
A consensus method where validators lock up (stake) their own crypto as collateral in exchange for the right to validate transactions. Ethereum moved to PoS in 2022; Solana uses a variant called Proof of History combined with PoS.
Code stored on a blockchain that executes automatically when predefined conditions are met, without needing a middleman. Smart contracts power decentralised exchanges, NFT mints, lending protocols, and more.
Any action recorded on the blockchain — sending tokens, swapping on a DEX, minting an NFT, or interacting with a smart contract. Every transaction is public and permanently visible on a block explorer.
A website that lets anyone search and verify data on a public blockchain — transactions, wallet balances, token details, and more. For Solana, Solscan.io is one of the most widely used explorers. You can verify TrustTails on-chain at Solscan.
These terms explain the specific mechanics behind the tokens you encounter — including concepts that are directly verifiable on-chain.
A coin (like SOL or BTC) is the native asset of its own blockchain. A token is created on top of an existing blockchain using that chain's standards — for example, TrustTails (TAIL) is a token built on the Solana blockchain.
The Solana Program Library (SPL) token standard is Solana's equivalent of Ethereum's ERC-20. Any fungible token created on Solana — including TrustTails (TAIL) — is technically an SPL token. You can verify an SPL token's details using the TrustTails token checker.
The maximum number of tokens that will ever exist for a given project. TrustTails has a fixed total supply of 1,000,000,000 (one billion) TAIL tokens. This number is verifiable on-chain and cannot be changed because mint authority has been revoked.
The portion of the total supply that is currently in circulation — not locked, burned, or reserved. Market cap calculations usually reference circulating supply rather than total supply.
The permission to create (mint) new tokens. When mint authority is revoked, no additional tokens can ever be created — the supply is permanently capped. TrustTails has had its mint authority revoked, which is verifiable on Solscan. You can use the token checker tool to confirm this.
The permission to freeze token accounts, preventing specific holders from transferring their tokens. When freeze authority is revoked, nobody — not even the project team — can freeze your tokens. TrustTails has had its freeze authority revoked, verifiable on-chain.
Market capitalisation — calculated as circulating supply multiplied by the current price. It gives a rough sense of a token's total market value. A very small market cap can mean a project is early-stage or illiquid; it does not predict future performance.
The permanent destruction of tokens by sending them to an address nobody controls (a "burn address"). This removes them from circulation forever. Burns are sometimes used to reduce supply, though their effect on price is not guaranteed.
Once you understand ownership, the next layer is how tokens are bought, sold, and exchanged — and the risks involved.
A company-run exchange like Coinbase, Binance, or Kraken where you create an account and the exchange holds custody of your assets. Convenient but requires trust in the operator; historical exchange collapses have resulted in users losing funds.
A protocol that lets users swap tokens directly from their own wallets using smart contracts — no sign-up, no identity checks, no custodian. Examples on Solana include Raydium and Orca. Trades happen on-chain and are publicly visible.
The smart-contract mechanism most DEXes use to determine prices. Instead of a traditional order book, AMMs use liquidity pools and a mathematical formula (often x × y = k) to set the price based on the ratio of two tokens in a pool.
A smart contract holding a pair of tokens (e.g. TAIL/SOL) deposited by users called liquidity providers. These pools enable DEX trading. Without a liquidity pool, a token cannot be traded on a DEX regardless of how much interest there is.
The difference between the price you expected when placing a trade and the price you actually received. Slippage occurs in low-liquidity pools or when a large order moves the market. Most DEX interfaces let you set a maximum slippage tolerance.
How easily an asset can be bought or sold without significantly changing its price. High liquidity means large trades can happen with minimal slippage; low liquidity means even small trades can cause large price moves. Very new or small tokens are typically low-liquidity.
The collective term for financial services — trading, lending, borrowing, earning yield — that run on blockchains via smart contracts rather than banks. DeFi carries unique risks including smart contract bugs and protocol failures.
The fee paid to validators who process and confirm your transaction. On Ethereum, this fee is called "gas"; on Solana, the equivalent unit is lamports (one SOL = one billion lamports). Solana fees are typically a fraction of a cent, which is one reason it is popular for small-token projects.
This is the most important group. Understanding these terms could save you from significant losses.
A scam where project creators build apparent legitimacy, attract buyers, then suddenly drain the liquidity pool or sell their own tokens — leaving other holders with worthless assets. Revoking mint and freeze authority, publishing tokenomics transparently, and locking liquidity are common (though not foolproof) indicators that a team is not planning to rug.
A reminder that you — not a content creator, influencer, or community member — are responsible for verifying information before acting on it. DYOR means checking on-chain data, reading official documentation, understanding the risks, and making your own decision.
A scheme where coordinated actors artificially inflate a token's price through hype or coordinated buying, then sell their holdings into the elevated price — leaving later buyers with losses. Pump-and-dump activity is common in low-cap tokens and is generally illegal in regulated markets.
A scam where someone impersonates a legitimate project, exchange, or wallet provider to trick you into revealing your seed phrase or private key. Phishing attempts often arrive via DM, email, or fake websites. TrustTails will never DM you first or ask for your seed phrase.
A token designed so that you can buy it but cannot sell it — the smart contract blocks sells for everyone except the creators. Always check whether a token can be sold before buying. On Solana, third-party analysis tools can check for honeypot-like restrictions.
The anxious feeling that a price is rising and you will miss gains if you do not buy immediately. FOMO is deliberately triggered by hype campaigns and is one of the leading causes of impulsive investment decisions. Calm, researched decisions consistently outperform reactive ones.
If you are exploring tokens on Solana, these terms come up constantly. Understanding them helps you verify what you read.
A high-performance blockchain known for fast transaction speeds (typically under a second) and very low fees (often below $0.001). SOL is the native coin used to pay transaction fees and for staking. TrustTails (TAIL) is built on Solana.
The smallest unit of SOL, named after Leslie Lamport. One SOL equals one billion lamports. When Solana transaction fees are described as "fractional cent" amounts, they are being paid in lamports.
Solana's unique mechanism that creates a historical record proving that an event occurred at a specific point in time. PoH acts like a cryptographic clock, allowing validators to agree on the order of transactions without coordinating with each other — contributing to Solana's speed.
On Solana, each token you hold requires a dedicated token account in your wallet. These accounts have a small SOL "rent" cost (usually around 0.002 SOL) to create. This is a normal part of how Solana manages on-chain data.
One of the most widely used browser-extension and mobile wallets for Solana. Phantom is non-custodial — your seed phrase never leaves your device. It is often used to hold SPL tokens and interact with Solana DeFi protocols and NFT platforms.
A computer that participates in Solana's consensus process by processing transactions and voting on the state of the blockchain. Validators stake SOL and are selected to produce blocks based on their stake weight.
A few more terms that appear frequently when reading about the crypto ecosystem.
A token that represents unique ownership of a specific digital or physical asset — unlike fungible tokens where every unit is identical. NFTs are commonly used for digital art, collectibles, and event tickets. Being non-fungible means no two NFTs in a collection are interchangeable.
The free distribution of tokens to wallet addresses — usually to reward early community members, early users of a protocol, or holders of a related token. Legitimate airdrops do not require you to send money first, connect to unknown sites, or share your seed phrase. Scammers frequently impersonate airdrops.
Locking tokens in a protocol or blockchain to help secure the network and, in return, earning rewards. Staking mechanics, lock-up periods, and reward rates vary enormously between projects. Staking always carries the risk of the underlying token's value changing.
Identity verification procedures required by regulated exchanges and financial services. A centralised exchange may ask you to upload ID documents before allowing larger transactions. Decentralised protocols generally do not perform KYC, though regulation in this area is evolving.
On-chain means data or logic is stored and executed on the blockchain itself — transparent and permanent. Off-chain means data is stored elsewhere (a server, a database). Many projects store NFT images off-chain, which introduces dependency on that external storage remaining available.
The distribution of control across many participants rather than a single entity. A more decentralised network has no single point of failure or control. Most blockchains exist on a spectrum from "more decentralised" to "less decentralised" — honest assessment of this is part of understanding any project.
A document published by a crypto project explaining its purpose, technology, token economics, and roadmap. Reading a whitepaper — and checking whether its claims are verifiable — is a core part of DYOR. The absence of a whitepaper is a risk indicator.
A timeline that controls when team members, investors, or advisors can access their token allocations. Vesting schedules (e.g. "1 year cliff, then linear release over 3 years") are designed to align long-term incentives. A project with no vesting on team tokens carries a higher risk of early selling.
Now that the terminology is clearer, here is how TrustTails maps to these concepts — stated factually, not as a sales pitch.
TrustTails (TAIL) is a Solana SPL token. This means it can be held in any Solana-compatible wallet (like Phantom), checked on Solscan, and — when a pool is created — traded on Solana DEXes. No special app is required to hold it.
The 1,000,000,000 TAIL supply is fixed because mint authority is revoked — nobody can create more. Freeze authority is also revoked — nobody can freeze your tokens. Both facts are verifiable on Solscan right now, before buying a single token.
TrustTails is currently pre-launch — it is not yet available to buy. It is a small, early-stage community token. This glossary exists not to push you toward buying, but because an informed community is better for everyone. Make your own judgment when the time comes.
In the broader crypto landscape, TrustTails sits alongside thousands of other small-cap community tokens — on Solana alone there are tens of thousands of SPL tokens. Well-established projects like Bitcoin (BTC), Ethereum (ETH), and Solana (SOL) have years of track record, institutional infrastructure, and deep liquidity that new tokens do not have.
We mention this not to disparage TrustTails, but because honesty is central to what this project is. Every new token carries significant risk. Verify on-chain, join the community to ask questions, and make your own informed decisions. If you find this educational approach refreshing, that is what the project is going for.
Common questions about crypto terminology and how to apply it safely.
For small amounts you are actively using, a reputable non-custodial software wallet like Phantom (for Solana) is commonly used. For larger holdings intended for long-term storage, a hardware wallet is considered significantly more secure because the private keys never touch an internet-connected device. Whichever option you choose, write your seed phrase on paper and store it somewhere physically secure — never digitally. No wallet, software or hardware, guarantees against all loss — user error, lost seed phrases, and scams are all real risks.
It is meaningful and verifiable — but context matters. Revoking mint authority means the on-chain permission to create new tokens no longer exists, so the supply cannot be inflated. This is a legitimate, auditable fact. However, it is one characteristic among many — a project can revoke mint authority and still have other issues (team tokens, liquidity risks, etc.). You can verify it yourself on Solscan without trusting anyone's word.
Bitcoin (BTC) is the original cryptocurrency, designed primarily as a store of value and decentralised payment system. Ethereum (ETH) introduced programmable smart contracts, enabling DeFi and NFTs. Solana (SOL) is a newer layer-1 blockchain focused on speed and low fees, also supporting smart contracts. TrustTails (TAIL) is an SPL token built on top of Solana — not its own blockchain. This makes it categorically different from BTC, ETH, or SOL, which are native coins of their own blockchains. TAIL carries the risks of both the Solana ecosystem and the additional risks of being a small, early-stage community token. This is not a comparison of merit — it is a factual description of what each is.
Always start from this official website — trusttails.io — and follow the links on the footer or community page. The official channels are: X at @trusttailscoin, Telegram community at t.me/TrustTailsCommunity, and official announcements at t.me/TrustTailsOfficial. Do not trust links from DMs, even if the username looks official. Scammers regularly clone channel names with minor typos. When in doubt, verify the channel URL character by character against what is published on this website.
Pre-launch means TrustTails tokens are not yet available for public purchase — there is no live liquidity pool, no presale, and no way to buy TAIL at this time. If anyone contacts you claiming to offer TAIL tokens for sale right now, that is a scam. When the project launches, announcements will come through the official channels listed above, and the contract address to use will be the one published on this site: 4NoNV3jSYLRbUtVWSTK5XdkpuvRzGpMCmfZSBKMuk6Rc. Always verify this address on Solscan before any transaction.
No. Nothing on this page is investment advice. The cryptocurrencies mentioned — Bitcoin, Ethereum, Solana, and others — are referenced for educational context only. No cryptocurrency is recommended here. Every asset mentioned carries its own risks. The same applies to TrustTails: it is presented factually as a small pre-launch community token, not as a good or recommended investment. Always do your own research, understand the risks, and if needed, speak to a licensed financial adviser.
