📖 A–Z Glossary of Crypto Payment Terms
A unique string of characters that identifies a wallet on the blockchain. Used to send and receive crypto. Example: TNY...abc (TRON).
A resource on the TRON network used for simple transactions (like TRX transfers). 600 free Bandwidth is provided daily; additional can be staked.
The first and most well-known cryptocurrency. Used as a store of value and for payments, though transaction times and fees can be high.
A container holding a batch of transactions. Blocks are added to the blockchain in sequence, forming a permanent, immutable ledger.
A decentralized, distributed digital ledger that records transactions across a network of computers. The foundation of all cryptocurrencies.
A protocol that enables the transfer of tokens between different blockchains. Example: bridging USDT from Ethereum to TRON.
The process of permanently removing TRX from circulation. On TRON, TRX is burned to pay for transaction fees when Energy is insufficient.
A wallet that stores private keys offline (e.g., hardware wallet or paper wallet). Highly secure for long-term storage.
The process of a transaction being included in a block and validated by the network. More confirmations = greater security and finality.
A wallet where a third party (like an exchange) holds your private keys. Convenient but less secure than self-custody.
A decentralized stablecoin pegged to the USD. Created by MakerDAO and backed by over-collateralized crypto assets.
Decentralized Finance — a set of financial services (lending, borrowing, trading) built on blockchain, without traditional intermediaries.
Delegated Proof of Stake — a consensus mechanism used by TRON. Users vote for Super Representatives who validate transactions and produce blocks.
A computational resource on the TRON blockchain required for smart contract execution. With sufficient Energy, USDT TRC20 transfers cost near-zero fees.
The token standard for fungible tokens on the Ethereum blockchain. USDT and many other tokens are available as ERC20 tokens.
A blockchain platform that supports smart contracts. The second-largest cryptocurrency by market cap, widely used for DeFi and token payments.
A charge paid to the network for processing a transaction. On TRON, fees are paid in Energy (or TRX when Energy is insufficient).
The point at which a transaction is irreversible. On TRON, finality is achieved with 1–2 confirmations (~3–6 seconds).
The process of locking TRX on the TRON network to receive Energy or Bandwidth. Frozen TRX can be unfrozen after a 14-day period.
A fee paid to process transactions on a blockchain (Ethereum). On TRON, the equivalent is Energy and Bandwidth.
A physical device that stores private keys offline. Examples: Ledger, Trezor. The most secure way to store crypto.
A unique alphanumeric string generated from transaction data. Used as a transaction ID to track payments on the blockchain.
A wallet connected to the internet (e.g., mobile app, browser extension). Convenient for frequent transactions but less secure than cold wallets.
Know Your Customer — the process of verifying a user's identity, often required by exchanges and payment processors for compliance.
A secondary protocol built on top of a blockchain to improve scalability and reduce fees. Examples: Lightning Network (Bitcoin), Arbitrum (Ethereum).
A Layer 2 solution for Bitcoin enabling instant, low-cost payments. Ideal for everyday transactions and micro-payments.
The memory pool where pending transactions wait before being included in a block. Transactions are prioritized by fee.
An optional field in a transaction used for additional information. Often required when sending to exchanges to identify the deposit.
A node that validates transactions and adds new blocks to the blockchain (Proof of Work systems like Bitcoin).
A computer that runs blockchain software and participates in the network. Nodes validate transactions and maintain the blockchain.
Transactions that occur outside the main blockchain (e.g., Layer 2). Faster and cheaper, with final settlement on-chain.
Transactions that are recorded directly on the blockchain. More secure and transparent, but can be slower and more expensive.
Payment Finance — the integration of payments with DeFi yields. Enables users to earn interest on stablecoins while using them for payments.
A secret alphanumeric string that proves ownership of a wallet and authorizes transactions. Never share this with anyone.
A consensus mechanism where validators are chosen based on the amount of crypto they stake. Used by TRON, Ethereum (after merge), and others.
A consensus mechanism where miners solve complex puzzles to validate transactions and add blocks. Used by Bitcoin.
A cryptographic key that can be shared publicly. Derived from the private key. Used to generate wallet addresses.
A 12- or 24-word backup phrase that can regenerate all your private keys. Store it securely offline — it's the ultimate backup.
The practice of holding your own private keys, giving you full control over your crypto. Opposite of custodial wallets.
A self-executing program on the blockchain that automatically executes when conditions are met. Powers DeFi, tokens, and programmable payments.
A cryptocurrency pegged to a stable asset like the US dollar. USDT and USDC are the most popular, used widely for payments.
The process of locking TRX on the TRON network to receive Energy or Bandwidth, and to vote for Super Representatives.
Validators on the TRON network, elected by TRX stakers. They produce blocks and maintain the network.
The largest stablecoin, pegged to the US dollar. Available on multiple networks, including TRON (TRC20) and Ethereum (ERC20).
A unique identifier for a blockchain transaction. Used to track and verify payments on explorers like Tronscan or Etherscan.
The token standard for fungible tokens on the TRON blockchain. USDT on TRON uses the TRC20 standard.
A high-performance blockchain designed for payments and decentralized applications. Known for fast finality and low fees.
The official blockchain explorer for TRON. Used to view transactions, blocks, and wallet balances.
A popular wallet for the TRON blockchain. Available as a browser extension and mobile app. Supports TRX, USDT, and other TRC20 tokens.
A node that validates transactions and produces blocks in Proof of Stake systems. On TRON, validators are called Super Representatives.
A software or hardware application that stores private keys and allows users to send, receive, and manage cryptocurrency.
An HTTP callback sent by a payment processor to notify merchants of transaction status changes (e.g., payment confirmed).
