What is TRC-20 Token Standard

TRC-20 is the token standard for fungible tokens on the Tron blockchain — Tron's equivalent of Ethereum's ERC-20 standard. TRC-20 tokens operate through smart contracts on the Tron Virtual Machine (TVM) and share functional similarities with ERC-20 tokens while running on a separate, high-throughput blockchain. TRON'S TOKEN STANDARDS Tron supports three token types: TRX: The native currency used for transaction fees and staking. TRC-10: A basic token standard built into the Tron protocol without smart contracts — limited functionality, lower fees. TRC-20: Smart contract-based standard equivalent to ERC-20 — supports complex token logic, DeFi interactions, and broad exchange compatibility. WHY TRC-20 USDT DOMINATES GLOBALLY Tether has issued USDT on Tron, and it has become the most widely used USDT version globally by transaction count. The reasons are practical: Near-zero fees: TRC-20 USDT transfers cost approximately $0.001-0.01 (versus $1-20+ for ERC-20 USDT on Ethereum mainnet during congestion). Fast confirmation: Tron achieves 3-5 second finality at ~2,000 TPS. Wide exchange support: Most global exchanges accept TRC-20 USDT deposits and withdrawals. This makes TRC-20 USDT the dominant stablecoin rail for Asian OTC trading, P2P exchange, and emerging market remittances. TRON NETWORK RISKS Centralisation: Tron has only 27 Super Representative validators selected by TRX vote — extremely centralised compared to Ethereum's 500,000+ validators. Justin Sun controversy: Tron's founder has faced SEC fraud and market manipulation charges (settled 2024). Network concentration: The majority of Tron activity is USDT transfers, creating dependency on Tether's continued use of the network.

Terms in addition to the TRC-20 Token Standard

Blockchain

A blockchain is a subset of a distributed database. The Bitcoin inventors originally prototyped the system in 2008. This modern database is made up of separate blocks that are connected together in a chronological chain. Blockchains may be used to store a wide range of data types. It has mostly been utilized as a public ledger for bitcoin transactions to date. A peer-to-peer network comprised of independent nodes uses a consensus process to ensure the blockchain's security and legitimacy. Each node in the network keeps a public and immutable copy of the data.

2 Factor Authentication (2FA)

2 Factor Authentication is a security measure with two layers. It is used by the majority of cryptocurrency exchanges. To log in, you must provide not only a password, but also a code obtained, for example, from the Google authenticator.

Airdrop

An airdrop is a method of distributing coins. End users can typically obtain coins for free or in exchange for doing a small task, such as subscribing to a newsletter, sending a tweet, or inviting others via a personal affiliate link. Cryptocurrency airdrops — the act of depositing cryptocurrency into public crypto wallets — are utilized as a marketing, liquidity creation, and network bootstrapping technique for many different types of blockchain initiatives.

Altcoin

Altcoin - "alternative coin" - is any kind of digital currency other than Bitcoin. Since the launch of Bitcoin, the world's first digital currency, many altcoins (as well as supporting blockchains) have been created. Altcoin digital currencies share many similarities to Bitcoin, but consistently and have significant differences. There are about 20,000 altcoins, and this number is expected to grow significantly in the coming years. Altcoins often develop Bitcoin features. Ethereum, currently the most widely used blockchain, supports digital contracts and separate applications where Bitcoin does not. Altcoins are also often created to cater to the needs of different users. The Litecoin blockchain, for example, can process payments quarterly for the duration of Bitcoin.

Cold Storage

Cold storage is the way to store cryptocurrency offline. The word refers to the use of offline wallets that are not connected to the internet. Cold storage is the most secure way to keep cryptocurrencies since an offline currency becomes less likely to be hacked and stolen. Paper wallets, printed renditions of private keys, and offline hardware and software wallets are all examples of cold storage.
