The blockchain ecosystem you see today has come a long way beyond Bitcoin. Throughout the journey, there have been groundbreaking innovations that have created an ecosystem that is self-sustainable and super-efficient. It’s impossible to think of its existence without Altcoins and DeFi tokens. They both serve a crucial purpose in the blockchain environment.
Altcoins came into existence to explore the capabilities of blockchain beyond peer-to-peer payments by introducing features such as smart contracts, decentralized applications, and experiments in privacy, scalability, and governance. With time, these innovations laid the foundation for much of today’s DeFi platforms and Web3 ecosystems. DeFi tokens are the backbone of decentralized financial platforms that transformed traditional services such as lending, borrowing, trading, and asset management, without intermediaries.
This guide explores altcoins and DeFi tokens, clarifies how they differ, and helps you understand why distinguishing between the two matters in the current crypto market.
What are Altcoins?
Altcoins, in a nutshell, are any cryptocurrency that isn’t Bitcoin. Altcoins address Bitcoin’s limitations and introduce entirely fresh blockchain functionalities.
Altcoins were created to expand the capabilities of blockchain technology. Unlike Bitcoin, altcoins aren’t limited to sending or storing assets, they power different blockchain ecosystems. Many modern altcoins use proof-of-stake mechanisms to improve energy efficiency and transaction speed. Some altcoins focus on privacy and security in DeFi, while others focus on scalability or real-world payments.
In short, altcoins aim to solve broader problems and introduce new use cases of the blockchain ecosystem. They’re designed to innovate beyond digital currency and to empower a wide range of blockchain services.
Key Altcoins Shaping The Crypto Ecosystem
With different altcoins solving different problems in the blockchain ecosystem, below is a list of some widely adopted examples.
Ethereum
Ethereum has been the primary enabler for developers to build decentralized applications (dApps) through its smart contract platform. It has played a significant role in the foundation of most of the DeFi, NFT, and Web3 ecosystems. With one of the largest developer communities and a sophisticated infrastructure, Ethereum has established itself as one of the most influential altcoins in the crypto space.
Native Currency: ETH (Used for transaction fees, staking to secure the network, and interacting with applications)
Cardano
Cardano was developed using peer-reviewed research and is a proof-of-stake blockchain platform focused on security and scalability. It is widely considered one of the most energy-efficient blockchains that supports smart contracts and dApps. Its emphasis on long-term sustainability has helped Cardano (ADA) build a loyal user base of developers and investors.
Native Currency: ADA (Used for transactions, staking, and governance)
Solana
Solana is a high-performance blockchain known for fast, low-cost transactions. It is widely used for DeFi applications, NFTs, and Web3 projects that require high processing speed. It introduced a unique Proof-of-History system that functions as a cryptographic clock to automatically confirm transactions. This method can process thousands of transactions in seconds. While Solana has faced network stability challenges in its early days, its speed and growing ecosystem continue to drive large-scale adoption.
Native Currency: SOL (Used for transaction fees, staking to secure the network, and participating in governance)
Binance Coin
Born through an initial exchange offering (IEO), Binance Coin was initially created primarily to offer trading-fee discounts on the Binance exchange. Now BNB is used on the BNB Chain for transaction fees, staking, and DeFi applications. Despite its performance being closely tied to Binance’s ecosystem and regulatory environment, its utility on the exchange has helped it build a strong user base.
Native Currency: BNB (Used for transaction fees, staking, and DeFi applications)
Polkadot
Polkadot is an interoperability-focused multi-chain network that allows different blockchains to communicate and share security. While most blockchains operate independently, Polkadot serves as a central hub that connects specialized blockchains, called parachains, enabling them to share data and assets securely. Each parachain can be customized for specific use cases such as DeFi, NFTs, or gaming. Relay Chain is the core of Polkadot’s main network to which every parachain is connected.
Native Currency: DOT (used for governance, staking, and securing the network)
Stellar (XLM)
Stellar is a payment-focused blockchain network built for fast, low-cost cross-border payments and asset transfers. Users and businesses can transfer money and issue digital assets efficiently worldwide. Stellar’s emphasis on financial accessibility has made it a notable altcoin in the payments and remittance space.
Native Currency: XLM (used for transaction fees, maintaining minimum balance, and acts as a bridge asset to help move value efficiently between different currencies)

What are DeFi Tokens?
DeFi tokens are associated with blockchain-based platforms that offer financial services without banks or any centralized intermediaries.
Applications powered by DeFi tokens enable users to:
- Lend and borrow crypto assets
- Trade assets on decentralized exchanges
- Participate in governance decisions
- Earn interest by staking or investing in liquidity pools
Unlike most Altcoins that serve as a blockchain’s main currency, DeFi tokens are typically governance or utility tokens tied to a specific protocol rather than serving as the native currency of a blockchain. These platforms have self-executing programs that automatically provide financial services such as trading and lending. DeFi tokens are used on these platforms to grant users voting rights, reward participation in liquidity pools, and help keep the network secure.
All DeFi tokens are technically Altcoins, but not all Altcoins can be DeFi tokens. The difference is that Altcoins support blockchain infrastructure while DeFi tokens are specific to decentralized financial operations.
Popular DeFi Tokens and What They Do
From trading and lending to yield farming, DeFi tokens come in many forms. Below are some of the most widely used protocols that have been instrumental in shaping DeFi.
Uniswap (UNI)
Uniswap is a decentralized exchange that allows you to swap cryptocurrencies directly from your wallet without third-party involvement. An automated market maker (AMM) model allows you to trade directly with liquidity pools through smart contracts rather than with other traders. These pools are created by users called liquidity providers. As one of the largest decentralized exchanges by trading volume, Uniswap plays a central role in the DeFi ecosystem.
Governance Token: UNI (allows holders to vote on protocol upgrades and ecosystem decisions)
Aave (AAVE)
Aave is a decentralized lending and borrowing platform. It allows users to earn interest by lending their crypto assets into liquidity pools. You can also borrow assets by putting up your existing crypto as collateral. Interest rates are set algorithmically by smart contracts based on supply and demand. Aave is widely used in DeFi due to its innovative features and multi-chain support.
Governance Token: AAVE (used for governance and staking)
MakerDAO (MKR)
MakerDAO is a decentralized platform that plays a critical role in decentralized lending and stablecoin infrastructure. MakerDAO lets you mint DAI by providing crypto as collateral. DAI is a stablecoin, and its price lingers around the US dollar. First, you will lock your collateral in the MakerDAO smart contract, then mint DAI via overcollateralization.
Over your collateral, there’s also a stability fee that accumulates over time. To get your collateral back, you must repay the same amount of DAI borrowed, plus the stability fee. In case of a sudden price drop of the assets you’ve put up as collateral, the platform is entitled to sell them to repay the DAI.
Governance Token: MKR (allows holders to manage risk parameters, collateral types, and protocol upgrades)
Synthetix (SNX)
Synthetix is a DeFi protocol that lets users create and trade synthetic assets that mirror real-world assets, like currencies, commodities, and stocks. Instead of buying the real asset, you mint its synthetic version(tokens) by putting up your SNX tokens as collateral.
Minted assets mirror the price of the underlying real asset; for example, sBTC will mirror the BTC price, and sETH will mirror the ETH price in the real market. If you minted sETH and its price goes up, you will make a profit. All SNX stakers share a single global debt pool: when traders profit, stakers absorb the debt; when traders lose, stakers benefit.
Governance Token: SNX (used as collateral and for governance)
SushiSwap (SUSHI)
SushiSwap is a decentralized exchange built on Uniswap’s original framework and has since become a broader DeFi platform. It offers token swaps, yield farming, lending, and staking services across multiple blockchains.
What sets it apart from UniSwap is that the trading fee is shared with SUSHI stakers and liquidity providers. Unlike Uniswap, it doesn’t limit itself to token swaps; it also offers lending, yield tools, and bridges.
Governance Token: SUSHI (used for rewarding liquidity providers and enabling community-driven decision-making)
Yearn Finance (YFI)
Yearn Finance is a DeFi platform that simplifies yield farming. It automatically moves your crypto across different lending platforms to optimize returns. You don’t have to chase interest manually; you only need to deposit assets into vaults, and the platform does the rest. The earned yield is reinvested in the vault. Yearn Finance helps reduce complexity for users seeking passive income.
Governance Token: YFI (provides control to holders over protocol strategies and upgrades)
Chainlink (LINK)
Chainlink is a decentralized oracle network that doesn’t directly provide a use case to traders but has a significant role in the blockchain ecosystem. Blockchains are closed systems and cannot access external information. Chainlink bridges this gap by providing real-world data such as price feeds, interest rates, and event outcomes to smart contracts. Independent Chainlink nodes pull data from multiple sources, such as exchanges, data providers, and APIs.
Governance Token: LINK (used for paying node operators and incentivizing accurate data delivery)
Conclusion
Altcoins and DeFi tokens are two critical pillars of the modern crypto ecosystem. Altcoins are pushing the boundaries of blockchain capabilities, while DeFi tokens are advancing decentralized financial services. They serve different roles but fuel innovation across Web3. Understanding how both function will help you make informed decisions and explore new opportunities.
Whether you choose to participate in staking or you lend/borrow crypto assets to trade, both demand proper accounting to stay compliant with tax regulations. KoinX helps you track transactions and simplify crypto tax reporting, allowing you to build a portfolio with confidence.
