Decentralized finance (DeFi) aims to transform financial services through blockchain-based applications and protocols. One essential component powering DeFi’s explosive growth has been the stablecoin Tether (USDT).
In this comprehensive guide, we unravel Tether’s multi-faceted role across DeFi and why it has impacted the crypto market.
Stablecoins like Tether aim to maintain a stable value, typically pegged 1:1 to a fiat currency like the US dollar. This makes them helpful in minimizing volatility when interacting with decentralized apps and protocols.
Tether, in particular, has become the most widely used stablecoin in crypto, with a market cap of over $96 billion as of early 2024.
With its stable value and liquidity, Tether serves several functions in DeFi:

Decentralized finance emerged in 2017-2018 as a set of platforms and protocols built on public blockchains like Ethereum. DeFi aims to recreate traditional financial services, including lending, derivatives, asset management, etc., in a decentralized architecture.
DeFi has exploded since early 2020, with the total value locked (TVL) in DeFi protocols surging from around $1 billion to over $250 billion as of early 2024. Top DeFi platforms like Aave, Uniswap, and Compound each have billions in assets supplied by users.
Several interrelated factors have spurred DeFi’s meteoric growth:
As DeFi grows, stablecoins like Tether are increasingly critical as the “rails” moving assets between protocols and users.

Most decentralized exchanges (DEXs) like Uniswap primarily offer trading between volatile crypto assets like ETH and BTC. Tether provides a USD proxy to create stable trading pairs like ETH/USDT. This allows traders to move in and out of positions without returning to fiat and provides an easy calculation for profit/loss.
Stable pairs also allow the creation of synthetic assets pegged to USD rather than crypto collateral. This brings a critical “stablecoin performance” to the decentralised finance ecosystem.
The volatility of assets like ETH makes them unsuitable for routine payments. Prices can quickly shift 10-20% day-to-day. Tether provides a stable medium of exchange for decentralized apps, akin to how fiat works in traditional finance.
Use cases include:
Without stablecoins like Tether, these transactional use cases would be severely limited.
Decentralized lending markets allow users to supply assets as collateral to take out loans of other assets.
MakerDAO pioneered this with a lending platform that uses ETH as collateral to generate DAI stablecoins. However, volatility in the collateral creates risks—falls in the ETH price can trigger the liquidation of the loan.
Tether offers a more stable form of collateral for borrowing. Borrowers can pledge USDT to take out loans in other crypto assets while avoiding liquidation risk. Lenders similarly benefit from the stability of Tether when earning interest on supplied assets.
Tether is a critical bridge between the crypto economy and traditional fiat finance. Many crypto firms hold significant USDT reserves to manage fiat liquidity needs. Traders use USDT to earn yield in DeFi while maintaining exposure to the dollar.
For most users, moving between bank accounts and crypto still relies on centralized exchanges. Tether offers an intermediate step—once fiat is converted to USDT, it can be moved and traded across the decentralized finance ecosystem.
While Tether is deeply integrated with DeFi, it has controversies. The main concerns surrounding Tether include:
Tether settled charges with the NY Attorney General in 2021 for misrepresenting its reserves. It paid an $18.5 million fine and agreed to submit reports on its reserve composition. However, many still feel the company lacks adequate transparency and auditing around its reserves.
Tether could also face actions from regulators concerned about its role in the crypto ecosystem without proper oversight. Countries like China and the UK have already taken steps to curb Tether-related activities.=
Finally, some analysts posit that unbacked USDT printing could be used to manipulate Bitcoin prices during critical moments. This remains hotly debated, though USDT supply and BTC prices have tended to move in tandem.
Despite the controversies, Tether remains essential to crypto. The calls for more transparency and auditing procedures continue, but so does Tether’s dominant position supporting DeFi’s growth.
While Tether dominates, its first-mover advantage erodes as other stablecoins gain ground. Here are some developments on the horizon:
However, even with these innovations, Tether maintains key advantages in liquidity and integration with major DeFi protocols. The network effects are substantial. Tether is also pegged to USD natively, avoiding potential divergences faced by algorithmic models.
It is unlikely anything will ultimately unseat Tether in the near to mid-term. Crypto regulations may pose the largest threat if restrictions are imposed on Tether’s business.
Barring that, Tether remains the lifeblood of DeFi by providing a critical utility that decentralized alternatives cannot yet match.

Tether has played an indispensable role in the growth of decentralized finance over the past few years. Its ability to provide liquidity, collateral, transaction capacity, and fiat bridging underpins various DeFi applications.
However, concerns persist around transparency, auditing, and regulatory risk. While competitors are emerging, Tether enjoys enormous network effects in DeFi protocols that rely extensively on USDT stablecoins under the hood.
Ultimately, Tether represents both the incredible potential and lingering risks of the DeFi ecosystem. Its future remains uncertain, but its integral utility for the present is unquestioned.
