Best DeFi Projects for Crypto APIs

Ethereum is the community-run technology that powers the cryptocurrency, Ethereum (ETH), and thousands of decentralized apps. Ethereum is a technology that allows for digital money, global payments, as well as applications. The community has created a vibrant digital economy, new ways for creators of online income, and many other benefits. It's accessible to anyone, anywhere in the world. All you need is the internet. Today, billions cannot open bank accounts and others have their payments blocked. The Ethereum decentralized finance system (DeFi), never sleeps nor discriminates. You can send, receive and borrow money anywhere in the world with an internet connection. We can now access 'free' internet services without having to give up our personal data. Ethereum services are available by default. You only need a wallet. These services are free and easy-to-set up. They can be controlled by you and work without your personal information. Stake your ETH to become an Ethereum validator. Staking is a public good for the Ethereum ecosystem. You can help secure the network and earn rewards in the process.

Compound is an algorithmic autonomous interest rate protocol designed for developers. It unlocks a wide range of financial applications. You and your users will enjoy higher returns. Your application can automatically earn the current market rate for balances. You can earn interest by putting money into your product. Earn by the block. Expand functionality without sacrificing liquidity Tokenize balances. You can withdraw assets at any time or transfer balances into cold storage, to other users, etc. While assets are in cold storage, earn interest. No trading fees, no slippage, no problem. Tap into the Compound Protocol to gain access to a global liquidity pool for each asset. The Compound Protocol lends assets without a time limit; balances can be repaid at any time, and interest accumulates per block on the Ethereum network.

Aave is an open-source, non-custodial liquidity protocol that earns interest on deposits and borrowings. Aave is a non-custodial, decentralized money market protocol that allows users to participate as either depositors or borrowers. To earn passive income, depositors provide liquidity to market participants to generate passive income. Borrowers can borrow in either an overcollateralized or undercollateralized fashion (perpetually) to obtain a loan. Aave is committed to security and we constantly improve our protocol. The funds are kept in a non-custodial smartcontract on the Ethereum blockchain. Your wallet is yours to control. Code auditable and regulated. Aave Protocol has conducted audits using trail of bits, open Zeppelin, consensys diligence and certora to ensure top-notch security. All audits are available publicly.

Synthetix, a decentralised protocol for issuing synthetic assets, is built on Ethereum. These synthetic assets are secured by the Synthetix Token (SNX), which, when locked in the contract, enables the issuance synthetic assets (Synths). This pooled collateral model allows users to convert Synths directly using the smart contract without the need for counterparties. This mechanism solves liquidity and slippage problems experienced by DEX's. Synthetix currently supports synthetic fiat currencies as well as cryptocurrencies (long- and short-term) and commodities. SNX holders are encouraged to stake their tokens because they receive a pro-rata share of the fees generated by activity on Synthetix.Exchange. This is based on their contribution towards the network. It is the right of participation in the network and the ability to capture fees from Synth exchanges. From this, the value of the SNX token can be derived. The trader does not need to have SNX to trade on Synthetix.Exchange.

Uniswap, a fully decentralized protocol that automates liquidity provision on Ethereum, is a fully decentralized protocol. Unstoppable liquidity for thousands and hundreds of applications. Uniswap allows developers, liquidity providers, and traders to join a financial market that is open and accessible for all. We are committed to open-source software and the development of the decentralized internet.

Connect your smart contract with the outside world. Chainlink's decentralized Oracle network provides reliable, tamperproof inputs and outgoings for complex smart contract on any blockchain. Start building your universally connected smart contracts. To connect high-quality and accessible data/APIs to any smart contracts, use decentralization, trusted data, premium data, cryptographic proofs, and trust nodes. A flexible framework can be used to retrieve data from any API, connect to existing systems, and integrate any blockchain, both now and in the future. Integrate battle-tested and proven oracle solutions that have secured billions in value for leading blockchain projects. Independently verify Chainlink's open source code, performance of its oracle network, and quality of individual node operator.
