# base

Base is built as an Ethereum L2 on the OP stack, with the security, stability, and scalability you need to power your dapps. Confidently deploy any EVM codebase and onramp your users and assets from Ethereum L1, Coinbase, and other interoperable chains.



Coinbase is the most trusted cryptocurrency platform, and an ideal starting point if you're new to crypto. They started in 2012 with the idea that anyone, anywhere, should be able to easily and securely send and receive Bitcoin. Today, they offer a trusted and easy-to-use platform for accessing the broader cryptoeconomy. [When you deposit on a centralised exchange you receive an IOU for your tokens, which shows up as your wallet balance. When your tokens are held on a centralised exchange, you don't physically own them – the exchange does, and you may lose them]


Celer Network

Celer is a blockchain interoperability protocol enabling a one-click user experience accessing tokens, DeFi, GameFi, NFTs, governance, and more across multiple chains. Developers can build inter-chain-native dApps using the Celer Inter-chain Message SDK to gain access to efficient liquidity utilization, coherent application logic, and shared states. Users of Celer-enabled dApps will enjoy the benefits of a diverse multi-blockchain ecosystem with the simplicity of a single-transaction UX, all from a single chain.

friend tech

Buy and trade tokens of your twitter "friends" onchain. - Owning a "key" (previously referred to as a "share") to a twitter friend allows you to talk to them and read their "alpha" in a private chat with other keyholders. - Speculators may wish to buy keys in the hope the value will go up as more people buy keys of twitter friends. ### Risk - On signing up you must give friend tech permissions to tweet on your behalf (you can revoke this in Twitter settings after you've signed up). - There is currently no Privacy Policy (23-Aug-2023). - The value of friends' keys can go up or down depending on demand, so if you buy a key there is a chance it will go down in value. - There have been similarities drawn with friend tech being similar to "paid groups". ### Reward - By paying for keys you get to talk with people you may not otherwise have the opportunity to talk to. - Speculators have bought popular people's keys early, before their value goes up, allowing them to sell keys for a profit as demand (and price) increases. - When people trade your keys you earn a fee from those trades (as does friend tech).

Odos is a decentralized exchange aggregator that optimizes order routing across multiple blockchain protocols, accessing over 700 liquidity sources and thousands of token pairs. It uses a proprietary algorithm for Smart Order Routing (SOR) to find the most efficient paths for swaps, ensuring users get the best rates while maintaining self-custody and security. Odos stands out by allowing atomic multi-token swaps in a single transaction, aiming to save on gas costs and reduce market impact for its users.


Uniswap is a decentralized exchange protocol (DEX). It allows people to set up or contribute to liquidity pools consisting of various ERC-20 token pairs, or to use the available liquidity to swap their tokens against another using its Automated Market Maker (AMM) mechanism. ### Why AMMS are one of the building blocks in the crypto space as they always provide users with a price between two assets. Uniswap uses a simple X * Y = K, formula to price assets where x is the amount of one token in the liquidity pool, and y is the amount of the other. k is a fixed constant, meaning the pool’s total liquidity is always the same. ### Risk There are various risks involved with using AMMS. These include but are not limited to: Protocol Risk - risk due to mechanics in the design of a protocol. Even when the protocol functions as intended there might be risks e.g. high slippage incurred in trades due to the liquidity curve set-up Smart contract risk - This is risk from an error in the code causing the contract to operate in ways unexpected by the developers. It might leave the code vulnerable to exploits or other attacks Cybersecurity risk - Hackers, Exploiters or other malicious actors trying to attack Uniswap ### Reward Uniswap is arguably one of the largest AMMs in crypto and is usually the protocol where tokens find the most liquidity. Its UI/UX is extremely simple and users can trade most tokens with little problems.
