Intro to Shell
The first DeFi super dapp. Swap and LP anything across major DeFi protocols from one intuitive interface.
What is Shell Protocol?
Shell Protocol is the first DeFi super dapp. Access as many DeFi protocols as you want, without connecting to a hundred different dapps. Instead, use just one dapp for every protocol (like Beefy, Aave, Uniswap, Curve, Balancer, Pendle, and Aerodrome). Wrong chain? Zap into any protocol from other chains in one click. Best of all, Shell is open source and permissionless—any developer can connect their protocol or build their dapp on the platform.

Imagine a DeFi super dapp...
In five years, no one will build dapps for their protocols. Instead, they'll just plug into platforms like Shell and instantly connect to users.
Shell minimizes the first mover advantage, ensuring new protocols can immediately access a strong user base, while users gain the latest tools without navigating a tangled web of browser tabs. It's DeFi, unified.
Swap and LP anything across major DeFi protocols from one intuitive interface. Trade tokens and NFTs, stake, optimize your holdings, and track market data in the DeFi super dapp.
Why Shell Protocol?
Reduce development and marketing costs by plugging your dapp into Shell and instantly connecting with other major DeFi protocols.
Shell Protocol lets you atomically combine any set of transactions, like LPing, lending/borrowing, or making multi-token and NFT swaps—all while significantly reducing gas fees.
Shell is the home for clean, modular DeFi contracts: Its design reduces code complexity for builders and improves user experience.
Architecture Overview
Shell Protocol is a set of EVM-based smart contracts. Unlike other DeFi protocols that rely on monolithic, single-purpose smart contracts, Shell is a hub for a modular ecosystem of services. Its design makes it much simpler to bundle several smart contracts or build new ones, and for users to batch many services in one transaction.
Shell's main smart contract is the Ocean, a shared accounting system for easily composing DeFi primitives.
Love AMMs?
Proteus can precisely replicate any shape bonding curve with dramatically increased precision. Well-designed curves capture significantly more trade volume than the competition.
History of Shell v1 (Retired)
In October of 2020, Shell Protocol launched its first-ever AMM pools on Ethereum mainnet, known as Shell v1. They were a novel approach to a particular set of problems, offering deep liquidity and (presciently) broken peg protection for like-value tokens (such as stablecoin-stablecoin or wrapped BTC-wrapped BTC). Unfortunately Shell v1 was unique in offering broken peg protection, otherwise more protocols may have been able to mitigate damage caused by the great stablecoin crash of 2021.
A visionary product in many ways, Shell v1 also contained the seeds of an ambition for a composable liquidity network — an ambition now borne out by its v2 and v3 successors. As such, after nearly two years of active life, Shell v1 transitioned into a graceful retirement.
