About Bancor
Bancor is a pioneering protocol in decentralized finance (DeFi), credited with launching the first Automated Market Maker (AMM) back in 2017. It remains at the cutting edge of DeFi innovation with products like Carbon DeFi, Arb Fast Lane, and a suite of liquidity and trading tools that redefine on-chain market participation. Bancor empowers users with advanced features like MEV protection, zero maker fees, and permissionless strategy execution.
Designed to offer an intuitive yet powerful DEX infrastructure, Bancor combines innovation with decentralization. From concentrated and asymmetric liquidity to automated arbitrage and strategy backtesting, Bancor provides a versatile platform for developers, traders, and liquidity providers across multiple EVM chains.
Bancor has consistently led the DeFi sector in product innovation. The journey began in 2017 with the introduction of the first constant product AMM, establishing a blueprint for liquidity pools that became foundational across the ecosystem. The launch of Smart Tokens — precursors to LP tokens — further advanced how liquidity and tokenomics could be automated.
In 2020, Bancor introduced Amplified Liquidity (also known as Concentrated Liquidity), enabling users to focus liquidity within tighter price ranges to reduce slippage and increase capital efficiency. By 2022, the protocol had evolved into Carbon DeFi, a groundbreaking platform featuring asymmetric liquidity curves that allow independent buy and sell pricing strategies — a first in on-chain trading.
2023 marked the release of Arb Fast Lane, a sophisticated arbitrage automation layer that maximizes efficiency across Bancor’s own products and other DEXs in the market. This innovation identifies and executes profitable arbitrage trades between Bancor AMM, Carbon DeFi, and external liquidity venues without the need for oracles or external keepers.
Now active across over 10 blockchains and powering more than 5 decentralized exchanges, Bancor’s stack includes features such as zero fees for makers, fully on-chain range and limit orders, execution bots, MEV resistance, and auto-compounding strategies. These technologies benefit traders, market makers, token projects, DEX builders, and liquidators alike.
Compared to other DeFi platforms like Uniswap, Curve, and Balancer, Bancor stands out with its unique commitment to on-chain programmability and user-controlled trading logic. Its simulator and execution infrastructure are unmatched for those looking to test and automate real trading strategies on live networks.
Bancor provides numerous benefits and features that make it a standout project in the decentralized exchange (DEX) landscape:
- Asymmetric Liquidity Strategies: Users can define custom buy and sell curves separately, allowing advanced trading logic not possible on traditional AMMs.
 - Zero Trading and Gas Fees for Makers: Carbon DeFi charges no trading fees for strategy makers when orders are filled, making it highly capital-efficient.
 - MEV Protection: The protocol is designed to resist sandwich attacks, providing more secure execution for liquidity providers and traders.
 - Cross-Chain Support: Active across 10+ blockchains, Bancor enables a broad ecosystem of DeFi interaction for developers and liquidity users.
 - Carbon Simulator: Users can backtest trading strategies using real historical data, offering a unique approach to DeFi strategy development.
 - Execution Bots: Advanced infrastructure automates the strategy execution lifecycle without needing oracles, keepers, or hooks.

Bancor FAQ
Carbon DeFi lets users create separate curves for buying and selling, allowing distinct price ranges, fees, and behaviors for each side. This gives traders full control over execution logic and simulates orderbook-like mechanics on-chain via Bancor.
Arb Fast Lane is integrated into the Bancor protocol and operates autonomously to identify and execute profitable arbitrage opportunities across multiple DEXs and blockchains, requiring no user setup or intervention. It supports seamless liquidity balance across Bancor's own AMMs and the broader market.
Bancor’s architecture avoids reliance on mempool vulnerability and doesn't expose pending trades to front-runners. Because trades execute only when strategy parameters are met, and without external hooks, they are naturally protected from MEV sandwich attacks via Bancor.
Yes, Bancor’s Carbon DeFi strategies run fully on-chain with no dependence on price oracles, keepers, or external bots. This reduces trust assumptions and allows fully autonomous execution based on predefined conditions set by the user on Bancor.
The Carbon Simulator lets you backtest trading strategies using historical price data across supported blockchains. It helps fine-tune buy/sell ranges, spread, and fees before capital deployment, giving users a safe and data-driven entry point into on-chain strategy trading.
