A Primer on Bancor’s New Buying and selling Protocol, Carbon | by Carbon

Carbon is a brand new groundbreaking strategy to on-chain buying and selling and liquidity. It was created by the inventors of the AMM (Bancor), who’ve been constructing in DeFi since 2017. Carbon is at present in Beta, with a whole bunch of automated buying and selling methods already dwell.

Within the phrases of one crypto researcher — “the upside potential right here is the most important I’ve seen from a brand new DEX.”

From a consumer’s perspective, what makes Carbon distinctive is it brings automated buying and selling methods which can be fashionable in CEXs — however have till now been unavailable or prohibitively expensive in DeFi — to a totally on-chain, permissionless protocol. These methods embrace:

  1. Onchain Restrict and Vary Orders: Execute one-time, irreversible trades at particular costs (restrict order) or inside a selected vary of costs (vary order).
  2. Grid Buying and selling (“purchase low, promote excessive”): Purchase in a single value vary and promote in the next value vary. Use a single liquidity place and keep away from having to handle a number of orders. For instance, an ETH technique that buys ETH between $1800–1900 and sells ETH between $2100–2200.
  3. Momentum Buying and selling: Purchase right into a rising asset and progressively promote because the token continues to rise.
  4. Arb Pegged Property: Set a method on two belongings which can be pegged/correlated in worth (e.g., rETH/ETH, wstETH/ETH, ETH2x-FLI/ETH) and use value ranges that purchase and promote the belongings once they diverge (“de-peg”) and once they re-peg.


What makes most of these methods doable — and what distinguishes Carbon from present AMMs and DEXs — are the next options:

  • Customized Unfold: Whereas present AMMs power their liquidity suppliers to undertake the payment of the AMM they’re offering liquidity to, Carbon lets LPs set their very own customized payment (or unfold) by choosing the precise costs the place they’d like to purchase and promote their tokens.
  • Rotating Liquidity: Liquidity is routinely moved between the technique’s chosen purchase and promote ranges as orders are executed. Ranges and budgets assigned to every order are absolutely customizable by customers, by way of front-end UI or SDK.
  • Irreversible Orders: Person liquidity trades in a single course, irreversibly, eliminating the necessity to monitor your order and withdraw liquidity on the proper time.
  • MEV Resistance: Spot buying and selling is protected against MEV sandwich assaults (extra data).
  • Zero Gasoline/Buying and selling Charges: Technique creators pay zero gasoline charges and nil buying and selling charges on trades executed by their technique, solely a small gasoline payment to open/shut their technique.
  • On-Chain Adjustability: As soon as a method is in place, it may be adjusted with no need to take away and recreate the place, enabling hyper gas-efficient updates.

From X*Y=Ok to Asymmetry: A Temporary Historical past of On-Chain Liquidity

Carbon marks a brand new period for on-chain buying and selling and liquidity.

The primary era of on-chain liquidity — supported by constant-product AMMs — required liquidity suppliers to purchase and promote tokens throughout an infinite variety of costs.

The introduction of concentrated liquidity gave liquidity suppliers the power to set a selected vary of costs the place they provide to purchase and promote tokens.

Carbon is the primary protocol to supply “uneven liquidity”, a brand new type of concentrated liquidity the place market makers can distinguish between their purchase and promote ranges. Purchase/promote ranges may be positioned at any value primarily based on the place a consumer expects a given token will commerce — and liquidity routinely rotates to fill trades in solely the ranges outlined by the consumer. These capabilities give on-chain merchants, fund managers and DAOs unprecedented management to execute extra exact and expressive buying and selling methods in a totally on-chain, permissionless method.
