This technical blog post details the implementation requirements and mathematical foundations for integrating SPEEDEX, a novel scalable decentralized exchange design, into Stellar-core. It covers the three main protocol changes needed, the Arrow-Debreu economic model underlying SPEEDEX, and the Tâtonnement algorithm used for efficient price computation.
Stellar launched Protocol 18 on Nov. 3, integrating native automated market maker (AMM) functionality into its Layer 1 DEX. The upgrade enables permissionless liquidity pool creation with fixed 0.3% fees, positioning Stellar as the first L1 blockchain with AMM capabilities built directly into its protocol.
Stellar launched an automated market maker (AMM) at the protocol level, operating alongside its existing order book-based matching engine. The upgrade enables liquidity pools for trading fees and makes it easier to list long-tail assets with limited liquidity.
Protocol 18 upgrade vote on Nov 3rd will bring automated market maker (AMM) functionality to Stellar. SDF collaborated with ecosystem projects like Settle Network, Ultra Stellar, and Stellarport.io to ensure AMM features launch immediately upon validator approval, democratizing liquidity provision and enabling new financial services use cases.

Stellar Development Foundation shares how the ecosystem accelerated Automated Market Maker (AMM) development for Protocol 18 by involving developers early with API specs, mock environments, and Futurenet testing, enabling simultaneous product launches upon network upgrade in November.
Wilhelm Wanecek's research study estimates Stellar network electricity consumption at 0.222 Wh per transaction, with network traffic accounting for 94% of power use. The findings demonstrate Stellar's energy efficiency compared to proof-of-work blockchains and highlight the protocol's successful decoupling of decentralization from extreme power consumption.
SDF released its Q2 2021 report highlighting network growth, two protocol upgrades, $18M in Enterprise Fund investments, and the approval of Automated Market Makers for Protocol 18. The network demonstrated resilience after a temporary validator outage in April.
The Stellar Development Foundation relaunched its demo wallet with a unified interface consolidating separate protocol testing tools. The redesigned wallet now supports multiple SEPs including deposits, withdrawals, cross-border payments, and regulated assets, serving both developers and non-technical users learning Stellar protocols.
Stellar Protocol 18 proposal to add automated market makers (AMMs) was approved for implementation on June 25, 2021. AMMs will provide an alternative liquidity source alongside the existing order book exchange, enabling easier participation in market making and improving cross-asset payment efficiency.
