📄 Stellar Consensus Protocol

A brief overview of how the Stellar Consensus Protocol (SCP), a proof of agreement protocol, enables consensus and validates transactions on the network.

📄 Stellar Decentralized Exchange

Learn how conversion liquidity enables direct trading. Understand how markets work, provide liquidity, and enable decentralized asset swaps on the network.

🗃️ Stellar Data Structures

Learn how accounts, assets, contracts, events, and ledgers fit together to describe everything living on the Stellar network.

🗃️ Operations & Transactions

Trace how Stellar transactions bundle operations, flow through the network, and unlock asset transfers or contract calls.

📄 Fees, Resource Limits, and Metering

Learn how fees, resource limits, and metering work on the Stellar network. Understand cost structures, transaction pricing, and smart contract resource limits.

📄 Stellar Ecosystem Proposals

Learn about Stellar Ecosystem Proposals (SEPs), standards that enhance interoperability, improve functionality, and expand the network's capabilities.

🗃️ Smart Contracts

Dive into Soroban smart-contract concepts, lifecycle guidance, and authorization patterns so you can ship production-ready code on Stellar.

🗃️ Data Format

Understand Stellar's XDR and JSON encodings so you can inspect transactions, debug payloads, and interchange data with other systems.

📄 Anchors

Learn about the on and off ramps on Stellar called anchors and their role in bridging between the traditional financial system and blockchain networks.
