STELLAR TECHNOLOGY ECOSYSTEM

Explore the Stellar Technology Stack

Stellar is an open-source Layer 1 blockchain designed for digital assets, payments and applications that connect blockchain infrastructure with existing financial rails. Its ecosystem includes native asset functionality, Soroban smart contracts, RPC infrastructure, SDKs and Anchor Platform standards for financial integrations.

More Than a Payment Network

Build Applications Around Stellar's Financial Infrastructure

Stellar provides native blockchain capabilities for issuing assets, transferring value and building applications around accounts, transactions and financial assets. Developers can build applications directly on the network or add Soroban smart contracts when programmable onchain logic is required.

A major part of the Stellar ecosystem is its approach to connecting blockchain applications with traditional financial infrastructure. Anchors and Stellar Ecosystem Proposals provide standardized ways for wallets, exchanges, asset issuers and financial service providers to interact with deposits, withdrawals and cross-border payment workflows.

Web30 India works across this technology stack to build payment applications, digital asset platforms, wallets, financial infrastructure, tokenized asset solutions and Soroban-based applications.

Application & Integration Layer

Stellar Core

Stellar Core is the network software responsible for participating in Stellar's consensus and ledger operations.

Accounts & Assets

Accounts hold balances and participate in transactions. Stellar assets are identified through an asset code and issuer, with control and configuration associated with the issuing account.

Transactions & Operations

Stellar transactions contain operations that define actions such as payments and other changes to the ledger.

Soroban Smart Contracts

Soroban provides programmable smart contracts integrated into the Stellar network. Contracts are written in Rust and compiled to WebAssembly for deployment.

Stellar RPC

RPC provides an interface for applications to interact with the network and with Soroban smart contracts.

Application & Integration Layer

Wallets, payment applications, exchanges, financial platforms and business systems connect to Stellar through SDKs, RPC services, Anchor infrastructure and other ecosystem components.

Soroban Development Stack

Add Programmable Logic to Stellar

Soroban is Stellar's smart contract platform. It is integrated into the Stellar blockchain rather than operating as a separate blockchain. The current primary development environment uses Rust and the Soroban SDK.

From Payment Request to Settlement

User & Payment Initiation

A customer, business or application initiates a payment through a wallet or financial application.

Asset & Recipient Validation

The application validates the selected asset, destination account, payment amount and required business rules.

Authorization & Signing

The transaction is constructed and authorized through the appropriate wallet or signing infrastructure.

Stellar Network Submission

The signed transaction is submitted to the Stellar network through the application's selected network infrastructure.

Ledger Processing

Stellar processes the transaction and records the resulting asset movement on the ledger.

Settlement & Application Update

The application receives the transaction result and updates balances, payment status, records and downstream financial workflows.

For applications using anchors, additional KYC, fiat conversion, deposit or withdrawal steps can be incorporated around the blockchain transaction.

Stellar FAQs

Everything you need to know about our enterprise blockchain engineering process, costs, security, and architectures.

Stellar is an open-source, decentralized peer-to-peer blockchain network designed for applications involving digital assets, payments and connections with existing financial infrastructure.
Soroban is Stellar's smart contract platform integrated into the Stellar blockchain. It allows developers to deploy programmable contracts alongside Stellar's existing asset and payment capabilities.
Rust is the primary language currently supported for Soroban smart contract development, with contracts compiled to WebAssembly.
Yes. Applications can use Stellar's native accounts, assets and payment capabilities without deploying Soroban smart contracts. Stellar's developer documentation explicitly supports application development both with and without smart contracts.
Stellar assets are associated with an issuing account and an asset code. The issuer controls important asset settings through the account that issues the asset.
Anchors are services that connect Stellar-based assets and applications with traditional financial systems. They can support functions such as deposits, withdrawals, KYC workflows and cross-border payment services.
SEP-24 is a Stellar ecosystem standard for hosted deposits and withdrawals. It allows wallets and other applications to interact with an anchor through a hosted user experience that can include KYC collection.
SEP-31 is a Stellar ecosystem standard for cross-border payments. It defines an API-based interaction model for services participating in Stellar-based cross-border payment flows
Horizon remains an existing Stellar API, but current Stellar documentation states that it is nearing end-of-life and will eventually be deprecated in favor of Stellar RPC and newer data services. New architecture should therefore evaluate the current Stellar data stack rather than assuming Horizon is the long-term integration layer.
Yes. Stellar supports native asset issuance and smart contract capabilities through Soroban, making it possible to build tokenized asset infrastructure with issuance, ownership, transfer and programmable workflows
