Stellar Service Integration

[3m1n3nc3]

Description

Create service layer for Stellar blockchain interactions.

File Location

src/services/stellar.service.ts

Design Reference

Service that handles all Stellar operations (wallet, payments, credentials).

Tasks

• Configure Stellar SDK with network settings
• Create wallet generation function
• Implement balance checking for accounts
• Add payment/sending functions
• Create credential issuance on Soroban
• Implement credential verification
• Add error handling for blockchain failures
• Write unit tests with mocks

Acceptance Criteria

• Service initializes with correct network (testnet for development)
• Wallet generation returns valid Stellar keys
• Balance checks return correct amounts
• Payment functions create proper transactions
• Credential functions interact with Soroban contracts
• Errors are caught and wrapped appropriately

Hello,

I am a smart contract and full-stack developer interested in contributing to this issue. I’m an experienced contributor on OnlyDust and participated in Drips Wave 1 and wave2, with hands-on experience in Rust, Soroban, Cairo, Solidity, and TypeScript.

I’m passionate about building secure and scalable blockchain solutions, with a strong focus on writing clean, maintainable code. Based on the scope of this issue, I’m confident I can deliver a complete solution within 22 hours of assignment.

I would appreciate the opportunity to contribute and help move this forward.

I’m interested in tackling this! I have a strong background in smart contract development and full-stack systems, so I'm well-equipped to handle the requirements here. Could you please assign this to me?

Hi maintainers, I'm Promise Adedokun. I'm a full-stack developer with 4+ years of experience in Stellar blockchain integration and building robust service layers for Soroban interactions. I'd like to work on this Stellar service integration. I can configure the Stellar SDK with proper network settings, implement wallet generation, balance checking, payment functions, Soroban credential issuance and verification, and add comprehensive error handling with unit tests using mocks. My ETA is 6-8 hours.

Hello maintainers
I’m interested in working on this issue. I specialize in building scalable backends and secure blockchain systems, which seems to be the core of what’s needed here. I’d love to apply my experience in smart contract auditing and full-stack development to ensure this is handled efficiently.

Hi team, I’d love to tackle this issue. I’m a Full Stack Engineer highly experienced with Node.js, strict TypeScript, and integrating the Stellar SDK and Soroban smart contracts into robust backend services.

Action Plan:

Network & Wallets: Configure the Stellar SDK to dynamically initialize on the correct network (e.g., testnet) and implement secure, native wallet keypair generation alongside accurate balance checking.

Transactions & Soroban: Build resilient payment functions to construct and submit proper transaction envelopes. I will integrate direct Soroban contract calls for seamlessly issuing and verifying credentials on-chain.

Resilience & Testing: Implement a strict error-handling layer to catch and appropriately wrap blockchain-specific failures. I will write comprehensive unit tests using robust network mocks to guarantee reliability without relying on live network calls.

I am ready to start immediately and will submit a clean, production-ready PR!

Hi Maintainer! If this issue is assigned to me, I will implement a Stellar service layer that encapsulates blockchain interactions including wallet generation, balance queries, payments, and Soroban credential operations using the Stellar SDK. The service will include robust error handling and unit tests with mocks to ensure reliable integration with the Stellar testnet during development.
