Stellar SDKs & Developer Tools

SoroBuild

Revolutionizing Dapp creation on Soroban with a user-friendly Bubbl.io no-code plugin.

SecuRx

SecuRx makes medical prescriptions safer, easier and more reliable than any previous solution for all healthcare systems worldwide.

NebulaVRF

NebulaVRF is the first fully on-chain Verifiable Random Function for Soroban, providing provably fair randomness for games, lotteries and NFT minting on Stellar. A core GameFi primitive: on-chain games and play-to-earn mechanics use it for tamper-proof loot, matchmaking and draws on Stellar.

Stellot

Privacy-first voting platform powered by the Stellar blockchain, providing transparent, verifiable, and anonymous online voting solutions.

Astrocore

Astrocore is an alternative implementation of stellar-core, the core component of the Stellar network.

Soroban Hub

Manage, monitor and interact with your deployed contracts from a single and free to use desktop app.

Expand Network

Expand.network offers a unified API that connects developers to over 100 decentralized finance (DeFi) endpoints across more than 40 blockchains and protocols, including both EVM and non-EVM platforms.

Relax

Track human resource assets (vacation days, salary, etc) on Stellar.

Stellar Confidential Token SDK

Confidential-token SDK build from the Stellar Builder Summit SP 26 (2nd place) by aguilar1x.

Cards402

SDK, CLI, and MCP server for issuing virtual Visa cards to AI agents after payment in USDC or XLM. Winner at the Stellar Hacks: Agents hackathon (x402/MPP).

x402 MCP Stellar Template

Node.js, Python, and Go templates for building paid MCP servers with x402 on Stellar — wallet provisioning, spending limits, mainnet-proven. Winner at the Stellar Hacks: Agents hackathon.

TollPay

Middleware and SDKs for monetizing MCP tools with per-call USDC payments on Stellar mainnet. Winner at the Stellar Hacks: Agents hackathon (x402/MPP).

Stellar MPP SDK

Official SDK implementing the Stellar payment method for MPP (Machine Payments Protocol) charge payments and off-chain payment channels with on-chain settlement. The reference building block for agent payment flows on Stellar.

Para

Para is an embedded wallet infrastructure platform that lets fintech developers integrate secure, MPC-powered wallets directly into their apps — enabling remittances, stablecoin payouts, and cross-border payment products on Stellar with no seed phrases or separate downloads required.

Colibri

TypeScript-first toolkit for building Stellar and Soroban applications — deterministic error handling, composable workflows, and an extensible plugin architecture. Published on JSR as @colibri, with a companion examples repo. By fazzatti (Fabricius Zatti / Fifo).

Soropass

A minimal passkey SDK and drop-in create / sign / recover components for Stellar smart accounts, built to plug into stellar-wallets-kit. ES256-only, always low-S, proven on testnet.

LumenWipe

LumenWipe closes a Stellar account and recovers its locked XLM reserves. It handles every step automatically: signer normalization, data entry removal, DEX offer cancellation, LP withdrawal, DeFi position exits (Blend, Aquarius, Soroswap, Phoenix, FxDAO), asset conversion, trustline removal, and the final account merge. The project responds to the Account Demolisher RFP. It extends the public-domain stellar.expert/demolisher/public by Orbit Lens with the piece that tool lacks: full Soroban and DeFi parity. Any account with a Blend loan, an Aquarius LP position, or a Soroswap pair share cannot be closed with any existing tool today. All transactions are built and signed in the browser. The backend is read-only and stateless, never in the signing path. A transparent mediator account handles CEX destinations, since no major exchange supports ACCOUNT_MERGE. A read-only allowance inspector lets users revoke token approvals without closing their account. The classic wind-down runs on testnet and mainnet today.

Authline

Trustline onboarding protocol and SDK for Stellar. Bundles trustline creation and authorization into a single on-chain transaction (CAP-73 + Soroban), enabling wallets and exchanges to onboard users to any Stellar asset — including regulated AUTH_REQUIRED tokens — with one wallet signature. Ships a TypeScript SDK (@theaha/authline), Soroban router + authorizer contracts, a self-hostable relayer, and a multi-asset activation dApp at authline.io.

SODAX

A cross-network execution and liquidity system spanning 20 networks, including native Bitcoin and tokenized equities (xStocks). Wallets, DEXs, and lending protocols integrate SODAX to ship cross-network features faster and extend their reach to every network SODAX touches. SODAX is infrastructure for modern money.

Stellar Flutter SDK

Soneso's open-source Stellar SDK for Flutter/Dart — build and sign transactions, query Horizon, and interact with Soroban smart contracts via RPC, with support for 18 SEPs.

Stellar Wallets Kit

Stellar Wallets Kit (by Creit Tech) is a single TypeScript library that handles integration with all major Stellar ecosystem wallets at once — xBull, Freighter, Albedo, Rabet, Ledger, Trezor, WalletConnect, HOT Wallet and more behind one interface, so dApps integrate every wallet without shipping per-wallet code. An INTEGRATION KIT for developers, not an end-user wallet product.

RouteDock

RouteDock is a unified payment execution layer for autonomous agents on Stellar: one SDK (@routedock/routedock on npm) whose single client.pay() call routes across the three Stellar agent-payment protocols — x402 (Coinbase), MPP charge, and MPP session channels — selecting the mode from the provider's routedock.json manifest. Supports Stellar testnet and mainnet.

Smart Account Kit

TypeScript SDK for deploying and managing OpenZeppelin smart account contracts on Stellar with WebAuthn passkey authentication — passkey/Ed25519/delegated signers, context rules, typed policy clients, fee sponsoring. A client for the OpenZeppelin stellar-contracts smart-account contract, by kalepail (Tyler van der Hoeven). Smart-account TOOLING for developers, not an end-user wallet.
