Community skills

Skills built and maintained by members of the Stellar community. Each project has its own install instructions; follow the link on a card to set it up with your agent.

Community skills are independently developed and are not reviewed, endorsed, or maintained by the Stellar Development Foundation. Inclusion in this directory does not imply any warranty, security audit, or recommendation by SDF. You are solely responsible for evaluating any community skill before use, including reviewing its code, license, and security practices.

Agent Browser WebAuthn

Drive passkey and Stellar smart account browser tests with agent-browser and Chrome DevTools virtual WebAuthn authenticators.

Integrate with or build Stellar anchors (fiat on/off-ramps, deposits/withdrawals, KYC). Covers core SEP flows (1/6/10/12/24/31/38) and common integration pitfalls.

Blux

Bring Web2 users to Stellar with passkey, OAuth, email, or wallet login. Customize the UI, then use wagmi-style React hooks and JavaScript functions to read balances, call Soroban contracts, and send transactions.

Caatinga

Deploy and manage Soroban contract lifecycles with the Caatinga CLI (ctg). Covers the init → doctor → build → deploy → generate → invoke workflow, the multi-contract Deployment Graph, versioned caatinga.artifacts.json as the source of truth for contract IDs, generated TypeScript bindings, and wallet adapters (Freighter, Stellar Wallets Kit) — with hard rules against raw secret keys on the command line and hand-edited artifacts or bindings.

Cogladius

Contextio SDK

Integrate contextio-sdk: verifiable, non-custodial legal context binding (Legal Context Protocol / LCP) for Stellar treasury and payroll. Covers Sign In With Stellar (SEP-53) wallet auth, reading a tenant's treasury/payroll/agent state, triggering an agent proposal, and independently hashing/verifying an LCP document against an on-chain hash.

Crypto Implementation Evaluation Writing

Draft, revise, or review implementation and evaluation sections from code and experimental results. Covers supported performance claims, fair comparisons, setup and amortization, and missing evidence.

Crypto Prior-Work Comparison

Draft or review prior-work comparisons and comparison tables in cryptography papers. Aligns models, construction variants, costs, and evidence so each claimed improvement states its conditions and its cost.

Crypto Proof Auditor

Audit or complete cryptographic proofs, reductions, simulators, and security theorems. Checks that the conclusion follows from the stated definition, model, and assumptions, and flags gaps instead of hiding them with new assumptions.

Cryptographic Correlation Accounting

Define and compare correlation counts, PCG expansion ratios, and throughput units by algebraic relation, domain, grouping, and denominator. Use when lanes, entries, blocks, or correlation rates are ambiguous.

Cryptographic Protocol Implementation

Implement, optimize, reproduce, or review cryptographic protocol code against its specification. Covers circuit, transcript, state, sampler, and adapter fidelity, plus the security obligations that code changes affect, with MPC and ZK optimization guides.

Cryptography AI Acknowledgements

Draft or review AI-use disclosures in cryptography papers from the actual record of assistance and human checking. Separates research, writing, code, experiments, and formalization, and does not certify proofs or infer AI use.

Cryptography Benchmarking

Design, run, or audit cryptographic experiments with explicit timing, communication, memory, and statistical accounting. Defines the measured object, operations, units, and hardware before results go into tables.

Cryptography Literature Evidence

Find and verify primary-source cryptography claims with exact source locators. Covers citation checks, comparison of paper versions, and literature surveys that rely on the paper itself, not search snippets or summaries.

Cryptography Manuscript QA

Check cryptography manuscript sources, LaTeX builds, PDF page locations, references, layout, and paper-to-code consistency. Resolves the active include graph and requested version before citing pages or editing.

Cryptography Research Artifacts

Prepare, document, anonymize, validate, and package cryptography research artifacts for reviewers. Builds claim-to-command maps and validates the release from a fresh extraction.

Cryptography Research Framing

Turn a rough cryptography idea into a precise research question. Separates facts, assumptions, and conjectures, and proposes definitions, candidate lemmas, constructions, counterexamples, or obstructions as the next mathematical step.

Cryptography Writing

Draft or minimally edit cryptography manuscripts: definitions, theorem statements, security arguments, abstracts, and technical overviews. Presents simulation proofs as a simulator plus named hybrids and keeps the construction and guarantee unchanged.

DeFindex SDK

Integrate DeFindex vaults on Stellar with the @defindex/sdk TypeScript package. Covers vault deposits and withdrawals, balance and APY queries, programmatic vault creation, and the unsigned-XDR signing pattern for backend and bot integrations.

Eunomia Bounded Agent Treasury

Give an AI agent a non-custodial, contract-bounded spending account on Stellar with Eunomia (formerly PRISM). Covers treasury deployment with per-payment and rolling daily limits, payee whitelists, time-bound agent session keys, escrow, x402-gated payments, and Groth16/BN254 ZK compliance proofs verified on-chain.

LumenLoop MCP Connect

Connect any MCP client (Claude, ChatGPT, Gemini, Cursor) to LumenLoop's free read-only Stellar ecosystem MCP and learn its query tools for directory, content, and SCF data.

MPP Discover

Find and pay APIs from 90+ services with Stellar USDC through MPP Router — including OpenAI, Anthropic, DeepSeek, Perplexity, Exa, Firecrawl, and Tavily. An agent fetches the live service catalog, picks a service, and settles per request. Every verified service is backed by a real paid call with a published Stellar transaction hash.

Nirium Agentic Payments

Charge AI agents per API call on Stellar with the Nirium toolkit: scaffold a working x402 seller with nirium-cli in one command, charge per route with x402Serve() from the nirium SDK, and read live protocol data, market state, autonomous loop status, and execution nodes through the nirium-mcp server. Live on mainnet since July 9, 2026.

OpenZeppelin Contracts

Scaffold a Stellar smart contract project with OpenZeppelin's audited Stellar contract libraries. Walks through Rust toolchain setup, Stellar CLI install, workspace dependencies, and applying the pausable and ownable macros to your contract.

PMLL

Gives AI agents persistent spatial memory so they can retain long-term context, form symbiotic memory layers, and maintain durable state across sessions; supports PPM-based context stitching, Context+ pipelines, and supermodeltools/cli for graphing and analysis. On-chain commitment anchoring on Stellar (32-byte hashes via a Soroban contract) is planned.

Pollar Wallets & Fiat Ramps

Add embedded Stellar wallets and local fiat on/off-ramps to a web or React Native app with @pollar/core and @pollar/react. Users sign in with email, social or a passkey and get a funded account with no seed phrase. Covers ramp quotes and country availability, the custodial and external signing paths, payments, sponsored (gasless) activation and trustlines, multi-venue swaps, and SEP-53 / SEP-10 ownership proofs.

ROZO Checkout

Pay for AI services with Stellar USDC — e.g. OpenRouter and Venice.ai, which cannot take Stellar directly — through a one-time deposit order and automatic invoice settlement. More AI services coming.

Position a Stellar Community Fund idea against prior submissions before applying: find similar past proposals, check what's been funded in an area, and sharpen positioning.

Scopuly Wallet

Connect Stellar dApps to Scopuly Mobile and its paired browser extension using the Provider API or Stellar Wallets Kit. Covers transaction signing, SEP-53 messages, Soroban authorization, account and network changes, and error handling.

SODAX

Build cross-network trading, lending, and asset transfers between Stellar and 20+ other networks with the @sodax/sdk TypeScript package. Covers intent quotes and status polling, Stellar trustline handling on source and destination, sponsored activation for new 0-XLM accounts, dapp-kit React hooks, and the Result error model.
