description	Stellar standards, ecosystem, and reference. Covers SEPs (Stellar Ecosystem Proposals), CAPs (Core Advancement Proposals), and a quick map for picking the right standard for wallets, anchors, payments, deposits/withdrawals, federation, deep links, and KYC. Also bundles ecosystem references (DeFi protocols, dev tools, wallets, infra, community projects) and curated documentation links. Use when you need to know which SEP applies, or want a starting point for ecosystem integrations and official docs.

Standards, Ecosystem, and Resources

Three things bundled because they're all reference material you reach for in the same moment: "which standard handles X?", "is there an existing project doing Y?", and "where's the canonical doc for Z?".

When to use this skill

• Picking the right SEP for an integration (anchors, deposits, federation, deep links, KYC, paths)
• Checking CAP status for a protocol feature you want to rely on
• Finding existing DeFi protocols, wallets, or infrastructure to integrate with rather than rebuild
• Locating official docs, SDKs, or community resources

Related skills

• Implementing a SEP-41 token interface → ../assets/SKILL.md, ../soroban/SKILL.md
• Frontend SEP-7 / SEP-10 flows → ../dapp/SKILL.md
• CAPs for cryptography (BLS, BN254, Poseidon) → ../zk-proofs/SKILL.md
• x402/MPP protocol context → ../agentic-payments/SKILL.md

Part 1: SEP / CAP Standards Reference

When to use this guide

Use this when you need:

• The right SEP/CAP for a feature or integration
• Interoperability guidance for wallets, anchors, and contracts
• A fast map from use case to official standards docs

Maintenance note

Standards status can change quickly. Before implementation, verify current status in:

• SEPs: stellar-protocol/ecosystem
• CAPs: stellar-protocol/core

Treat this file as a routing map, not a source of final governance/status truth.

High-value SEPs for app developers

Contracts and token interfaces

• SEP-0041: Soroban token interface
• SEP-0046: Contract metadata in Wasm
• SEP-0048: Contract interface specification
• SEP-0049: Upgradeable-contract guidance
• SEP-0050: NFT standard work
• SEP-0055: Contract build verification
• SEP-0056: Vault-style tokenized products
• SEP-0057: Regulated token patterns (T-REX)

Auth, identity, and metadata

• SEP-0010: Web authentication
• SEP-0023: StrKey encoding
• SEP-0001: stellar.toml

Anchor and fiat integration

• SEP-0006: Programmatic deposit/withdrawal API
• SEP-0024: Hosted interactive anchor flow
• SEP-0031: Cross-border payment flow
• SEP-0012: KYC data exchange

High-value CAPs for Soroban developers

Soroban foundations

• CAP-0046: Soroban overview
• CAP-0046 subdocuments (cap-0046-*.md): runtime, lifecycle, host functions, storage, auth, metering

Frequently used contract capabilities

• CAP-0051: secp256r1 verification (passkey-related cryptography)
• CAP-0053: TTL extension behavior
• CAP-0058: constructors (__constructor)
• CAP-0059: BLS12-381 primitives
• CAP-0067: protocol/runtime improvements including asset/event model changes

Newer and draft crypto/features

• CAP-0074: BN254 host functions proposal
• CAP-0075: Poseidon/Poseidon2 proposal
• CAP-0079: muxed-address strkey conversion proposal

Use the CAP preamble status fields as the source of truth for implementation readiness.

Quick mapping by use case

I am building a fungible token

1. Start with SEP-0041 interface expectations.
2. Prefer Stellar Assets + SAC interop unless custom logic is required.
3. If regulated, review SEP-0057 patterns.

I need upgrade-safe contracts

1. Read SEP-0049 guidance for upgrade process design.
2. Use CAP-0058 constructors for atomic initialization where protocol support exists.
3. Add migration/versioning strategy before deploying upgradeable contracts.

I am building a smart-wallet flow

1. Use SEP-0010 for web authentication flows.
2. Review CAP-0051 for passkey-related cryptographic primitives.
3. Align wallet UX and signing payloads with current SDK guidance.

I need anchor integration for fiat rails

1. SEP-0006 for API-first flows.
2. SEP-0024 for hosted interactive rails.
3. SEP-0031 when supporting payment corridors.
4. SEP-0012 for KYC data requirements.

Practical workflow for AI agents

• Step 1: Identify feature category (token, wallet auth, anchor, upgradeability).
• Step 2: Link user to the 1-3 primary SEP/CAP docs.
• Step 3: Check status/acceptance in the source repo before asserting support.
• Step 4: Implement only what is active on the target network/protocol.
• Step 5: Document dependencies on draft standards explicitly.

Part 2: Stellar Ecosystem

This guide catalogs the major projects, protocols, and tools in the Stellar ecosystem. Use this as a reference when building on Stellar to find relevant integrations, examples, and community projects.

Canonical directories — For the most up-to-date project lists, check:

• Stellar Ecosystem — Official directory (searchable by country, asset, category)
• SCF Projects — Funded projects with status tracking
