standards

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
