Roadmap

Overview

Smart Engines follows a methodical approach to multi-chain expansion, ensuring security, stability, and community alignment at every phase. This roadmap separates what is done, what is in progress and what is planned. It carries no dates.

Current Status

The testnet is live on validators operated by HSuite. It opens to developers once the security audit is complete. Mainnet has no date yet.

Live Chains

Chain	Status	Key Features
Hedera	Live	HCS topics for consensus, rule publication, governance and audit; mirror node reads
XRPL	Live	The HSUITE token, trust lines, native NFTs (subscriptions and memberships), SignerList multisig

Coming Next

Chain	Status	Expected Features
Stellar	Coming next	Accounts, issued assets, native multisig
Polkadot	Coming next	Assets pallet, native multisig
Solana	Coming next	SPL tokens, Metaplex NFTs, SPL multisig
Bitcoin	Coming next	Transfers from native multisig (P2WSH)
Ethereum, Polygon	Postponed	EVM support is postponed

Stellar, Polkadot, Solana and Bitcoin will land in Smart Engines and HSuite Wallet together.

Phase 1: Foundation (Completed)

V3 Core Infrastructure

Multi-chain core library architecture
Chain adapter abstraction layer
Threshold signing service (FROST over DKG key shares)
DKG ceremony implementation
Unified REST API
Client SDK (TypeScript) and hsuite CLI, both published on npm
Authentication system (API Key + Web3)
Token gating infrastructure
Testnet on HSuite-operated validators

Hedera Integration

Account management
HTS token operations in the adapter
HCS topic messaging: consensus, rule publication, governance and audit
Mirror node integration
Testnet deployment

XRPL Integration

Account management with trust lines
Issued currency support (the HSUITE token)
Native NFT operations (subscriptions and memberships)
SignerList multisig under validator DKG keys
Testnet deployment

Phase 2: Expansion (In Progress)

The next chains are Stellar, Polkadot, Solana and Bitcoin. Each has an adapter library; none is enabled on the testnet yet.

Polkadot Integration

Technical Milestones:

Adapter library: accounts, Assets pallet tokens, native multisig, threshold signing
Enabled on the testnet
Security audit

Solana Integration

Technical Milestones:

Adapter library: accounts, SPL tokens, Metaplex NFTs, SPL multisig, threshold signing
Enabled on the testnet
Security audit

Phase 3: Ecosystem Growth

Developer Tools

Tool	Status	Description
CLI	Available	Command-line interface for devs (`@hsuite/smart-engines-cli` on npm)
Dashboard	Planned	Web-based validator management
Playground	Planned	Interactive API testing
Templates	Planned	Starter templates for common apps

Enterprise Features

Governance Implementation

DAO service: proposals, signed votes on HCS, quorum and approval tally, execution delay, veto council
Voting mechanism: token-balance weight at a snapshot
Proposal system, including rule amendments and marketplace pricing overrides
Protocol treasury, as an autonomous fee-payer under a published rule
HSuite DUNA participation framework: membership and voting eligibility rules (HSuite DUNA governance)

Phase 4: Scale

Additional Chain Targets

Priority evaluation based on:

Community Size - Active developer ecosystem
Technical Compatibility - Architecture alignment
Economic Viability - Sustainable integration
Enterprise Demand - Customer requirements

No chain is committed beyond the ones listed as coming next.

Advanced Features

AI-powered validation rules
Additional staking utilities (subject to legal classification)
Zero-knowledge proof integration
Layer 2 support

Integration Timeline

Standard Chain Integration Process

Each new chain goes through the same stages, in order:

Risk Management

Technical Risks

Risk	Mitigation
Chain protocol changes	Modular adapter architecture
Performance bottlenecks	Separate tiers, caching
Security vulnerabilities	Security audit before the testnet opens to developers

Operational Risks

Risk	Mitigation
Key personnel	Knowledge documentation, team expansion
Regulatory changes	Legal counsel, compliance monitoring
Market conditions	Treasury spending caps and a minimum balance

Integration Risks

Risk	Mitigation
Chain compatibility	Thorough assessment phase
Community adoption	Early engagement, developer incentives
Resource constraints	Phased rollout, community contributions

Community Involvement

How to Participate

Developers

Build on Smart Engines once the testnet opens to developers.

Validators

Run validator nodes once the network opens to node runners.

Token Holders

Vote on protocol DAO proposals.

Community

Provide feedback, report issues.

Governance Milestones

Done: DAO framework built into the validators, with proposals and votes recorded on HCS
Done: protocol DAO created at genesis, with no human administrator
Planned: first community proposal votes, once the network is open
Planned: the HSuite DUNA’s Transitional Board hands over, narrows or sunsets, targeted by March 31, 2027
