Mission: Make Bitcoin programmatically accessible to every developer and AI agent — with fee intelligence that saves real money on every transaction.
Q2 2026 (Apr–Jun): Foundation & Adoption
Indexer Expansion
- Full address balance + transaction history indexing (mainnet)
- UTXO set queries by address with pagination
- Historical fee data API (hourly/daily aggregates going back 1 year)
- Block reward + subsidy tracking endpoints
Developer Experience
- Official Python SDK with typed models and async support
- JavaScript/TypeScript SDK (npm package)
- Interactive API playground improvements (saved queries, code generation)
- Comprehensive API reference documentation site
MCP Ecosystem
- bitcoin-mcp v1.0 release with stable tool interface
- 10+ additional MCP tools (PSBT construction, multi-sig support, Lightning invoice decoding)
- MCP resource templates for common agent workflows
Q3 2026 (Jul–Sep): Network Support & Intelligence
Multi-Network
- Signet support (full API parity with mainnet)
- Testnet4 support
- Network-aware fee recommendations (different strategies per network)
Advanced Fee Intelligence
- Fee prediction model (ML-based, 1hr/6hr/24hr forecasts)
- Historical fee percentile API (what fee would have confirmed in X blocks, Y days ago)
- Fee savings calculator with historical backtesting
- Mempool trend analysis (congestion forecasting)
Security & Reliability
- PSBT construction and analysis endpoints
- Multi-sig wallet support endpoints
- 99.9% uptime SLA for hosted service
- Geographic redundancy (multi-region deployment)
Q4 2026 (Oct–Dec): Ecosystem Integration
Protocol Tools

- Runes protocol support
- OP_RETURN data indexing and search
Agent Identity (BAIP Integration)
- BAIP-1 identity verification endpoints
- Agent-to-agent payment verification via Lightning
- Attestation validation API
- Agent capability discovery endpoints
Community & Governance
- Public development roadmap with community voting
- Contributor bounty program
- Monthly development reports
- Plugin/extension system for community-built endpoints
Q1 2027 (Jan–Mar): Scale & Sustainability
Performance
- Sub-100ms response time for all cached endpoints
- WebSocket v2 with granular subscription topics
- Batch API for multiple queries in single request
- CDN-cached static data endpoints
Ecosystem Growth
- Rust SDK
- Go SDK
- Docker one-click deployment (compose + node + API)
- Kubernetes Helm chart
Sustainability
- Self-sustaining hosting via Pro tier revenue
- Open governance model (community advisory board)
- Annual transparency report (usage, costs, development hours)
