By Stellar Integration in Adamik API
Unified blockchain API helping developers integrate Stellar in days, not weeks, with major read/write operations.
After years of integrating 50+ blockchains at Ledger—including Stellar��we experienced firsthand the pain of learning each protocol's quirks, maintaining separate codebases, and watching months slip by for each integration. Adamik is the unified API we desperately wished for back then: one interface, consistent across all chains.
With this proposal, Adamik's unified blockchain API will add full Stellar support, enabling developers to:
Query XLM/asset balances and transaction history via standard REST endpoints
Build and encode Stellar transactions (transfers, trustlines, memos) using our universal format
Integrate with enterprise key management (Ledger, Fireblocks, Turnkey)
Impact: Existing Adamik users can add Stellar in 48-72 hours. New developers bypass Stellar-specific complexity entirely. Stellar will receive ongoing maintenance and protocol updates as part of Adamik's standard operations, no additional funding required.
Maybe in the future, but not in this submission
$74.8K
Technical Success:
Full Stellar support live on mainnet/testnet with feature parity
Achieve 99.9% uptime for Stellar endpoints
Adoption Metrics:
10+ active developers using Stellar endpoints within 3 months
10,000+ Stellar API calls within first month
Ecosystem Impact: Enable 3+ wallets/fintechs to add Stellar support
Developer Experience: 90% reduction in Stellar integration time (days vs weeks)
Timeline Commitment: Complete integration within 18 weeks of grant approval
Stellar integration will be available to all existing Adamik API users (250+ developers across 60+ chains). Our developer-first approach includes:
Comprehensive Stellar documentation in our API reference
Integration tutorials at tutorial.adamik.io
Open-source Stellar support in Adamik MCP Server for AI-assisted development
Free Stellar API calls for first 3 months to encourage adoption
Direct outreach to existing enterprise clients needing Stellar support
Adamik is already powering multichain access for leading Web3 companies including Ledger Enterprise, NGrave, and OpenWallet.
These platforms rely on Adamik to integrate multiple blockchains through a single, standardized API, drastically reducing time-to-market and engineering overhead.
Since January 2025, we’ve onboarded 4 new enterprise clients ahead of our go-to-market push. We’ve also partnered with MPC providers Sodot and Turnkey to offer a flexible, signer-agnostic stack that serves as a practical alternative to Fireblocks.
Our API now processes 500k+ calls daily, with growing adoption among wallets, staking providers, and institutional applications.
This traction demonstrates strong demand for non-custodial, multichain access and Stellar will immediately benefit from being included in this rapidly growing network.
Description: Implement core Stellar read operations and basic transaction encoding
Deliverables:
Account XLM Balance Retrieval (User Story #1) - $7,000
Pubkey to Address Conversion (User Story #2) - $6,000
Chain Details Endpoint (User Story #4) - $6,000
Address Validation (User Story #5) - $6,000
XLM Transfer Encoding without signing (User Story #3) - $10,000
Completion Metrics: All 5 core endpoints functional with internal testing, documented API responses, unit test coverage >90%
Budget: $35,000
Timeline: 6 weeks
Description: Complete Stellar feature set on testnet including assets and transaction history
Deliverables:
Fee Estimation and Minimum Balance Logic (User Story #6)
Transaction Details Retrieval (User Story #7)
Stellar Digital Asset Transfer Encoding (User Story #8)
Trustline Management (User Story #9)
Send Max Feature Implementation (User Story #10)
Complete testnet integration with partner validation
Completion Metrics: Full Stellar testnet support, partner testing completed, comprehensive documentation published
Timeline: 10 weeks (No budget - as per Stellar guidelines)
Note: While this tranche requires significant development work, SCF guidelines allocate no budget to testnet phases. The value of this phase is to prepare the groundwork for mainnet phase (tranche 3).
Description: Deploy production-ready Stellar support with reliable Horizon infrastructure, monitoring, automated testing, and full integration into Adamik's 60+ chain ecosystem
Deliverables:
Production Horizon infrastructure setup and optimization - $10,000
Comprehensive monitoring and alerting systems - $8,000
Automated testing and CI/CD pipeline integration - $10,000
Full ecosystem integration with existing 60+ chains - $10,000
Production documentation and developer tutorials - $1,800
Demo application at tutorial.adamik.io
Completion metric: Stellar mainnet live on api.adamik.io with documentation, tutorials, and demo app integration at tutorial.adamik.io
Timeline: 18 weeks from approval
Budget: $39,800
By the end of tranche 3, Stellar will be fully usable in production environments alongside our 60+ supported chains, with full documentation, integration guides, and tutorials.
The Adamik team is composed of blockchain infrastructure veterans with deep expertise in protocol integration. Our core team previously led and delivered multiple protocol integrations at Ledger, including the Stellar (XLM) integration for both Ledger Live and Ledger Enterprise, as well as several reviews on the Ledger Stellar application running on the hardware wallets.
Fabrice Dautriat (CEO) – Former Head of Developer Ecosystem at Ledger, with 6 years at the company overseeing integrations across hardware, software, and infrastructure.
Hakim Aammar (CTO) – Former Technical Lead of Ledger’s Blockchain team, responsible for Stellar’s protocol integration and tooling.
Roman Beyon Grataroli (CCO) – Former Blockchain Product Lead at Ledger, focused on partnerships and developer engagements.
Henri Ly (Lead Developer) – 4 years at Ledger as a Blockchain Integration Engineer, directly involved in Stellar compatibility and hardware wallet support.
Mourad Kejji (Blockchain Engineer) – Expert in multi-chain infrastructure and EVM compatibility.
We bring years of hands-on experience working with the Stellar network and are uniquely positioned to expose Stellar’s capabilities through a standardized, production-grade API used by institutions.
