Feb 1, 2026

February 2026 provided solid backend and reliability improvements for the Stellar Disbursement Platform, with a focus on embedded wallet capabilities, security hardening, and CI stability. Delivered Embedded Wallet support, added integration tests, and fixed default enablement to ensure out-of-the-box functionality for new tenants. Implemented CAPTCHA/reCAPTCHA integration endpoints and flow updates to strengthen user verification. Stabilized end-to-end tests by removing Docker Compose build race conditions in TSS, and ensured long-term platform reliability through default feature enablement fixes, plus a default-enabled link shortener for new tenants to close migration gaps.

January 2026 backend-focused delivery for stellar-disbursement-platform-backend: delivered 3 key changes across features and bugs to harden validation, deprecate legacy provider UI, and streamline verification flow. Improvements include 1) robust multibyte ID error handling with utf8 rune-aware length checks; 2) soft-deletion of legacy Vibrant Assist wallet provider to clean /wallets; 3) conditional verification header bypass when verification type is None for embedded wallet. These changes enhance data integrity, user experience, and flexibility of disbursement flows, while updating tests and changelogs.

November 2025 — Stellar Disbursement Platform Backend: concise monthly summary focused on delivering business value and technical excellence. Key features delivered: - Embedded Wallet Verification Bypass: Enabled optional verification bypass for embedded wallets to streamline onboarding. Implemented tracking for wallet status (receiver_wallet_id, requires_verification), updated disbursement handling for non-verification paths, adjusted SendInvite flow, and added API gating and tests. Commits include 2bfc0555fa8accdd2676713d990cd45b8474752c (SDP-1877). - Single-Tenant Deployment Configurability and MFA Security Controls: Made SINGLE_TENANT_MODE loadable from environment (default false) to ensure safe startup; enabled proper MFA inheritance during single-tenant creation via CLI flags. Commits include 902a16b21dedce1d3511071a5efb46ed444ee13d (SDP-949) and 980a73f19948790081cffc1b9238f2b5aa3f1893 (SDP-950). Major bugs fixed: - Environment-driven startup correctness: Docker Compose now respects env SINGLE_TENANT_MODE, preventing unintended single-tenant mode. - MFA propagation correctness in single-tenant flow: CLI now forwards DISABLE_MFA to honor security settings. Overall impact and accomplishments: - Reduced onboarding friction for embedded wallets while maintaining verification governance and test coverage. - Increased deployment safety and security posture by clarifying tenancy modes and ensuring MFA settings propagate as configured. - Clear traceability to SDP tickets and commits, enabling faster reviews and production readiness. Technologies/skills demonstrated: - Backend API changes and database schema adjustments for wallet verification tracking. - DevOps/configuration: environment-driven feature flags, docker-compose adjustments, and CLI integration. - Security: MFA handling across tenancy modes. - Testing: added tests validating verification bypass path and related flows.

December 2024 focus was on reducing onboarding friction and improving API discoverability for Stellar developers in the stellar-docs repository. The main deliverable was the Anchor Platform Documentation Update, including API references for get_transaction and get_transactions RPC methods, plus comprehensive SEP 3.0 guides. This release also documented the setup, configuration, and SEP coverage (SEPs 6, 10, 12, 24, 31, 38) for the Anchor Platform 3.0 release. The work did not introduce production bugs but closed documentation gaps, enabling faster integrations and fewer support cycles. Commit history demonstrates a clear trace from API enhancements to the 3.0 release documentation.
