Haiyizxx
Haiyi contributed to the axelarnetwork/axelar-core repository by delivering core blockchain features and stability improvements over five months. They engineered upgrades to the Cosmos SDK and module dependencies using Go and Protocol Buffers, ensuring reproducible builds and streamlined future maintenance. Haiyi enhanced cross-chain reliability by refining IBC transfer logic and introduced a fee-burning mechanism in the distribution module to support sustainable tokenomics. Their work included modular architecture improvements, targeted permissions migrations, and observability enhancements through new API endpoints. By focusing on backend development, dependency management, and protocol integration, Haiyi delivered robust, maintainable solutions that improved reliability and operational transparency.

Feb 1, 2025February 2025 (axelarnetwork/axelar-core): Delivered core distribution improvements, upgraded dependencies for security and performance, and completed a targeted permissions migration. Highlights include a Custom BeginBlocker integration for the distribution module with a wrapped keeper and a parity test against the Cosmos SDK to ensure correct token allocations and proposer rewards; a focused migration granting burner permissions to the distribution module account; CosmWasm/wasmvm upgrades with removal of temporary replacements and related cometbft updates; and a clarity improvement by renaming FeeBurnedEvent to FeesBurned. These changes enhance reliability of token distributions, reduce security risk, and streamline future maintenance while preserving feature parity and delivering measurable business value.

Jan 1, 2025Concise monthly summary for 2025-01 focusing on business value and technical achievements in axelar-core. Delivered a tokenomics upgrade by burning transaction fees in the distribution module, recalibrating fee allocation to burn a significant portion of transaction fees while continuing to allocate the community tax to the community pool. This change reduces circulating supply and strengthens treasury sustainability. Major commit: 65631173bd08ba0ce7df0a46d5dcf72b21f4c5a8 with message 'feat(distribution)!: custom fee allocation (#2231)'. No other bugs fixed this month; progress centered on feature delivery and safe rollout of the new fee-burn mechanism. Technologies demonstrated include Golang-based module development within Cosmos SDK, changes to the fee distribution logic, and release-ready feature design for governance and treasury outcomes.

Nov 1, 20242024-11 monthly summary for axelar-core (axelarnetwork/axelar-core). Delivered stability, modularity, and cross-chain reliability improvements across the core codebase. Key items include dependency pinning for Wasmd to a specific Axelarnetwork fork to ensure reproducible builds and maintainable dependencies; introduction of FilteredModuleManager to selectively register module routes/services and exclude non-core modules (e.g., vesting) from core functionality; migration of pre-initialized module accounts to proper ModuleAccounts to guarantee correct bootstrap or on-demand creation; and a fix to the IBC transfer retry path that routes all transfers through the AxelarIBCAccount with aligned sender handling and escrow/retry logic. These changes reduce upgrade risk, minimize surface area for bugs, and improve cross-chain transfer reliability. Technologies demonstrated include Go module management, modular architecture, IBC integration, and account migrations. Business value: more predictable deployments, safer upgrades, and more robust cross-chain operations.

Oct 1, 2024Month: 2024-10 — axelarnetwork/axelar-core delivered two core improvements: a bug fix for refund logic from escrow on IBC packet failure, and an observability enhancement via API extension for failed transfers. The refund bug fix adds a new function refundFromAssetEscrowAddressToIBCAccount and updated tests to validate the refund mechanism after upgrade (commit fe8587aceac3887f265bb22b7a35e99710cbaea7). The observability enhancement introduces a new transfer state TRANSFER_STATE_FAILED and a dedicated API endpoint to query failed transfers, plus a refactor to archive failed transfers for better lifecycle management (commit 31dd11d4b778803e981f3954fa60a20422f41734). This combination reduces asset loss risk, improves troubleshooting, and enhances operator visibility during IBC transfer failures. Overall impact: higher reliability, faster issue diagnosis, and stronger auditability. Technologies/skills demonstrated: Rust/Cosmos SDK development, IBC transfer mechanics, OpenAPI design, testing/upgrading, and API-first observability.
