Month: 2025-09 — DefiLlama-Adapters: River protocol integration and Satoshi adapter refactor to align with River rebranding and asset updates. The work centers on refactoring the Satoshi protocol adapter to support River Inc. branding, updating event ABIs to accommodate new configuration structures, and renaming the nymList parameter to nymWithAssetList to better reflect its content. Processing logic was adjusted to directly use the provided asset lists, and River/Satoshi configurations were updated to include new asset and collateral addresses to reflect the integration of new assets and protocol evolution. This reduces integration risk, improves data accuracy, and establishes groundwork for future asset updates and protocol changes, with clean, maintainable code paths for asset-driven processing.

August 2025: Expanded DefiLlama-Adapters with two major features, enhancing TVL accuracy and data coverage across Satoshi and River protocols. Key achievements: - Smart Vault support and TVL tracking for Satoshi protocol: fetch total deposits from smart vaults, integrate into TVL, introduced a new ABI constant, and updated export configuration; bfBTC smart vaults added. - River protocol integration: add River Bitcoin address, update bitcoin-book helper, reflect River in Satoshi protocol index, and add River smart vault addresses/assets in River configuration. Other notes: - No major bugs fixed reported in this period. Technologies/skills demonstrated: - On-chain data integration, ABI management, and TVL calculation improvements - Cross-protocol integration (Satoshi bfBTC, River) - Adapter/configuration updates and version-control hygiene
