Edge & Node - February / March 2026

Research & Development Core Team Updates
1

:woman_astronaut: Executive Summary

Edge & Node made strong progress in February across core protocol work and production readiness, with increased momentum on Indexing Payments (DIPs) and continued validation of key components like the Rewards Eligibility Oracle. On the indexing side, graph-node v0.41.2 shipped meaningful reliability and data integrity improvements. In Amp, engineering focused on standardization and operability, including a canonical extractor template and new Admin API endpoints for lifecycle operations. Rounding out the theme of production readiness, ampersend added x402 v2 support with runtime version routing and simplified client creation. Read on for greater detail on the above and more.

:tada: Notable February Accomplishments

Protocol

  • Accelerating communication and documentation for Indexing Payments (DIPs)

  • Testing REO (Rewards Eligibility Oracle) on testnet and fixing bugs as needed

Graph-node

  • Released v0.41.2

    • RPC error handling: Expanded deterministic RPC error handling to cover Reth and Erigon edge cases

    • Data integrity: Fixed rewind/truncate targeting the wrong deployment, batch write memoization bug, and entity corruption after rewinding pruned subgraphs

  • Many improvements will ship with the next release, see details under What’s Next

Amp

  • Canonical extractor template: Solana, Firehose, and EVM RPC extractors all restructured to match a common template

  • Solana correctness: Proper blockhash pre-fetching, configurable commitment level, strictly increasing block numbers

  • Backup & restore: Restore workflow built out with single-table restore, revision restore, and namespace-prefixed object storage paths

  • Admin API enhancement: new endpoints for create, delete, truncate, and restore_revision

ampersend

  • Made several changes for production readiness:

    • Added x402 v2 protocol support in the HTTP client adapter, with runtime detection and routing between v1 and v2

    • Switched default network from Base Sepolia to Base mainnet

    • Simplified createAmpersendHttpClient so it can infer chain ID and auto-create the x402 client

:telescope: What’s Next:

  • New smart contract audit slated for early-mid March

  • Plans to ship graph-node version(s) with aggregation queries, a mock-based subgraph test runner, operational improvements, and dependency cleanup

  • EthCC, Digital Assets Conference, and promoting the intersection of AI and blockchains at The House
