Edge & Node March / April 2026 Update

Research & Development Core Team Updates
1

:astronaut: Executive Summary

Edge & Node marked a major protocol milestone this period with the deployment of the Rewards Eligibility Oracle (REO) contract to Arbitrum One, alongside steady momentum on Indexing Payments (DIPs), for which GIPs are now published and a smart contract audit is underway. On the product side, Explorer received multiple Horizon-related delegation fixes and Studio saw security and stability improvements for Safe wallet users. Graph Node moved on to release v0.42.0, which includes several new experimental features, improvements to existing tooling, and bug fixes. Content and community engagement deepened through new distribution channels, technical insights, podcast episodes, a user-contributed series, plus explainers on enterprise certifications and regulations.

:tada: Notable March Accomplishments

Protocol

  • Completed the migration of Upgrade Indexer allocations to Horizon!

  • Production Rewards Eligibility Oracle (REO) contract deployed to Arbitrum One, with a newly written off-chain oracle node now live

    • The new node replaces a prior BigQuery data pipeline dependency with direct consumption of gateway query data from a Kafka topic, improving both reliability and operational simplicity

    • Testing is in progress; activation is pending completion of the audit and a governance vote

  • Steady progress on Indexing Payments (DIPs)

    • Published GIP-0087

    • Auditing the updated DIPs contracts with Trust Security

    • Progressing on indexer-agent integration with the DIPs contracts

    • New subgraph to track DIPs deployed

    • Improvements landed on both the indexer and gateway (dipper) sides of the stack, as well as the IISA

    • This work is on the path to bring Amp onto the network, as DIPs will be part of the Amp service

  • Released indexer-agent v0.25.6 with resize and present POI actions, batched RAV collection, and support for long-lived allocations

  • Supported an external audit of indexer-rs components with Trust Security

  • Fixed a security report in the legacy token distribution (vesting) contracts that would have allowed early access to locked tokens in revocable vesting contracts (no funds at risk)

Graph-Node

  • Released many new experimental features with v0.42.0, including Amp-powered subgraphs, SQL query interface within GraphQL, fully async store and database interactions, RPC request compression, and ability to query the current (partially filled) aggregation bucket

  • Added new graphman capabilities (experimental Parquet dump/restore)

  • Expanded gnd as a drop-in replacement for graph-cli

  • Included improvements such as optimized log filter matching and trigger allocation, reduced unnecessary entity clones during block processing, deadlock prevention under heavy load, and logging of deployment hashes when subgraphs are removed

Explorer & Studio

  • Explorer

    • Reinstated L1 mainnet protocol support so users can undelegate and withdraw leftover delegations post-Horizon activation

    • Fixed delegated stake display to include both legacy and Horizon staking ID formats

    • Corrected unallocated delegation token calculation and thawing remainder period formatting

    • Added Token API banner alongside Substreams on the Subgraphs homepage

  • Studio

    • Security improvement on SIWE (sign in with Ethereum) signing message verification

    • Migrated querying stack to backend upgrade-indexer subgraph indexing logs

    • Fixed published subgraph status reconciliation issue affecting Safe user wallets

Content & Community

:telescope: What’s Next

  • Activate DIPs and the Rewards Eligibility Oracle following audit completion and governance approval

  • Continue the work to bring Amp to The Graph Network

  • Money 20/20 Bangkok
