Last week update is here: #3682

Current Focus

• Indexer for Explorer 0.2 release happened! 🎉 Kudos to @khorolets
  • Explorer has a version using Indexer for Explorer under https://indexer.explorer.mainnet.near.org
  • Wallet confirmed that they are unblocked by Indexer for Explorer to implement new features accurately
• Accurate circulating supply computation is getting implemented by @khorolets (we hit some corner cases and it seems that our estimate is much higher than the projected value, so we are investigating that)
• Addressed RosettaRPC blockers by @frol
  • Timeouts are cleared up
  • Construction API is almost working (even though the Construction API works fine, rosetta-cli cannot confirm that the transaction has landed due to the discrepancy between the transaction hash naming on the Data API side - needs a small fix on nearcore side)
• Exposed fetch contract binary JSON RPC method implemented by @ailisp in feat(rpc): rpc query contract code deployed #3714
• Landed Borsh no-std support! Add no_std support borsh#108 Kudos to @snjax and @voidxnull for implementing it!
• Structured Errors in JSON RPC / view-client discussed with @bowenwang1996 and @volovyk-s -- needs the first step implemented in the view-client

Plans

• Expose new JSON RPC methods to:
  • fetch receipt info by receipt id
  • fetch epoch information
• Finish reorg of Borsh project: @frol

Discussions

• JSON RPC "Bad Gateway" issue is getting debugged and addressed by @bowenwang1996
