Summary
A fresh EVM Gateway node cannot sync past Cadence height ~88,226,267 because the mainnet26 spork access node (access-001.mainnet26.nodes.onflow.org:9000) is unreachable (gRPC connection failure). Alternative endpoints (access-002, access-003) also don't respond.
The gateway replays block events from genesis through each spork. It gets through mainnet25 fine but cannot cross into the mainnet26 range (heights ~88.2M–130.3M). Mainnet27 starts at ~130.3M, leaving a 42M block gap with no available access node.
This means no new EVM Gateway instance can fully sync from scratch without a workaround.
What we've tried
- Connecting to all known mainnet26 access node endpoints — all unreachable
- Confirmed mainnet25 sync completes successfully
- Confirmed mainnet27+ nodes are available and working
Why local gateway matters
We're running a local EVM Gateway to get low-latency price data for on-chain operations. The performance difference vs public RPC is significant:
| Metric |
Public RPC |
Local Gateway |
Per eth_call |
~150ms |
~14ms |
| Full scan cycle |
~4–8 sec |
~0.5–1 sec |
| Detect → submit |
~300–500ms |
~30–50ms |
Public RPC is ~10x slower, which means we can only compete on dislocations persisting multiple blocks. Anything closing in 1–2 blocks is missed entirely.
Request
Any one of the following would unblock us:
- Restore a mainnet26 access node (or document if this is permanently deprecated)
- Publish a pre-synced EVM Gateway DB snapshot that covers through mainnet26
- Provide an archive node serving the 88.2M–130.3M Cadence height range
Context
Per discussion in Discord with the Flow team: mainnet26 access node is confirmed deprecated, and there is currently no pre-synced DB snapshot or archive node covering this range. Filing this issue so there's a trackable request and others hitting the same wall can find it.
Environment
- EVM Gateway: latest release
- OS: Ubuntu 22.04 (Hetzner EX44)
- Sync method: replay from genesis through spork endpoints
