proxyd /etc/proxyd/proxyd.toml: ws_method_whitelist, response_timeout_seconds, out_of_service_seconds, max_latency_threshold
- Changelog: https://github.com/ethereum-optimism/infra/blob/main/proxyd/CHANGELOG.md
- Config: https://github.com/ethereum-optimism/infra/blob/main/proxyd/config.go
- Releases: https://github.com/ethereum-optimism/infra/tags
Features:
- Whitelists RPC methods (ws_method_whitelist)
- Routes RPC methods to groups of backend services
- Round-robin Load balance requests across backend services
- Automatically retries failed backend requests
- Cache immutable responses from backends
- Provides metrics to measure request latency, error rates
Consensus related:
- Track backend consensus (latest, safe, finalized blocks), peer count and sync state
- Re-write requests and responses to enforce consensus
- Applies rate limiting (
SenderRateLimitConfig) on a per-sender basis to avoid being bombarded with signed transactions causing a DOS (Denial of Service) of the sequencer (Optimism Censorship Bug Disclosure)
