Injectived Startup Flag Changes for v1.20.0

This note summarizes injectived start flag changes between v1.19.0 and v1.20.0. All node runners should review their startup scripts, Helm charts, systemd units, or Kubernetes manifests before upgrading.

Recommended Upgrade Checklist

1. Remove flags that no longer exist.
2. Rename metrics and ChainStream flags if you use them.
3. Pin any changed defaults if your node depends on the old behavior.

Long-Term Configuration Recommendation

Prefer setting persistent node configuration in the appropriate config file:

• Use app.toml for application-level settings such as API, gRPC, JSON-RPC, pruning, metrics, ChainStream, EVM, and Injective websocket configuration.
• Use config.toml for CometBFT settings such as P2P, RPC, consensus, and mempool configuration.

Startup flags should be treated as temporary overrides for testing, emergency operations, or short-lived rollout changes. They should not be used as the permanent replacement for values that belong in app.toml or config.toml. Keeping long-lived settings in config files makes validator behavior easier to audit, reduces upgrade risk when flags are renamed or removed, and keeps startup commands stable across releases. The template app.toml and config.toml files for the v1.20.0 tag can be found at the bottom of this file.

Renamed or Replaced Flags

Update any startup configuration that still uses the old flag names.

v1.19.0 flag	v1.20.0 flag	Notes
--metrics-enable-metrics=false	--metrics.metrics-enabled=false	Same default.
--metrics-enable-tracing=false	--metrics.tracing-enabled=false	Same default.
--metrics-endpoint=localhost:4317	--metrics.endpoint=localhost:4317	Same default.
--metrics-insecure=false	--metrics.insecure-endpoint=false	Same default.
--metrics-export-interval=10s	--metrics.export-interval=10s	Now parsed as a duration and used by metrics export.
--metrics-stuck-func=0m	--metrics.stuck-func-timeout=0s	Same effective disabled default.
--trace-flight-recorder-threshold=0	--metrics.flight-recorder-threshold=0s	Same effective disabled default.
--log-color=true	--log-no-color=false	Behavior is inverted.
--chainstream-server=""	--chainstream.server=""	Same default.
--chainstream-buffer-cap=100	--chainstream.buffer-cap=100	Same default.

--chainstream-server-ping-response-timeout=40	--chainstream.server-ping-response-timeout=40	Same default.

Added Flags (Informational. No change needed as these values will be picked from the config files as usual)

These flags did not exist as injectived start flags in v1.19.0.

v1.20.0 flag	Default	Notes
--app-db-backend	""	Empty value falls back to the CometBFT DB backend.
--index-events	[]	Controls event indexing for CometBFT. Empty means all events are indexed.
--chain-id	injective-1	New on start
--injective-websocket.address	""	Empty value disables the Injective websocket server.
--injective-websocket.max-open-connections	0	Unlimited.
--injective-websocket.read-timeout	10s	HTTP read timeout.
--injective-websocket.write-timeout	10s	HTTP write timeout.
--injective-websocket.max-body-bytes	1000000	Maximum allowed request body size.
--injective-websocket.max-header-bytes	1048576	Maximum allowed header size.
--injective-websocket.max-request-batch-size	10	Maximum JSON-RPC requests per batch.

Removed Flags

Remove these from startup scripts before running v1.20.0.

Removed flag	Previous default	Replacement
--with-comet	true	None. In-process CometBFT startup is now the supported path.
--with-tendermint	Alias for --with-comet	None.
--address	tcp://0.0.0.0:26658	None for normal validator startup.
--transport	socket	None for normal validator startup.
--pruning-keep-every	0	None. Use --pruning, --pruning-keep-recent, and --pruning-interval.
--multistore-commit-sync	false	None. This flag was registered in v1.19.0 but not consumed by Injective startup code.

Same Name, Changed Default or Type

If your deployment relied on the old default, set the old value explicitly.

Flag	v1.19.0	v1.20.0	Suggested validator action
--minimum-gas-prices	""	160000000inj	Pin explicitly if you require a different minimum gas price.
--pruning	default	nothing	Pin --pruning=default if you do not want archive-style behavior.
--pruning-keep-recent	uint64(0)	string "0"	Usually no action; type changed for config parsing.
--pruning-interval	uint64(0)	string "0"	Usually no action; type changed for config parsing.
--iavl-cache-size	int(500000)	uint64(781250)	Pin old value if memory/cache sizing depends on it.
--api.enable	false flag default	true flag default	Pin --api.enable=false if the REST API must remain disabled.
--api.swagger	false flag default	true flag default	Pin --api.swagger=false if Swagger must remain disabled.
--api.address	tcp://localhost:1317	tcp://0.0.0.0:10337	Pin old address if exposing the API is not intended.
--api.enabled-unsafe-cors	false flag default	true flag default	Pin false if CORS must remain disabled.
--json-rpc.api	unset / nil	[eth, net, web3, inj]	Pin explicitly if you require a different namespace set.
--json-rpc-debug.api	[debug]	[eth, debug, inj]	Pin explicitly if debug RPC is enabled and should stay debug-only.
--json-rpc.max-open-connections	uint(0)	int(0)	Usually no action; value remains unlimited.
--json-rpc.return-data-limit	uint(512000)	int64(512000)	Usually no action; value is unchanged.
--json-rpc-debug.max-open-connections	uint(0)	int(0)	Usually no action; value remains unlimited.
--json-rpc-debug.return-data-limit	uint(10485760)	int64(10485760)	Usually no action; value is unchanged.
--log-level	info	""	Pin explicitly if you require a specific log level.
--log-format	plain	""	Pin explicitly if you require plain or json.

For --api.*, note that generated Injective app.toml defaults were already set to enabled in v1.19.0; the notable change is the effective CLI flag default used by injectived start.
