FutureSight

FutureSight is a Rust terminal dashboard for monitoring Ethereum RPC health, recent block flow, fee pressure, and optional tx-pool activity across a host chain and a rollup.

What It Shows

• Connection state with stale and error signaling
• Current chain ID and best observed chain height
• Rollup tip sync status against the host tip, including block difference when out of sync and a red rollup feed box when unsynced
• Block age and chain halt alerts
• EIP-1559 fee telemetry, fee suggestions, utilization gauge, and fee trend sparkline
• Rolling block tape with gas usage and base fee context
• Optional tx-pool service health, cache counts, and recent transactions in the rollup panel

Build

Prerequisites: Rust toolchain. make is optional and only needed for the helper targets below.

git clone https://github.com/dylanlott/futuresight
cd futuresight
cargo build --release

Run

The built-in CLI defaults target the Parmigiana Signet environment.

cargo run

Show the full CLI surface:

cargo run -- --help

Tune refresh rate and history depth:

cargo run -- \
  --refresh-interval 3 \
  --max-block-history 40 \
  --block-delay-secs 90

Enable tx-pool telemetry:

cargo run -- \
  --txpool-url https://transactions.parmigiana.signet.sh

Disable tx-pool transaction lists while keeping tx-pool summary counts:

cargo run -- \
  --txpool-url https://transactions.parmigiana.signet.sh \
  --no-txpool-list

Use the Makefile wrappers:

make run
make dev
make parmigiana
make mainnet

Notes:

• cargo run uses the CLI defaults shown in the table below.
• make run falls back to the same Parmigiana endpoint defaults as the CLI, but existing shell env vars or make variable overrides still win.
• make parmigiana forces HOST_RPC_URL=https://host-rpc.parmigiana.signet.sh and ROLLUP_RPC_URL=https://rpc.parmigiana.signet.sh.
• make mainnet forces HOST_RPC_URL=https://rpc.flashbots.net and ROLLUP_RPC_URL=https://rpc.mainnet.signet.sh.
• make run RUN_ARGS="--no-txpool-list" is the Makefile path for flags that do not have env-var equivalents.

Configuration

Most runtime flags can also be set through environment variables.

Flag	Env	Default
--host-rpc-url	HOST_RPC_URL	https://host-rpc.parmigiana.signet.sh
--rollup-rpc-url	ROLLUP_RPC_URL	https://rpc.parmigiana.signet.sh
--txpool-url	TXPOOL_URL	https://transactions.parmigiana.signet.sh
--block-delay-secs	BLOCK_DELAY_SECS	60
--refresh-interval, -r	REFRESH_INTERVAL	2
--max-block-history	MAX_BLOCK_HISTORY	24
--txpool-max-rows	TXPOOL_MAX_ROWS	12
--no-txpool-list	none	false

Notes:

• --txpool-url powers the rollup panel's Flow Radar section.
• --txpool-url is a network-level tx-pool endpoint. For known Parmigiana and mainnet hosts, FutureSight auto-populates the watched host system contracts from Signet constants instead of taking a manual contract list.
• --no-txpool-list disables fetching transaction rows while keeping tx-pool summary requests enabled.

make dev is an alias for make watch. make watch requires cargo-watch.
