+# zeronet system deploy
+
+Full L1 system deployment on zeronet using `SystemDeploy.s.sol` from the sibling `contracts/` repo.
+
+
+## Steps
+
+### 0. Refresh genesis anchor values before executing
+
+`multiproofGenesisBlockNumber` and `multiproofGenesisOutputRoot` must point to a block that is still available in the proof node at the time of deployment. Refresh them immediately before running `make simulate` or `make deploy`:
+
+```sh
+BLOCK=$(cast rpc optimism_syncStatus --rpc-url https://base-zeronet-reth-proofs-donotuse.cbhq.net:7545 | jq -r '.finalized_l2.number')
+OUTPUT_ROOT=$(cast rpc optimism_outputAtBlock "$(printf '0x%x' "$BLOCK")" --rpc-url https://base-zeronet-reth-rpc-donotuse.cbhq.net:7545 | jq -r '.outputRoot')
+echo "multiproofGenesisBlockNumber: $BLOCK"
+echo "multiproofGenesisOutputRoot:  $OUTPUT_ROOT"
+```
+
+Update `deploy-config/zeronet.json` with the printed values before proceeding.
+
+### 1. Simulate (no broadcast)
+
+```sh
+make simulate
+```
+
+### 2. Deploy (broadcast via Ledger)
+
+```sh
+make deploy
+```
