+# 061 betanet-rev-share: RevShare Upgrade and Setup for Betanet
+
+Status: [READY TO SIGN]
+
+## Objective
+
+Upgrade proxies and setup RevShare contracts for the RevShare Betanet chain. This task:
+
+1. Deploys all needed contract implementations:
+   - FeeVaults
+   - FeeSplitter
+   - L1Withdrawer (pointing to the FeesDepositor on L1)
+   - RevShareCalculator (pointing to the L1Withdrawer and the ChainFeesRecipient)
+2. Upgrades the fee vault proxy implementations (SequencerFeeVault, BaseFeeVault, L1FeeVault, OperatorFeeVault) on the Betanet L2
+3. Sets FeeSplitter predeploy to point to the new FeeSplitter implementation and initializes it with the RevShareCalculator address
+
+Target chain:
+
+- revshare-beta-0 (chainId: 420120033)
+
+## Simulation & Signing
+
+Simulation commands for each safe:
+
+```bash
+# For stacked simulation (recommended for validation):
+just simulate-stack sep 061-betanet-rev-share
+
+# For individual simulation:
+cd src/tasks/sep/061-betanet-rev-share
+SIMULATE_WITHOUT_LEDGER=1 just --dotenv-path "$(pwd)"/.env --justfile ../../../justfile simulate
