op-interop-filter/v0.0.1

op-interop-filter: use dedicated port for admin RPC (#19083)

Change from route-based admin API (/admin with custom JWT handler) to a
dedicated port approach (like op-node's interop RPC).

Before:
  Port 9545 → supervisor API (public) + /admin (JWT via custom handler)

After:
  Port 9545 → supervisor API (public)
  Port 8546 → admin API (server-wide JWT)

New flags:
- --admin.rpc.addr: Address to bind admin RPC (empty = disabled)
- --admin.rpc.port: Port for admin RPC (default: 8546)

Admin RPC is disabled by default and requires --admin.jwt-secret when enabled.

op-batcher/v1.16.4

This is a recommended release containing:

• A feature where the batcher can choose a smarter, dynamic blob tip cap to use, based on recent market activity on L1.
  The feature can be enabled by setting OP_BATCHER_TXMGR_BLOB_TIP_CAP_DYNAMIC=true. By default, the existing static blob tip cap will be used. For more details, see #18981 and #18386.
• Several bugfixes and stability improvements.

Tip

If you use proxyd for the batcher's L1 connection, we recommend upgrading to proxyd/v4.25.0 (this contains a non-critical bugfix and avoids noisy warning logs being emitted by the batcher).

Changelog

• 018f5ae chore: update fees depositor address and min withdrawal amounts (#18736)

op-contracts/v6.0.0-rc.2

Overview

This release introduces Revenue Sharing, an opt-in mechanism for configurable distribution of L2 transaction fees between Optimism and chain operators.

This release does not modify any L1 contracts, and thus is being made as an incremented -rc on the existing v6.0.0 tag.

---

New Contracts

• FeeSplitter
  L2 predeploy: 0x420000000000000000000000000000000000002B
  Orchestrates fee collection from vaults and distributes funds to configured recipients.

• SuperchainRevSharesCalculator
  Calculates Optimism’s share as: max(2.5% of gross revenue, 15% of net revenue)

• L1Withdrawer
  Automatically bridges collected shares to L1 once a threshold is reached.
  (Optimism uses this for its share of fees.)

• FeesDepositor (L1)
  Receives bridged fees and deposits them once the threshold is reached
  (for Optimism, this deposits into OPM).

---

Updates

• FeeVault

  • Added flexible configuration via:
    • setRecipient()
    • setWithdrawalNetwork()
    • setMinWithdrawalAmount()

• Added DeployFeesDepositor deployment script

• Added Genesis flow support to enable revenue sharing on new chain deployments
