Migrate Cabal OPbridge to IBC

Original Proposal Text

## 1. TL;DR This proposal aims to migrate Cabal from the OP bridge to IBC, enabling instant bridging without a finalization period. ## 2. Proposal Details This proposal will enable the OP Bridge to use IBC internally for instant bridging and allow IBC to mint existing OP bridged tokens rather than IBC vouchers. **About the Rollup** - Protocol Name: Cabal - Protocol Type: DeFi | **Rollup name** | **Bridge ID** | L1Denom | IBC Channel ID | IBC Port ID | | --- | --- | --- | --- | --- | | Cabal | 42 | `uinit` | `channel-97` | `transfer` | **Rationale** Cabal was initially launched with an OP bridge that requires a 1-day finalization period for withdrawals from the Cabal rollup to Initia L1. To provide users with an instant bridging experience, we propose migrating Cabal to use IBC (Inter-Blockchain Communication) protocol instead, as has already been done for other rollups. Benefits of this migration: - Instant bridging without finalization delays - Improved user experience for the vault ecosystem - Seamless integration with existing OP bridged tokens The migration will configure the OP bridge to utilize IBC internally, enabling instant bridging while maintaining compatibility with previously minted OP bridged tokens. Instead of creating new IBC vouchers, the system will mint the existing OP bridged token format. If this proposal is approved, users will be able to bridge INIT tokens between Cabal and Initia L1 instantly through IBC, eliminating the current 1-day withdrawal period. Withdrawals initiated before the migration remain claimable through the existing Withdrawal status page. **Implementation Details** The technical implementation will connect Bridge ID 42 (Cabal) with IBC channel-97 using the transfer port, allowing seamless migration from the OP bridge infrastructure to IBC while preserving token compatibility. On execution, the INIT held in the OP bridge escrow is moved to the channel-97 IBC escrow. ## 3. Timelines 1. September 9th - Onchain Vote begins 2.
