Epoch 21 Echelon IBC Bridge Migration Proposal

Proposed Update

Migrate Echelon bridging from the OP Bridge to IBC to enable instant transfers between Echelon and Initia L1.

Motivation

  • The current OP Bridge enforces a withdrawal finalization period.

  • IBC enables instant bridging, which is critical for money market UX.

Current State

  • Bridging via OP Bridge

  • Withdrawal delay

Proposed Change

  • Use IBC for Echelon ↔ Initia L1 transfers

  • Remove withdrawal finalization delay

  • Mint existing OP-bridged tokens, not IBC vouchers
