PIP-48 l Update PAR Bridging Module DVNs Configuration

JeanBrasse · April 21, 2025, 1:06pm

Summary:

The proposal aims to update the PAR bridging module Decentralized Verifiers Network (DVNs) configuration.

Context

Tunnel, the Parallel Bridging Module, is now in production for PAR on Ethereum, Polygon PoS and Fantom since November 2024.

However, since the beginning of January, one of the chosen DVNs, Polyhedra, has stopped supporting Fantom. Although this poses no risk to the protocol thanks to LayerZero’s architecture, it is now impossible to bridge PAR to and from Fantom. We therefore propose to update the DVNs of the PAR Bridging Module.

Rationale:

We propose to remove Polyhedra from required DVNs and replace it with Nethermind, which is currently an optional DVN. Nethermind would be replaced by BitGo as an optional DVN. We also propose to update the bridge limits.

Proposed new parameters:

Ethereum:

DVNs: (2 of 1 of 2)
- Required: 2
  - LayerZero Labs
  - Nethermind
- Optionals: 1 of 2
  - BitGo
  - Google Cloud

- Daily: 50,000.00
- Global: 500,000.00
Burn Limits:
- Daily: 50,000.00
- Global: 500,000.00
Fees:
- Rate: 0.00%
Isolate Mode:
- No

Polygon PoS:
