Overview

GasyardGateway is a cross-chain bridge contract that facilitates asset transfers between different blockchain networks. The contract handles token deposits on the source chain and coordinates with solvers to execute token releases on destination chains. Version 3 builds upon the robust foundation of V2 while introducing enhanced features for better tracking, integration capabilities, and operational flexibility.

We are still building on top of Intents mechanism but we introduce a new solving layer to maximize profits on solver, reduce risks on solver and rebalance better amongst solver

Version V3 is more optimised towards solver and adds functionality to pass additional data along with intents useful for General Message Passing

Removed the Escrow system in V3 so Refunds are processed via refund pool automatically

Key Improvements in V3

  1. Enhanced Metadata Support: V3 adds support for arbitrary data to be included in bridge transactions, allowing for better tracking and integration with external systems.
  2. Partner Integration: The additional data parameter can be used to identify partners, track referrals, or store application-specific data.
  3. Improved Event Transparency: Events now include all relevant transaction data, making it easier for indexers and off-chain services to track and process bridge transactions.
  4. Unchanged Security Model: V3 maintains the same robust security model as V2, with no compromise on the contract's security features.
  5. Removed Unlocks and Refunds: These are taken care by RefundPool individually if intent can’t be fulfilled

V2 vs V3: Key Improvements

30%+ Fee Reduction: Significantly lower transaction costs compared to V2

Dynamic Token-Specific Fees

: Customized fee structure based on asset type

Reduced Solver Risk: Solvers now receive payment in USDC-pegged tokens no need to unlock

Masked Private Transactions: Ability to add privacy on top of your transactions
