Bridge

Introduction

The Bridge just transfers tokens from a user to another wallet (could be themselves) on a different chain. Since no call data is involved, no target contract is needed.

How does the Bridge work?

BIM Exchange aggregates various asset bridges and decentralized exchanges (DEXs) into a unified meta-bridge, selecting the most suitable route based on criteria like cost, speed, or security. By integrating DEXs and aggregators, users can seamlessly transfer tokens between different blockchains, such as swapping token A on chain X for token B on chain Y. Built on Bungee, BIM Exchange supports two bridging methods:

• Single Transaction Bridge: Enables one-step token transfers between chains, though limited by supported tokens on the destination chain.

• Multi-Transaction Bridge: Allows more flexible bridging by combining swaps and transfers across chains.

Architecture and Operations

BIM Exchange’s infrastructure consists of on-chain smart contracts and an optional off-chain component:

• On-Chain: Bungee smart contracts manage token transfers across chains.

• Off-Chain: A backend quoting engine and API determine the optimal bridging routes, working with liquidity data from DEXs.

The process involves multiple steps, including generating quotes, approvals, and executing transactions for a seamless bridging experience. For more details, refer to the contract, backend architecture and lifecycle of bridging session.
