Wanchain Bridge

What is Wanchain

Wanchain enables secure cross-chain interoperability between EVM and non-EVM chains, including VeChain.

In veSave, Wanchain is responsible for bridging USDC from Ethereum (Sepolia) to VeChain.

Wanchain API

Wanchain provides an HTTP API for generating cross-chain transaction data. This includes:

• Filling in bridge parameters

• Performing token allowance checks (ERC-20)

• Returning a complete transaction payload for user signing

veSave uses the Wanchain Bridge to transfer USDC from Ethereum to VeChain. This cross-chain flow enables users to deposit assets on Ethereum and interact with DeFi yield opportunities on VeChain.

Stargate 2.0

Stargate is a liquidity transport protocol built for cross-chain DeFi. The protocol enables:

• Better gas optimization

• Modular architecture for protocol upgrades

• Enhanced reward and staking logic

• Cross-chain composability for yield farming

Stargate on VeChain integrates with the SDK to let users stake VET into liquidity pools and earn passive rewards.

In veSave:

• After swapping USDC → VET, the app calls the Stargate staking contract

• The user's VET is staked into a liquidity pool to begin earning rewards
