ABOUT VIA BRIDGE

VIA Bridge is a cross-chain gateway into the VIA Network that turns your assets into productive liquidity.

VIA Bridge connects Ethereum to VIA, turns bridged stablecoins into yield-bearing vTokens, so your capital starts working the moment it lands on VIA. vTokens can be used across VIA’s ecosystem to earn additional yield on top of base yield.

VIA Bridge also connects Bitcoin to VIA, unlocking features that make your BTC more useful on VIA (coming soon!)

Ethereum bridged assets earn yield through VIA’s vault system, secured by Bitcoin and finalized through a decentralized zero-knowledge verifier network.

VIA uses simple, secure, battle-tested yield strategies behind the scenes, without loops, leverage, or complex actions required from the user. You deposit once, and your vTokens keep working for you.

Bridge assets from Bitcoin or Ethereum. Access DeFi with Bitcoin security.

How Ethereum ↔ VIA bridge works

How Bitcoin ↔ VIA bridge works

01
Bridge stablecoins

Choose a stablecoin (e.g.,USDC) to bridge. By bridging, you deposit into VIA vault on Ethereum. The vault is built on the ERC-4626 standard, making it compatible with the broader DeFi ecosystem.

02
VIA turns your bridged assets into productive capital

Your bridged assets immediately start earning yield through VIA’s vault strategies — fully automated and hands-off.

03
VIA sends you vTokens

Once your deposit is confirmed, you receive vTokens (like vUSDC) on the VIA L2. Your vTokens stay the same amount, but their value increases over time as yield accumulates.

04
Use or redeem anytime

vTokens can be used across VIA’s ecosystem o earn additional yield on top of base yield, with trading, lending, liquidity pools, borrowing, and paying gas fees. Redeem back to Ethereum at any time and receive your stablecoins + all accumulated yield.

01
Bridge BTC

Bridge your BTC using a secure and trust-minimized design

02
Access VIA DeFi

When you bridge to VIA, you will receive 1:1 for the amount of BTC bridged. Once on VIA, your BTC becomes fully usable in DeFi to earn yield, provide liquidity, trade, borrow, use as collateral, and enjoy a gasless experience.

03
Use or redeem anytime

You can redeem your BTC back from VIA to Bitcoin chain at any time, and receive your bridged assets + anything you earned using VIA DeFi. You will receive your BTC on Bitcoin without additional transactions.

EXAMPLE
Deposit
1,000 USDC
Hold
1,000 vUSDC
Later redeem
1,050 USDC
after yield accrues
EXAMPLE

KEY BENEFITS

Bridge once.
Earn continuously.

ETH ↔ VIA bridge does more than bridging the assets. It transforms them into productive capital from the first block they land on VIA.

Using VIA Bridge unlocks a number of features that make your ETH assets more useful and profitable on VIA.
Automatic Yield for Ethereum assets
Your USDC earns 5% APY on AAVE while you use vUSDC on VIA.
Growing Value
vUSDC balance stays constant, but its value increases over time.
Fully Composable
Use vUSDC for trading, liquidity pools, collateral, or gas fess anywhere in VIA.
Reduced gas costs
User enables gasless transactions and the possibility to pay gas with vToken.
Bridging security
We are using LayerZero for cross-chain messaging between Ethereum and VIA
KEY BENEFITS

Bridge once.
Earn constantly using DeFi.

VIA Bridge brings more than just cross-chain transfers for BTC users. It makes your assets work for you from the moment you start using DeFi on VIA.

Using VIA Bridge unlocks a number of features that make your BTC more useful on VIA.
Fully Composable
Use your BTC across VIA for  trading, liquidity pools, collateral, or gas fees, fully composable throughout the VIA ecosystem
Gasless transactions
User enables gasless transactions
Bridging security
The audited VIA<>Bitcoin bridge is fully audited and built using a MuSig2 wallet, which requires all signers to approve any withdrawal. Funds remain secure as long as at least one signer is honest.

Frequently asked questions

What is the VIA Bridge?

VIA Bridge is VIA Network’s native cross-chain bridge between Bitcoin, Ethereum and the VIA L2. It converts deposited assets into yield-bearing vTokens on VIA, while the underlying assets remain in an ERC-4626 vault and DeFi strategies on Ethereum. User can deposit to VIA from Ethereum and Bitcoin (BTC yield coming soon).

Which assets does the VIA Bridge support?

ETH ↔ VIA Bridge focuses on stablecoins, including USDC (others to follow)

How is yield generated on bridged assets?

Once you bridge you assets, you deposit it on VIA, and in return you recieve vTokens. Deposited stablecoins are routed into strategies like Aave on Ethereum through the VIA vault. As those strategies earn yield, the total assets in the vault increase while the total shares remain constant. That raises the exchange rate, so each vToken is redeemable for more underlying – which is how your yield accrues.

What are vTokens?

vToken is an ERC-4626 yield-bearing token native to VIA L2. It represents a user's share of the underlying lending pools on Ethereum, where their bridged assets are deposited. vTokens continuously accrue value as interest is earned on Ethereum, and at any time they can be redeemed for the underlying assets plus yield. On VIA, vTokens are the default currency. They can be used to pay transaction fees, provide liquidity, swap, or serve as collateral in other DeFi applications.

Can I withdraw/redeem at any time?

Yes. vTokens are fully redeemable at any time. A user who holds vTokens on VIA can exit the system by bridging back to Ethereum, where their share of the underlying lending pool is unlocked. Redemption always reflects both the principal and the accumulated yield up to that moment. If a user tries to redeem assets and there's no liquidity, the transaction will revert and fail because the smart contract cannot fulfill the request. To enable redemption, the user must wait for more liquidity to be supplied to the pool or for existing borrowers to repay their loans. They might also need to monitor the pool's utilization rate to see when liquidity becomes available.

What are the main risks?

Bridges are common targets for exploits because they rely on complex smart contracts and cross-chain logic. A single vulnerability can put locked assets at risk. To reduce this risk, we provide thorough smart-contract audits, continuous monitoring, and security alerts to detect issues early and keep your cross-chain activity safer.

Is the VIA Bridge live on mainnet?
