Bitcoin's next chapter. Yield by Default.

ABOUT VIA network

VIA Network is a sovereign zkEVM rollup that anchors security to Bitcoin and brings native yield to every asset.

Bitcoin users can bridge BTC directly from Bitcoin to access DeFi, while Ethereum users can bridge assets to VIA — both become vTokens that accrue yield automatically. Via serves as the central meeting point where Bitcoin and Ethereum users converge to unlock the full potential of DeFi.

With Bitcoin's massive liquidity, BTC users have unparalleled access to yield-generating opportunities. Yield is built into VIA's core architecture, secured by Bitcoin and finalized through a decentralized zero-knowledge verifier network.

Via Network Features

Bitcoin Security, Modern Scalability

VIA combines Bitcoin’s proven trust layer with zk-rollup scalability, delivering a secure and efficient environment for decentralized applications.

EVM Compatibility with BTC as Gas

Deploy Ethereum-based smart contracts directly on Bitcoin. VIA enables full EVM compatibility while keeping BTC as the native gas asset.

Built for Builders, Powered by Bitcoin

Developers can launch DeFi, NFTs, and next-gen protocols with the reliability of Bitcoin and the speed of modern rollup technology.

The Connection Between Ecosystems

VIA unites Bitcoin’s stability with Ethereum’s innovation, delivering true interoperability for the next wave of blockchain growth.

VTOKENS

The Core Asset of the Via Economy

vTokens (Via Tokens) aren't just passive receipts, they're fully composable assets that power the entire Via ecosystem.

Native Utility Across the Chain

vTokens are natively supported within Via, enabling users to:
Pay Transaction Fees
Pay transaction fees directly using vTokens — no separate gas token required.
Trade on DEXes
Trade on DEXes (e.g., vUSDC/vUSDT pairs and other vToken markets).
Provide Liquidity in AMMs
Provide liquidity in AMMs and earn additional rewards on top of base yield.
Use as Collateral
Use as collateral for borrowing and lending across all DeFi applications on Via.
vTokens form the backbone of Via's productive Layer 2, assets that earn, move, and build value across the entire Bitcoin-secured DeFi economy. Transfer, swap, and compose freely across all DeFi applications on Via.
Yield on VIA

This example shows how users can generate multiple layers of yield within the VIA ecosystem. By bridging assets from Ethereum, users immediately begin earning passive income as their tokens convert into yield-bearing vTokens.

These vTokens can then be deployed across VIA's DeFi protocols — for trading, lending, or providing liquidity — allowing users to stack additional rewards on top of the base yield.

Frequently asked questions

What is vToken?

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.

How does a user harvest their yield on VIA and Ethereum?

Yield accrues automatically within the redemption value of vTokens. Users do not need to manually "claim" rewards. On VIA, the vToken balance in a wallet remains the same, but its redemption rate into the underlying asset increases over time. When a user redeems vTokens (either on VIA or back on Ethereum), they receive the underlying principal plus accrued yield. And this yield can be used directly on VIA as this token is an ERC4626.

What can users do with vTokens?

vTokens are fully composable assets within the VIA ecosystem: Pay transaction fees on VIA. Provide liquidity in VIA's native DEX pools. Trade and swap like any ERC-20. Post as collateral for borrowing or derivatives. Simply hold as a yield-bearing store of value. All of these uses are possible while vTokens continue to accrue yield from the Ethereum lending pools.

Can a user redeem their tokens at any time?

Yes. vTokens are fully redeemable at any time. <br>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.

How often is the vToken exchange rate updated?

The redemption rate of vTokens is updated on a regular schedule to reflect interest accrued in Ethereum lending pools. By default, this happens hourly, but the update frequency can be reduced to every five minutes or less, depending on network activity and liquidity conditions. This ensures that yield accrual remains responsive and accurate without sacrificing efficiency.
