Turn your chain's bridged TVL into a real, recurring revenue stream — without printing tokens or changing your existing bridge.
Read the docs Common questionsMost chains fund growth by inflating supply. Vault Bridge's protocol takes a different view: idle bridged capital is a resource, not a liability. Here is what that means in practice.
Every dollar users bridge in earns yield. The more the protocol holds, the more your treasury receives — no additional work on your part.
Incentive programs end the moment funding does. Vault Bridge replaces that with income tied to real on-chain activity.
Underlying yield comes from ERC-4626-compliant Morpho vaults. Risk weights are set by Gauntlet and Steakhouse Financial — two of the most cited risk teams in DeFi.
The Vault Bridge platform bolts on. Your canonical bridge keeps running exactly as before. Integration is configuration, not a rewrite.
Four discrete steps. No new trust assumptions. Funds never leave the Ethereum mainnet vault layer until a user withdraws.
ETH, USDC, USDT, USDS, or WBTC lands on your chain as a 1:1 synthetic. The canonical amount now sits in the Vault Bridge escrow on Ethereum.
Escrow funds are deposited into curated Morpho vaults. Strategy weights are updated by Gauntlet based on your chain's risk profile. Think of it as a managed fund operating entirely on-chain.
Vaults earn lending fees, not speculation. The protocol does not take directional bets. Rates fluctuate with market demand for each asset — typically between 3 % and 9 % APY depending on asset and epoch.
Vault Bridge contracts send accrued yield to whatever address you configure. Use it for gas sponsorship, dev grants, liquidity incentives — the choice belongs to your governance.
Principal is always redeemable 1:1. Only yield is redirected. This differs from Compound-style lending where the depositor keeps the interest themselves.
Every position is a tokenized vault share. Composable with any protocol that reads the ERC-4626 standard.
ETH, USDC, USDT, USDS, and WBTC at launch. Additional assets added via governance vote. Five assets cover the majority of bridged value on Agglayer today.
One parameter change sets where revenue goes. Point it at a multisig, a DAO treasury, a gas subsidy pool, or a smart contract — your call.
Native for EVM chains. Through bridge-provider partnerships, the team behind Vault Bridge extends support to Solana SVM, Cosmos IBC chains, and Move-based networks like Aptos and Sui.
Gauntlet runs quantitative risk models on vault allocations. Steakhouse Financial provides independent review. Neither party can unilaterally move user funds.
Operators can expose a flag that lets individual users withdraw their principal from yield routing at any time without leaving the chain.
Chains connected to Agglayer pay no protocol fee. Vault Bridge earns nothing from the spread. Revenue goes entirely to chain operators and, implicitly, to their communities.

Answers to the most common questions about the Vault Bridge platform. A longer list lives at the FAQ page. Chain builders can also visit the company page for background on the team.
New chains launching on Agglayer, existing chains looking to monetize new TVL, or builders who need a secure yield building-block. If your chain holds bridged assets that sit idle, Vault Bridge converts that idle capital into a revenue line.
Vault Bridge relies on Morpho's immutable ERC-4626 vaults — contracts that cannot be upgraded by any single party. Risk curation is handled by Gauntlet and Steakhouse Financial. All vault contracts are publicly audited and the code is open source.
At launch: ETH, USDC, USDT, USDS, and WBTC. Users receive a 1:1 representation on the destination chain. New assets go through a governance process before activation.
Bridged assets sit in Morpho vaults on Ethereum mainnet, earning yield through institutional lending strategies curated by Gauntlet. That yield streams back to the connected chain. No token is minted. No supply is diluted.
Yes. Vault Bridge does not replace your canonical bridge. It works alongside existing infrastructure. No code changes are required on the bridge side — only the Vault Bridge contracts need to be configured.
Morpho provides the underlying vault layer. Vault Bridge routes bridged capital into Morpho's ERC-4626-compliant vaults, then pipes yield back to your chain via dedicated contracts. The relationship is modular: Morpho handles custody, Vault Bridge handles routing logic.
Incentive programs dilute token supply and stop the moment funding ends. Vault Bridge revenue scales directly with TVL and never touches your token. A chain with $50M in bridged USDC earning 5% APY generates $2.5M per year — every year that TVL stays.
Connect your chain to Agglayer, then configure the Vault Bridge contracts to point yield at your chosen treasury address. Full integration docs are at docs.agglayer.dev. Most teams complete setup in under a week.
You set the destination address. Common uses: sponsoring user gas on a gaming chain, funding dev grants, bootstrapping liquidity programs, or covering sequencer operating costs. One parameter, complete flexibility.
Vault Bridge is available to all Agglayer-connected chains. Non-EVM ecosystems — including Solana, Cosmos IBC chains, and Move-based networks — are accessible via bridge-provider partnerships that the team behind Vault Bridge maintains.
Base is an EVM-compatible chain. Any EVM chain that connects to Agglayer can use Vault Bridge. Whether Base connects is a Base governance decision, not a technical limitation of the protocol.
Compound lets individual users supply assets and keep the interest themselves. Vault Bridge aggregates all bridged TVL into curated Morpho vaults and sends the earnings to the chain operator — not to individual depositors. It is a chain-level revenue primitive, not a retail lending product.
Chain operators can configure Vault Bridge to expose an opt-out flag for users. Principal is always redeemable 1:1 regardless of configuration. Operators decide how much choice to surface to end users.
Vault Bridge earns yield only on assets bridged after integration is live. Pre-existing bridge deposits are not touched, and users who bridged before activation are not automatically enrolled.
