Who We Are

Vault Bridge
Protocol

Built for the next generation of blockchains. Vault Bridge converts idle bridged capital into real, recurring revenue — without token inflation, without conditions, without new infrastructure.

Our Mission

A Protocol Built for
Sustainable Growth

Blockchains have a revenue problem. Most chains fund operations through token emissions — a model that dilutes holders and creates dependency on speculation. Vault Bridge was built to change that.
Real Revenue, Not Emissions
Token incentives run out. TVL-backed yield does not. Every asset bridged to your chain through Vault Bridge generates income tied to actual usage — not printing schedules.
Designed for Agglayer
Vault Bridge integrates natively with Agglayer chains. Any chain — new or existing, EVM or non-EVM — can plug in without touching its canonical bridge or migrating users.
No New Infrastructure
The Vault Bridge team built the protocol to be drop-in. Deployment requires no changes to existing smart contracts and no new validator sets — just integration with the Vault Bridge vault layer.
Technology

How the Vault Bridge Stack Works

Three moving parts. Each one battle-tested. Together they form the only yield routing system purpose-built for chain-level treasuries.
Layer 1 — Bridging
Asset Routing via Agglayer Bridge

Users bridge ETH, USDC, USDT, USDS, or WBTC. They receive 1:1 representations on the target chain. The underlying assets do not sit idle — they enter the Vault Bridge vault pipeline immediately.

Layer 2 — Yield
Morpho Vaults on Ethereum

Bridged capital is deployed to Morpho vaults on Ethereum mainnet. These vaults follow the ERC-4626 standard — immutable, audited, and curated by Gauntlet and Steakhouse Financial. Risk parameters are set per chain profile.

Layer 3 — Distribution
Revenue Streamed On-Chain

Yield is continuously streamed back to the chain via Vault Bridge contracts. The chain configures a recipient address. From there the team decides: fund gas sponsorship, dev grants, or operational expenses.

Layer 4 — Governance
Chain-Level Control

Each integrated chain retains full authority over its yield destination. Opt-in or opt-out mechanisms can be surfaced to users. The Vault Bridge protocol does not impose a fixed distribution model.

Our Approach

Built on Proven Principles

The Vault Bridge platform was not designed to maximize complexity. It was designed to maximize reliability. Four principles guide every decision.
1
Immutability over upgradeability

Smart contracts at the core of Vault Bridge do not have admin keys. Morpho vaults are immutable by design. This is a deliberate choice — fewer upgrade vectors mean a smaller attack surface for chain treasuries managing millions in TVL.

2
Expert risk curation, not DIY

Gauntlet and Steakhouse Financial manage strategy weights. These teams have years of DeFi risk experience across protocols like Compound and Aave. A chain team should not need to become a DeFi quant to access safe yield.

3
Composability with existing systems

Vault Bridge does not replace existing bridge infrastructure. Chains on Base, on Polygon CDK, or running custom rollup stacks can all integrate. The protocol is additive — it generates yield on top of whatever bridge flow the chain already has.

4
Transparency at every layer

Vault positions, yield rates, and distribution flows are on-chain and verifiable. The Vault Bridge protocol does not obscure how capital moves. Every dollar of TVL has a traceable path from the bridge to the vault to the chain treasury.

Ecosystem

Who Builds with Vault Bridge

Vault Bridge is an Agglayer-native product. It is available to any chain that connects to the Agglayer network — at no cost. The protocol is free for connected chains. That is not a promotional offer; it is the model.
New Chains
Teams launching on Agglayer can activate Vault Bridge from day one. Revenue starts the moment users bridge in — no minimum TVL threshold, no waiting period.
Existing Chains
Chains already live with existing state can integrate without migrating users. Vault Bridge earns yield on new bridged assets only — it does not require a full bridge replacement.
Non-EVM Networks
Through partner bridge integrations, ecosystems outside the EVM — including SVM (Solana), Cosmos, and Move-based chains like Aptos and Sui — can access Vault Bridge yield infrastructure.
Team & Partners

The People and Protocols
Behind Vault Bridge

Vault Bridge is built by the Agglayer team in collaboration with leading DeFi infrastructure providers. The protocol would not exist without each of these partnerships.
Agglayer

The cross-chain settlement layer that connects liquidity and users across blockchains. Vault Bridge is the revenue primitive built natively into the Agglayer product suite. Chains on Agglayer get access automatically.

Morpho

Morpho provides the immutable ERC-4626 lending vaults where bridged capital is deployed. Morpho's architecture is non-custodial and permissionless — two properties that matter significantly when managing chain treasury funds.

Gauntlet

Gauntlet is a quantitative risk firm that manages vault strategy weights within Vault Bridge. Their models are calibrated for on-chain lending markets and have been applied across multiple major DeFi protocols since 2019.

Steakhouse Financial

Steakhouse Financial provides additional risk curation and strategy oversight. Their involvement adds a second layer of review to vault allocations, reducing single-point-of-failure risk in yield strategy management.
