Multi-chain vault deployment: why 18+ networks matter

Introduction

Ethereum still commands roughly 68% of all DeFi total value locked (TVL), but the other 32%, over $40 billion, is distributed across Layer 2s (L2s), alt-L1s, and emerging chains. Base alone holds $4.1 billion. Arbitrum sits at $2.8 billion. Avalanche, Sonic, and a growing list of newer networks each carry hundreds of millions to billions in capital.

At Lagoon, we have deployed over 800 vaults across 18+ EVM chains to date. That cross-chain visibility shows us something consistent: capital follows opportunity, and opportunity is not chain-specific. A stablecoin lending strategy that works on Ethereum works just as well on Arbitrum, often with lower gas costs and different LP demographics. The question is not whether to go multi-chain; it's how to do it without fragmenting your operational overhead.

Where DeFi capital actually lives

The common assumption that "everything is on Ethereum" stopped being accurate in 2024. By April 2026, the distribution looks like this:

Base grew from $3.1 billion in January to a peak above $5.6 billion in October 2025, capturing roughly 46% of all L2 DeFi TVL. Arbitrum and Base together represent over 75% of the L2 category. But the long tail matters too: Sonic, Mantle, Linea, and HyperEVM are each building ecosystems with native DeFi protocols and unique LP bases.

For vault curators, this distribution creates a straightforward calculus. Deploying only on Ethereum means competing for the most crowded liquidity. Deploying on L2s means access to less competitive yield sources and LPs who are native to those ecosystems.

The practical challenge has always been friction: writing chain-specific deployment scripts, managing different RPC endpoints, verifying contracts on each block explorer, and maintaining operational tooling across networks. This is the problem a permissionless Vault Factory solves.

How the Vault Factory works across chains

Lagoon's Vault Factory is a single smart contract that produces identical ERC-7540 vaults on every supported chain. The process is the same whether you're deploying on Ethereum, Arbitrum, or Monad: select a network, pick an underlying asset, assign governance roles, set fees, and deploy. The full walkthrough is covered in How to deploy a permissionless vault on Lagoon in minutes.

What stays constant across every chain:

• ERC-7540 standard: async deposits, forward pricing (exchange rate set at settlement, not request time), request-then-claim settlement
• 4 governance roles: vault admin, curator, valuation provider, whitelist manager (each with independent permissions)
• Fee logic: management fees and performance fees with high-water mark tracking, enforced by the contract
• Security: 8+ audits from NethermindSec and Trail of Bits, time-locked parameter changes, silo architecture for pending deposits

No custom contracts. No chain-specific modifications. No re-auditing. A curator who knows how to operate a vault on Ethereum already knows how to operate one on Base or Sonic.

Supported networks

As of April 2026, the Vault Factory is live on: Ethereum, Arbitrum, Base, Optimism, Polygon, Avalanche, Sonic, Linea, Mantle, HyperEVM, Monad, Sei, Unichain, Worldchain, Katana, Plasma, and TAC. Additional chains can be added on request, since deploying the Factory contract to a new EVM chain is a standard operation.

Chain selection: a framework for curators

Not every chain is worth deploying on. The decision depends on four variables: liquidity depth, gas economics, ecosystem access, and LP demographics.

Liquidity depth determines whether your vault can source yield efficiently. Ethereum has the deepest DeFi liquidity ($52.9 billion in TVL), which means more lending markets, more DEX volume, and more composability with other protocols. For strategies that need to move large positions without slippage, Ethereum is still the default.

Gas economics matter most for strategies with frequent rebalancing. A delta-neutral strategy that rebalances daily on Ethereum might cost $50 to $200 per settlement cycle in gas. The same operations on Arbitrum or Base cost cents. For high-frequency strategies, L2s are not optional; they are the only economically viable execution environment.

Ecosystem access varies by chain. Base has a direct pipeline to Coinbase's user base. Sonic (formerly Fantom) has rebuilt its DeFi stack with native protocols optimized for speed. HyperEVM ties into HyperLiquid's perpetuals infrastructure. Each ecosystem offers yield sources that are unique to that chain.

LP demographics are the most underappreciated factor. Ethereum LPs tend to be larger, more institutional, and slower to move. L2 LPs skew smaller, more active, and more responsive to new vault launches. A curator launching a new strategy might attract initial depositors faster on Base than on Ethereum, then expand to Ethereum once the strategy has a track record.

Cross-chain execution patterns

Once you decide to go multi-chain, there are two distinct architectural patterns. Each involves trade-offs, and the right choice depends on your strategy type and operational setup.

Pattern A: single vault, bridging curator

Deploy one vault (typically on Ethereum or an L2) and use the curator wallet to bridge capital to other chains for execution. Safe wallets with bridging modules make this possible without leaving the multisig security model.

This works well for strategies that aggregate yield across chains but want a single LP entry point. The trade-off is bridge risk on every capital movement and more complex net asset value (NAV) computation, since the valuation provider needs to track positions across multiple networks.

Pattern B: one vault per chain

Deploy separate vaults on each chain using the Vault Factory. Each vault has its own deposits, its own share token, and executes strategies locally. LPs deposit on their preferred chain.

This pattern has cleaner operational boundaries. NAV is computed per-chain with no cross-chain dependencies. There is zero bridge risk per vault. The trade-off: LPs must choose which chain to deposit on, and the curator manages multiple vault instances.

Which to choose

Most curators we work with start with Pattern B, deploying separate vaults on 2 to 3 chains where they have the strongest strategy thesis. Pattern A makes sense for advanced curators running complex cross-chain strategies (arbitrage between chains, cross-chain lending optimization) where capital mobility is the edge itself.

The Vault Factory makes both patterns practical by removing the deployment friction. Spinning up a vault on a new chain takes minutes, not weeks of custom integration.
