Execute Cross-Chain Swaps With Our Meta Aggregator API
Execute cross-chain swaps across 30+ chains through one API. Production infrastructure for wallets, protocols, AI agents. Intent to settlement in 2026.

As Web3 UX improves, you are increasingly expected to support seamless asset movement across chains. Your users no longer think in terms of networks, bridges, or wrapped assets.
Users think in terms of intent: swap this asset into that asset, now. Making that happen is still hard, with execution fragmented across chains, DEXs, aggregators, bridges, and asset standards.
The 1delta Meta Aggregator API abstracts that entirely.
This blog explains what the API does, what it supports today, and the real problems it solves for builders.
What the 1delta Meta Aggregator API Does
The 1delta Meta Aggregator API is an execution layer that lets you swap any asset into any other asset across supported chains through a single integration.
From your application’s perspective, the interaction is simple. You specify the input asset, the output asset, and the amount. Everything else is handled by the API.
Under the hood, the API orchestrates:
Liquidity sourcing across DEXs and aggregators
Optimal routing based on price and execution constraints
Native, wrapped, and bridged asset handling
Cross chain execution and settlement when required
This abstraction allows you to express user intent without exposing execution complexity to your product or your users.
The API is designed to be embedded directly inside any dapp, website, mobile app, or backend service.
The Stack and What Is Supported Today
The 1delta Meta Aggregator API is built as a composable execution stack that sits on top of existing liquidity and routing infrastructure.
It does not replace DEXs or aggregators, but coordinate them more efficiently.
Today, the API supports execution across a broad set of chains, liquidity sources, and routing layers, while exposing a single, consistent interface to developers.
Chain support
The API currently supports execution across the following networks:
Ethereum, Arbitrum One, Base, Optimism, Polygon, BNB Chain, Avalanche, Gnosis, Linea, Blast, Mantle, Scroll, Taiko, Core, Fuel, Hemi, Plasma, Sonic, Monad, Berachain, Sei, Moonbeam, Manta Pacific, XDC, Morph, Unichain, Soneium, Cronos, Katana, and HyperEVM.
Support includes native asset handling and chain specific execution nuances where applicable.
DEX coverage
On each supported chain, the API sources liquidity across all major DEXs, including:
Constant product AMMs
Stable swap pools
Concentrated liquidity markets
Chain native DEXs
Execution is not tied to a single venue. The API dynamically selects liquidity based on the best execution path for a given swap.
Aggregator coverage
Where aggregators provide better pricing or deeper liquidity, the API routes through them. Where direct DEX execution is superior, it bypasses them.
In practice, this means:
Aggregators are treated as liquidity sources
No single point of failure in routing
Consistent execution behavior across chains
This layered approach allows the API to remain flexible as new chains, DEXs, and aggregators are added, without requiring changes to your integration.
Top Crypto Use Cases In 2026
By 2026, most crypto products will no longer be built around chains or assets. Theywill be built around flows. The Meta Aggregator API shows up wherever those flows break today.
Below are the patterns where teams are already integrating this kind of execution layer.
1. Intent-driven wallets and smart accounts
Wallets are moving beyond “send” and “swap” into intent execution.
Instead of asking the user to pick a chain, token, and route, the wallet captures intent and delegates execution.
Common flows:
Swap any held asset into a target asset required by a dapp
Move value across chains as part of a single user action
Execute actions from smart accounts without exposing intermediate steps
The API becomes the execution backend that resolves intent into actual swaps and transfers across chains.
2. Protocols that accept capital
Newer DeFi protocols are no longer designed around a single canonical deposit asset.
What they want:
Accept capital from anywhere
Normalize it internally
Issue positions against a single accounting asset
Using the API, protocol frontends can:
Accept deposits in arbitrary assets and chains
Convert them into the protocol’s required collateral or position token
Avoid forcing users to bridge or swap before interacting
This shifts complexity out of the user flow and into the execution layer.
3. AI agents with real execution authority
By 2026, AI agents will be execution actors. They rebalance portfolios, move treasury funds, manage strategies, and react to market conditions. What they cannot do reliably is manage chain-specific logic.
The API gives agents:
A single execution primitive for moving value
Deterministic behavior across chains and assets
A clean separation between decision logic and execution
Agents express intent. The API handles execution.
4. Cross-chain strategy engines and vaults
Strategy products increasingly span multiple chains by default.
Common requirements:
Reallocate capital when yields shift across chains
Consolidate rewards into a base asset
Exit or rotate positions without manual routing logic
Instead of building custom execution paths per chain, strategy engines rely on the API to:
Handle asset conversion
Select execution venues
Settle positions across chains
This reduces strategy complexity and operational risk.
5. Embedded payments in non-financial apps
Games, social apps, and consumer products are embedding onchain payments without wanting to become wallets.
They care about:
Accepting value
Settling in a specific asset
Avoiding user confusion
With the API:
Users pay with whatever they already hold
The app receives settlement in its preferred asset
Chains and swaps stay invisible
This makes onchain payments usable outside DeFi.
6. Treasury, portfolio, and risk tooling
Treasury and portfolio tools increasingly operate across multiple chains by default.
Typical actions:
Consolidate balances
Rotate exposure
Normalize assets for reporting or deployment
The API allows these tools to execute asset transitions without maintaining chain-specific logic or routing infrastructure.
Integration Model and Next Steps
The Meta Aggregator API is designed to be integrated as a backend execution primitive. From an integration standpoint, the model is intentionally simple:
A single API surface for cross asset and cross chain execution
No need to manage DEX integrations, aggregators, or bridges
No chain specific logic in your frontend or agent layer
Execution driven by intent, not routing configuration
You define what needs to happen. The API handles how it happens.
This makes the API suitable for:
Frontends that need embedded swaps
Backend services executing on behalf of users
Strategy engines and automation systems
AI agents with execution authority
If you are building an application that needs reliable cross chain execution without infrastructure overhead, the Meta Aggregator API is designed to slot directly into your stack.
