Supported Chains and Networks

Auto supports 7 blockchain networks: Ethereum, Base, Arbitrum, Optimism, Polygon, Solana, and HyperEVM. Auto selects the optimal chain automatically for each transaction, so you do not need to specify a chain unless you have a preference.

Chain comparison table

Chain	Gas Token	Swap	Bridge	Lending	Best for
Ethereum	ETH	Yes	Yes	Aave, Morpho	Full DeFi, large trades
Base	ETH	Yes	Yes	Aave	Lowest fees, best starting chain
Arbitrum	ETH	Yes	Yes	Aave	Hyperliquid access, fast execution
Optimism	ETH	Yes	Yes	Aave	Bridge destination, L2 DeFi
Polygon	POL	Yes	Yes	Aave	Polymarket prediction trading
HyperEVM	HYPE	No	No	No	Hyperliquid ecosystem tokens
Solana	SOL	Yes	Yes	No	Jupiter swaps, SPL tokens

What can I do on each chain?

Ethereum, Base, and Arbitrum

These three chains have full feature support in Auto: swaps, bridges, transfers, limit orders via CoW Protocol, Aave lending, Morpho vaults, and on-chain analytics. Base is the recommended starting chain because it has the lowest gas fees. Arbitrum is the gateway to Hyperliquid perpetual trading.

Optimism

Optimism supports swaps, bridges, transfers, and Aave lending. This differs from Base and Arbitrum because Optimism does not support CoW Protocol limit orders or Morpho vaults.

Polygon

Polygon supports swaps, bridges, transfers, and Aave lending. Polygon is also the chain where Polymarket prediction market trading executes, using USDC as the settlement currency.

Note: Polygon uses POL (formerly MATIC) as its gas token, not ETH.

HyperEVM

HyperEVM is the EVM-compatible chain within the Hyperliquid ecosystem. It is used for HyperEVM-specific tokens and on-chain interactions. HyperEVM does not support swaps or bridges through Auto — use Arbitrum to access Hyperliquid perpetual trading instead.

Note: HyperEVM is the only chain where gas is NOT sponsored. You need HYPE tokens to pay for gas on HyperEVM.

Solana

Solana supports Jupiter-powered token swaps, SPL token transfers, and bridging to and from EVM chains. Auto maintains a 0.01 SOL buffer in your wallet to cover Solana transaction fees. This differs from EVM chains because Solana uses a different transaction model and token standard (SPL instead of ERC-20).

How does Auto's chain routing work?

Auto uses automatic chain routing to find the cheapest and fastest execution path. When you submit a request, Auto follows this process:

1. Checks token availability — Identifies which chains hold the tokens you need.

2. Selects the optimal route — Picks the chain with the lowest fees and fastest confirmation time.

3. Handles bridging — Automatically bridges funds between chains if needed to complete the transaction.

You only need to specify a chain when you want to override Auto's selection. Otherwise, Auto handles all routing decisions.

"Swap ETH to USDC" — Auto picks the best chain automatically

"Swap ETH to USDC on Base" — You explicitly choose Base
