Bridge Tokens Across Chains

Auto moves tokens from one blockchain to another in a single command. You specify the token, the source chain, and the destination chain — Auto handles route selection, quoting, execution, and transfer tracking. Bridging with Auto eliminates the need to interact with bridge protocols directly.

What Is Bridging?

Bridging is the process of transferring a token from one blockchain to another. For example, moving USDC from Base to Arbitrum, or moving funds from an EVM chain to Solana. Each blockchain maintains separate balances, so bridging is required to relocate assets between networks.

Auto manages the entire bridge workflow: route discovery, quote verification, transaction submission, and post-transfer status tracking.

Example Prompts for Bridging Tokens

"Bridge $3 USDC from Base to Polygon"

"Bridge $2 USDC from Base to Arbitrum"

"Bridge $2 USDC from Base to Optimism"

"Bridge $2 USDC from Base to Solana"

"Bridge $3 USDC from Base to Solana, then check when it arrives"

"Bridge my USDC from Arbitrum back to Base"

"Check the status of my last bridge"

Which Chains Does Auto Support for Bridging?

Auto supports bridging between all major EVM chains and Solana:

Bridge Path	Supported Chains
EVM to EVM	Base, Ethereum, Arbitrum, Optimism, Polygon
EVM to Solana	Any supported EVM chain → Solana
Solana to EVM	Solana → Any supported EVM chain

Common Bridge Routes and Use Cases

Route	Use Case
Base → Polygon	Access lower-cost transactions or Polygon-native dApps
Base → Arbitrum	Trade or use DeFi protocols on Arbitrum
Base → Solana	Access Solana ecosystem tokens and protocols
Solana → Base	Move funds back to an EVM chain for EVM-native activity

What Does Auto Handle During a Bridge?

Auto abstracts all bridge complexity. You do not need to select a bridge provider, understand token wrapping, or configure routing parameters.

When you request a bridge, Auto:

1. Verifies your balance — confirms you hold enough of the token on the source chain

2. Checks route availability — validates that a supported path exists between the two chains

3. Quotes the transfer — shows the expected amount arriving on the destination chain

4. Estimates timing — provides an approximate transfer duration when available

5. Executes the transaction — submits the bridge after your confirmation

You can express your intent simply:

"Move $5 to Solana"

Auto determines the optimal route based on your wallet holdings.

How to Track Bridge Transfer Status

Bridge transfers are not always instant. Auto tracks your transfer status and reports progress when you ask.

Status	What It Means
Pending	The transfer has been submitted and is in progress
Complete	The funds have arrived on the destination chain
Needs attention	Something unexpected occurred — Auto helps you investigate

Example Prompts for Tracking Bridges

"Check my bridge status"

"Did my transfer to Solana arrive yet?"

"Track my last bridge from Base to Arbitrum"

If a bridge provider supports recovery or follow-up tracking, Auto uses that data to provide accurate status updates.

What If My Bridge Is Slow?

Ask Auto to check the status directly instead of relying on wallet balances alone. Bridge times vary by route and network congestion. Auto queries the bridge provider for real-time status rather than inferring from on-chain balance changes.

Tips for Bridging Tokens

• Specify the destination chain clearly. If Auto cannot determine the target, it asks a follow-up question.

• Tokens may arrive in a wrapped or chain-native version on the destination. Auto explains the result in plain terms.

• You can bridge first and swap later, or describe the end result you want and let Auto find the combined route.

• After sending a bridge, ask Auto to check the transfer status for real-time updates.

• Bridge and swap operations can be chained. For example: "Bridge USDC to Solana and swap to SOL."
