With Rhinestone, you can bridge from multiple chains and/or multiple tokens. The API will automatically find the most optimal path, whether it’s a single- or multi-input intent.

​
Request

You can also influence the routing by specifying input tokens and chains via accountAccessList: 
{
  "accountAccessList": {
    "chainIds": ["eip155:10", "eip155:8453"],
    "tokens": ["USDC"]
  }
}
Learn more about choosing the inputs in the “Getting a Quote” guide.

Response

In the case of multi-input bridging, you will get a route whose cost.input lists multiple entries (one per source chain and/or token), and signData.origin[] carries one entry per source chain.

If the user doesn’t have outstanding Permit2 approvals, they will need to approve multiple input tokens. The user will also need to sign each entry in signData.origin[] separately — one signature per input chain.
