How to check if a route is supported?

To determine if a route is supported (also referred to as whether a token is supported for bridging), use the Chains API to check for an available route between a given token pair.

curl -X GET "https://api.relay.link/chains"

The response will return a list of chains, each containing supported token pairs. To verify if a route is supported, follow these steps:

​
Step 1: Check Token Support Level

Look for the tokenSupport field in the response for a given chain:

  • If tokenSupport is "All", then routes involving this chain as either the origin or destination are supported for tokens where Solver or DEX liquidity is available.
  • If tokenSupport is "Limited", proceed to step 2.

​
Step 2: Check Individual Token Support

If tokenSupport is "Limited", check the erc20Currencies and currency fields in the response. These fields contain token objects with metadata indicating whether a token supports bridging.

​
Step 3: Verify Bridging Support

Locate the supportsBridging field in the token object:

  • If supportsBridging is true, the token is supported for bridging.
  • If supportsBridging is false or if the token pair is not listed in erc20Currencies or currency, then the route is not supported.

                    "depositFee": 0,
                    "surgeEnabled": false
                },
                {

                    "symbol": "USDC",

                    "decimals": 6,
                    "supportsBridging": true,
                    "supportsPermit": true,
                    "withdrawalFee": 0,
                    "depositFee": 0,
                    "surgeEnabled": false
                }
            ]
        }
  ]
}

Since the tokenSupport field is "All", routes involving this chain are supported for tokens where Solver or DEX liquidity is available.

​
Example: Limited Token Support

{
  "chains": [
        {
            "id": 7777777,
            "name": "zora",
            "displayName": "Zora",
            "tokenSupport": "Limited",
            "currency": {
                "id": "eth",
                "symbol": "ETH",
                "name": "Ether",
                "address": "0x0000000000000000000000000000000000000000",
                "decimals": 18,
                "supportsBridging": true
            },
            "erc20Currencies": [
                {
                    "id": "usdc",
                    "symbol": "USDzC",
                    "name": "USD Coin (Bridged from Ethereum)",
                    "address": "0xcccccccc7021b32ebb4e8c08314bd62f7c653ec4",
                    "decimals": 6,
                    "supportsBridging": true,
                    "withdrawalFee": 0,
                    "depositFee": 0,
                    "surgeEnabled": false
                }
            ]
        }
  ]
}

Here, tokenSupport is "Limited", meaning only specific tokens can be bridged. In this case, usdc is listed under erc20Currencies with supportsBridging: true, so routes involving usdc as an origin or destination token on Zora are supported.

API Reference

For the most up-to-date information on supported tokens and routes, always refer to the Chains API endpoint, as token support can change over time.
