Arguments
| Property | Description | Required |
|---|---|---|
| parameters | Quote parameters defined below | ✅ |
| includeDefaultParameters | Setting this to true will include default parameters, which include user and recipient. These parameters are based on the wallet and fallback to the dead address if the wallet is missing. | ❌ |
| headers | Custom headers to pass along with the quote request, such as x-api-key for authentication. | ❌ |
Warning: Never pass
x-api-key in headers from client-side code. Only use the headers parameter with API keys when calling getQuote entirely on the server.Quote Parameters
| Property | Description | Required |
|---|---|---|
| chainId | The chain id to deposit funds on | ✅ |
| toChainId | The chain id to execute the txs on | ✅ |
| currency | Address for a supported native currency or valid erc20 | ✅ |
| toCurrency | Address for a supported native currency or valid erc20 | ✅ |
| user | The user or sender of the bridge. This must be defined if not using includeDefaultParameters. | ✅ (❌ if includeDefaultParameters is true) |
| recipient | The recipient of the bridge. This must be defined if not using includeDefaultParameters. | ✅ (❌ if includeDefaultParameters is true) |
| tradeType | Either EXACT_INPUT for quoting via an input amount, or EXPECTED_OUTPUT/EXACT_OUTPUT for quoting via an output amount. | ✅ |
| amount | Amount in wei, in the supplied currency | ❌ |
| wallet | A valid WalletClient from viem or an adapted wallet generated from an adapter that meets this interface. | ❌ |
| txs | An array of either transaction objects (made up of a to, data and value properties) or viem request objects returned from viem’s simulateContract function. | ❌ |
| options | Additional options that map directly to the quote API. | ❌ |
| disableCapabilitiesCheck | Skip wallet.getCapabilities calls used for EIP-5792 atomic-batch detection and smart-wallet detection. Set this for wallets with a broken getCapabilities implementation that hangs or never resolves. When true, execution falls back to sequential transactions. | ❌ |
Native Bridge Example
import { getClient } from "@relayprotocol/relay-sdk";
import { useWalletClient } from "wagmi";
const { data: wallet } = useWalletClient();
const quote = await getClient()?.actions.getQuote({
chainId: 1,
toChainId: 10,
currency: "0x0000000000000000000000000000000000000000",
toCurrency: "0x0000000000000000000000000000000000000000",
amount: "10000000000000000", // 0.01 ETH
wallet,
user: "WALLET_ADDRESS", //Replace with your wallet address
recipient: "RECIPIENT_ADDRESS", //Replace with the recipient address
});
Cross-Chain Swap Example
// Cross-Chain Swap from USDC on Ethereum to DAI on Optimism
const quote = await getClient()?.actions.getQuote({
chainId: 1,
toChainId: 10,
currency: "0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48", // USDC on Ethereum
toCurrency: "0xda10009cbd5d07dd0cecc66161fc93d7c9000da1", // DAI on Optimism
amount: "100000", // 100 USDC
wallet,
user: "WALLET_ADDRESS", //Replace with your wallet address
recipient: "RECIPIENT_ADDRESS", //Replace with the recipient address
});
Wrap/Unwrap Example
// Unwrap ETH
const quote = await getClient()?.actions.getQuote({
chainId: 1,
toChainId: 1,
currency: "0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2", // WETH
toCurrency: "0x0000000000000000000000000000000000000000",
amount: "10000000000000000", // 0.01 ETH
wallet,
user: "WALLET_ADDRESS", //Replace with your wallet address
recipient: "RECIPIENT_ADDRESS", //Replace with the recipient address
});
Send Example
// Send ERC20 / Native Currency to another address on the same chain
// Note: The recipient address must be specified for send transactions and be different from the wallet address
const quote = await getClient()?.actions.getQuote({
chainId: 1,
toChainId: 1,
currency: "0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48", // USDC
toCurrency: "0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48",
amount: "100000", // 100 USDC
wallet,
user: "WALLET_ADDRESS", //Replace with your wallet address
recipient: "0x0000c3caa36e2d9a8cd5269c976ede05018f0000",
});
Server-Side Example with API key
// Server-side only - pass API key via headers
const quote = await getClient()?.actions.getQuote(
{
chainId: 1,
toChainId: 10,
currency: "0x0000000000000000000000000000000000000000",
toCurrency: "0x0000000000000000000000000000000000000000",
amount: "10000000000000000", // 0.01 ETH
user: "WALLET_ADDRESS",
recipient: "RECIPIENT_ADDRESS",
