Token Transfer
After having found a suitable connection, all you need to send a transaction to your or your user's wallet is our
/quote endpoint.const getQuote = async (fromChain, toChain, fromToken, toToken, fromAmount, fromAddress) => {
const result = await axios.get('https://li.quest/v1/quote', {
params: {
fromChain,
toChain,
fromToken,
toToken,
fromAmount,
fromAddress,
}
});
return result.data;
}
const fromChain = 'DAI';
const fromToken = 'USDC';
const toChain = 'POL';
const toToken = 'USDC';
const fromAmount = '1000000';
const fromAddress = YOUR_WALLET_ADDRESS;
const quote = await getQuote(fromChain, toChain, fromToken, toToken, fromAmount, fromAddress);
If a quote for this transfer can be found, it looks like the following:

The
action contains information about what exactly will happen, the estimate will contain information about the estimated outcome of the transaction.But to send the transaction to your wallet, the
transactionRequest has to be used. It is an ethers.js TransactionRequest object which can directly be passed on to a wallet.
The
/quote endpoints offer several parameters that can be used to fine-tune the result.Parameter | Required | Description | Example |
|---|---|---|---|
fromChain | ✅ | The sending chain. Can be the chain id or chain key | DAI |
toChain | ✅ | The receiving chain. Can be the chain id or chain key | POL |
fromToken | ✅ | The token that should be transferred. Can be the address or the symbol | USDC |
toToken | ✅ | The token that should be transferred to. Can be the address or the symbol | MATIC |
fromAddress | ✅ | The sending wallet address | Your wallet address |
toAddress | ❌ | The receiving wallet address. If none is provided, the fromAddress will be used | Your second wallet address |
fromAmount | ✅ | The amount that should be sent including all decimals (e.g. 1000000 for 1 USDC (6 decimals)) | 1000000 |
order | ❌ | Which kind of route should be preferred | BEST_VALUE, BEST_FEE, or BEST_FEE_GAS |
slippage | ❌ | The maximum allowed slippage for the transaction (0.05 represents 5%) | 0.05 |
integrator | ❌ | A string containing tracking information about the integrator of the API | SirSwapALot |
fee | ❌ | The percent of the integrator's fee that is taken from every transaction. 0.02 represents 2%. The maximum fee amount is 10%. | 0.02 |
referrer | ❌ | A string containing tracking information about the referrer of the integrator | ADevotedCustomer |
allowBridges | ❌ | List of bridges that are allowed for this transaction | multichain,connext |
allowExchanges | ❌ | List of exchanges that are allowed for this transaction | 1inch,paraswap |
denyBridges | ❌ | List of bridges that are not allowed for this transaction | cbridge,optimism |
denyExchanges | ❌ | List of exchanges that are not allowed for this transaction | openocean |
preferBridges | ❌ | List of bridges that should be preferred for this transaction | connext |
preferExchanges | ❌ | List of exchanges that should be preferred for this transaction | 1inch |
The bridges we currently support are:
hop, multichain, cbridge, connext, hyphen, optimism, polygon, arbitrum and avalanche.The currently available exchanges are
1inch, paraswap, openocean, 0x and a lot of dexes.Last modified 17d ago
