Every Composer deposit, whether it targets a vault, staking protocol, or lending market, uses the same API call. Set toToken to the protocol’s token address and LI.FI handles swaps, bridging, and the final deposit. Each recipe below is end-to-end: request a quote, approve tokens, sign the transaction, and confirm the deposit.
All examples use GET /quote. The same toToken addresses work with POST /advanced/routes and the LI.FI SDK. See API Integration or SDK Integration for full integration guides.

​
Same-Chain: USDC → Morpho Vault (Base)

Deposit 1 USDC into a Spark-curated Morpho USDC vault on Base. 
curl -X GET 'https://li.quest/v1/quote?fromChain=8453&toChain=8453&fromToken=0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913&toToken=0x7BfA7C4f149E7415b73bdeDfe609237e29CBF34A&fromAddress=0xYOUR_WALLET_ADDRESS&toAddress=0xYOUR_WALLET_ADDRESS&fromAmount=1000000'
To target a different protocol, swap the toToken for any address listed in the Supported Protocols reference. Everything else stays the same.

​

​
Cross-Chain: ETH (Ethereum) → Morpho Vault (Base)

Deposit ETH from Ethereum into the Morpho vault on Base. LI.FI handles the bridge, intermediate swaps, and deposit. 
curl -X GET 'https://li.quest/v1/quote?fromChain=1&toChain=8453&fromToken=0x0000000000000000000000000000000000000000&toToken=0x7BfA7C4f149E7415b73bdeDfe609237e29CBF34A&fromAddress=0xYOUR_WALLET_ADDRESS&toAddress=0xYOUR_WALLET_ADDRESS&fromAmount=100000000000000000'
Cross-chain transfers require status polling via GET /status. See Cross-Chain Composer Patterns for the full execution flow and partial failure handling.

​
Cross-Chain: USDC (Ethereum) → Morpho Vault (Base)

Bridge USDC from Ethereum and deposit into the Spark-curated Morpho vault on Base. LI.FI handles the bridge and final deposit in one flow. 
curl -X GET 'https://li.quest/v1/quote?fromChain=1&toChain=8453&fromToken=0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48&toToken=0x7BfA7C4f149E7415b73bdeDfe609237e29CBF34A&fromAddress=0xYOUR_WALLET_ADDRESS&toAddress=0xYOUR_WALLET_ADDRESS&fromAmount=1000000000'

​
Felix Vanilla Vaults

Felix Vanilla vaults are supported for deposit and withdraw.

​
Same-Chain: Deposit into Felix Vanilla Vault

curl -X GET 'https://li.quest/v1/quote?fromChain=CHAIN_ID&toChain=CHAIN_ID&fromToken=SOURCE_TOKEN_ADDRESS&toToken=FELIX_VAULT_TOKEN_ADDRESS&fromAddress=0xYOUR_WALLET_ADDRESS&toAddress=0xYOUR_WALLET_ADDRESS&fromAmount=AMOUNT_IN_SMALLEST_UNIT'

​
Neverland Vaults

Neverland vaults are supported for deposit and withdraw.

​
Same-Chain: Deposit into Neverland Vault

curl -X GET 'https://li.quest/v1/quote?fromChain=CHAIN_ID&toChain=CHAIN_ID&fromToken=SOURCE_TOKEN_ADDRESS&toToken=NEVERLAND_VAULT_TOKEN_ADDRESS&fromAddress=0xYOUR_WALLET_ADDRESS&toAddress=0xYOUR_WALLET_ADDRESS&fromAmount=AMOUNT_IN_SMALLEST_UNIT'

​
Depositing on Behalf of Another Address

Some protocols (such as Aave with onBehalfOf) support depositing on behalf of a different wallet. To use this pattern, set toAddress to the recipient’s address:
TypeScript
const { data: quote } = await axios.get(`${API_URL}/quote`, {
  params: {
    fromChain: 8453,
    toChain: 8453,
    fromToken: '0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913',
    toToken: '0x7BfA7C4f149E7415b73bdeDfe609237e29CBF34A',
    fromAddress: '0xSENDER_ADDRESS',
    toAddress: '0xRECIPIENT_ADDRESS',    // Vault tokens go to this address
    fromAmount: '1000000',
    slippage: 0.005,
  },
});
Not all protocols support deposit-on-behalf. If the target protocol does not support it, the API will return an error or ignore the toAddress distinction. Test with your target protocol before relying on this pattern.

​
Pendle Yield Tokens

Pendle enables yield tokenisation. Composer supports deposit and withdraw.

​
Same-Chain: Deposit into Pendle

curl -X GET 'https://li.quest/v1/quote?fromChain=CHAIN_ID&toChain=CHAIN_ID&fromToken=SOURCE_TOKEN_ADDRESS&toToken=PENDLE_TOKEN_ADDRESS&fromAddress=0xYOUR_WALLET_ADDRESS&toAddress=0xYOUR_WALLET_ADDRESS&fromAmount=AMOUNT_IN_SMALLEST_UNIT'

​
Deposit-Only Protocols

The following protocols support deposit only (no withdraw via Composer): For these protocols, use the same GET /quote pattern with the protocol’s vault/staking token as toToken.

​
General Pattern

Every vault deposit recipe follows the same pattern: 
GET /quote
  fromChain  = source chain ID
  toChain    = destination chain ID (same or different)
  fromToken  = token you're starting with
  toToken    = VAULT TOKEN ADDRESS (this triggers Composer)
  fromAmount = amount in smallest unit
  fromAddress = your wallet
  toAddress   = your wallet (receives vault tokens)
The only Composer-specific detail is that toToken must be a vault token address from a supported protocol. Everything else is identical to a standard LI.FI swap or bridge request.
