LIFI_API_KEY	API key for higher rate limits	No
LIFI_INTEGRATOR	Integrator ID for analytics	No

💎 Integrator Fee Configuration

This skill includes a small integrator fee (0.3%) on swaps to support development. The fee is transparently disclosed to users before each transaction.

Variable	Value	Description
INTEGRATOR_ID	CyberPay	Integrator identifier (registered at portal.li.fi)
INTEGRATOR_FEE	0.003	0.3% integrator fee
FEE_RECIPIENT	0x890CACd9dEC1E1409C6598Da18DC3d634e600b45	EVM wallet to receive fees

Fee Breakdown:

• User pays: 0.3% of swap output
• Integrator receives: 100% of fee (after LI.FI service fee)

💡 Fees are accumulated in the LI.FI contract and can be withdrawn via the LI.FI Portal or API.

Features

• 🌉 Cross-Chain Bridges - 15+ bridge protocols
• 🔄 DEX Aggregation - Best rates across DEXs
• ⛓️ 30+ Chains - Ethereum, Arbitrum, Polygon, Solana, etc.

Supported Chains

Chain	ID	Native Token
Ethereum	1	ETH
Arbitrum	42161	ETH
Optimism	10	ETH
Polygon	137	MATIC
BSC	56	BNB
Avalanche	43114	AVAX
Base	8453	ETH
zkSync Era	324	ETH
Solana	1151111081099710	SOL

Supported Bridges

Bridge	Chains	Speed
Stargate	8+	~1-5 min
Hop	6+	~5-15 min
Across	7+	~2-5 min
Celer	15+	~5-20 min
Connext	10+	~10-30 min
Multichain	20+	~10-30 min
Hyphen	5+	~2-5 min
Synapse	15+	~5-15 min

Execute Transaction

After getting a quote, execute the transaction:

# The quote response includes transaction data
QUOTE_RESPONSE=$(curl -s "https://li.quest/v1/quote?...")

# Extract transaction data
TX_DATA=$(echo "$QUOTE_RESPONSE" | jq -r '.transactionRequest')

# Send transaction using your wallet/web3 provider
# This requires a signing mechanism (MetaMask, ethers.js, etc.)

Check Transaction Status

TX_HASH="0x..."
FROM_CHAIN="1"
TO_CHAIN="42161"

curl -s "https://li.quest/v1/status" \
  -G \
  --data-urlencode "txHash=${TX_HASH}" \
  --data-urlencode "fromChain=${FROM_CHAIN}" \
  --data-urlencode "toChain=${TO_CHAIN}" | jq '{
    status: .status,
    substatus: .substatus,
    sending: .sending,
    receiving: .receiving
  }'

Status Codes

Status	Description
NOT_FOUND	Transaction not indexed yet
PENDING	Transaction in progress
DONE	Successfully completed
FAILED	Transaction failed

Route Options

Option	Values	Description
order	RECOMMENDED, FASTEST, CHEAPEST, SAFEST	Route priority
slippage	0.01 - 0.5	Slippage tolerance (1-50%)
maxPriceImpact	0.01 - 0.5	Max price impact
allowBridges	stargate, hop, etc.	Whitelist bridges
denyBridges	multichain, etc.	Blacklist bridges

Gas Estimation

# Get gas prices for a chain
CHAIN_ID="1"

curl -s "https://li.quest/v1/gas/prices?chainId=${CHAIN_ID}" | jq '.'

Token Approval

Before swapping, approve token spending:

# Get approval transaction data
curl -s "https://li.quest/v1/approval/transaction" \
  -G \
  --data-urlencode "chainId=1" \
  --data-urlencode "tokenAddress=0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48" \
  --data-urlencode "amount=100000000" | jq '.data'

Safety Rules

1. ALWAYS display route details before execution
2. WARN if price impact > 1%
3. WARN if slippage > 3%
4. CHECK bridge security ratings
5. VERIFY destination address

Error Handling

Error	Cause	Solution
NO_ROUTES	No available routes	Try different tokens/chains
INSUFFICIENT_LIQUIDITY	Low liquidity	Reduce amount
SLIPPAGE_EXCEEDED	Price moved	Increase slippage
BRIDGE_UNAVAILABLE	Bridge down	Try different bridge
