Copy-paste ready code snippets for immediate implementation
// Supply LBTC to Aave on Base
const [supply] = useAaveSupply();
const result = await supply({
market: '0x18cd499e3d7ed42feba981ac9236a278e4cdc2ee', // Base Pool
token: '0x...', // LBTC address
amount: '1000000000000000000', // 1 LBTC
user: userAddress
});
console.log('Supply successful:', result);Supply LBTC tokens to Aave lending pool on Base network
// Generate Bitcoin deposit address for LBTC staking
const signature = await signStakeAndBakeMessage({
userDestinationAddress: address,
chainId: 8453 // Base
});
const depositAddress = await generateDepositBtcAddress({
address: userAddress,
chainId: 8453,
signature: signature
});
console.log('Deposit BTC to:', depositAddress);Initialize Lombard SDK and generate deposit address for LBTC minting
// Multi-network LBTC yield optimization
// 1. Mint LBTC on Base
const baseLBTC = await lombard.mintLBTC({
network: 'base',
amount: btcAmount
});
// 2. Bridge to Sui for additional yield
const suiYield = await lombard.bridgeToSui({
amount: baseLBTC.amount,
targetProtocol: 'SuiLend'
});
console.log('Cross-chain yield active');Advanced cross-chain strategy combining Base Aave lending with Sui DeFi yields
Batch multiple operations and use appropriate gas limits for different networks
Always validate contract addresses and implement proper error handling
Track APY changes and rebalance positions for optimal returns
