One integration.

import { avin} from '@avin/sdk'

const avin = new Avin({

apiKey: avin...',

chains: ['ethereum', 'solana', 'arbitrum'],

settlementToken: 'USDC'

})

// Create deposit address for a user

const deposit = await avin.deposits.create({

userId: 'user_8f72ab',

amount: 100, currency: 'USD',

expiresIn: '24h'

})

// → { eth: '0x...', sol: 'GHk...', arb: '0x...' }

avin.on('deposit.confirmed', (event) => {

creditUser(event.userId, event.usdAmount)

})
