Service Setup

import AaveProtocolEvm from '@tetherto/wdk-protocol-lending-aave-evm'
import { WalletAccountEvm } from '@tetherto/wdk-wallet-evm'

// Create wallet account first

Account Configuration

The service uses the wallet account configuration to connect to the target network and sign transactions.

import { WalletAccountEvm, WalletAccountReadOnlyEvm } from '@tetherto/wdk-wallet-evm'

// Full access account
const account = new WalletAccountEvm(seedPhrase, "0'/0/0", {
  provider: 'https://ethereum-rpc.publicnode.com'
})

// Read-only account (quotes, reads)
const readOnly = new WalletAccountReadOnlyEvm('0xYourAddress', {
  provider: 'https://ethereum-rpc.publicnode.com'
})

const aave = new AaveProtocolEvm(account)

ERC‑4337 (Account Abstraction)

When using ERC‑4337 smart accounts, you can optionally specify a paymasterToken per operation to sponsor gas.

import { WalletAccountEvmErc4337 } from '@tetherto/wdk-wallet-evm-erc-4337'

const aa = new WalletAccountEvmErc4337(seedPhrase, "0'/0/0", {
  chainId: 1,
  provider: 'https://arb1.arbitrum.io/rpc',
  bundlerUrl: 'YOUR_BUNDLER_URL',
  paymasterUrl: 'YOUR_PAYMASTER_URL'
})

const aaveAA = new AaveProtocolEvm(aa)

const result = await aaveAA.supply({ token: '0xdAC17F...ec7', amount: 1000000n }, {
  paymasterToken: 'USDT'
})
