mcAaveV3Pool

A pre-configured multichain contract instance for interacting with Aave V3 Pool contracts across different networks. This allows you to perform lending and borrowing operations across multiple chains using a unified interface.

export const mcAaveV3Pool = getMultichainContract<typeof AavePoolAbi>({
  abi: AavePoolAbi,
  deployments: [
    ["0x794a61358D6845594F94dc1DB02A252b5b4814aD", optimism.id],
    ["0xA238Dd80C259a72e81d7e4664a9801593F98d1c5", base.id],
    ["0x794a61358D6845594F94dc1DB02A252b5b4814aD", polygon.id],
    ["0x794a61358D6845594F94dc1DB02A252b5b4814aD", arbitrum.id]
  ]
})

Usage

import { mcAaveV3Pool } from "@biconomy/abstractjs"
import { optimism } from "viem/chains"
 
// Supply assets to Aave
const supplyInstruction = await mcAaveV3Pool.build({
  type: "supply",
  data: {
    chainId: optimism.id,
    args: [
      tokenAddress,    // address of the token to supply
      amount,          // amount to supply
      userAddress,     // address receiving the aToken
      0               // referral code
    ]
  }
})

Parameters

Common parameters for building instructions:

Parameter	Type	Description
type	`string`	The function name to call (e.g., "supply", "borrow", "repay")
data.chainId	`number`	The chain ID where the transaction should be executed
data.args	`any[]`	The arguments for the function call

Response

The contract provides access to all Aave V3 Pool functions, including:

Function	Description
supply	Supply assets to the protocol
borrow	Borrow assets from the protocol
repay	Repay borrowed assets
withdraw	Withdraw supplied assets
getUserAccountData	Get user's lending/borrowing positions

Example

Here's a complete example showing how to supply and borrow assets:

import { mcAaveV3Pool } from "@biconomy/abstractjs"
import { optimism } from "viem/chains"
 
// Supply USDC to Aave
const supplyOp = await mcAaveV3Pool.build({
  type: "supply",
  data: {
    chainId: optimism.id,
    args: [
      usdcAddress,
      parseUnits("100", 6),  // 100 USDC
      userAddress,
      0
    ]
  }
})
 
// Borrow ETH against the supplied collateral
const borrowOp = await mcAaveV3Pool.build({
  type: "borrow",
  data: {
    chainId: optimism.id,
    args: [
      wethAddress,
      parseEther("0.1"),     // 0.1 ETH
      2,                     // variable rate mode
      0,                     // referral code
      userAddress
    ]
  }
})

Error Handling

The contract will throw an error if:

Attempting to interact with an unsupported chain
Insufficient collateral for borrowing
Invalid function parameters
Unsupported interest rate mode
