Set Token Pool rate limits using Hardhat

Guide Versions

This guide is available in multiple versions. Choose the one that matches your needs.

This tutorial will guide you through the process of updating the rate limiter settings for outbound and inbound transfers in your deployed token pools using Hardhat. You will first review existing rate limiter settings and then update them.

Prerequisites

Before You Begin

  1. Make sure you have Node.js v18 or above installed. If not, install Node.js v18:
    Download Node.js 18 if you don't have it installed. Optionally, you can use the nvm package to switch between Node.js versions:

    nvm use 18
    

    Verify that the correct version of Node.js is installed:

    node -v
    

    Example output:

    $ node -v
    v18.7.0
    
  2. Clone the repository and navigate to the project directory:

    git clone https://github.com/smartcontractkit/smart-contract-examples.git
    cd smart-contract-examples/ccip/cct/hardhat
    
  3. Install dependencies for the project:

    npm install
    
  4. Compile the project:

    npm run compile
    
  5. Encrypt your environment variables for higher security:
    The project uses @chainlink/env-enc to encrypt your environment variables at rest. Follow the steps below to configure your environment securely:

    1. Set an encryption password for your environment variables:

      npx env-enc set-pw
      
    2. Set up a .env.enc file with the necessary variables for Avalanche Fuji and Arbitrum Sepolia testnets. Use the following command to add the variables:

      npx env-enc set
      

      Variables to configure:

      • AVALANCHE_FUJI_RPC_URL: A URL for the Avalanche Fuji testnet. You can get a personal endpoint from services like Alchemy or Infura.
      • ARBITRUM_SEPOLIA_RPC_URL: A URL for the Arbitrum Sepolia testnet. You can get a personal endpoint from services like Alchemy or Infura.
      • PRIVATE_KEY: The private key for your testnet wallet. If you use MetaMask, you can follow this guide to export your private key. Note: This key is required for signing transactions like token transfers.
  6. Fund your EOA with native gas tokens:
    Make sure your EOA has enough native gas tokens on Avalanche Fuji to cover transaction fees. You can use the Chainlink faucets to get testnet tokens.

Tutorial

Review current rate limiter settings

Use the getCurrentRateLimits task to fetch the current rate limiter states for a specific chain from a token pool. This task provides detailed information about both inbound and outbound rate limits, including:

  • Whether rate limiting is enabled
  • The maximum capacity (bucket size)
  • The refill rate (tokens per second)
  • Current token amount in the bucket
  • Last update timestamp

Below is an explanation of the parameters used:

ParameterDescriptionDefaultRequired
pooladdressThe address of the token pool to query.N/AYes
remotechainThe remote blockchain to check rate limits for (e.g., arbitrumSepolia for Fuji pool).N/AYes
networkThe blockchain on which to execute the query (e.g., avalancheFuji, arbitrumSepolia).N/AYes
  1. Get rate limiter settings for the token pool on Avalanche Fuji:

    npx hardhat getCurrentRateLimits \
      --pooladdress 0x1aFafBAd2528747cf464F62e9e57238FDE8f2BA9 \
      --remotechain arbitrumSepolia \

Update rate limiter settings

Use the updateRateLimiters task to update the rate limiter configurations for an existing chain connection in your token pool. This task specifically interacts with the setChainRateLimiterConfig function of the TokenPool contract, allowing you to adjust the rate limits without altering other configurations like remote pool addresses.

The updateRateLimiters task allows you to:

  • Enable or disable rate limiting for outbound or inbound transfers or both.
  • Set the capacity and rate for the rate limiters, controlling the flow of tokens.
  • Target a specific remote chain, updating rate limits for that chain only.

Below is an explanation of the parameters used during the rate limiter update process:

ParameterDescriptionDefaultRequired
pooladdressThe address of the token pool being configured.N/AYes
remotechainThe remote blockchain to which this pool is linked. Examples include avalancheFuji, arbitrumSepolia, baseSepolia, and sepolia.N/AYes
ratelimiterSpecifies which rate limiters to update: inbound, outbound, or both.bothNo
outboundratelimitenabledA flag indicating whether to enable outbound rate limits for cross-chain transfers (true or false).falseNo
outboundratelimitcapacityThe maximum number of tokens allowed in the bucket for outbound transfers (in wei). Note: Applicable if outbound rate limits are enabled.0No
outboundratelimitrateThe number of tokens per second that the bucket is refilled for outbound transfers (in wei). Note: Applicable if outbound rate limits are enabled.0No
inboundratelimitenabledA flag indicating whether to enable inbound rate limits for cross-chain transfers (true or false).falseNo
inboundratelimitcapacityThe maximum number of tokens allowed in the bucket for inbound transfers (in wei). Note: Applicable if inbound rate limits are enabled.0No
inboundratelimitrateThe number of tokens per second that the bucket is refilled for inbound transfers (in wei). Note: Applicable if inbound rate limits are enabled.0No
networkThe blockchain network where the local token pool is deployed. Examples include avalancheFuji, arbitrumSepolia, baseSepolia, and sepolia.N/AYes

Command syntax:

npx hardhat updateRateLimiters \
  --pooladdress <POOL_ADDRESS> \
  --remotechain <REMOTE_CHAIN> \
  --ratelimiter <inbound/outbound/both> \
  --outboundratelimitenabled <true/false> \
  --outboundratelimitcapacity <OUTBOUND_CAPACITY> \
  --outboundratelimitrate <OUTBOUND_RATE> \
  --inboundratelimitenabled <true/false> \
  --inboundratelimitcapacity <INBOUND_CAPACITY> \
  --inboundratelimitrate <INBOUND_RATE> \
  --network <NETWORK_NAME>

Example command:

Suppose you want to enable inbound and outbound rate limits for your token pool on Avalanche Fuji to control the number of tokens received or sent from/to Arbitrum Sepolia. We will use an existing token pool that interacts with an ERC20 token with 18 decimals:

  • Token Pool on Avalance Fuji:

    • Outbound Rate Limiter:

      • Enabled: true
      • Capacity: 10000000000000000000 wei (equivalent to 10 tokens, based on 18 decimals)
      • Rate: 100000000000000000 wei (equivalent to 0.1 token per second, based on 18 decimals)
      • Note:
        • Capacity / Rate = 10 / 0.1 = 100 seconds
        • It takes 100 seconds to replenish the bucket from 0 to full capacity.
    • Inbound Rate Limiter:

      • Enabled: true
      • Capacity: 20000000000000000000 wei (equivalent to 20 tokens, based on 18 decimals)
      • Rate: 100000000000000000 wei (equivalent to 0.1 tokens per second, based on 18 decimals)
      • Note:
        • Capacity / Rate = 20 / 0.1 = 200 seconds
        • It takes 200 seconds to replenish the bucket from 0 to full capacity.
  • Token Pool on Arbitrum Sepolia: Rate limits are the same as the Avalanche Fuji pool, but the inbound and outbound settings are swapped.

    • Outbound Rate Limiter:
      • Enabled: true
      • Capacity: 20000000000000000000 wei
      • Rate: 100000000000000000 wei
    • Inbound Rate Limiter:
      • Enabled: true
      • Capacity: 10000000000000000000 wei
      • Rate: 100000000000000000 wei
  1. Update rate limiter settings for the token pool on Avalanche Fuji: Replace <POOL_ADDRESS> with your token pool address.

    npx hardhat updateRateLimiters \
      --pooladdress <POOL_ADDRESS> \
      --remotechain arbitrumSepolia \
      --ratelimiter both \
      --outboundratelimitenabled true \
      --outboundratelimitcapacity 10000000000000000000 \
      --outboundratelimitrate 100000000000000000 \
      --inboundratelimitenabled true \
      --inboundratelimitcapacity 20000000000000000000 \
      --inboundratelimitrate 100000000000000000 \
      --network avalancheFuji

Test the rate limiter settings

To verify the rate limiter settings, initiate a cross-chain transfer between the token pools on Avalanche Fuji and Arbitrum Sepolia. The rate limiter configuration will control the flow of tokens between these pools.

Note: Ensure that your externally owned account (EOA) has a sufficient balance of ERC20 tokens on Avalanche Fuji to complete the transfer.

In the example below, we use a token pool at address 0xa6aca9013b111228433da2aea186cb267d74fc0f on Avalanche Fuji, which has burn and mint privileges for the token at address 0xcb19276d94d82bd0aceb9fd960df6c69e42ee1c6. We will transfer this token from Avalanche Fuji to Arbitrum Sepolia. For your own test, substitute these addresses with the token pool and token addresses that you have deployed.

  1. Test Capacity: Because the outbound capacity set is 1000000000000000000000 , let's transfer 1000000000000000000001 tokens from Avalanche Fuji to Arbitrum Sepolia. This transfer should fail because the capacity is less than the number of tokens being transferred.

    Command:

    npx hardhat transferTokens --tokenaddress <TOKEN_ADDRESS> --amount 1000000000000000000001 --destinationchain arbitrumSepolia --receiveraddress <RECEIVER_ADDRESS> --network avalancheFuji
    

    Expected output:

    $ npx hardhat transferTokens --tokenaddress 0x16F6b0f41b9217857551e29F38F99975a2fc9add --amount 1000000000000000000001 --destinationchain arbitrumSepolia --receiveraddress 0x9d087fC03ae39b088326b67fA3C788236645b717 --network avalancheFuji

    Notice in the logs that the transfer failed because the capacity was exceeded: TokenMaxCapacityExceeded.

  2. Test Rate: Now, let's transfer 10000000000000000000 tokens from Avalanche Fuji to Arbitrum Sepolia, which will empty the bucket. After this transfer, we will attempt to transfer another 10000000000000000000 tokens. This transfer will fail because it takes 100 seconds to replenish the bucket.

    1. First transfer (Successful):

      Command:

      npx hardhat transferTokens --tokenaddress <TOKEN_ADDRESS> --amount 10000000000000000000 --destinationchain arbitrumSepolia --receiveraddress <RECEIVER_ADDRESS> --network avalancheFuji
