🚀 New API Endpoints: Aggregated Transactions & Blocks Across L1 Chains & Avalanche C-Chain Aggregated Transactions & Blocks We’re excited to introduce two new API endpoints that provide aggregated transaction and block data across all supported L1 chains and the Avalanche C-Chain! These endpoints allow developers to query, filter, and sort blockchain data efficiently, unlocking powerful insights across multiple chains. 📌 Get Started These enhancements simplify multi-chain data retrieval, making it easier for developers to build cross-chain analytics, wallets, and monitoring tools. Try them out today and streamline your blockchain data integration! 🚀

Token Reputation Analysis 🛡️🔍 Token Reputation Analysis We’re thrilled to introduce Token Reputation Analysis, a new feature for identifying potential security risks with ERC20 tokens on the Avalanche C-Chain! This update adds a new field, tokenReputation, to the List ERC-20 balances response. The field categorizes tokens into the following reputations:
  • Benign: Tokens considered safe based on security analysis.
  • Malicious: Tokens flagged for suspicious activity, spam, or phishing.
  • null: Reputation unknown.
Example Usage Here’s an example API call: 
curl -X 'GET' \
  'https://glacier-api.avax.network/v1/chains/43114/addresses/0x51a679853D9582d29FF9e23ae336a0947BD0f337/balances:listErc20?pageSize=10&filterSpamTokens=true&currency=usd' \
  -H 'accept: application/json' | jq
As you can see in the response, the $AVA token is flagged as Malicious: 
{
  "erc20TokenBalances": [
    {
      "ercType": "ERC-20",
      "chainId": "43114",
      "address": "0x397e48aF37b7d7660D0Aee74c35b2218D7EFca12",
      "name": "$AVA (https://avalaunch.farm)",
      "symbol": "$AVA",
      "decimals": 2,
      "balance": "8200000",
      "tokenReputation": "Malicious"
    },
    {
      "ercType": "ERC-20",
      "chainId": "43114",
      "address": "0xB97EF9Ef8734C71904D8002F8b6Bc66Dd9c48a6E",
      "name": "USD Coin",
      "symbol": "USDC",
      "decimals": 6,
      "balance": "1515448052896",

    }

Avalanche9000 (Etna Upgrade 🌋) Avalanche9000 New endpoint to list L1 validators: Updated transactions endpoint:
  • List latest transactions on the primary network now supports l1ValidationID to fetch transactions linked to specific L1 validators (e.g., ConvertSubnetToL1Tx).
  • L1 transactions are sorted in descending order with additional filters like timestamp and txTypes.
Enhanced transaction properties:
  • P-Chain Transaction responses now include:
    • L1 validator details (validationID, nodeID, weight, balances, etc.).
    • Burned AVAX details for increasing L1 validator balance.
    • Validator manager details (BlockchainID and ContractAddress).
New block properties:
  • P-Chain blocks now include:
    • ActiveL1Validators (total active L1 validators).
    • L1ValidatorsAccruedFees (fees from active L1 validators).
New subnet properties:
  • Subnet details now have:
    • IsL1 to indicate if a subnet has been converted to an L1.
    • Validator manager details for L1 subnets.
These changes support seamless management and visibility of L1 validators introduced in the Etna upgrade. For more details, see here

Filter spam tokens and new endpoints for the primary network The following improvements have been made to the Glacier API:
  • EVM
    Remove Spam Tokens from Balances Endpoint     Users can now pass in an optional query parameter filterSpamTokens when getting balances for a particular address to filter out balances of tokens that we’ve determined to be spam. By default, the route will now filter spam tokens unless filterSpamTokens=false. Try it out here!
  • Primary Network
    In the List Validators endpoint, users can now sort validators by Block Index, Delegation Capacity, Time Remaining, Delegation Fee, or Uptime Performance.     Users can also filter by validator uptime performance using minUptimePerformance and maxUptimePerformance and by fee percentage using minFeePercentage and `maxFeePercentage.
  • Webhooks
    A new API endpoint has been added to enable users to list all addresses associated with a webhook.

​
Aug 20th, 2024

Webhook service launched With Glacier Webhooks, you can monitor real-time events on the Avalanche C-chain and L1s. For example, you can monitor smart contract events, track NFT transfers, and observe wallet-to-wallet transactions. webhooks Key Features:
  • Real-time notifications: Receive immediate updates on specified on-chain activities without polling.
  • Customizable: Specify the desired event type to listen for, customizing notifications according to individual requirements.
  • Secure: Employ shared secrets and signature-based verification to guarantee that notifications originate from a trusted source.
  • Broad Coverage: Support for C-chain mainnet, testnet, and L1s within the Avalanche ecosystem, ensuring wide-ranging monitoring capabilities.
Use cases
  • NFT Marketplace Transactions: Get alerts for NFT minting, transfers, auctions, bids, sales, and other interactions within NFT marketplaces.
  • Wallet Notifications: Receive alerts when an address performs actions such as sending, receiving, swapping, or burning assets.
  • DeFi Activities: Receive notifications for various DeFi activities such as liquidity provisioning, yield farming, borrowing, lending, and liquidations.
