Try it out [here](/data-api/signature-aggregator/aggregate-signatures)! *** ### Jan 08th, 2025 **๐Ÿš€ 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. **๐Ÿ“Œ Get Started** * [List Latest Blocks for All Supported EVM Chains](https://developers.avacloud.io/data-api/evm-chains/list-latest-blocks-for-all-supported-evm-chains) * [List Latest Transactions for All Supported EVM Chains](https://developers.avacloud.io/data-api/evm-chains/list-latest-transactions-for-all-supported-evm-chains) 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! ๐Ÿš€ *** ### Dec 20th, 2024 **Token Reputation Analysis ๐Ÿ›ก๏ธ๐Ÿ”** Token Reputation Analysis Weโ€™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](/data-api/evm-balances/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** Hereโ€™s an example API call: ```bash theme={null} curl -X 'GET' \ 'https://glacier-api.avax.network/v1/chains/43114/addresses/0x51a679853D9582d29FF9e23ae336a0947BD0f337/balances:listErc20?pageSize=10&filterSpamTokens=true¤cy=usd' \ -H 'accept: application/json' | jq ``` As you can see in the response, the `$AVA` token is flagged as `Malicious`: ```json theme={null} { "erc20TokenBalances": [ { "ercType": "ERC-20", "chainId": "43114", "address": "0x397e48aF37b7d7660D0Aee74c35b2218D7EFca12", "name": "$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", "tokenReputation": "Benign" } ] } ``` Try it out [here](/data-api/evm-balances/list-erc-20-balances)! *** ### Nov 25th, 2024 **Avalanche9000 (Etna Upgrade ๐ŸŒ‹)** Avalanche9000 **New endpoint to list L1 validators:** * Added new endpoint to [list all or specific L1 validators](/data-api/primary-network/list-l1-validators) * Filters include `L1ValidationID`, `SubnetID`, `NodeID`, and `IncludeInactiveL1Validators`. **Updated transactions endpoint:** * [List latest transactions on the primary network](/data-api/primary-network-transactions/list-latest-transactions) 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](/data-api/etna) *** ### Oct 25th, 2024 **Data API new endpoint - Listing networks an address has interacted with** Returns a list of all networks on which an EVM address has had activity, filtering out networks with no activity for the provided address.

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](/data-api/evm-balances/list-erc-20-balances)! * **Primary Network**
In the [List Validators](/data-api/primary-network/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](/webhooks-api/webhooks/list-adresses-by-webhook) 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.
