We’ve just launched our Wallet Net-worth endpoint, allowing you to fetch the USD value of a wallet, across all chains and assets, with a single API call 🤯

This endpoint features three query parameters:

  • chains: specify multiple chains 🥳
  • exclude_spam: when set to true, this will exclude spam tokens from the calculation (recommended)
  • exclude_unverified_contracts: when set to true, this will exclude tokens that are not verified on CoinGecko (recommended)

Check-out the API reference for more information, and see this endpoint in action over on our YouTube channel.

We've launched a new endpoint for fetching ERC20 tokens by wallet which includes token balances, metadata, USD prices and a whole lot more for every token 🤩

Compared to our regular token balances endpoint, this endpoint includes the following extra data points per token:

  • balance_formatted: decimal formatted balance
  • usd_price: current price of the token
  • usd_price_24hr_percent_change: 24hr change as a percentage
  • usd_price_24hr_usd_change: 24hr change in usd value
  • usd_value: the value of the wallet's holdings
  • usd_value_24hr_usd_change: 24hr change in value of the wallet's holdings
  • portfolio_percentage: the percentage that this token represents of the wallet's token portfolio
  • native_token: this can be true or false and is used to identify the chain's native token

It also includes some powerful new query parameters:

  • exclude_spam: when set to true this will exclude all tokens marked as spam from the response (defaults to false)
  • exclude_unverified_contracts: when set to true this will exclude all tokens that are not verified on Coingecko (defaults to false)
  • exclude_native: when set to true this will exclude the chain's native token from the holdings (defaults to false)

Today we've launched a number of enhancements to our NFT collection endpoints 🔥 They include:

  • Richer NFT collection metadata
  • Expansion of verified_collection status across more chains
  • Token counts on NFT collections by wallet
  • Bulk fetch NFT collection metadata

Richer Collection Metadata​

We've added the following properties to our NFT Collection metadata:

  • collection_logo
  • collection_banner_image
  • collection_category
  • project_url
  • wiki_url
  • discord_url
  • telegram_url
  • twitter_username
  • instagram_username

Enhanced metadata can be found on the following endpoints:

Expansion of Verified Collections​

Our verified_collection status, which was previously only supported on Ethereum, is now available on these additional chains:

  • Polygon
  • Binance
  • Arbitrum
  • Avalanche
  • Optimism
  • Base

This status reflects whether or not the collection has been verified on OpenSea.

Token Counts​

We've introduced a new query parameter when fetching NFT Collections by wallet call token_counts. When set to true, this will add the total number of NFTs held in each collection by the wallet to the response data.

Bulk Fetch Collection Metadata​

We've added a new endpoint, Get metadata for multiple NFT Collections, that allows you to fetch metadata for up to 25 NFT collections in one request.

Today we've launched filtering and sorting across the many of our transfer and transaction endpoints 🚀

Filter by contract address​

Wallet transfer endpoints can now be filtered by specific contract addresses (one or many), allowing you to filter results down to specific contract(s). You'll find a new query parameter called contract_addresses on the following endpoints:

Sort by date​

All of our transfer and transaction endpoints can now be ordered by date asc/desc. Previously, all endpoints were sorted by desc as default, giving you the latest transactions first. Now, you can order these endpoints with order=asc to get the earliest transactions first. You'll find a new query parameter called order on the following endpoints:

On March 4, 2024, we will phase out our old public RPC URLs specific to WalletConnect within the earlier version of the Moralis JS SDK (v1). This update affects users that are currently using WalletConnect in the frontend who have not opted for a custom RPC URL. The RPC URLs slated for discontinuation follow the format: https://speedy-nodes-nyc.moralis.io/WalletConnect/eth/mainnet.

If you have already upgraded to our latest version of the JS SDK, or you do not use the WalletConnect feature in our v1 SDK, your operations will remain unaffected. For those still using these specific URLs, transitioning to a custom RPC URL is required. This can be easily achieved by updating the rpcMap parameter in the Moralis.authenticate method.

Summary and Migration Guide To migrate from the soon-to-be-retired speedy nodes, users are required to replace these deprecated URLs with an alternative RPC provider. This process involves specifying your chosen provider's RPC URL in the rpcMap parameter during authentication with Moralis. This change ensures continuous and uninterrupted service following the deprecation date. Please refer to our migration guide for more information.

We've launched a new endpoint that allows you to fetch SPL Token metadata on Solana 🔥

In the same way you could already fetch NFT metadata, it's now possible to fetch metadata for all SPL tokens. For each token we return:

  • Mint
  • Standard
  • Name
  • Symbol
  • Metaplex details

We are aware of a bug on our current NFT Metadata endpoint, which returns SPL Token metadata for certain tokens. If you are using the NFT endpoint in this way, we strongly advise that you begin using the new SPL Token Metadata endpoint.

Try it out over on our Solana swagger.

Starting today, September 11th, 2023, we're implementing a series of significant API changes to v2 of our EVM API as described in an earlier post. Some of these changes are breaking changes, but will ultimately provide you with a faster, more reliable, and more consistent experience.

If you are on API v2 and are impacted by these changes you can find a comprehensive migration guide here.

For those who have transitioned to v2.2, rest assured that your operations remain unaffected by these updates.

We’re excited to announce that v2.2 of our EVM API is officially live and ready for immediate integration into your applications.

New features in v2.2​

As part of v2.2, we've introduced 5 new endpoints designed to provide total counts for popular use-cases related to Wallets, NFTs, ERC20s and Blocks. These endpoints are particularly valuable for those who will be impacted by the breaking changes coming to v2 in September, and are available now allowing for a smooth migration:

These new endpoints can be found at our latest v2.2 swagger https://deep-index.moralis.io/api-docs-2.2

Extended Deadline for Breaking Changes​

We initially announced that breaking changes would be rolled out on September 4th. However, in order to maximize the window for you to integrate these new endpoints, we're pushing the date for breaking changes to September 11th. This gives you two weeks to integrate the new endpoints into your applications, as previously outlined in our earlier post.

Continuation of v2​

Starting from September 11th, v2 will still be operational, but it will incorporate the announced breaking changes and deprecated endpoints will be removed. For most customers who are not impacted by these updates, it's perfectly safe to continue using v2. However, we strongly recommend upgrading to the latest version to benefit from all the new features and improvements.

Summary​

  • API v2.2 is now available
  • New endpoints for total counts are available in v2.2.
  • Breaking changes will now be rolled out on September 11th, giving you an extra week to prepare.
  • Version 2 will continue to be operational but will incorporate breaking changes and deprecated endpoints will be removed, starting September 11th.
  • If you are not affected by the breaking changes outlined here, you can continue to use v2 safely.
  • Full migration guide can be found here.

Our NFT API now includes a new property called verified_collections 🎉 This property can be true or false, and reflects whether or not the collection has been verified on OpenSea. This new property can be found on all NFT endpoints.

Additionally, we have added a new query parameter called exclude_spam. When this is set to true, any NFTs that have been marked as spam will be excluded from the API response. This query parameter is currently available on get NFTs by wallet as well as get NFT collections by wallet.

Our ERC20 transfers, NFT transfers and transaction endpoints have just got an upgrade!

All endpoints that currently return a to_address and/or from_address will now include an additional to_address_label and from_address_less respectively 🤩

These labels reflect publicly known addresses such as Coinbase, Binance, Uniswap v3, 1inch etc; as well as specific addresses such as Uniswap v2: Router 2 🔥

Perfect for adding extra detail into your wallet applications and transaction analytics 🙌

From today you can now easily establish a wallet's age as well as detect which chains it has been active on 🔥

This latest endpointadded to our Wallet API, /wallets/{address}/chains, is our first truly cross-chain API. Rather than the usual chain query parameter, it has a new chains parameter, allowing you to specify one or many chains in one API call 🤩

For each chain that a wallet has been detected on, we return its first_transaction details and last_transaction details.

Perfect for wallet analytics, user engagement, wallet age gated sites plus so much more 🙌

Today we're excited to announce a number of improvements to our ERC20 price endpoints 🎉

Fetch multiple ERC20 prices​

We've added a new endpoint, /erc20/prices, that allows you to fetch the prices of up to 25 ERC20s in one API call. No more fetching prices one by one 😍

24hr change​

We've added 24hrPercentChange to all of our price endpoints, so you can now easily fetch a token's 24 hour performance. We've introduced a new query parameter, include=percent_change, which when included will add 24hrPercentChange to the response body. Note: using this query parameter incurs an additional cost of +5 CUs per request.

Today we have enriched all our ERC20 endpoints with extra metadata including token name, symbol, icon, and decimals 🎉

Developers can now more easily identify the specific ERC20 tokens involved in transfers, mints, burns, and approvals without having to make additional API calls.

Previously, token metadata were only available through the ERC20 metadata endpoint.

This metadata is now available on the following endpoints:

Our Resolve API now supports Ethereum Name Service (ENS) lookup by domain. This new feature allows you to input a .eth domain and receive the associated Ethereum address 🎉

To use this new endpoint, simply make a GET request to /api/v2/resolve/ens/{domain} with your desired .eth domain appended.

For example, if you want to look up the address for vitalik.eth, you would make a GET request to: /api/v2/resolve/ens/vitalik.eth, which would return the address 0x057Ec652A4F150f7FF94f089A38008f49a0DF88e.

We're excited to announce the launch of our new spam detection feature across our EVM APIs!

Our latest update adds a new field called possible_spam to all ERC20s and NFTs. This field returns true or false, depending on whether the contract address is associated with spam, phishing attempts, or suspicious activities.

This feature is currently available on our EVM API and will soon be launching on our Streams API 🔥 Stay tuned!

Check out our docs for more information about this feature including which endpoints it's active on.

As outlined in an earlier update, today we've made a change to the default behaviour of disable_total on a number of endpoints in order to vastly improve their response times.

This flag now defaults to true and the total response will be returned as null. Customers wanting to continue using the total will need to specify disable_total=false in their requests.

· 2 min read

In order to vastly improve the response times on a number of endpoints (by up to x10!), we are planning to phase out support for total within our API responses.

A new flag called disable_total exists on the below endpoints which defaults to false. When users set this to true, the total count from the response will return as null, and the endpoint's response time is greatly improved. We strongly recommend to begin using this flag.

More CUs for our amazing customers!

After considerations on the great demand of the getTokenIdOwners endpoint, we understand that a lot of our users are very keen to make full use of this endpoint.

Therefore, we have decided to reduce our CU cost for /nft/{address}/{token_id}/owners (getTokenIdOwners) from 20 CUs down to 5 CUs.

We just made working with NFT metadata a breeze! 💨 Get predictable, structured outputs at each endpoint thanks to our new built-in NFT API Metadata Normalization.

Taking the original source metadata field, which comes through the API as a string with an unpredictable format, we now output this into a nice clean, predictable object on the below endpoints - meaning it's now much easier for you to work with NFT metadata!

You'll find a new query parameter named normalizeMetadata on the below endpoints. When this is set to true, we normalize and transform the source metadata into a standardized structure (based on ERC721, CryptoPunks, OpenSea etc) and output this in a new object called normalized_metadata
