"The Transfers API makes Alchemy a no-brainer choice. With one call to alchemy\_getAssetTransfers, we retrieve comprehensive transaction histories - including internal transactions which were cumbersome and expensive requests." Phantom CTO and Co-Founder, Francesco Agosti
"Other providers just provide nodes as a service. Not only does Alchemy offer baseline infrastructure support, which is essential, but Alchemy adds an additional layer on top. For example, data on internal transactions (transactions that stem from contracts with deeper understanding of transactions)." ZenGo Co-Founder & CTO, Tal Be’ery
"Versus Etherscan’s API, we save $4,055 with Alchemy’s Transfers API annually. It's crucial that we give our customers a best-in-class experience. A key component of that is giving them their holistic transaction activity - so that they can use their Rainbow wallet to see what they own today and what they've traded in the past. Alchemy's Token API and Transfers API are the only web3 solutions that make this actually easy and possible. Any alternative method would require hundreds of thousands of calls and be exorbitantly expensive." Rainbow CTO, Wayne Cheng
Token API Fetch the token balance, metadata and allowances for any address Why it works No token list required: Alt methods require inevitably incomplete token lists to fetch contracts an address may ownEnriched off-chain data: Supplemented with CoinMarketCap data to reflect freshest on and off-chain data getTokenBalances to show any address’ real-time balances getTokenMetadata to show token symbols, names, decimals, etc.
Wallets use the Token API todisplay balances and metadata for all tokens for a given account Customers include Coinbase, Phantom, Robinhood, MyEtherWallet, Tally Ho, Ambire, ZenGo and Rainbow NFTs Analytics teams use the Token API to retrieve: Token balances and metadata across portfolios Token metadata across any tradable tokenCustomers include Dialog Analytics / Tooling Analytics / Tooling teams use the Token API to display and validate users’ token ownership and balances Customers include UniWhales and Worldcoin Token API Common use cases

It took us less than 30 minutes to set up and has led to faster, cheaper architecture for us and our customers.” COLLAB.LAND CO-FOUNDER RAYMOND FEND “Collab.Land needed a flexible webhook solution that is reliable at scale. Alchemy took our input and built Custom Webhooks. This unlocks entirely new capabilities for our product to more effectively and efficiently manage qualifying members for tokenized communities.” NORI CO-FOUNDER JAYCEN HORTON “With Alchemy's Custom Webhooks, we can instantly get notified about the most recent on-chain transactions and can merge that information with off-chain data. The key thing for us here is that this data is 100% reliable, so we know we can safely show it to our users in the frontend.”
Smart Websockets Connect and subscribe to get the real-time updates you care about Why it works Scalable offering client-side subscriptions so any number of clients can open connections, enabling linear scalability with front-endsNotifications across: Mined txns: notify when a txn has been minedPending txns: query the mempool to be notified on full pending txns (beyond txn hashes) New events and logs: monitor transfers and state changes to track users’ on-chain actions New heads: find out anytime a new block head is added to the chain
NFT apps use Smart Websockets to know when transactions are mined or when new blocks are available to instantly ingest the latest data Customers include OpenSea, Zora, NiftyKit and Mintify Analytics + Tooling Analytics / Tooling apps use Smart Websockets to ingest the latest block data at scale while avoiding repeated (and expensive) pollingCustomers include Omnia and Frame Wallets Wallets use Smart Websockets to notify users in a decentralized applications about their mined and dropped txnsCustomers include MyEtherWallet Smart Websocket Common use cases
