Products that touch wallets typically ask:

Answering these has always been reasonably easy. RPC endpoints, indexers and wallet APIs have been around nearly as long as the chains themselves.

However, customers kept coming to us over a few challenges from existing solutions:

We’d already been providing custom datasets that solved these problems for a select number of institutions.

Today, a broader set of enriched datasets are now available to everyone.

Wallet transfer and balance feeds now available

Goldsky Feeds is a catalog of enriched, ready-to-use onchain datasets. Each data feed answers a question, in one normalized schema, and you can call as an API or stream into your own database.

 is the first, and it’s available today with two feeds:

Transfers and balances are the first two datasets in the catalog, with more wallet data and other themes to follow.

When you send a wallet address to the Feeds API, you get back every transfer it’s made and every token it currently holds:

There are two REST endpoints, called with your data API key.

Both accept a single address (and soon a comma-separated list) across all supported chains at once. Results page with keyset cursors at 100 rows by default and 1,000 max, and will return the same fields for both EVM and non-EVM chains. Balances responses also carry 

 for each address you query, covering the tokens that have a price.

 field tells you which family a row came from, which is important for a few fields that differ. On Solana for example, 

Streaming onchain wallet data into your own database

Streaming delivers the same feeds into a database you control, so your application reads wallet data locally without needing to call an API. Teams move to streaming for various reasons:

Holding every transfer and balance for every address you might need one day is expensive. Backfilling them on demand is slow, and someone has to own the job. We run the indexing and the backfills for every supported chain, so the full history for an address is available when you first request it.
