Base wallet API

C2

Everything a Base wallet needs without building an indexer: native and token balances, net-worth, full transaction history and approval state — returned as structured JSON, ready to render.

Balances and net-worth

Fetch native ETH and token balances plus a priced net-worth for any Base address in a single call, so wallet home screens load without a data pipeline.

History and approvals

Paginated, decoded transaction history and current token approvals let wallets show activity and surface risky allowances users should revoke.

Frequently asked

Can I get a full token portfolio for a Base address?

Yes — token holdings with prices and a net-worth total come back in one wallet call.

Do I need to run an indexer for Base history?

No — decoded Base transaction history is served directly, no indexer to build or maintain.
