Wallet infrastructure API

Everything a wallet needs from one key: read balances and net-worth, surface risky approvals, simulate a transaction before sending, then build, sign and broadcast it.

Primitives that power it
  • Balances / portfolio / net-worthC1
  • Approvals / value-at-riskC2
  • Simulate tx (preview)C2
  • Build / sign / broadcastC2

Show an accurate portfolio

Net-worth values balances using the built-in price layer, so you don't join a separate market-data vendor to display a portfolio.

Protect users from bad approvals

Surface outstanding token approvals and value-at-risk so users can revoke dangerous allowances before they're drained.

Preview before you send

Simulate a transaction to show users the expected outcome and catch reverts or unexpected transfers ahead of broadcast.

Frequently asked

Which chains are supported for signing and broadcast?

Bitcoin, Ethereum and TRON run on our own nodes, with build/sign/broadcast on the processing plane.

Can I value holdings without a separate price API?

Yes — net-worth uses the integrated price primitives on the same key.

Self-serve. Pay in crypto or card. Metered by credits — heavy primitives cost more, simple ones are cheap.
