Wallets as a Service

Wallets as a Service (WAAS) lets you receive stablecoins, hold a USD balance, and pay out — without running wallet infrastructure or touching private keys. You create deposit addresses on supported chains. Confirmed deposits credit your merchant USD balance. To move money out, you quote a transfer and initiate a payout to a recipient you’ve whitelisted.

Core concepts

Addresses, balance, recipients, and transfers.

Create an address

How it works

Create a deposit address

Call the API to provision an address on a supported chain. Yara manages the keys.

Receive funds

Stablecoins sent to the address are confirmed and credited to your merchant USD balance. Your app is notified by webhook.

Whitelist a recipient

Add and approve the payout bank account or crypto address in the dashboard.

Quote, then transfer

Quote a payout to the recipient, then initiate the transfer from that quote.

Supported chains and assets

WAAS supports leading stablecoins across major networks. Fetch the live list from GET /v1/chains.

Deposit and transfer availability can differ per chain. The chains endpoint returns deposit_enabled and transfer_enabled flags so you always know what’s live.
