A custody wallet platform for exchanges and digital-asset apps

Multi-chain wallets,
made simple.

For exchanges and digital-asset applications, connect deposit addresses, deposit notifications, sweeps and on-chain withdrawals. One API, wired into your product.

Focus on your product. We take care of the wallet.

Wallet operations

From the first deposit to scaled operations

One clear wallet-operations path that keeps multi-chain complexity backstage.

Every step is observable, and every movement of funds leaves a record (illustrative data, not real customers).

Deposit addresses are issued per user ID you own, and credit automatically after on-chain confirmation
New addresses join monitoring automatically, and deposits are notified to your business by callback
Sweeps and treasury-pool dispatch happen inside your tenant, cutting manual transfers
On-chain withdrawal status is notified by callback, with progress and results you can query

Use cases

Three typical scenarios

Whether you run an exchange, a digital-asset app, or business treasury operations, it is the same API.

Exchange

Deposits and withdrawals for users

Open deposit addresses per required network, get notified as deposits arrive, and run withdrawals through policy-based approval.

Multi-chain addressesAutomatic deposit alertsPolicy-based approvals
Digital-asset app

Embed wallet capabilities

Use the API to add a multi-chain wallet; users stay in your app to deposit, withdraw and check history.

Business treasury

Internal transfers and treasury pool

Run internal transfers and centralised dispatch inside the tenant treasury pool to reduce manual work and steady your operations.

Core capabilities

One API that keeps multi-chain complexity backstage

Wallet infrastructure built for scaled operations.

Keep the complexity backstage. Hand you a clear interface.

01

Unified custody

Custody multi-chain assets in one place, with addresses, balances and statements managed together.

02

Automatic monitoring and callback notifications

New deposit addresses join monitoring automatically, and deposits and transaction status are notified to your systems by callback.

03

Treasury dispatch

Internal transfers and centralised dispatch inside the tenant treasury pool give your funding a steady rhythm.

04

EIP-7702 gas delegation

On supported networks, manage gas delegation centrally for sweeps and withdrawals. Gas is paid from the tenant gas wallet, not funded for free by the platform; the actual scope follows your tenant activation and delegation status, and platform configuration is only the tenant default.

These capabilities depend on the networks, assets and configuration actually activated; chains and assets that are not activated are out of scope.

Integration path

Integrate in three steps

From docs to production, the path is clear.

  1. 1

    Align on requirements

    Confirm the networks, assets and use cases you need, and activate your account.

  2. 2

    Connect the API

    Configure API keys, obtain deposit addresses and wire up callbacks.

  3. 3

    Validate and launch

    Run deposit, sweep and withdrawal integration tests, then confirm production settings.

Engineers can start right here.

Quickstart, API reference, callback verification and the OpenAPI spec. The integration docs are currently in Chinese.

FAQ

Frequently asked questions

What kind of business is it for?

It suits exchanges and apps that need to offer their users digital-asset wallets, deposits and withdrawals. You keep your product and user system and add wallet capabilities through the API.

Do users need another app?

No. Your systems use the wallet through the API, and users keep operating inside your product.

How are fees decided?

Fees depend on your business configuration, networks and assets, and are confirmed before activation. Deposit and withdrawal costs are borne by the user; platform configuration is the tenant default.
