Multi-chain stablecoin custody wallet system
Built for member top-ups, game credits, cross-border commerce, and digital businesses. UUGate supports TRON, BSC, and SOL stablecoin collection and payout with custody wallets, dedicated addresses, imported wallets, API callbacks, and payer address risk alerts.
Use Cases
Best-fit business scenarios
Dedicated addresses, callbacks, and wallet operations are designed around these high-frequency use cases.
Member top-up / balance recharge
Bind long-term deposit addresses to members, agents, or users. Incoming transfers can generate records and trigger callbacks for account crediting.
Games and digital content
Handle frequent small top-ups, item purchases, and automated delivery by connecting successful payment callbacks to your fulfillment flow.
Cross-border commerce and digital business
Process collections, payouts, and sweeps in one stablecoin workflow to reduce cross-border payment and fund management friction.
Workflow
One system for the full merchant stablecoin workflow
Designed around custody wallets, dedicated addresses, collection APIs, payout APIs, and risk alerts so teams can launch stablecoin capabilities faster.
Custody wallet generation
UUGate can generate hosted stablecoin wallets so merchants do not need to build wallet infrastructure first.
Dedicated address binding
Bind addresses to merchants, users, or business objects for long-term top-up and member recharge scenarios.
Collection API and callbacks
Use standardized order creation and callback flows for balance crediting, fulfillment, and activation.
Payout API and fund sweeps
Initiate payouts and sweeps by API so collection, payout, and fund operations stay in one platform.
Imported wallet monitoring
Import existing merchant wallet addresses for monitoring and collection recognition without changing ownership.
Payer address risk alerts
Identify and flag risky payer addresses earlier so operations teams can review suspicious deposits.

FAQ
Common questions before integration
Short answers about supported routes, wallet models, APIs, and risk alerts.
Which networks and assets are supported now?
The current core routes are TRON-USDT, BSC-USDT, BSC-USDC, and SOL-USDC for stablecoin collection and payout.
How do custody wallets, dedicated addresses, and imported wallets differ?
Custody wallets are generated and managed by UUGate. Dedicated addresses bind long term to members or business objects. Imported wallets connect existing merchant addresses for monitoring and recognition.
Can I integrate only the API and ignore wallet details?
Yes. You can use hosted wallets and standard APIs for collection, payout, and callbacks without building low-level wallet infrastructure.
Which mode fits member top-up or long-term recharge?
Dedicated addresses are usually better. A member can keep the same address, and incoming deposits trigger recognition and callbacks.
Do payouts and auto sweeps exist?
Yes. UUGate supports API payouts, fund sweeps, and wallet operations. Payout and sweep service fees are currently waived; only on-chain network fees apply.
What do payer address risk alerts do?
They help flag unusual payer addresses early so operations teams can review suspicious deposits and risky funding sources.
