One API across Ethereum, Polygon, and BNB Chain
Merchants choose the chain that matches their treasury and on-ramp. Your integration stays the same — only the network field changes.
The challenge
Supporting three EVM stacks usually means three indexers, three gas wallets, and three ops runbooks.
The solution
NxtGateW abstracts networks behind the wallet API. Create on ethereum, polygon, or bsc and receive the same webhook shape.
How it works
- Choose network when creating the wallet (and match the asset your on-ramp sends).
- Display the deposit address; payer or Cash App rail funds it.
- Indexers watch that chain; split uses the matching gas wallet.
- Your backend treats events identically regardless of chain.
What you get
- USDC (Circle) on Ethereum / Polygon; USDT on BNB Chain.
- Single API key set for all networks.
- Sandbox paths available for testnets where documented.
