Chain-agnostic payment layer

Stop losing users at cross-chain checkout.
Turn any-chain stablecoins into real usage.

NuOrbit lets your users pay from whatever chain they already hold USDC / USDT on. You decide whether that payment triggers a cross-chain execution on a target chain, or comes back as a standard x402 payment proof your app can trust — while user funds stay on their source chain.

Cross-Chain Execution demoDirect Payment Proof demo
These demos run on testnets only. NuOrbit itself is designed to be chain-agnostic and production-ready.

Two products, two very different jobs.

NuOrbit exposes two clear lanes. One is built for protocols that need cross-chain execution. The other is built for apps that want a simple, verifiable payment receipt from any chain.

Cross-Chain Execution

Pay on one chain. Execute on another. Users pay with stablecoins on their home chain. NuOrbit’s server wallet executes your provider contract on a target chain and returns an x402 execution proof. Funds never leave the source chain.

Problem it solves
  • Protocols need contracts on other chains to move, but can’t afford to lose TVL or UX.
  • Users refuse to switch networks or manage gas for cross-chain actions.
  • Custom routers and gas-abstraction stacks are expensive and brittle to maintain.
Who it’s for
  • L1 / L2 chains that want TVL retention with cross-chain logic.
  • DeFi, restaking, and liquid staking protocols.
  • Cross-chain games, SocialFi, and AI / compute networks.
What it delivers
  • Source-chain payment, target-chain execution via NuOrbit server wallet.
  • Background settlement so users see a single, smooth checkout.
  • Standard x402 execution proof for every cross-chain action.

If another protocol gives users one-click cross-chain actions and you still ask them to juggle chains, they’ll win your flows.

Direct Payment Proof

Accept payments from any chain with one proof format. Users pay in USDC / USDT from whichever chain they already hold it on. NuOrbit verifies the payment and returns a standard x402 payment proof – your app decides what to unlock, on-chain or off-chain.

Problem it solves
  • Users’ stablecoins are scattered across chains – they won’t move funds just to pay you.
  • Per-chain payment logic and wallets are hard to manage and reconcile.
  • Most checkouts stop at “paid” with no reusable, verifiable receipt format.
Who it’s for
  • Web3 SaaS and subscription products.
  • AI / API platforms and infrastructure providers.
  • Gaming economies, marketplaces, and token-gated communities.
What it delivers
  • Any-chain USDC / USDT acceptance through a single integration.
  • Unified x402 payment proof you can treat as an invoice, receipt, or access token.
  • No target-chain contract required – works for both off-chain and on-chain services.

The first apps that feel chain-agnostic at checkout will own the highest-value users.

Where NuOrbit fits in the cross-chain stack.

Bridges and routers move assets. NuOrbit focuses on how those assets are used: executing contracts and producing verifiable payment and execution proofs that products can rely on.

Built for stablecoin flows.

NuOrbit is optimized for USDC / USDT-style assets and the flows around them – checkouts, on-chain actions, and cross-chain settlement – rather than general-purpose asset transport.

Works alongside bridges and routers.

You can keep your existing bridges and routing infra. NuOrbit sits on top as a payment and proof layer, giving users a cleaner experience and your systems a consistent receipt format.

Standardized proofs.

x402 proofs give infra teams, auditors, and integrators a common language for “this payment or execution really happened”, regardless of which chain the user started from.

Supported chains

NuOrbit is designed to be chain-agnostic. The demos use testnets only, but map onto the same patterns you’d run in production.

For developers

See the x402 checkout and registry under the hood.

The technical demo page walks through the exact flow this site uses: launching the NuOrbit checkout, routing stablecoin payments into the NuOrbit payment registry on GOAT Testnet3, and returning x402 proofs back to your app or mission control.

  • Understand how sessions, deposits, and proofs are wired together.
  • See the difference between Cross-Chain Execution and Direct Payment Proof at the x402 level.
  • Copy-paste SDK and popup launcher snippets into your own front-end.
