Product layer for Web3 apps

Web5 Nexus

Stop spending months stitching Web3 vendors together.

dApp, wallet, and fintech teams usually juggle separate vendors for wallets, RPCs, swaps, and ramps. Open CrossDEX, Ramp, ChainRouter, and Audit today, then integrate from docs.

How the stack works

One route through the products you need

Scroll to follow a request from your app through Web5 Nexus. CrossDEX, Ramp, ChainRouter, and Audit are live; Auth Modal integrates from docs.

01

Your app starts the request

One user action enters through your existing product UI.

02

Auth Modal handles identity

Social login creates the wallet session from docs, without exposing Web3 complexity in your UI.

03

ChainRouter keeps RPC live

The same wallet URL moves to a healthy upstream when a node fails.

04

Products complete the job

CrossDEX swaps, Ramp checkout, and Audit checks connect to the same product flow.

The challenge

The Web3 toolchain is fragmented

A typical stack wires WalletConnect, RPC providers, indexers, swap APIs, and fiat rails. Each brings its own SDK, keys, and billing. Features wait while custom integrations pile up.

The result: launches stall while integrations pile up

Launches slip, UX feels unreliable, and Web2 teams treat Web3 as too expensive to finish.

The solution

Live products for the layers you need now

Web5 Nexus is the product layer teams use instead of stitching vendors: swaps, fiat, RPC, audit, and social auth docs. Open them live, then integrate.

Try the live apps

CrossDEX for swaps. Ramp for fiat. ChainRouter for RPC failover. Audit for contract scans. No install required to evaluate.

Integrate from docs

Auth Modal, ChainRouter SDK, Bitcoin Core, and Web5js on docs.web5.nexus. Built for product and engineering teams.

Embed where you ship

Ramp partner studio, ChainRouter wallet RPC URLs, and Auth Modal social login. Add more toolkit pieces as they go live.

Live products

Replace custom integrations with apps you can open today

Built for dApp, wallet, and fintech teams. These are production URLs. Use them as-is or embed via docs and partner flows.

CrossDEX

Cross-chain and stablecoin swaps without bolting on a separate aggregator stack.

Live Launch

Ramp

Fiat buy and sell in-product. Widget and partner studio instead of a one-off MoonPay-only path.

Live Launch

ChainRouter

One EVM RPC URL with failover so wallets stop dying on a single public node.

Live Launch

Web5 Audit

Automated contract scans before you ship. Upload, scan, and review findings in one place.

                What problem does Web5 Nexus solve?
                
dApp, wallet, and fintech teams usually stitch separate vendors for wallets, RPC, swaps, fiat, and audits. That custom integration eats months. Web5 Nexus ships CrossDEX, Ramp, ChainRouter, Audit, and Auth Modal docs as a product layer you can open and integrate.

              

              

                Who is Web5 Nexus for?
                
Product and engineering teams shipping Web3 features inside apps. Buy live apps (swaps, fiat, RPC, audit) and SDKs under @web5nexus, not another dashboard to stitch by hand.

              

              

                What can I use today?
                
CrossDEX (swaps), Ramp (fiat), ChainRouter (EVM RPC failover), and Web5 Audit (contract scans) are live. Auth Modal, Bitcoin Core, Web5js, and address validation are in the docs. Everything else is Coming soon.

              

              

                Do I need deep blockchain expertise?
                
No. Evaluate the live apps in the browser first. When you integrate, follow docs.web5.nexus written for product and engineering teams.
