Building the execution layer for agentic finance

AI Agents Can Think.
Web5 Nexus Helps Them Execute.

Financial execution infrastructure for AI agents and crypto applications. Request, authorize, execute, and verify controlled financial actions through one developer interface.

The problem

AI Is Moving Fast. Crypto Execution Is Still Fragmented.

AI agents are becoming capable of performing increasingly complex tasks. But when those tasks involve blockchain transactions, developers still need to integrate multiple independent infrastructure providers.

Fragmented Infrastructure

Separate providers for wallets, blockchain access, liquidity and transaction services.

Complex Execution

Developers must coordinate quotes, routes, authorization, submission and transaction monitoring.

Security & Permissions

Agents need controlled access to financial operations rather than unrestricted transaction authority.

Unreliable Workflows

Different APIs, providers and networks introduce integration complexity and failure points.

Web5 Nexus is building a unified infrastructure layer to simplify these workflows.

The solution

One Interface. Multiple Financial Actions.

Web5 Nexus coordinates controlled financial actions through one execution lifecycle. Swap and liquidity are live today via CrossDEX; additional action types are in development on the same path.

Live Swap

Token and liquidity execution via CrossDEX

In Development Transfer

Controlled asset movement between approved destinations

In Development Payment

Application and agent-driven payment workflows

Coming soon Treasury

Policy-bound automation for recurring financial operations

Same lifecycle for every action Request → Policy → Authorize → Execute → Notify → Verify
01 In Development

Quote & Route

Access supported blockchain transaction routes through a common interface.

02 Live

Swap & Liquidity

Connect to supported liquidity via CrossDEX - cross-chain, stablecoin, DEX, and tokenized securities stock.

03 In Development

Policy Guardrails

Configure permissions, spend limits, networks, recipients, and approved contracts before anything is signed.

04 In Development

Authorization

Route approved actions through a secure signing path. Private keys stay outside the AI model.

05 In Development

Notify & Verify

Track execution status, surface anomalies, and return structured receipts to the application.

Hover a capability to see how it serves the agent execution path.

How it works

From Agent Instruction to Onchain Execution.

Agents can decide. Web5 Nexus coordinates the controlled path from request to verified outcome.

Agent request

“Swap 100 USDC for ETH on an approved network, and do not exceed the configured spend limit.”

Hover assurance nodes: Audit prepares allowlists. Policy enforces them. Verify checks the outcome.

The agent or application submits a structured financial action. Reasoning stays with the agent. Execution starts here.

Two security layers. One execution path.

Avoid unsafe contracts

Audit contracts before agents interact. Feed approved lists into Policy.

Bound approved sessions

Spend limits, recipients, and elevated approval stop unbounded damage.

Keys stay off-model

Signing stays in approved wallet environments. The agent never holds authority alone.

Watch and verify

Notifications surface anomalies. Verify returns structured settlement outcomes.

Developer experience

Built for Developers. Designed for Agents.

Developer-friendly interfaces to integrate blockchain financial capabilities into applications and AI agent workflows.

In Development

REST APIs

A common interface for supported blockchain financial actions - planned as the agent-facing execution surface.

In Development

MCP Integration

A planned integration path for compatible AI agents to discover and invoke supported Web5 Nexus tools.

Live

SDKs

Auth Modal, ChainRouter, Bitcoin Core, and Web5js libraries on docs.web5.nexus under @web5nexus.

Product ecosystem

The Rails Behind Controlled Execution.

Live products and planned surfaces that connect into the agent execution path - connect, access, move value, assure contracts, and notify on outcomes.

Hover a rail to see how products support the execution path.

Connect & authorize

Social Login & Wallets

Live

Auth Modal social login and wallet sessions for approved signing flows.

Open docs

dApp Connect API & SDK

Coming soon

A single connect surface for wallets and sessions into the execution layer.

Smart Wallet Integrations

In Development

Deeper smart-wallet and scoped session surfaces for agent and app authorization.

Access & move value

ChainRouter

Live

One EVM RPC URL with automatic failover for wallets and dApps.

Launch ChainRouter

Crosschain DEX & API

Live

CrossDEX - cross-chain, stablecoin, DEX, and tokenized securities stock.

Launch CrossDEX

Fiat On/Off Ramp

Live

Funding rail into and out of supported onchain workflows.

Launch Ramp

Payment Gateway

Coming soon

Payment-style execution across supported chains through the same controlled path.

Assure & observe

Web5 Security Audit

Live

Pre-execution assurance: scan contracts before agents interact. Findings can feed policy allowlists - separate from post-execution verify.

Launch Audit

Notification Service

Coming soon

Runtime observation: transaction status, security signals, and product alerts when execution state changes.

Use cases

Powering the Next Generation of Financial Applications.

Built for teams that need controlled financial execution - with policy, authorization, assurance, and notifications in the path, not bolted on later.

Who builds with Web5 Nexus

AI agent platforms

Agent & copilot teams

Agents propose swaps, transfers, or payments. Policy, scoped signing, and verify keep authority bounded.

Wallets & crypto apps

Wallet & application builders

Ship financial actions with shared routing, resilient access, and clearer receipts - without stitching every provider.

Fintech & treasury

Fintech, payments & ops

Stablecoin movement, settlement, and rule-based operations with spend limits, allowlists, and status alerts.

What they execute

Live rail · CrossDEX

Controlled token swaps

Request a swap, enforce asset and spend limits, optionally require approved contracts, then return a verified outcome.

In development

Stablecoin transfers

Move funds to allowlisted destinations with deterministic policy checks and notify on status changes.

In development

Policy-bound payments

Payment-style actions through authorize → execute → notify → verify, with elevated approval for higher risk.

Coming soon

Treasury automation

Recurring or rule-based operations where guardrails - not open-ended agent authority - define what can run.

In development

Wallet-native financial actions

Expose swaps and transfers in-wallet with scoped sessions, shared policy semantics, and structured receipts.

Coming soon

Cross-app settlement

Apps request settlement through Nexus while users sign in approved environments and operators get outcome alerts.

Vision

The Financial Execution Layer for Agents and Applications.

Make blockchain financial execution accessible, reliable, and secure - so developers and AI agents can request, authorize, execute, and verify financial actions through one infrastructure layer.

Web5 Nexus is not a chatbot, a new chain, or a custodial wallet. It is the execution infrastructure between software that decides and blockchains that settle.
