Core Flow

From agent intent to settled transaction.

02IntelligenceBeta

Know who your agent is sending to before it sends.

Every outbound transfer runs through 7-signal counterparty risk scoring. Sanctioned addresses, mixer exposure, stolen-fund flags — evaluated before signing.

What's inside

Everything your agent needs to transact on-chain.

01

MCP Server

One protocol for every blockchain operation

Connect any AI agent to on-chain operations via standard MCP protocol
Security bands control what each agent can access
LangChain, CrewAI, Pydantic AI, Claude Agent SDK, or custom MCP runtimes
Standard protocol for AI agents to transact on-chain

Wallet Actions

Query, prepare, and execute in one tool call

Balances, prices, fee quotes, asset resolution, tx history
Prepare unsigned transfers with signing-ready transaction hex
Resolve tokens by symbol or name across supported chains
Returns wallet-ready transaction payloads

Non-custodial signing

MPC by default. OWS for teams that need keys on their servers.

2-of-2 MPC default — neither WalletSuite nor your team can sign alone
Self-hosted OWS opt-out for HFT and regulated environments
Spending policies with chain and time restrictions in both paths
Non-custodial by architecture

Why WalletSuite?

Band-based access control

Read/prepare/sign/broadcast hierarchy. Agents can’t see destructive tools unless operators opt in.

Structured error taxonomy

6 error categories with structured recovery guidance. The agent knows whether to retry, fix input, or escalate to the user.

Pre-sign policy evaluation

Spend limits, chain allowlists, and daily caps checked before every signing.

Key isolation

Private keys never enter LLM context. Default 2-of-2 MPC means no single party — including WalletSuite — can sign alone. OWS opt-out keeps keys fully on your infrastructure, AES-256-GCM encrypted at rest.

Persistent audit trail

Every decision logged with policy evaluation and approval status. Compliance-ready from day one.

x402 economyBeta

Agents pay for API calls and monetize their own tools with x402 micropayments. Built-in client and server.

Any LLM, any chain

MCP-compatible. LangChain, CrewAI, Pydantic AI, Claude Agent SDK, custom runtimes. 80+ chains for read and prepare. Ethereum + Tron live for OWS signing today; chain coverage expanding with MPC GA.

Runtime validation

Zod validates every backend response before it reaches the LLM. No silent corruption.

Signing

Two signing modes

Policy gates every signature in both modes — MPC default or OWS opt-out. You decide the level of agent autonomy.

Owner Mode

You review and confirm every transaction

Create wallets, define policies, delegate keys to agents
Every signing and broadcast requires your explicit approval
Policies define allowed chains and expiration windows

Agent Mode

Autonomous signing within the policy you defined

Scoped token signing, no passphrase needed
Restricted to allowed chains and the policy time window
Tokens expire with the policy and can be revoked anytime

Owner Mode

Owner mode — you drive every step via natural language. Create, fund, transfer, and verify, with full visibility into each tool call.
