Control plane
Three experiences. One trust layer.
Designed with premium product storytelling: every layer appears with context, motion and hierarchy. Users understand Signiqo is not just a wallet, but financial infrastructure.
The human stays in control
Biometrics, limits and clear approvals before any spending is delegated.
The agent works with a budget
It can consume x402 APIs without receiving raw signing permissions.
The merchant gets paid without complex billing
HTTP 402, verifiable proof, settlement and audit trails.
Biometric wallet
Simple self-custody for real people.
The human experience stays at the center: signing in, creating an account, receiving and sending assets should feel as clear as a banking app, but with Web3 self-custody.
No seed phrases
The account is protected with device passkeys and controlled recovery, not fragile phrases.
Biometric sign-in
Face ID, Touch ID or Windows Hello as step-up for sensitive actions and new permissions.
Controlled multichain access
The wallet keeps a curated network and asset catalog, with validations before funds move.
Signiqo Meridian
x402 payments for a web where agents can buy too.
Meridian turns programmable payment into a governed experience: budgets, domains, merchants, tokens, limits, audit trails, proofs and idempotency before a single cent moves.
An API, dataset, MCP server, article or inference endpoint.
Signiqo validates domain, amount, token, recipient and expiration.
Only when the human-approved policy allows that spend.
The merchant verifies the proof and releases access.
Financial control
Policy engine
Autonomous budgets without losing control.
Active limit for Research Agent.
Only verified or intentionally limited providers.
Scope
x402:pay
Allowed through policy

Idempotency key
Blocks duplicate charges

High-value payment or new domain
Production security
It is not just paying with crypto: it is governing who can pay, how much and to whom.
Meridian never gives raw signatures to third parties. Every payment is bound to user, agent, merchant, domain, resource, amount, token, network, recipient, expiration and nonce.
For developers and merchants
Monetize APIs, content, data and inference without building billing from scratch.
Third parties can publish resources, register domains, receive settlement and use the SDK to respond with HTTP 402 requirements compatible with Signiqo.

);A wallet for humans. A payment rail for agents.
The same identity that protects the user can enable agents with budgets, limits, approvals and audit trails.
