userId: "user_123",
type: "non-custodial", // or "custodial"
chains: ["base", "polygon"],
});

console.log(wallet.address);Built for Base, works everywhere
Onchain Banking Isn't Missing Protocols
It's missing a mobile interaction layer. We connect the fragmented world of blockchain protocols with the polished user experience of modern mobile apps.
Embedded Wallets
Create wallets directly inside mobile apps — custodial or non-custodial. Provision users instantly, manage keys securely, and support stablecoin-first flows without sending users to external wallets.
Mobile Execution Surfaces
Execute onchain actions where mobile intent already happens. Bring signing, approvals, and payments into native UI components — including keyboards and in-app surfaces — without breaking user flow.
Transaction Orchestration
Sponsor gas, route transactions, and automate onchain logic. Abstract chain complexity, manage execution policies, and coordinate multi-step transactions through a single API.
Yield & Capital Management
Put idle stablecoins to work — safely and programmatically. Integrate partner-managed lending vaults and yield strategies with transparent controls and explicit user opt-in.
FabricBloc is the bridge that makes money programmable and usable in your hand.
Everything You Need to Build

API + Indexing
Real-time data access for balances, history, and transaction status.
Interaction SDKs
Native components for keyboards, sheets, and in-app payment surfaces.
Launch NFT Collections
Deploy and manage NFT collections with built-in minting, metadata, and marketplace integration.

Designed From First Principles
FabricBloc's security model prioritizes user control, explicit consent, and minimal data collection. Built for enterprise partners who need to bring their own compliance stack.
Non-custodial by default
Users retain control of their wallets. FabricBloc supports key sharding and non-custodial architectures that avoid centralized custody.
Flexible custody models
Support custodial, non-custodial, and hybrid designs so partners can bring their own compliance and regulatory stack.
Secure execution environments
Sensitive signing and key operations are isolated to reduce attack surface across mobile and backend systems.
Explicit user intent
All onchain actions require deliberate user approval. No background signing or hidden execution.
Privacy-first by design
No keylogging, no behavioral tracking, and minimal data retention. Wallet addresses act as the primary identifier.
Auditability & verification
Architecture designed to support logging, audits, and independent security review.
Authentication
Onboard users faster with familiar login methods — OAuth, passkeys, Sign in with Apple, Google, and more.
Analytics & Insights
Monitor wallet activity, transaction flows, and onchain behavior in real time without relying on PII.
