Capabilities

Everything wallets need to do.

Embedded creation

No redirects. No modals. Wallets live in your UI — native to your app experience.

Hardware-backed keys

Secure Enclave on iOS. TEE on Android. Keys are generated on-device and never exported.

Gas sponsorship

Pay user fees on their behalf. Set per-wallet caps and policy rules in the console.

All EVM

Base, Polygon, and Sepolia today. More EVM networks coming via the roadmap.

Recovery options

Social, MPC, or biometric recovery. You choose the model that fits your UX.

Auditable activity

Real-time balances, full transaction history, and throughput metrics — no external pipeline.

How it works

Three steps. Zero blockchain expertise required.

Get your key

Sign in to console. Create a project. Copy your secret key.
Install SDK

TypeScript and Python SDKs for server workflows. FabricKit for iOS and Android. REST and MCP stay available for direct API and agent integrations.
Create wallet

fb.wallets.create({ userId }) — the wallet is created. You're done.

FAQ · structured for voice & AI search

Common questions.

What is a FabricBloc wallet?

A non-custodial Ethereum-compatible wallet created inside your app. Keys are hardware-backed and never leave the user's device.

How is FabricBloc different from Magic or Privy?

FabricBloc isn't auth-only. It bundles wallets, tokens, NFTs, vaults, RPC, analytics, and an MCP server for AI agents — under one API key.

Which chains are supported?

EVM-only today: Base, Polygon, and Sepolia testnet. More EVM networks are on the roadmap.

What does it cost?

Free tier covers prototyping and small workloads. PRO unlocks paid quotas and priority support; see the pricing page for current tiers. Enterprise adds white-label and custom contracting.

Can my AI agent use it?

Yes. Install our MCP server and any Claude or Codex agent can read balances, sign transactions, and orchestrate vaults with scoped permissions.
