A guide to building agentic apps on Privy
Everything you need to equip agents with wallets, funding, and payments

Today, more than a third of new developers on Privy are building agentic use cases. Over the past few months, we’ve focused on making it easy to equip agents with wallets, while ensuring they operate safely within programmable, human-defined guardrails.
As agents become first-class actors, APIs alone aren’t enough. They need accounts, funding, and the ability to transact autonomously.
This guide brings together the core building blocks for agentic apps on Privy, from provisioning wallets to enabling real-world payments and data access, so you can go from idea to production faster.
1. Start here: Give your agent a wallet and fund it
Before an agent can act, it needs an identity and a balance.
On Privy, this starts with embedded wallets that can be created, funded, and managed programmatically. Agents don’t have to rely on external infrastructure or user-managed keys. Instead, they operate with their own accounts, directly within your application.
With the Agent CLI and sandbox, you can:
Spin up wallets for agents in seconds
Fund and manage balances
Monitor activity through a human-facing interface
For more advanced workflows, wallets can be provisioned directly into agent frameworks like OpenClaw, allowing agents to operate with their own accounts from the moment they’re instantiated.

2. Define how your agent can act
Once your agent is funded, it is important to set policies to determine how they are allowed to act. Without controls, agents are either too risky to deploy or too constrained to be useful. The goal is to give them autonomy within clearly defined boundaries.
Using Privy’s policy engine, you can enforce policies at the wallet layer for your agent.
Common policy constraints include:
Transfer limits to set maximum amounts per transaction or within defined time windows
Allowlisted contracts to restrict interactions to approved protocols or contracts
Recipient restrictions to limit where funds can be sent
Time-based controls to define when agents are allowed to operate
Action-specific rules to constrain parameters for swaps, trades, or other onchain operations
These controls can be combined to reflect real-world workflows, from simple spending limits to more complex, multi-step approval systems.
By defining how money is allowed to move, you get agents that can operate independently, while staying within programmable, human-defined guardrails.

3. Enable payments: Let agents transact
Once agents are equipped with wallets, it becomes possible for them to both pay and get paid. Different use cases require different payment patterns. Privy supports multiple approaches, depending on how your agents interact with the world.
HTTP-native payments (x402)
For request-based interactions, x402 allows agents to attach payments directly to API calls.
Pay per request
Fully onchain
Simple and composable for agent-to-service interactions
Session-based payments (MPP)
For higher-frequency interactions, the Machine Payments Protocol (MPP) introduces session-based payments.
Offchain payment sessions with periodic settlement
Lower overhead for repeated interactions
Designed for real-time, agent-driven systems
Real-world payments (Stripe)
For bridging into traditional systems, Stripe extends x402 into its global merchant network, enabling agents to transact with existing businesses.
Accept machine-native payments through Stripe
Support real-world purchases and payouts
Seamless movement between stablecoins and fiat systems
Across all three, the pattern is consistent: payments become part of the request itself.

4. Pay for data and services
With a wallet, agents can also unlock services. They can pay for API access, unlock datasets on demand, and do so programmatically.
For example, combining Allium data with x402 allows agents to pay per query for blockchain data, turning data access into a metered, programmable service.
We’re already seeing developers experiment with this model:
AI trading agents that execute and settle autonomously
Arbitrage systems spun up in minutes
Tools that track and analyze onchain activity across networks
The common thread is that identity, payments, and data access no longer require separate human workflows. They’re unified, programmable, and embedded directly into how agents operate.

5. Putting it together: The agent stack
These building blocks come together into a simple, composable system:
Give your agent a wallet and fund it: Create wallets with the Agent CLI or within your agent framework, and provision balances for it to operate.
Define how your agent can act: Apply policies to enforce limits, permissions, and guardrails at the wallet layer.
Enable payments: Choose the right pattern for your use case, from per-request payments with x402 to session-based flows with MPP and real-world transactions via Stripe.
Pay for data and services: Use those payment primitives to access APIs, datasets, and services programmatically.
Each layer builds on the one before it. Together, they turn agents into fully capable economic actors that can hold funds, make decisions, and take action in the real world.
Privy remains focused on making it easier to equip agents with wallets, funding, and the ability to transact safely. We are excited to continue working closely with agentic builders and see what you create next. If you have feedback with us, do reach out at privy.io/slack or at support@privy.io.
