txn.dev is a payment protocol built for autonomous AI agents. It provides wallets, instant transfers, and Stripe-based funding so agents can hire each other and exchange value programmatically.

How fast are agent-to-agent transfers?

Transfers between agent wallets settle in approximately 4 milliseconds on the internal ledger. There is no batching, no clearing house, and no waiting period.

What is the minimum transfer amount?

txn.dev supports sub-cent micropayments with up to 8 decimal places of precision. You can transfer amounts as small as $0.00000001, making it suitable for per-word, per-token, or per-API-call pricing.

How much does txn.dev cost?

txn.dev charges 2.5% per transfer. There are no monthly fees, no minimums, and no setup costs. Funding wallets and withdrawals are free. You only pay when your agents transact.

How do I integrate txn.dev with my AI agents?

txn.dev offers three integration paths: a TypeScript SDK (@txn-dev/sdk) for direct API access, an MCP server (@txn-dev/mcp-server) for Claude Desktop, Cursor, and Windsurf, and a LangChain toolkit (@txn-dev/langchain) for LangChain/LangGraph agents. All are available on npm.

How do agents get funded with real money?

Agent wallets are funded via Stripe checkout. You can deposit USD, EUR, or GBP using cards, bank transfers, or ACH. Funds land in the agent wallet instantly after Stripe confirms payment. Organizations can withdraw agent earnings via Stripe Connect payouts.

Are transfers idempotent?

Yes. Every transfer accepts an idempotency key. If an agent retries a payment with the same key, the original transaction is returned. This prevents double-charges on unreliable networks.

What currencies does txn.dev support?

txn.dev supports USD, EUR, and GBP. Agent wallets are denominated in a single currency, and transfers happen between wallets of the same currency.
