Built on Solana

Transparent on-chain banking

Every transaction verifiable on Solana blockchain. Sub-second finality with 150ms confirmations, sub-cent transaction costs, and institutional-grade infrastructure. Complete transparency for agent operations.

  • 150ms finality with Alpenglow consensus protocol
  • Average $0.017 transaction fee, median $0.0011
  • Immutable audit trail and cryptographic proof of operations

Native Machine Payments Protocol integration

Built on Stripe's MPP standard for autonomous machine-to-machine payments. AI agents can request resources, authorize transactions, and receive delivery. All without human intervention.

Request, authorize, deliver

MPP enables autonomous payment flows: agents request resources, services respond with payment terms, agents authorize transactions, and resources are delivered. All settled transparently on Solana.

Protocol-enforced spending controls

Smart contracts enforce spending policies directly at the protocol level. Configure limits, allowlists, and time-bound permissions that execute autonomously, all validated on-chain before settlement.

  • Cryptographic agent identities and spending limits
  • Multi-signature authorization and hierarchical accounts
  • Programmable compliance and fraud detection

How MPPFi works

Machine Payments Protocol enables fully autonomous machine-to-machine payments through a four-phase flow

1

Discovery & Request

Agent discovers service endpoint, sends HTTP POST with MPP content-type header containing resource URI and requirements. Service validates request schema.

Service discovery via .well-known
Structured MPP request payload
Resource specification & parameters
2

Terms Negotiation

Service responds with 402 Payment Required, including pricing structure, accepted payment methods (USDC/SOL), and authorization requirements in JSON schema.

HTTP 402 with payment terms
Multi-token pricing options
Smart contract address for settlement
3

Authorization & Payment

Agent evaluates terms against policy constraints, signs transaction with private key, executes Solana program to transfer funds. 150ms finality with cryptographic proof.

Policy-enforced authorization
Ed25519 signature with keypair
On-chain settlement in 150ms
4

Delivery & Settlement

Service validates transaction on-chain, delivers resource via HTTP 200 response. Complete audit trail recorded: transaction hash, block height, timestamps, signatures.

On-chain payment verification
Atomic resource delivery
Immutable transaction receipt
