PAYMENT INFRASTRUCTURE

Instant Micro-Clearing Rails.

Settle micro-transactions for APIs, AI agent compute, and digital commerce in sub-milliseconds with zero gas friction.

The Standard for Machine-to-Machine Payments

Traditional credit card payment rails impose a $0.30 fixed fee per transaction, rendering micro-payments and autonomous agent loops mathematically impossible. Legacy blockchain transactions suffer from high gas fees, variable latency, and disruptive wallet signature prompts.

Corbel implements the x402 protocol specification over attested hardware enclaves. Clients authorize payments with cryptographic signatures (such as gasless cryptographic permits or high-throughput payment channels), which are verified and cleared instantaneously by enclave silicon with zero gas burden on the end user.

LIVE PROTOCOL SIMULATOR

Sub-Millisecond M2M Clearing in Action

Watch an autonomous AI agent issue an x402-authorized request to procure a real-time data feed. The Intel TDX enclave clears the micro-transaction off-chain in 1.1ms and returns a verified cryptographic receipt.

AUTONOMOUS ECONOMY

Cryptographic Spending Envelopes for Agent Fleets

Enterprises dispatch fleets of autonomous agents to execute research, procure API services, and settle programmatic transactions. Corbel allows operators to issue verifiable spending envelopes enforced by hardware attestation—ensuring agents can never overspend or deviate from authorization boundaries.

✔ Granular per-request and per-hour budget limits
✔ Instant off-chain cryptographic signature verification
✔ Zero wallet prompts or interactive approval delays
