| Core Architectural Layer |
Agentic Micro-Payment OS & Settlement Engine (Solana-native, Sub-PDA bounded) |
Smart contract wallet SDK for AI agents on Base/Ethereum (x402 enabled) |
B2B custodial payment API wrapping USDC on Base/Polygon |
Centralized fiat payment gateway & acquiring network designed for human checkouts |
| Latency & Settlement Profile |
Hybrid: In-Memory Netting ~0.14ms | Solana Block ~400ms (Optimistic confirmation) |
On-chain Base block: ~2s soft confirmation (L1 finality ~15 mins) |
API round-trip: 1 - 3s + EVM batch settlement confirmation |
2 - 3 business days (T+2 banking interchange clearing & batch settlement) |
| Transaction Cost & Granularity |
Sub-cent viable (< $0.0002 on-chain, fraction of nano-cent via netting). Native $0.0001 per call |
~$0.001 - $0.005 Base gas fee (Post-Dencun L2 blobs; requires batching for micro-streams) |
$0.01 - $0.05+ per payment call API markup; corporate batch invoicing |
$0.30 fixed swipe fee + 2.9% (30,000% overhead on a $0.001 API query) |
| Agent Threat Model & Blast Radius |
Blast-Radius Containment: Sub-PDA programmatic spending bounds + Instant Panic Kill-Switch |
Application-level MPC key policies; vulnerable to bounded drain if agent logic is tricked |
Centralized SaaS quota limits managed on corporate web console |
Post-loss remediation: Must freeze corporate card & file dispute taking 30-60 days |
| Integration & User Experience |
Invisible Web3: Biometric Passkey, instant fiat onramp & native Model Context Protocol (MCP) |
Developer CDP API keys, wallet management SDKs, EVM contract infrastructure |
Web2 enterprise API keys linked to corporate deposit accounts |
Manual credit card checkout forms, exposed PII, subject to payment fraud |
| Custody & Trust Model |
Non-Custodial: Smart contract state invariants on Solana; real yield protocol fee utility |
Non-Custodial / Hybrid: User-held MPC keys; zero native token (Base sequencer value) |
Custodial: Funds deposited in corporate account; closed-source margin capture |
Fully Custodial: Banking rails & card network escrow with centralized fund withholding |
| Human-in-the-Loop & Escalation |
Native Reverse x402: Sub-second programmatic escrow dispatch with async human verification SLA |
No native bounty rail; developers must manually architect custom escalation webhooks |
Enterprise support tickets and manual customer service intervention queues |
30 - 90 day credit card chargeback arbitration with strict dispute penalties |
| Ecosystem Maturity & Fiat Rails |
Emerging Specialist: Purpose-built for high-throughput autonomous agent micro-economies |
High: Deep EVM ecosystem, extensive developer tooling & native Coinbase fiat ramps |
Moderate: Expanding enterprise B2B partner network & vendor agent integrations |
Global Dominance: Trillions in annual volume across 135+ currencies and banking rails |
