ZettaPay is a Solana-native payment protocol designed for the agentic economy. 0.30% fees, sub-2-second settlement, no wallet connect, no custody. Built so machines and humans can transact without the legacy tax of credit-card rails.
Stripe's 2.9% + $0.30 makes a $0.05 LLM call economically impossible. Credit-card chargebacks assume a human in the loop. Issuing API keys to autonomous code without spend boundaries is a catastrophic risk waiting to happen. Every team building agent-driven SaaS reinvents the same broken plumbing.
ZettaPay is a thin, non-custodial layer over Solana USDC. We never hold funds. We don't
require wallet connections. We expose x402
and MCP as first-class citizens so any agent
framework can integrate in minutes. The spec and SDKs are MIT.
The constraints that define the protocol — not preferences, but hard rules.
Merchants paste a public address at signup. Payers scan a QR or copy an address. No wallet connect, no browser-extension dependency, no signature prompt sitting in front of checkout.
Funds move directly from payer to merchant on-chain. We are not a money services business. The protocol owns no float, no escrow, no settlement pool.
HMAC-signed webhooks with idempotency keys, exponential retries, replay from dashboard, structured logs with correlation IDs. We hold ourselves to the bar humans pay 2.9% for.
x402 and MCP are first-class. The protocol assumes the payer might be a Claude tool call, a GPT operator, or a Gemini agent — not just a human with a card.
Protocol spec and SDKs are MIT. Auditable static analysis on every on-chain commit. Public status page. Bug bounty before scale. The moat is adoption, not lock-in.
Paste a wallet. Drop a script tag. Start accepting USDC.
