Applied to build this week.

Scope: Rust codec (WASM) + merchant MCP server. Claude drafts a crypto invoice, encodes it into a self-contained URL, sends it. Payer opens the link, pays P2P. No backend touched at any point.

The only invoice tool that works even if we shut
down.

[VoidPay @voidpay_xyz]

We built a crypto invoicing tool with zero backend.
No database. No signup. No server to store your
data.

Here's how creating and paying an invoice works —
and why the links keep working even if we shut
down. 🧵

What we trade for this:

• ~2KB URL cap (≈3 line items typical)
• No ERC-1271 / Safe multisig yet
• On-chain addresses stay pseudonymous —
not anonymous

No promises we can't keep. Privacy by architecture,
not policy.

VoidPay now runs on Base.

5 chains total: Ethereum, Base, Arbitrum, Optimism, Polygon.

Payment flow switched to typed viem errors — survives sped-up and replaced txs cleanly.

Still zero-backend. URL = invoice.
