Lintel

Lintel lets banks and fintechs settle dollars and euros onchain in 0.4 seconds, with compliance written into the protocol. It needed a site that a bank’s treasury team would trust and a developer would bookmark.

The brief: explain settlement finality without jargon, prove the speed, and send two very different audiences, developers and treasury desks, to the right door.

A lintel is the stone beam that carries the load across an opening. The name became the whole idea: Lintel carries money across the gap between banks and blockchains.

The hero is a live Three.js scene: two stone piers and a lintel drop course by course and lock into place, and cobalt light, the transactions, streams through the opening. Scrolling walks the camera toward the gate.

Everything else is built from the same material: basalt and limestone greys, slabs that settle as you reach them, and cobalt only where value moves. The type is Archivo at its widest for display, so headlines read like inscriptions.

One invoice from Lisbon to Mexico City, sent at 17:01 on a Friday. As you scroll, the clock runs through the banking week, drawn to scale: the weekend fills most of the bar. On Lintel the same payment is final in 0.41 seconds.

Issuance, settlement and compliance as three stone courses that drop and settle in order, foundation first, each with the figures an engineer would ask for.

“Ship a payout in twelve lines”: the SDK in TypeScript, Go and cURL, with a receipt that confirms the transfer as final in its block, just as the real API answers.

Payroll, treasury sweeps, card settlement, marketplaces and remittance, pinned and moving sideways as you scroll, each with the small piece of product UI it would show.

112 validators in 31 countries, one block each, grouped by region. Filter by banks, custodians, infrastructure or universities and the rest step back.

The close sends each audience its own way: testnet keys for developers, a call with the treasury desk for banks and fintechs.

On a phone the gate rises above the headline, the Friday timeline stacks into cards, and the code scrolls sideways inside its own window.
