Brand

The mark is a container, and the payment is inside it.

An orthogonal, stepped W with round joins. The square nested in its centre cavity is the held value sitting inside the warrant, and it is the only element that is ever a colour other than the mark’s own.

The four states

The square carries the state and nothing else does. The three signal colours are product states, not decoration: if no warrant is in that state, the colour does not appear.

• Default

  Nav, footer, favicon at rest.

• Held

  Funds parked, waiting on the verifier.

• Released

  Deliverable matched the spec.

• Escalated

  A human has to decide.

Clear space and minimum size

Clear space on all four sides equals the square: 11 units of the mark’s 120-unit box. Minimum size is 20px. Below 24px keep the square and drop any surrounding container. Never place the mark on a surface that is not bone, paper or char, and never apply a gradient to it.

Palette

Every value is declared once, in tokens.css. Nothing in the product writes a hex.

Using the mark

You may use the Warrant mark and wordmark to refer to Warrant: in an article, a talk, an integration listing, or a “works with” badge. You may not use them as your own product’s mark, in a way that implies we endorse or built your product, or modified — recoloured, redrawn, stretched, or with the square replaced.
