Steer your agents,
don’t trust them.
How Bridle looks and sounds. Use this page when you write about Bridle, build with it or draw next to it.
You set the limits once.
The contract enforces them.
You keep the veto.
01 / Essence
Bridle is the brand of steering.
It makes agent autonomy safe by putting a clear, checkable limit around what an agent can do.
What it is
A NEAR contract that lets an AI agent spend across chains without holding a key, inside a mandate the owner signs once.
Who it is for
Developers and teams who want agents to move money and need to cap the downside, and anyone who must grasp the idea in one glance.
The promise
You set the limits once, the contract enforces them, and you keep the veto.
What “Bridle” means
A bridle does not stop a horse. It lets the rider set the direction while the horse does the work. Here the agent does the work, and your rules set where it can go.
What the brand is not: hype, fear or cute. It avoids drain-and-rug language, horse clipart and anything that sounds like a promise of safety it cannot keep.
02 / Personality
Calm, exact, candid.
Calm
Reads as something under control, never alarmed.
Generous space, one accent colour, alert colours only when something needs attention.
Exact
Names the number, the rule and the limit.
Stablecoin amounts, plain-language rules, monospace type for values.
Candid
States its limits openly.
An honest-edges section, no overclaiming, a label on any simulated interface.
03 / Voice
A precise, unhurried colleague.
Bridle states the rule, names the limit and never raises its voice.
- 01
Say the rule, not the feeling.
“Up to $50 a day” beats “stay safe”.
- 02
Plain over clever.
Short sentences, under about 20 words. Favour the verbs that match the product: set, sign, propose, veto, revoke.
- 03
Be candid about limits.
If version one does not do something, say so. “Transfers only” is a feature of honesty.
- 04
Stay calm under attack.
When something is blocked, say what and why. No exclamation marks and no alarm words.

Bridle does not remove trust in the signing network, so any claim of “trustless” would contradict the product’s own limits. They are written out in the docs.

v1 limits: transfers only, stablecoin caps, one trust assumption.
Mechanics
- Sentence case everywhere, including buttons and headings.
- “Bridle” is always capitalised.
- Rules use whole dollars (“$50 a day”). Feed amounts show two decimals ($18.00).
- Values, addresses and amounts are set in monospace.
04 / Logo
One line, two rings.
The mark is a single vertical line with two rings: a bridle seen side on. It takes the colour of the text around it. Use the supplied files and do not redraw it.
With the wordmark
Set the name in Instrument Sans, semibold, with tight tracking. Always capitalised.
Small sizes
Use a heavier stroke as the mark gets small, so the rings stay open.
Signature
The mark and the name, locked together. Use one of these arrangements rather than building your own.
Horizontal on light, stacked on ink, horizontal on emerald.
Do
- Use ink, white or emerald, on a background that keeps the strokes clear.
- Leave space around the mark, at least the width of one ring.
- Keep the rings and line as drawn.
Do not
- Add a horse, a leash, reins or any other illustration.
- Stretch, rotate, outline or add effects to the mark.
- Place it over busy photography, or recolour it outside the palette.
05 / Colour
One accent. Alerts only when needed.
Mostly ink, paper and grey. Click any swatch to copy its value.
Core
Ink and paper do most of the work.
Neutrals
For hierarchy, borders and supporting text.
Accent and status
Emerald marks what is allowed or active. Red and amber appear only when something is blocked or waiting.
Dark theme
Keep the contrast between cards and the page.
Contrast, measured against WCAG: ink on paper 17.6:1, emerald on paper 4.8:1, emerald on white 5.2:1, mute on paper 5.6:1, and emerald-on-dark on ink 10.6:1. Do not rely on colour alone: every status also carries a word.
06 / Type
Instrument Sans for words. JetBrains Mono for values.

07 / Interface
The interface should feel governed.
Clear surfaces, deliberate spacing and explicit states. Each component says what is happening and what happens next.

Layout
- Align content to a consistent grid.
- Use whitespace to set hierarchy.
- Keep cards and borders quiet.
- Use rounded corners consistently, not decoratively.
States
- Show status as a word, not colour alone.
- Explain why a payment is blocked.
- Keep proposed, waiting and executed distinct.
- Keep errors calm and actionable.
08 / In use
Say what it does not do.
One character across product, docs and posts. Adapt the format, not the voice.
Website
Steer your agents,
don’t trust them.
You set the limits once. The contract enforces them.
Social and developer posts
Your AI agent doesn’t need your private key. It needs a bridle.
One idea per post. Be specific about what is live, what runs on a testnet and what is still planned.
The honest-edges rule
Never claim more than the product does. Say when something runs on a testnet, when a feature is planned and not built, and which trust assumptions remain. Anything that shows a simulated interface carries a label saying so.
Steer your agents,
don’t trust them.
