Platform / Trader apps, APIs and integration

Four ways to put event contracts in front of your traders.

Take the hosted app, embed widgets in the surface you already have, ship the mobile SDK inside your app, or build against FIX and REST yourself. Most operators use two of the four.

The trader terminal, out of the box.

Watchlist, chart, book, ticket and positions, restyled per tenant, on desktop and in the mobile app. This is the default skin.

ORDER TICKET

Simulated data. Layout and fields as shipped.

The APIs

Three protocols, chosen by what you are building, not by plan tier.

Nothing here is gated behind a plan. Select a protocol to see what it covers and a representative call.

{{ protoTitle }}

{{ protoTag }}

{{ protoBody }}

·{{ it }}
{{ protoFile }} Sandbox 
{{ protoCode }}
Two timelines

Bolt-on or full integration. Any vendor quoting one number has not asked about your ledger.

Both tracks share the same five integration points. What differs is how much of your stack they touch, and therefore who has to be in the room.

Widgets

Three embeddable surfaces, styled from your tokens.

Colour, radius, type and density come from a token file you control, so the widget looks like your product rather than ours. No iframe styling fights.

Two timelines

Bolt-on or full integration. Any vendor quoting one number has not asked about your ledger.

Both tracks share the same five integration points. What differs is how much of your stack they touch, and therefore who has to be in the room.

Bolt-on

6 to 8 weeks

A tab or rail against your existing KYC, wallet and CRM, using our widgets and hosted app.

WK 0-2
Scoping, sandbox credentials, token file
WK 2-5
Widget placement and KYC status wiring
WK 5-7
CRM webhooks and reporting
WK 7-8
Quote coverage agreed, launch
Who you need

One frontend engineer, your KYC owner, and whoever runs your CRM. No ledger work.

Full integration

16 to 20 weeks

Event contracts on your primary trading surface, sharing ledger, balances and reporting.

WK 0-4
Scoping and ledger mapping
WK 4-12
FIX and REST build, UAT against sandbox
WK 12-16
Surveillance and reporting sign-off
WK 16-20
Pilot cohort, then full launch
Who you need

Backend and ledger owners, compliance, surveillance, plus a project lead. This is a programme, not a task.

Point 01
KYC and age gating

We consume your provider’s status. It stays the system of record.

Point 02
Ledger and balances

Your ledger stays authoritative. We reconcile to it daily.

Point 03
CRM lifecycle events

Webhooks for the five lifecycle stages, into your existing CRM.

Point 04
Regulatory reporting

Extracts in the formats your reporting obligations require.

Point 05
Market data

WebSocket in, or a push feed to your own distribution.

Widgets

Three embeddable surfaces, styled from your tokens.

Colour, radius, type and density come from a token file you control, so the widget looks like your product rather than ours. No iframe styling fights.

Market page Full category browse
Single contract One market, order entry
Category rail Horizontal, for a home screen
