# Tracer asset field contract

> Tracer documentation now uses asset instead of currency in limit and validation requests.

<Badge stroke icon="calendar-days" iconType="regular">August 21, 2026</Badge> <Badge stroke icon="file-code" iconType="regular">Documentation correction</Badge> <Badge color="red" size="lg" stroke icon="triangle-exclamation" iconType="regular">Action required</Badge>

## Affects

***

Teams that create Tracer limits or validations, write Tracer rules, or maintain Tracer client models.

## What changed

***

Tracer uses `asset`, not the retired `currency` field, in limit and validation request contracts, rule inputs, returned validation context, and Console terminology.

This is a documentation correction of the implemented contract. It does not announce a runtime release.

## Impact

***

**Classification: Action required.** Payload builders, rules, and client models that still use `currency` can send an unsupported contract.

## What you need to do

***

<Steps>
  <Step>Replace `currency` with `asset` in Tracer limit and validation integrations.</Step>
  <Step>Review rules, validation consumers, and client models before the next integration deployment.</Step>
</Steps>

### Deadline

Complete the review before the next Tracer integration deployment.
