Changelog

All notable changes to the Kryptos Connect API.

April 2026

New

POST /v1/integrations/{integrationId}/resync — trigger a resync on a user's connected wallet, exchange, or CSV integration. Supports latest (incremental refresh) and from_start (full re-ingestion) modes.
Developer Portal — optional per-client transaction limits for Guest users.
Kryptos Connect SDKs — published documentation for Web SDK, Mobile SDK, and the Connect Overview.
Web SDK — authMethods prop to restrict the auth options shown in the widget; email login and anonymous authentication.

Enhancements

GET /v1/holdings — each holding now includes a per-asset roi field (unrealizedPnL / costbasis * 100). The summary.roiPercentage field is unchanged.
GET /v1/transactions, GET /v1/nft-holdings, GET /v1/defi-holdings — the pagination object now includes totalCount, returned_count, hasNextPage, and hasPreviousPage. Existing limit and offset fields are unchanged.
GET /v1/holdings, GET /v1/transactions, GET /v1/nft-holdings — spam assets are now excluded by default. Pass ?isSpam=true to include them.
Web SDK — added language prop for UI localization.

Fixes

GET /v1/transactions — very small or very large amounts in the description string (e.g. "Received 1e-9 SOL from airdrops") are now rendered in fixed-decimal notation (e.g. "Received 0.000000001 SOL from airdrops").

Removed

Web SDK — baseUrl prop is no longer applicable and has been removed from the documentation.

New

Webhooks — added a Webhooks category to the docs covering setup and the supported event types.
Recipes — new "Recipes" category with a guide for posting transactions using API-key authentication.
Public Endpoints — added a Public Endpoints category with integrations documentation.
Kryptos Connect — sandbox mode section covering supported chains, test addresses, and error codes; user-flow variations and direct-integration examples.

Enhancements

GET /v1/transactions — added totalCostbasis and totalGains fields to transaction responses and type definitions.

Breaking

Kryptos Connect callbacks renamed: onSuccess → onConnectSuccess, onError → onConnectError.
