From cefedcbbb960ec138edc7bdf9a2a23abf526f877 Mon Sep 17 00:00:00 2001 From: joshuanelsoncod-source Date: Tue, 28 Jul 2026 12:20:04 +0000 Subject: [PATCH 1/4] fix: remove hardcoded API key from TypeScript SDK The validationcloud.io RPC endpoint had a hardcoded API key embedded in the SDK source code. Replace with public Stellar mainnet endpoint. Callers can provide their own RPC URL via TrustLinkClientOptions.
