Stellar Wallet Rotation and Testnet USDB Fix

Two Stellar wallet rotations and a bug fix that affected development-instance customers on Stellar testnet.

TL;DR

  • Fixed USDB issuer mismatch on Stellar testnet trustline and mint endpoints
  • Rotated the BlindPay operational wallet on Stellar mainnet
  • Rotated the USDB issuer on Stellar testnet (action required for development instances)

Bug fix: USDB issuer mismatch on Stellar testnet

The POST /create-asset-trustline and POST /mint-usdb-stellar endpoints were referencing a different USDB issuer than the one used by payins and payouts. This caused development-instance customers to see different tokens depending on the operation. Both endpoints now use the same issuer as all other operations.

No API contract changes — request and response schemas remain the same.

Mainnet operational wallet rotated

The BlindPay treasury wallet on Stellar mainnet has been rotated to GCOSSQDM2SWMHRP7CDBOLL2V45NHCRLUWUCEHPPBA2ABCOOLPOLZKIHE. This wallet receives payout crypto and sends payin crypto on Stellar mainnet. No action is required from customers — the system already uses the new wallet.

Testnet USDB issuer rotated

The USDB asset issuer on Stellar testnet has been rotated to GCQSSIMOW5OCGULZATDXKU5MOJBOMFX6G65X6CXZDQ7AIB3SKFUZ67NX.

Action required for development instances on Stellar testnet:

  1. Create a new USDB trustline via POST /create-asset-trustline
  2. Mint new USDB via POST /mint-usdb-stellar

Old USDB balances from the previous issuer are orphaned and no longer recognized by the system.
