According to BlockBeats, on July 29, according to official news, the Cosmos ecosystem liquidity pledge agreement Stride released an airdrop update stating:
If a user received a STRD allocation by holding stTIA or stDYM on the Dymension or Agoric chains, they will need to link the address to a Stride address to claim its airdrop.
If the user does not hold stTIA or stDYM on the Dymension or Agoric chains, then nothing needs to be done.
The Stride airdrop page is now available for download.
