Some participants have been confused between a Cyto address and an Airdrop address. Cyto addresses are prefixed with "C" while Airdrop addresses start with "Ax0". For example,
Cyto address:
CkoRfc5CJKP7CLgeuypH93hoY4s3PHKT5J8wa1m3pV67SmBndH3brdYCMGDKX36jBH2YrX1h54zE5fVWz58BS2aF1GckJTN
Airdrop address:
Ax03519b57f516cdd58f8b2bd984edb987ace7a87fad7e6b9d55a5921fbb02066dea
Due to how Cyto will launch, Cyto airdrop addresses are necessarily different from normal Cyto addresses.
When you join the airdrop make sure to generate and submit an Airdrop address starting with "Ax0" by following the instructions carefully in the second post.
Tip: It's also a good idea to save a copy of your airdrop receipt for your paperwork and proof for tax purposes, etc.
