After eBTC airdrop it will start the airdrop for the old proxy i guess, do you know any info about the swap to the old proxy owner? thanks
Take a look at the ebtc website.

For holders of the old PRXY tokens, a SEPARATE swap date will be announced soon, at which date and time the new ePRX tokens will replace the old PRXY tokens.
