Yes, in two cases. The Solana migration is complete: your cards are on Solana and your ETH is on Base. Most accounts need nothing. If you still had cards or ETH on StarkEx, they need one action from you.
Cards left on StarkEx
Log in to Sorare. At your first login after the migration, Sorare creates your Solana address and mints your cards into it. You can then use them in competitions and on the market.
ETH left on StarkEx
Your ETH does not move on its own. Your wallet shows 0 ETH until you click Migrate ETH. The fee is 0.003 ETH. See My ETH balance shows 0.
If it does not work
If your cards do not show after you log in, contact support. Send your Sorare username.
