Solana Mobile has launched its first official yield product, a USDC Earn Vault inside the Seed Vault Wallet for Seeker users. Built with Kamino, Solana’s biggest lending market, the vault offers variable, compounding yield without minimum deposits, withdrawal limits, lockups, withdrawal fees or exit queues. It allocates 95% of assets under management to Kamino’s SOL/BTC market lending pool and keeps 5% in reserve for withdrawals, with a 0.25% protocol fee and no additional performance fees. The launch follows Seeker Summer activity that made users eligible for up to 89 million SKR, valued at more than $626,000, with more than half of distributed SKR staked to the network. Solana Mobile is also changing its activity-scoring system to discourage artificial transactions and prioritize organic usage; the changes will not apply retroactively.
