Note that you don't pay anything apart from a network commission fee (0.00005 SOL) and DEXes commissions when you swap SOL to SBR, and later on lock it for veSBR, as well as vote on gauges for Saber eSOL-SOL LP. All Solana transactions are super fast to process and cost pretty nothing. In return, you gain voting power that helps you and other delegators gain the MAX returns from using Saber eSOL-SOL LP afterwards.
