Sigma against other bots
Headline platform fees, lowest first. Sigma is number 10 of 12.
What comes on top of the platform fee
Every bot also passes on network costs: gas on EVM chains, priority fees and validator tips on Solana. On a busy launch, these can cost more than the platform fee itself.
Slippage is the other hidden cost: a 20% slippage setting on a thin memecoin can cost far more than a 1% fee. Keep it as low as the trade allows, and use anti-MEV modes where the bot offers them.
