Ethereum gas and EVM wallet context
Reviewed 7 October 2026
Bloom EVM exposes Ethereum buy, sell and approval gas controls alongside slippage and reusable presets. An ERC-20 approval is a separate permission/transaction step; the visible approval gas value is not part of Bloom’s platform percentage. The Ethereum settings show a MEV control, without proving a private relay identity.
The current Ethereum venue list includes Uniswap V2, V3 and V4. Copy trading and limits are confirmed, but an independent EVM liquidity/migration sniper remains unconfirmed. EVM uses one default-wallet logic across its supported chains; Solana wallets remain a separate context.
Platform fee and transaction costs
Bloom’s standard token buy/sell fee is 1%. Signing up through a referral reduces that platform fee to 0.9%. Network gas, priority fees or validator tips, protocol/DEX costs and bridge fees are separate. Referred cashback is 10% of eligible standard fees; the net result when combined with the discount remains unconfirmed.
