How to decide
Match the tool to an actual requirement, then check its fee quote and wallet setup.
22 comparison dimensions have at least one unverified value. Start with the controls you need for your Arc workflow, then use the official documentation linked from each bot guide. A lower platform fee alone does not establish a lower total execution cost.

Arc pools and chain-scoped strategies
Reviewed 7 October 2026
Arc is current trading support, rather than only an announcement. The documented Arc Uniswap V2/V3/V4 routes and launch platforms have explicit chain-scoped roles. AFK platform matching and token trading are separate relations; no additional launchpad sniper support is inferred.
Arc’s settings expose gas, slippage, presets and strategy defaults. Its venue matrix includes native-USDC pool semantics; these must not be substituted with Ethereum’s gas/quote assumptions. The inspected panel did not establish a MEV control or a private relay.
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.
