Arbitrum's ARB token launches on Solana via Sunrise gateway, touting 10x lower fees and better spreads; Arbitrum co-founder defends its MEV protections as a different trade-off.

The ARB token is now available on Solana through the Sunrise gateway, with the announcement claiming 10x lower fees and better spreads than on Arbitrum itself. The post lists Solana apps where the token can be used, including Phantom, Jupiter, Raydium, Backpack, and others, and directs users to verify the contract address via Tokens. The announcement quotes a post from Toly, who disputes the claims, arguing that spreads on Arbitrum are currently worse and fees higher, and that Arbitrum's 10% fee rake exceeds the sandwich rate by a factor of 10x, describing it as a single sequencer maximizing shareholder value.
