Solana has attributed the 17-hour outage it suffered last week to a denial-of-service attack aimed at Grape Protocol’s Sept. 14 initial DEX offering (IDO). In a Sept. 21 blog post, the Solana Foundation stated that bots spammed the network as Grape launched its IDO on the Solana-based decentralized exchange (DEX) Raydium at 12:00 UTC last Tuesday. The botting activity overwhelmed the network with a transaction load of 400,000 per second, with Solana noting that “unbounded growth of the forwarder queues and resource-heavy blocks” resulted in a number of forks being automatically proposed to the network.
