Here's what happened when a once-promising layer-1 network finally threw in the towel after getting exploited one too many times.

There is nothing worse for an investor than holding bags while watching a chain's underlying infrastructure completely collapse. You back a project believing in its technology, only to realize that persistent security flaws can wipe out years of adoption in a single afternoon.

The downfall of Harmony $ONE is a sobering case study in how cumulative security failures destroy user trust. It started with the 2022 Horizon bridge exploit that drained $100 million, followed by a minting bug in 2023. The final blow came when attackers illegally minted roughly 2.4 trillion unauthorized $ONE tokens, forcing the core team to admit that defending the network was no longer financially sustainable. Rather than fighting an uphill battle, they announced plans to shut down the chain entirely and migrate remaining users to $ETH via a snapshot airdrop.

When you compare this trajectory to resilient networks like $SOL that weathered massive outages and market crashes to rebuild their ecosystem, it highlights how crucial battle-tested code really is. We saw similar bridge-related collapses during the last cycle, but seeing an established layer-1 give up its sovereign chain to become an Ethereum token proves that not every network is built to survive the long game.

Do you think we will see more struggling layer-1 chains abandon their native networks to pivot into Ethereum tokens?
