Trade ONE/USD

Harmony divides its network into four shards, each processing a subset of transactions in parallel. Each shard maintains its own state and runs its own BFT consensus with a subset of validators. Transactions between accounts on different shards are handled through cross-shard communication at the protocol level. This produces higher overall network throughput than a single-shard chain, with two-second finality and low transaction fees. Validators are randomly assigned to shards and reshuffled periodically to prevent targeted attacks on individual shards.

In June 2022, attackers compromised Harmony’s Horizon bridge, which connected Harmony to Ethereum and Binance Smart Chain, by obtaining two of the five private keys required to authorize transactions from the bridge’s multisig wallet. The attackers drained approximately $100 million in assets. Harmony proposed a recovery plan involving minting additional ONE tokens to reimburse affected users over time, though this created inflation concerns. The team has worked on rebuilding bridge infrastructure with stronger security assumptions since the exploit.

Harmony was home to DeFi protocols including DeFi Kingdoms, a play-to-earn RPG with its own token economy that generated significant chain activity at its peak. Following the bridge exploit, much of this activity migrated to other chains. Harmony’s ecosystem rebuilding effort has focused on attracting new protocols, improving developer tooling, and restoring user confidence through the recovery plan. Chain activity metrics such as daily active addresses and transaction volume are the most direct indicators of current ecosystem health.

No. ONE/USD on StoicFX is a Contract for Difference. You trade ONE’s price against the US dollar without holding any tokens. To stake ONE, participate in Harmony governance, or interact with applications on the Harmony network, you would need actual ONE tokens in a compatible wallet.
