在 巴西 購買 Harmony Horizon Bridged USDC (Harmony) (1USDC)

Harmony Horizon Bridged USDC, identified by the symbol 1usdc, is a synthetic digital asset that exists on the Harmony blockchain. It was designed to represent USD Coin on the Harmony network, allowing users to interact with the broader decentralized finance ecosystem while utilizing the speed and efficiency of the Harmony protocol. The token was originally issued through the Horizon Bridge, a cross-chain infrastructure developed by Harmony to facilitate the transfer of assets between its network and other blockchains such as Ethereum and Binance Smart Chain. Under normal operations, the bridge functioned by locking native USDC in a secure vault on the source chain and then minting an equivalent amount of 1usdc on the Harmony blockchain. This process ensured that every 1usdc in circulation was intended to be backed by actual USDC held in reserve. Within the Harmony ecosystem, 1usdc served as a stable medium of exchange. It was widely used in liquidity pools, decentralized lending platforms, and as a unit of account for various on-chain services. By bridging USDC to Harmony, participants could engage in yield farming and other financial activities without the high gas fees typically associated with the Ethereum mainnet. The project faced a significant challenge in June 2022 when the Horizon Bridge was the target of a major security exploit. During this event, unauthorized parties gained access to the bridge's administrative keys and removed the underlying collateral assets from the Ethereum-side vaults. This breach directly impacted the security and backing of 1usdc, as the physical assets that were supposed to guarantee its value were no longer available in the bridge reserves. In the period following the exploit, the Harmony team and its community have focused on recovery efforts. These initiatives have included proposals for ecosystem restoration and various strategies to address the losses experienced by holders of bridged assets. The status of 1usdc is closely tied to these ongoing governance decisions and the long-term roadmap of the Harmony protocol as it works to move beyond the security incident and rebuild its cross-chain infrastructure. Currently, it remains a legacy asset from the original Horizon Bridge era. 瞭解更多
