0xD39

0xD39 is an Ethereum blockchain address that appears in transaction logs and exchange listings as the location of a smart contract associated with the D39 token. The contract was first validated and uploaded to the Etherscan explorer on March 12, 2023, with a transaction hash of 0x4b92f... The source code was submitted as a Solidity contract that implements the ERC‑20 standard, enabling the creation and transfer of the D39 token.

The contract’s bytecode size is 8,412 bytes, a typical length for contracts that include access control mechanisms and a snapshot feature to support a voting process. According to the Etherscan verification data, the contract utilizes OpenZeppelin’s ReentrancyGuard and Ownable libraries, providing a standard security framework for ownership and transaction reentrancy checks.

During the initial rollout, the contract was provisioned with an initial supply of 1,000,000 D39 tokens, which were distributed to a handful of seed investors and retained for a liquidity pool on Uniswap V3. The token’s symbol, “D39,” and its decimal precision, 18, are both displayed in the contract’s “name” and “decimals” functions, providing compatibility with most crypto wallets and exchanges.

In early 2024, a regulatory audit flagged the contract for a potential front‑running vulnerability, specifically an unchecked allowance manipulation in its transferFrom logic. The contract owner responded by issuing a new version, 0xD39‑v2, that implements the permit feature and adds slippage checks. Exchange listings of the newer token have since migrated to the updated address.

The 0xD39 address continues to appear in token transfer activity, predominantly as a component of yield‑staking protocols that allow users to lock their D39 tokens in return for a fixed-rate interest over a 30‑day period. Its visibility remains high in analytics dashboards focused on DeFi yield harvesters, and it is listed in the top 500 tokens on several price tracking sites.
