B18

📢B18 Testnet Public Beta Launch Announcement To further refine B18’s overall system architecture and user experience, and to complete comprehensive stress testing and mechanism validation prior to the official launch, B18 is now officially launching its testnet public beta. We sincerely invite all community members to participate, help polish product details, and contribute to the stable development of the ecosystem. 📄Public Beta Participation Guidelines 1. The public beta is now live. Users can participate with a very small amount of funds. It is recommended to use minimal funds (e.g., 0.1–1 USDC) for testing. Funds used in the testnet are non-refundable and will not generate any real returns; 2. During the testing period, team performance metrics will be amplified by 10,000x (e.g., reaching V1 requires 10,000 USDC in the mainnet, while only 1 USDC is needed in the testnet), to simulate real network growth and structure; 3. The minimum deposit threshold is reduced to 0.001 USDC, lowering participation barriers and enabling broader testing; 4. The testnet is completely independent of the mainnet and presale referral systems. Users can participate freely using any account; 5. The public beta will run until March 28, 24:00. Please plan your testing accordingly; 🔎Bug Bounty Program To ensure system security and stability, a bug bounty program is launched alongside the testnet: • Security vulnerabilities: 1,000–10,000 USDC • Logic issues: 500–5,000 USDC • Copy/text errors: 10 USDC per word 📩Bug Submission Methods: 1. Email: riccardimenzer@gmail.com 2. Dedicated Telegram support group For duplicate reports, rewards will be granted to the first valid submission. We welcome all community members to actively report issues and provide optimization suggestions to help improve system robustness. 🤳Testnet Access 🔗Testnet URL: nixdao.xyz 📌Testnet invitation address: 0xBE9c5d52718e05AD04e91eDC79D70034ed044b29 B18 is entering a critical stage before its official launch.

Core contract deployment and on-chain system infrastructure setup are now fully finalized, ensuring strong system stability and security. The platform has fully resumed operations, and all functions are now available for normal use. Official Website: b18.tech 2. Mainnet Core Contract Addresses To enhance transparency, on-chain verifiability, and user participation, the official B18 mainnet core contract addresses are now published.

Handling of Unpaid LP Presale Funds For users who participated in the LP presale but did not complete the final payment, a total of 321,450 USDC in presale funds has been fully transferred into the liquidity pool. These funds are now incorporated into the system’s liquidity mechanism to support overall protocol operations. 4. Liquidity Pool LP Burn Completed To further enhance protocol security and transparency, B18 has completed the burn of liquidity pool LP tokens: • LP tokens have been transferred to a black hole address • Liquidity credentials are permanently non-redeemable and non-recoverable • This ensures long-term stability and immutability of the liquidity pool Transaction Hash: 0x3325ad8181dfe8cabbde63d4d1b5b0c2e10d7e1af77ceb40af92702b995c72f2 Users can verify this transaction via the on-chain explorer: basescan.org This LP burn marks a further step in reinforcing decentralization, security mechanisms, and long-term trust in the B18 ecosystem. 5. LP Presale Order Claim Now Available Users who participated in the LP presale and completed the final payment can now claim their LP orders. All eligible orders have been migrated to the mainnet and are available for claim via the official website. 6. Airdrop Reward Token Mapping Completed The airdrop reward tokens will be fully mapped on-chain on March 29. All subsequent airdrop rewards will be distributed in B18 tokens. Closing B18 has now completed the critical transition from deployment to full operation. Moving forward, we will continue to optimize system performance, strengthen the on-chain ecosystem, and provide users with a more secure, transparent, and efficient experience. Thank you for your continued support and trust. B18 Operations Team March 29, 2026
