999DEX: First DeFi Platform Live on BlockDAG | Tutorial: Avoid the berlin EVM Gotcha

[pumpz999]

999DEX is live on BlockDAG mainnet 🔱

For anyone building on BlockDAG, 999DEX (999dex.com) is now the first full-featured DEX on the chain.

Quick recap of what's deployed:

• BondingCurve + AMM DEX
• Token/NFT/DAO/Multisig/Staking factories (Contract Studio)
• Solidity IDE in-browser
• $999 staking (50% of fees)

The most important tip for BlockDAG builders:

// Always set evmVersion: "berlin" — BlockDAG doesn't support PUSH0
solidity: {
  version: "0.8.20",
  settings: { evmVersion: "berlin" }
}

Happy to answer any questions about building on BlockDAG. 🙏
