How I Rebuilt My Blockchain Indexer From Scratch — And What I Learned
medium.com
The past few days have been hectic. Here’s the full breakdown of the problems I hit and how I fixed them. Building a blockchain indexer sounds straightforward — until it isn’t. I’ve spent the last few days deep in the trenches working on one for my company, and along the way hit a series of problems that forced me to rethink the entire architecture. This is that story. The Problems 1. Free-tier RPC URLs ran out of compute units in under 12 hours The first mistake was relying on free-tier RPC endpoints. T...
Why Your Solidity Contract Wouldn’t Deploy — And How One Number Fixed It

A real debugging story involving Foundry, a low-gas testnet, and the optimizer setting nobody talks about I was deploying an AirDropFactory contract to a custom testnet. The script ran. Foundry printed a transaction hash. Then… nothing. Five minutes of a spinning cursor, and then a timeout. ⠠ [Pending] 0x83a58342ec9d66a3934522ac0b085b94a351e6f4d2c6f0dbeeacab31e1716757 ⠖ [00:05:08] [████████████████████] 1/1 txes (0.0s) ⠖ [00:05:08] [--------------------] 0/1 receipts (0.0s) The contract wasn’t deployed. ...
Why You Should Use a Clean Wallet for Multi-Chain Smart Contract Deployments
medium.com
When building a multi-chain DeFi protocol, deployment hygiene becomes just as important as smart contract security. Recently, while deploying a DEX-style ecosystem (Factory + Router + Wrapped Token), we encountered a subtle but critical issue: Using the same wallet across multiple chains can break deterministic deployment architecture. Let’s break down why that happens — and why using a clean wallet matters. How Contract Addresses Are Generated On EVM chains, contract addresses are not random. They are d...

The problem FreelanceDAO solves Traditional freelance platforms are often expensive, slow to pay, and controlled by a central authority. This project offers a decentralized, trustless alternative built on the blockchain. Eliminates High Fees & Delays: By removing the middleman, FreelanceDAO reduces costs to minimal gas fees and ensures instant payments upon milestone approval. Provides Trust & Security: Smart contracts automate project agreements and lock funds in a secure escrow, guaranteeing payment for completed work. Ensures Transparency: User profiles, work history, and reputation are stored immutably on-chain, preventing censorship or manipulation. Gives Users Control: Your wallet is your identity. Users have full control over their funds and professional data without relying on a platform's permission.
