Day 79 – Solidity Development

Was a bit busy with end-sem internals and practicals

✅ Added dynamic pricing — higher price for public users, lower for whitelisted users
✅ Implemented owner withdrawal of funds collected from NFT sales
✅ Enabled direct NFT transfer by owner

Day 78 – Solidity Development

Today I built and deployed an NFT project using ERC-721.

✅ Created an NFT smart contract using ERC-721 standard
✅ Deployed the project on the Sepolia testnet
✅ Implemented a whitelist (approved users) mechanism
✅ Only whitelisted users (approved by owner) can get early access to mint NFTs

More functionality will be added tomorrow to further improve the project

Day 77 – Solidity Development

Today I explored advanced concepts around NFTs and EVM internals.

✅ Learned what SVG is and how it’s used in NFTs
✅ Created a dynamic NFT collection
✅ Encoded SVGs to store fully on-chain
✅ Modified NFT metadata/images directly on-chain
✅ Deployed and interacted using Anvil (local blockchain)
✅ Explored advanced EVM opcodes and low-level calls
✅ Learned about EVM encoding & function selectors
✅ Understood how to verify transactions in MetaMask

Diving deeper into low-level Solidity and fully on-chain NFT design.

Day 76 – Solidity Development

Today I explored the world of NFTs and ERC-721.

✅ Learned about the ERC-721 standard
✅ Understood what NFTs are and how they work
✅ Explored IPFS for decentralized storage
✅ Uploaded and used data via IPFS
✅ Deployed an NFT smart contract on testnet
✅ Compared IPFS (Pinata) vs HTTP vs On-chain SVGs

Day 75 – Solidity Development

Started diving into Advanced Foundry today.

✅ Learned how to create an ERC-20 token
✅ Explored deeper concepts in Foundry development workflow

Moving towards more advanced smart contract development and standards.

Day 74 – Solidity Development

Completed the Escrow project with full frontend integration.

✅ Built the UI for the Escrow project
✅ Successfully integrated frontend with the smart contract
✅ End-to-end functionality working smoothly

[spydy.eth @0xspydy]

🐉
Day 73 – Solidity Development

Continued building the Escrow Smart Contract with more advanced features.

✅ Added admin controls to cancel and release funds
✅ Implemented logic for automatic fund release once the seller completes delivery
✅ Used Chainlink Automation (Keepers) for triggering actions
✅ Deployed and tested the contract on the Sepolia testnet

Project is getting closer to a real-world use case with automation and proper fund management..

Day 72 – Web3 Development

Started the Escrow Smart Contract project today.

✅ Initial contract written
✅ Buyer can fund the escrow
✅ Buyer can cancel and retrieve funds if the seller doesn’t deliver

Planning to add more business logic and functionality tomorrow. Step by step building a secure escrow system.
