Learning area
Build, understand and document
I am a full-stack developer exploring Web3 as a complementary technical field: smart contracts, EVM networks, wallets and on-chain data. This page documents what I build and learn, together with the associated risks and limitations.
Experiment
With bounded prototypes and explicit risks
Build
EVM smart contracts and React interfaces
What interests me
Web3 Ecosystem
⛓️
Blockchains
Understanding major blockchain ecosystems and their approaches: Bitcoin, Ethereum, EVM chains, Cosmos, Solana, Polkadot and scalability-focused networks.
Bitcoin
The first decentralized cryptocurrency, designed as a store of value and peer-to-peer monetary network.
Network data prototype
Blockchain Explorer — experimental
Live EVM network snapshots: latest block, chain ID, gas price, max fee, priority fee and explorer links.
Analysis prototype
Wallet Inspector — experimental
Transactional prototype
On-chain donation — demonstration
A real EVM interaction
This prototype can send an EVM donation to the displayed address from a compatible wallet.
Confirming inside the wallet triggers a real and potentially irreversible transaction. Verify the network, token, amount, receiver address and fees before confirming.
Receiver address
0x718a544638Fd113A58C1062E4b2E8a404b13D2eCUse search to find another network or token.
- Choose the network and token
- Set the amount
- Review, then confirm in the wallet
