PassetHub Contract Suite

A set of five Solidity contracts (Crowdfunding, MultisigWallet, ERC20Basic, Voting, Lock) ported from Sepolia to Polkadot’s EVM (Passet Hub). Each contract is fully tested, deployed, and verified on Passet Hub.

• Analysis:https://github.com/web3devz/ETH-Belgrade/blob/main/analysis.md

Conclusion:

• I noticed that deployment and function‐call gas usage on Passet Hub closely matches Sepolia’s, demonstrating strong EVM consistency.

• I observed that block times on Passet Hub (~6 s) are significantly faster than Sepolia’s (~15 s), which improves UX and transaction finality.

• However, I also noticed that some standard tooling—like on‐chain explorers—on Passet Hub is still less mature than Sepolia’s, making certain verifications a bit more involved.

• Additionally, I found that fewer faucet and community resources on Passet Hub mean the initial setup can be slightly trickier than on Sepolia.
