required skills:
* smart contract development: solidity (ethereum, bsc), rust (solana, polkadot), vyper
* testing & debugging: hardhat, foundry, truffle, brownie, remix ide
* blockchain interaction: web3.js, ethers.js, the graph, moralis, chainlink oracles
* smart contract security: openzeppelin, slither, mythx, certik, forta (handling reentrancy, overflow, mev attacks)
* token standards & defi concepts: erc-20, erc-721 (nfts), erc-1155, bep-20, amms, staking, liquidity pools
* dapp frontend (optional): react.js, next.js, web3 ui frameworks
what will you do?
* design, write, and deploy smart contracts on ethereum, solana, bsc, or polkadot
* optimize gas efficiency and reduce transaction costs
* ensure security best practices in smart contracts to prevent hacks/exploits
* test smart contracts using hardhat, foundry, truffle, or brownie
* integrate smart contracts with dapps using web3.js, ethers.js
* collaborate with backend engineers to store and retrieve blockchain data
* stay updated on blockchain advancements (new ethereum standards, solana updates, zk-rollups, layer 2 scaling)
