Tips and Tricks

Can't figure something on Polkadot? Try checking out the Polkadot Support site - https://support.polkadot.network/support/home

Interested in knowing which projects are working to create parachains for Kusama and Polkadot? Check out the Rococo testnet and which projects are creating parachains for it. https://polkadot.js.org/apps/?rpc=wss%3A%2F%2Frococo-rpc.polkadot.io#/parachains

Want an address with specific letters, words, or numbers in it? For example, make your address have "Yay" in it, such as 1YaYDVuFPFMt6exU4gTzgVvXXRaKXmAv4D8FD6H2aZ4fBtK. You can use the Polkadot-JS vanity generator (https://polkadot.js.org/apps/#/accounts/vanity). Learn how at https://support.polkadot.network/support/solutions/articles/65000171416-dot-vanity-addresses-and-recognizable-dot-icon-avatars

Interested in interacting with Polkadot programmatically? You can find information and tutorials on using the Polkadot API here: https://polkadot.js.org/docs/api/

If you are the type of person who reads down to here in the Weekly Digest, you'd probably make an excellent grants evaluator at Web3 Foundation! https://web3.bamboohr.com/jobs/view.php?id=85

Or perhaps a Technical Educator intern / entry-level candidate, teaching people about Polkadot. https://web3.bamboohr.com/jobs/view.php?id=84
