Is there a step by step guide on how to deploy smart contract in the Astar ecosystem?
Yes, you can follow this tutorial within our documentation.
You sure can.
What are the names of the native tokens in the Astar ecosystem?
SBY (Shibuya - Testnet tokens)
SDN (Shiden Network)
ASTR (Astar Network)
How do I connect to Astar networks, RPCs, Network name, Chain ID?
You can visit this page.
How can I get test tokens (SBY)?
Use our faucet.
Is it possible to import Substrate (Polkadot) addresses to Metamask?
No. Polkadot (Substrate framework) uses a 256 bit address, while Metamask uses a 160 bit address.
Can I interact with EVM contracts by using existing Substrate account (non-ecdsa)?
Any Substrate account can call the EVM, and its Native address will be mapped to an EVM compatible representation.
I was able to deploy contracts in other networks, but contracts deployed in this network show "out of gas" error with the error code of 0. How do I fix it?
Contract size limits may differ between networks, so it is recommended to lower optimizer runs of the same smart contract and adjust it to a compatible size for the network. You may want to tune this on testnet.
During contract deployment I'm getting
HH110: Invalid JSON-RPC response received: 403 Forbidden error.
That means your requests are limited by Astar endpoints. You need to set up your own node or use another endpoint provider.
