Web4 is a gateway to the smart contracts deployed to NEAR protocol.
This demo just shows the minimum viable application that lives on NEAR chain, and thus anyone hosting the gateway can serve all the Web4 projects!
See it live on testnet: https://hello-web4-python.testnet.page
When you deploy on mainnet, you should be able to use https://ACCOUNT_ID.near.page as your gateway.
Use near-py-tool CLI to build it.
Install:
python -m venv ./venv
. ./venv/bin/activate
pip install near-py-tool
Build:
near-py-tool build non-reproducible-wasm
Using near-cli-rs you can deploy the contract to your account:
near contract deploy hello-web4-python.testnet use-file build/near-web4-demo-py.wasm without-init-call
There is a demo of this project available in Rust.
