A pallet implementing ERC-20 functionality on top of the substrate-node-template (original docs: https://github.com/substrate-developer-hub/substrate-node-template). Implements the basic functions such as transfer, approve, transferFrom, increaseAllowance, decreaseAllowance. The starting point is the init function, where a user can set the total supply, the name of token and its symbol. User, who called init function, gets all obtainable tokens.
Use Rust's native cargo command to build and launch the template node:
cargo run --release -- --devThe cargo run command will perform an initial build. Use the following command to build the node
without launching it:
cargo build --releaseTo test the pallet run the following command:
cargo test --package pallet-erc- Broken macros
- Took a lot of time to organize everything just to compile it for the first time.
- Build config broken by Fleet
- Tried using Fleet instead of Cargo, what led to the broken and irreparable build config. Due to the first successful build, I could not understand the root of the problem and messed with it for several days.
- Usage of BoundedVec in Events
- For some reason it is impossible to use BoundedVec in Events even with the pallet::without_storage_info macro.
