Simple token contract using Rust for Vaulta (prev. EOS) blockchain

Build Step:

What you need:

• Rust version 1.79.0 (or any version less than 1.82, because Vaulta does not support wasm bulk memory ops)
• wasm-bindgen 0.2 (However, you need #[no_mangle] in your source code for exporting the apply function which is the entry point for Vaulta smart contract)
• wasm-pack

See https://developer.mozilla.org/en-US/docs/WebAssembly/Guides/Rust_to_Wasm for installation

Steps to build:

clean_build.sh

You will get the wasm file in

./target/wasm32-unknown-unknown/release/hello_wasm.wasm

Deploy to Vaulta Blockchain

In this example, the test account is a123

cleos set code a123 ./target/wasm32-unknown-unknown/release/hello_wasm.wasm
cleos set abi a123 ./token.abi

Create your own token

cleos push action a123 create '{"issuer":"a123","maximum_supply":"1000000.0000 RUST"}' -p a123

issue token

cleos push action a123 issue '{"to":"a124","quantity":"100.0000 RUST","memo":"hihi"}' -p a123
executed transaction: 5586add21a12371660df3d24ea1542d94ec79db8c086cd01e7d2280788567470  128 bytes  954 us
#          a123 <= a123::issue                  {"to":"a124","quantity":"100.0000 RUST","memo":"hihi"}
warning: transaction executed locally, but may not be confirmed by the network yetult         ]

transfer token

cleos transfer a124 a125 "1.0 RUST" -c a123
executed transaction: 924977560c3aca6c01ba9fe4636a948978765076df2014caba9ca1ec574f35a9  128 bytes  968 us
#          a123 <= a123::transfer               {"from":"a124","to":"a125","quantity":"1.0000 RUST","memo":""}
warning: transaction executed locally, but may not be confirmed by the network yetult         ]

get token balance of account a124

cleos get currency balance a123 a124
99.7000 RUST

get currenty stats

cleos get currency stats a123 RUST
{
  "RUST": {
    "supply": "301.0000 RUST",
    "max_supply": "1000000.0000 RUST",
    "issuer": "a123"
  }
}
