Deploy CW20(Fungible Token) Contract​

Compile Sample Contract​

Clone cw-plus

git clone https://github.com/CosmWasm/cw-plus.git
cd cw-plus
docker run --rm -v "$(pwd)":/code \
  --mount type=volume,source="$(basename "$(pwd)")_cache",target=/target \
  --mount type=volume,source=registry_cache,target=/usr/local/cargo/registry \
  cosmwasm/optimizer:0.15.0

for Apple Silicon

docker run --rm -v "$(pwd)":/code \
  --mount type=volume,source="$(basename "$(pwd)")_cache",target=/target \
  --mount type=volume,source=registry_cache,target=/usr/local/cargo/registry \
  cosmwasm/optimizer-arm64:0.15.0

Upload Contract​

cd artifacts

Store CW20(Fungible Tokens) contract Reference: https://github.com/CosmWasm/cw-plus/blob/main/packages/cw20/README.md

RES_STORE=$(myceld tx wasm store cw20_base-aarch64.wasm --from alice --gas auto --gas-adjustment 1.3 --output json -y)

Get the transaction hash

TX_STORE=$(echo $RES_STORE | jq -r '.txhash')

Get code-id

CODE_ID=$(myceld q tx $TX_STORE --output json | jq -r '.logs[0].events[-1].attributes[1].value')

Initialize Contract​

Create request body to initialize

MY_ADDRESS=$(myceld keys show alice --output json | jq -r '.address')
TOKEN_NAME=SampleToken
TOKEN_SYMBOL=SAMP

INIT=$(jq -n --arg name "$TOKEN_NAME" --arg symbol "$TOKEN_SYMBOL" --arg address "$MY_ADDRESS" '{"name":$name,"symbol":$symbol,"decimals":6,"initial_balances":[{"address":$address,"amount":"10000000"}]}')

Initialize the contract

RES_INIT=$(myceld tx wasm instantiate "$CODE_ID" "$INIT" --label "$TOKEN_NAME" --admin alice --from alice -y --output json)

Get the transaction hash

TX_INIT=$(echo $RES_INIT | jq -r '.txhash')

Get contract address

CONTRACT_ADDRESS=$(myceld q tx $TX_INIT --output json | jq -r '.logs[0].events[-1].attributes[0].value')

Create query body

BALANCE=$(jq -n --arg address "$MY_ADDRESS" '{"balance":{"address": $address}}')

Query balance

myceld q wasm cs smart "$CONTRACT_ADDRESS" "$BALANCE"
