How to create, issue and transfer a token

Step 1: Obtain Contract Source

Navigate to your contracts directory.

cd CONTRACTS_DIR

Pull the source

git clone https://github.com/EOSIO/eosio.contracts --branch master --single-branch

cd eosio.contracts/contracts/eosio.token

Step 2: Create Account for Contract

[[info]] | You may have to unlock your wallet first!

cleos create account eosio eosio.token EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV

Step 3: Compile the Contract

eosio-cpp -I include -o eosio.token.wasm src/eosio.token.cpp --abigen

Step 4: Deploy the Token Contract

cleos set contract eosio.token CONTRACTS_DIR/eosio.contracts/contracts/eosio.token --abi eosio.token.abi -p eosio.token@active

Result should look similar to the one below:

Reading WASM from ...
Publishing contract...

#         eosio <= eosio::setcode               {"account":"eosio.token","vmtype":0,"vmversion":0,"code":"0061736d0100000001aa011c60037f7e7f0060047f...

warning: transaction executed locally, but may not be confirmed by the network yet         ]

Step 5: Create the Token

cleos push action eosio.token create '[ "eosio", "1000000000.0000 SYS"]' -p eosio.token@active

Result should look similar to the one below:

executed transaction: 0e49a421f6e75f4c5e09dd738a02d3f51bd18a0cf31894f68d335cd70d9c0e12  120 bytes  1000 cycles
#   eosio.token <= eosio.token::create          {"issuer":"eosio","maximum_supply":"1000000000.0000 SYS"}

An alternate approach uses named arguments:

cleos push action eosio.token create '{"issuer":"eosio", "maximum_supply":"1000000000.0000 SYS"}' -p eosio.token@active

Result should look similar to the one below:

executed transaction: 0e49a421f6e75f4c5e09dd738a02d3f51bd18a0cf31894f68d335cd70d9c0e12  120 bytes  1000 cycles
#   eosio.token <= eosio.token::create          {"issuer":"eosio","maximum_supply":"1000000000.0000 SYS"}

This command created a new token SYS with a precision of 4 decimals and a maximum supply of 1000000000.0000 SYS. To create this token requires the permission of the eosio.token contract. For this reason, -p eosio.token@active was passed to authorize the request.

Step 6: Issue Tokens

The issuer can issue new tokens to the issuer account in our case eosio.

cleos push action eosio.token issue '[ "eosio", "100.0000 SYS", "memo" ]' -p eosio@active

Result should look similar to the one below:

executed transaction: a26b29d66044ad95edf0fc04bad3073e99718bc26d27f3c006589adedb717936  128 bytes  337 us
#   eosio.token <= eosio.token::issue           {"to":"eosio","quantity":"100.0000 SYS","memo":"memo"}
warning: transaction executed locally, but may not be confirmed by the network yet         ]

Step 7: Transfer Tokens

Now that account eosio has been issued tokens, transfer some of them to account bob.

cleos push action eosio.token transfer '[ "eosio", "bob", "25.0000 SYS", "m" ]' -p eosio@active

Result should look similar to the one below:

executed transaction: 60d334850151cb95c35fe31ce2e8b536b51441c5fd4c3f2fea98edcc6d69f39d  128 bytes  497 us
#   eosio.token <= eosio.token::transfer        {"from":"eosio","to":"bob","quantity":"25.0000 SYS","memo":"m"}
#         eosio <= eosio.token::transfer        {"from":"eosio","to":"bob","quantity":"25.0000 SYS","memo":"m"}
#           bob <= eosio.token::transfer        {"from":"eosio","to":"bob","quantity":"25.0000 SYS","memo":"m"}
warning: transaction executed locally, but may not be confirmed by the network yet         ]

Now check if "bob" got the tokens using cleos get currency balance

cleos get currency balance eosio.token bob SYS

Result:

25.00 SYS

Check "eosio's" balance, notice that tokens were deducted from the account

cleos get currency balance eosio.token eosio SYS

Result:

75.00 SYS
