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/AntelopeIO/reference-contracts --branch main --single-branch
cd reference-contracts/contracts/eosio.token
Step 2: Create Account for Contract
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/reference-contracts/contracts/eosio.token --abi eosio.token.abi -p eosio.token@active
Result should look similar to the one below:
Reading WASM from ...

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
