Dero Stargate DVM Smart Contracts guide to install and test various function of private token Smart Contract.
Download Dero Stargate testnet source and binaries.
Start Dero daemon in testnet mode.
./derod-linux-amd64 --testnet
Start Dero wallet in testnet.
dero-wallet-cli-linux-amd64 --rpc-server --wallet-file testnet.wallet --testnet
Start Dero wallet second instance to test transfer/ownership functions etc.
dero-wallet-cli-linux-amd64 --wallet-file testnet2.wallet --testnet --rpc-server --rpc-bind=127.0.0.1:40403
Dero testnet Explorer, Not required but if you want to host your own explorer for privacy reasons.
./explorer-linux-amd64 --http-address=0.0.0.0:8080
Connect to explorer using browser on localhost:8080

To send DERO to multiple users in one transaction
curl http://127.0.0.1:40403/json_rpc -d '{"jsonrpc":"2.0","id":"0","method":"transfer","params":{ "transfers":[{"amount":100000,"destination":"deto1qxqqen6lqmksmzmxmfqmxp2y8zvkldtcq8jhkzqflmyczepjw9dp46gc3cczu"},{"amount":300000,"destination":"deto1qxqqen6lqmksmzmxmfqmxp2y8zvkldtcq8jhkzqflmyczepjw9dp46gc3cczu"}] }}' -H 'Content-Type: application/json'
DERO has 2 types of SCs, public and private.
- Public SCs are public with all data/code/exchanges are public.
- Private SCs have their smart contract data public. But no one knows how many tokens a particular user own or how much is he sending or how much is he receiving. Best example is to understand private SCs as banks and private tokens as cash. Once cash is out from the bank, Bank doesn't know "who has what amount or how is it being used/sent/received etc.". This makes all private tokens completely private.
Installing Private Smart Contract.
Download token.bas
curl --request POST --data-binary @token.bas http://127.0.0.1:40403/install_sc
To check private token balance in wallet, type this command in wallet.
balance SCID
Download SC Code,check SC balance and variables from chain
curl http://127.0.0.1:40402/json_rpc -d '{"jsonrpc":"2.0","id":"0","method":"getsc","params":{ "scid":"aacaa7bb2388d06e523e5bc0783e4e131738270641406c12978155ba033373af" , "code":true}}' -H 'Content-Type: application/json'
Examples of various private token Smart Contract functions Eg: To send private tokens from one wallet to another wallet, this does not involve SC Eg: this also showcases to send multiple assets( DERO and other tokens on DERO Network) within a single transaction
curl http://127.0.0.1:40403/json_rpc -d '{"jsonrpc":"2.0","id":"0","method":"transfer","params":{ "transfers":[{"amount":111111,"destination":"deto1qxqqen6lqmksmzmxmfqmxp2y8zvkldtcq8jhkzqflmyczepjw9dp46gc3cczu"},{"amount":333333,"destination":"deto1qxqqen6lqmksmzmxmfqmxp2y8zvkldtcq8jhkzqflmyczepjw9dp46gc3cczu","scid": "aacaa7bb2388d06e523e5bc0783e4e131738270641406c12978155ba033373af" }] }}' -H 'Content-Type: application/json'
Eg: Convert DERO to tokens 1:1 swap, we are swapping 44 DERO atomic units to get some tokens
curl http://127.0.0.1:40403/json_rpc -d '{"jsonrpc":"2.0","id":"0","method":"transfer","params":{"transfers":[{"amount":1,"destination":"deto1qxqqen6lqmksmzmxmfqmxp2y8zvkldtcq8jhkzqflmyczepjw9dp46gc3cczu", "burn":44}],"scid":"aacaa7bb2388d06e523e5bc0783e4e131738270641406c12978155ba033373af", "sc_rpc":[{"name":"entrypoint","datatype":"S","value":"IssueTOKENX"}] }}' -H 'Content-Type: application/json'
Convert tokens to DERO 1:1 swap, we are swapping 9 token atomic units to get 9 DERO atomic units This tx shows transferring tokens natively, no dero fees etc, this is under evaluation, **Currently these show as coinbase rewards **
curl http://127.0.0.1:40403/json_rpc -d '{"jsonrpc":"2.0","id":"0","method":"transfer","params":{"transfers":[{"scid":"aacaa7bb2388d06e523e5bc0783e4e131738270641406c12978155ba033373af", "amount":1,"destination":"deto1qxqqen6lqmksmzmxmfqmxp2y8zvkldtcq8jhkzqflmyczepjw9dp46gc3cczu", "burn":9}],"scid":"aacaa7bb2388d06e523e5bc0783e4e131738270641406c12978155ba033373af", "sc_rpc":[{"name":"entrypoint","datatype":"S","value":"ConvertTOKENX"}] }}' -H 'Content-Type: application/json'
Eg: To withdraw balance only for smart contract owner
curl http://127.0.0.1:40403/json_rpc -d '{"jsonrpc":"2.0","id":"0","method":"transfer","params":{ "transfers":[{"amount":111111,"destination":"deto1qxqqen6lqmksmzmxmfqmxp2y8zvkldtcq8jhkzqflmyczepjw9dp46gc3cczu"}],"scid":"aacaa7bb2388d06e523e5bc0783e4e131738270641406c12978155ba033373af", "sc_rpc":[{"name":"entrypoint","datatype":"S","value":"Withdraw"}, {"name":"amount","datatype":"U","value":2 }] }}' -H 'Content-Type: application/json'
Eg: To transfer ownership of smart contract to new address/owner
curl http://127.0.0.1:40403/json_rpc -d '{"jsonrpc":"2.0","id":"0","method":"transfer","params":{ "transfers":[{"amount":111111,"destination":"deto1qxqqen6lqmksmzmxmfqmxp2y8zvkldtcq8jhkzqflmyczepjw9dp46gc3cczu"}],"scid":"aacaa7bb2388d06e523e5bc0783e4e131738270641406c12978155ba033373af", "sc_rpc":[{"name":"entrypoint","datatype":"S","value":"TransferOwnership"}, {"name":"newowner","datatype":"S","value":"deto1qxsplx7vzgydacczw6vnrtfh3fxqcjevyxcvlvl82fs8uykjkmaxgfgulfha5" }] }}' -H 'Content-Type: application/json'
Eg: To claim ownership of smart contract
