An unstructured, spaghetti token created on the JeChain network using Jelscript

What is Tacoin?

Tacoin is an unstructured, spaghetti token created on the JeChain network using Jelscript. It doesn't follow any standards whatsoever, and exist just to be a fun example.

The code

You can check out the file tacoin.jel, but here it is basically:

pull contract_balance, insert_contract_address_here
equ contract_balance, 0
jump $contract_balance, release_token
jump 1, transfer

label release_token
	store insert_contract_address_here, 297297297

label transfer
	address sender_address
	pull sender_balance, $sender_address
	lss sender_balance, %0
	jump $sender_balance, eof

	pull receiver_balance, %1
	pull sender_balance, $sender_address
	add receiver_balance, %0
	sub sender_balance, %0

	store $sender_address, $sender_balance
	store %1, $receiver_balance

label eof

Explanation

It will get the token balance of the contract, if it's equal to 0, the contract will jump to the release_token label and proceeds the execution, if not, it will jump straight to transfer.

With release_token, you can see that I have stored 297297297 into the contract address, which means the initial total supply is 297297297 Tacoins held by the contract.

With transfer, you can see that the contract checked if sender's balance is less than the amount they send or not. If yes, it will quit executing by simply jumping to eof which is the end of the program. Or else, it will get balance of sender and receiver and change them.

Deploy

Setup a JeChain node, and then paste this code at the bottom of jenode.js:

const contract = `SC
pull contract_balance, insert_contract_address_here
equ contract_balance, 0
jump $contract_balance, release_token
jump 1, transfer

label release_token
	store insert_contract_address_here, 297297297

label transfer
	address sender_address
	pull sender_balance, $sender_address
	lss sender_balance, %0
	jump $sender_balance, eof

	pull receiver_balance, %1
	pull sender_balance, $sender_address
	add receiver_balance, %0
	sub sender_balance, %0

	store $sender_address, $sender_balance
	store %1, $receiver_balance

label eof
`;

const deployContract = new Transaction(publicKey, contract, 0, 0);

deployContract.sign(keyPair);

sendTransaction(deployContract);

Deploy in mainnet/testnet

JeChain currently doesn't have a public community to have a mainnet/testnet, but if you happen to find one, just simply connect to their nodes and deploy the contract.

Deploy in testing environment

Just don't connect to any nodes and run the node in localhost :D.
