✨ Important knowledge points

• Store the Jetton content in the Cell data type.
• Use lowercase for the name in get_jetton_data() as per TEP-74. Otherwise, major explorers won't be able to read the Jetton information correctly.
• The max_supply parameter is optional. You can choose to use it or not. Regardless, the Explorer will only track the Total Supply in the Jetton Root Contract.
• In Jetton, if you want to transfer your Jetton Token to someone, you need to send a message to YOUR Jetton Wallet, not to the new recipient's wallet.
• forward_ton_amount can be set as lower as possible: Same as TelemintNFT. I don't know why, but looks like we can set (1e-9 TON) in forward_ton_amount without any error.

Deployment

To deploy contract you should:

1. Specify contract.tact that will be used as entry point of your contract
2. Configure contract.deploy.ts according to your contract.tact to generate a deployment link. In particular, it is necessary to correctly call the Init() function from the contract.

In here, set your specified content for Jetton in jettonParams variable of contract.deploy.ts. And replace fee_destination variable with your address in jetton.tact. When add/remove liquidity pair with this jetton, or purchase/sell this jetton from Ston.fi Dex pool, 5% of jetton amount will be transferred to fee_destination address.

If you renamed contract.tact to something else, you need to update tact.config.json correspondingly. For more information , see Tact Documentation

Testing

Example of contract tests are in contract.spec.ts. For more information about testing, see Tact Documentation

To add new test files to contract you should create *.spec.ts files similar to template's one and they would be automatically included in testing.
