ERC-1363 (Payable Tokens)

The ERC-1363 standard, also known as the payable token standard, is an upgrade to ERC-20 tokens. While ERC-20 tokens can only be sent from one person to another, ERC-1363 tokens can trigger actions in a smart contract immediately after being sent or approved for spending.

For example, if you use one of these tokens to pay for a subscription, the contract can instantly recognize the payment and activate your subscription with no extra steps. This makes the standard useful for quick transactions like buying services, paying invoices, or managing subscriptions, all in one easy step.

Note: Hedera’s system contract functions do not natively support ERC-1363 functionalities on HTS tokens. However, standard ERC-1363 functions can still be implemented within a smart contract and deployed on the network, similar to other EVM-compatible chains.
