How to Burn PNDO for pALEO?

PNDO's utility explained

As there is no web interface to burn PNDO yet, the burn function must be executed directly from the Leo Demo DApp. Here is the step-by-step guide to do so.

Step 1: Open https://demo.leo.app/execute, and connect your wallet

Step 2: Fill the required fields of the form

Program ID: pondo_protocol_token.aleo

Function Name: burn_public

Inputs: (One input per line)

YOUR_ADDRESS (It must be the same as the wallet address connected to the dApp) PNDO_BURNT_AMOUNT (Postfixed with u128, as an integer with 6 digits precision, for instance 23.5 PNDO would be represented by 23500000u128) WITHDRAWN_PALEO_AMOUNT (Postfixed with u128, as an integer with 6 digits precision, for instance 123.456 ALEO would be represented by 123456000u128, see next section to learn how to determine this amount)

Fee: 346053 (Network fees, ~0.35 ALEO)

Step 3: Review and Confirm the Transaction in your Wallet

How to determine the withdrawn pALEO amount?

Let's say you are trying to burn a PNDO token amount N, you then need to determine what is the associated withdrawn pALEO amount: A. Let's understand how to compute A from N.

Step 1: Retrieve B, the pALEO balance of Pondo Contract

Open the following link: https://api.explorer.provable.com/v1/mainnet/program/token_registry.aleo/mapping/authorized_balances/3242288718229738787948769588602675310170924869859109695547161313477376112745field

B is the integer between balance: and the following u128, here 57062905199.

Step 2: Retrieve S, the PNDO current supply

Open the following link: https://api.explorer.provable.com/v1/mainnet/program/token_registry.aleo/mapping/registered_tokens/1751493913335802797273486270793650302076377624243810059080883537084141842601field

S is the integer between supply: and the following u128, here 57062905199.

You can then obtain the pALEO amount A you will get for burning N PNDO tokens:

$$A=\frac{N\cdot B}{S}$$
