Sign and Submit Transaction

And you can integrate more things or your D.app features with Transactionsmethods

Aptos

1.1. Single signer transaction

1. Generate transaction usingTransactions

payload = {
    "type": "entry_function_payload",
    "function": "0x1::coin::transfer",
    "type_arguments": ["0x1::aptos_coin::AptosCoin"],
    "arguments": [
        "0x...", // recipient adddress
        "1000", // amount of APT - decimals = 8
    ]
}

rawTransaction = (await fewcha.aptos.generateTransaction(payload)).data;

2. Then Transactions

// Simulate transaction before submission (Optional)
simulateRes = (await fewcha.simulateTransaction(rawTransaction)).data;

// Sign then submit
signedTx = (await fewcha.signTransaction(rawTransaction)).data;
txHash = (await fewcha.aptos.submitTransaction(signedTx)).data;

// Or Sign and submit
txHash = (await fewcha.aptos.signAndSubmitTransaction(rawTransaction)).data;

1.2. Multiple agent transaction

1. Generate transaction usingTransactions

payload = {
    "type": "entry_function_payload",
    "function": "0x3::token::direct_transfer_script",
    "type_arguments": [],
    "arguments": [
        "0x...", // creator address
        "Fewcha Membership", // token collection
        "Member Level 1", // token name
        "0", // property_version
        "1", // amount of token
    ]
}

// List of secondary addresses
// direct_transfer_script
// 2 signers is required (primary and 1 secondary signer)
secondarySigners = [
    "0x...",
]

options = {
    // Primary signer
    // If not specified, the current connected account will be selected
    "sender": "0x..."
    // Other options...
}

rawMultiAgentTransaction = (await 
    fewcha.aptos.generateMultiAgentTransaction(
        payload, 
        secondarySigners, 
        options
    )
).data;

2. Get signatures

primaryPubKey = (await fewcha.account()).data.publicKey;
primarySignedTx = (await 
    fewcha.aptos.signMultiAgentTransaction(
        rawMultiAgentTransaction
    )
).data;

// Change account to the secondary signers specified from the transaction generation step
secondaryPubKey = (await fewcha.account()).data.publicKey;
secondarySignedTx = (await 
    fewcha.aptos.signMultiAgentTransaction(
        rawMultiAgentTransaction
    )
).data;

3. Submit (or simulate) transaction

// Simulate
simulateRes = (await fewcha.aptos.simulateMultiAgentTransaction(
    rawMultiAgentTransaction, // multiAgentTxn
    [options.sender, ...secondarySigners], // addresses
    [primaryPubKey, secondaryPubKey], // pubKeys
)).data;

// Submit
txnHash = (await fewcha.aptos.submitSignedBCSMultiAgentTransaction(
    rawMultiAgentTransaction, // multiAgentTxn
    [options.sender, ...secondarySigners], // addresses
    [primaryPubKey, secondaryPubKey], // pubKeys
    [primarySignedTx, secondarySignedTx] // signatures
)).data;

1.3. Multiple signature transaction

1. Collection account public keys and generate multi-sign address

firstPubKey = (await fewcha.account()).data.publicKey;
secondPubKey = (await fewcha.account()).data.publicKey;
thirdPubKey = (await fewcha.account()).data.publicKey;

const {address, publicKey} = (await fewcha.aptos.getMultiSignAccount(
    [firstPubKey, secondPubKey, thirdPubKey], // list signer publicKeys
    2 // threshold - the number of signature made the transaction valid
)).data;

2. Generate transaction usingTransactions

payload = {
    "type": "entry_function_payload",
    "function": "0x1::coin::transfer",
    "type_arguments": ["0x1::aptos_coin::AptosCoin"],
    "arguments": [
        "0x...", // recipient adddress
        "1000", // amount of APT - decimals = 8
    ]
}

options = {
    // Multi-sign address
    "sender": "0x..."
    // Other options...
}

rawTransaction = (await 
    fewcha.aptos.generateTransaction(
        payload, 
        options
    )
).data;

3. Get at least threshold signatures from the list signers

firstSignature = (await fewcha.aptos.signMultiSignTransaction(rawTransaction)).data;
thirdSignature = (await fewcha.aptos.signMultiSignTransaction(rawTransaction)).data;

4. Submit (or simulate) transaction

// Simulate transaction before submission (Optional)
simulateRes = (await fewcha.simulateTransaction(rawTransaction)).data;

txnHash = (await fewcha.aptos.submitSignedBCSMultiSignTransaction(
    rawTransaction, // Transaction
    [0,2], // Bitmap - 0 is index of first signer, 2 is index of third signer
    publicKey, // multi-sign public key we got from step 1
    [firstSignature, thirdSignature]
)).data;
