Sending Transactions


The undeniable but fundamental activity in the web3 universe is Sending Transactions. This action can invoke simple token transfers, the creation of new smart contracts, or change the status of the blockchain in a variety of ways. Sending Transactions can be largely divided into two stages: transaction signing and transaction sending, and WELLDONE Wallet can sign and send transactions at once using the dapp:signAndSendTransaction method.

CHAIN NAME and HEX_STRING_TX_DATA are two parameters for dapp:signAndSendTransaction. CHAIN_NAME is the name of the network to which you wish to add, and HEX_STRING_TX_DATA is the value of converting the transaction to a HEX string type. Because a transaction format differs by networks, WELLDONE Wallet executes the transaction by taking the input argument in hex string type then translate it to compatible to the targeted network.


You can put the transaction objects as they are in EVM networks.

| 'sui';
type HEX_STRING_TX_DATA = 'string';

const response = await window.dapp.request(CHAIN_NAME, {
method: 'dapp:signAndSendTransaction',

There is a difference in how to construct HEX_STRING_TX_DATA since each chain's transaction format is different, even though all chains use the same method dapp:signAndSendTransaction. Each chain-specific section below provides details on how to send requests by the chain with simple token transfer transaction example.
