Constinent Resement = ‘Our-Receiver-Reliver-DRESS’;

Web3.Fromffer (Web3.eth.accoun.Reekving.Reekvingman) .sinctrant transceration ({{{{{{{{ er

by: Keypair.publicey,

To: Recificately,

Data: “Tanassaction of Data”

^)

Alternatively, you use the Web3 instant to interact with:

Javascript

Const Web3 = New Web3 ('..

Web3.Fromffer (Web3.eth.accoun.Reekving.Reekvings) .scre transaction ( {{{ { August
