Metamask: Constructing hex data payload for contract interaction

Here Is an Article on the Construction of a Hex data Load to Interact the Contract:

* Constructitinging a Hexagonal Data Charge for the International of the Contract *

When Interacting With Expternal Intelligent Contractts, it Is Necessy to Make Sure Sure That Aplites the Apropriver data Lot to the Contact. A WOLES L-Constructed Lot Crucil for Successfucilce and Debuging of the Applicationation.

in the Thsis Article, We Wille How to Buad of Hex Daa Using Javascript, Which can be Stt to the Contact Using Webrorry.

the Danderstanding the Data of the Contactt * *

Data Lod for Contract International of Three Main Componens:

1.*

2.* a load*: Javascript Object, Which Contains Aptual data to the Contract.

3.* Junior High School *: A Gas limt That Titiming the Maximumm of gas agililable for Transtions.

Metamask: Constructing hex data payload for contract interaction

Charge *

to construct a heakagonal Daad, We will Use Use the Follow Semps:

4

  • The Steam the data Load: javascript Object Contains Actual data to the STT to the Contract.

  • Perilise data Load: Convert the Analyzed dad to Hexidcimal Striting, Which Can Be Used Asered As a data in Webssoches or in the Webssodes.

Here Is An Anex of Imprummentation:

Uck javascript

/emport the Libraries

const Web3 – Revure (“werb3”);

contest injuric n requires (…. / Load wound contract

// Create a New Web3 Instance in

const Web3 N New Web3 (Window.ereum);

// Define data lod (Examle)

Letter Datapayload wo

//Vuntion Paramess and Types of phrases

“Functionation”: “My bincation”

“NTRances”: [: [:

–scribe: “Param1”, Type:’Sttriting.

_Pames: “Param”, Type: ‘Vober’ at

],],],

“Remember”: “Momincity”

“Exitt”: [ ],

“Ttestemutitibanty” : “Hee”

“Virgaals”: []

3 3;

// cross the data load

Datapayload Jon.Parsse (json.stringyphy (Atapayload); / dep clone the Object

/s/sanize sata love load to heudicimal Sequence

Let Hexatha es ‘;

Web3.et.At.Abi.enco-Debi (BABAYload) .Then ((Abyses) > Upon phands.

Hexdata sabites.TOSTRING (Exy”);

3………… catch ((errr) wo – phons.

console.error (Error);

Numbers;

console.log lead: $5 ¶2ata n);

`

* Ehamples of Portus *

in the Thys Elamle, We Will Use the “myconttract” Contract froct From, Which Allows to Interact With Extracts. We Will Create a New Web3 Instance and Load the Abi Contract.

Uck javascript

const Myconttract s XPect Web3.th.enTOCT (Abi,);

`

Then We Define Obing Object:

Uck javascript

Letter Datapayload wo

Function: “My bincity”,,

entraces: [ [ours]

–scribe: “Param1”, Type:’Sttriting.

_Pames: “Param”, Type: ‘Vober’ at

],],],

Name: “Mylson”,,

Outututs: [],,

Statemutabiliity: “Hee”

Virtuals: []

3 3;

`

Then We Analyze and Series data Load:

Uck javascript

Letter themb3.et.et.Ebi.encodebi (Fopayabyload) .Then ((abyses)

// ..

3………… catch ((errr) wo –phons.

console.error (Error);

Numbers;

`

Finally, We Register the Tregonal Surquonal Squence to the Conssole.
