Submit and Retrieve a Payload

Submit a payload through an XL1 gateway and retrieve it through typed viewers.

Use a write-capable XL1 gateway for submission and its typed viewer surface for retrieval.

import { PayloadBuilder } from '@xyo-network/sdk'
import { GatewayBuilder } from '@xyo-network/xl1-sdk'

1. Build and validate the application payload.

2. Obtain a write-capable gateway using a public browser-wallet provider or a server-side GatewayBuilder with an application-managed account.

3. Submit through gateway.addPayloadsToChain(...).

4. Retain the returned transaction hash.

5. Retrieve the transaction through gateway.connection.viewer?.transaction.byHash(hash).

6. Validate every application payload body before using it.

Never call raw JSON-RPC method names and never use Ethereum RPC methods against XL1. Use the typed gateway and viewer APIs from @xyo-network/xl1-sdk.
