encodeErc1155SingleDeposit

Encodes an ERC-1155 single deposit payload as the ERC-1155 single portal does. This is the inverse of decodeErc1155SingleDeposit, useful for testing.

Usage

import { encodeErc1155SingleDeposit } from "@cartesi/codec";
 
const payload = encodeErc1155SingleDeposit({
  token: "0x67742ff5b2b762503ff0a92738c6fc2ea4a4d182",
  sender: "0x92cc14432c1f82622493abd64d99ea8a3000a7c7",
  tokenId: 42n,
  value: 7n,
  baseLayerData: "0x",
  execLayerData: "0xdeadbeef",
});

Parameters

A Erc1155SingleDeposit object:

• token (Address): token contract.
• sender (Address): token sender.
• tokenId (bigint): identifier of the token being transferred.
• value (bigint): transfer amount.
• baseLayerData (Hex | Uint8Array): additional data to be interpreted by the base layer.
• execLayerData (Hex | Uint8Array): additional data to be interpreted by the execution layer.

And an optional second parameter:

• to ("hex" | "bytes", optional): representation of the encoded data. Defaults to "hex".

Return Type

Hex | Uint8Array: packed-encoded deposit payload, with layout token (20 bytes) ‖ sender (20 bytes) ‖ tokenId (32 bytes) ‖ value (32 bytes) ‖ abi.encode(baseLayerData, execLayerData).

Returns a Hex string by default, or a Uint8Array when to is "bytes".
