1. Layer Forge

$3

User sends 2551 to forge and selects layers to be moved

``
import { Forge } from "@ethercards/ec-util";
const forge = new Forge();
const result = forge.encodeLayerTransfer(2550, 2551, false, false, false, true, true);

// 0x0001000109f609f734313033383364343036
`

$3

0x0001000109f609f734313033383364343036

`
import { Forge } from "@ethercards/ec-util";
const forge = new Forge();
const data = forge.decodeLayerTransfer("0x0001000109f609f734313033383364343036");

// decoded: {
// version: 1,
// method_id: 1,
// dstTokenId: 2550,
// srcTokenId: 2551,
// layer1: false,
// layer2: false,
// layer3: false,
// layer4: true,
// layer5: true
// }
`

2. Traits Registry

`
import { Registry } from "@ethercards/ec-util";

const onChainUint8Result = [3, 16, 255]; // 96 traits
const registry = new Registry();
const traits = registry.decodeTraits(onChainUint8Result);

traitData.set(data);
