@tat-protocol/token

Core token model for TAT protocol JWT-like tokens.

Install

npm install @tat-protocol/token

Exports

• Token (default export as Token, plus named export)
• TokenType (FUNGIBLE, TAT)
• Types: Header, Payload
• TokenValidator

Quick Start

import { Token, TokenType } from "@tat-protocol/token";
import { KeySigner } from "@tat-protocol/signers";

const signer = new KeySigner(process.env.ISSUER_SECRET_KEY!);
const issuerPubkey = await signer.getPublicKey();

const token = new Token();
await token.build({
  token_type: TokenType.FUNGIBLE,
  payload: Token.createPayload({
    iss: issuerPubkey,
    amount: 100,
    P2PKlock: process.env.RECIPIENT_PUBKEY,
  }),
});

const signatureHex = await signer.sign(await token.data_to_sign());
const jwt = await token.toJWT(signatureHex);

const restored = await new Token().restore(jwt);
await restored.validate();

Use Cases

• Token issuance and parsing.
• Signature and hash verification.
• Lock checks (P2PKlock, HTLC, timeLock).
• Derived token creation (Token.createDerivedToken).
