How to use UniSat Wallet for Cat20 assets? (Protocol Support)

Understanding Cat20 Protocol Integration

1. UniSat Wallet natively supports the Cat20 protocol, enabling users to store, send, receive, and view Cat20 tokens directly within the interface without requiring third-party extensions.

2. The wallet parses on-chain Cat20 inscription data from Bitcoin’s UTXO set and maps token metadata—including name, symbol, supply, and minting rules—to a human-readable format.

3. Each Cat20 asset is displayed with its unique ticker, current balance, and associated inscription ID, allowing immediate verification of authenticity and provenance.

4. Token transfers comply with Cat20’s native transfer logic: outputs must include valid Cat20 opcodes and adhere to the protocol’s serialization standards for amount encoding and recipient validation.

Importing and Managing Cat20 Assets

1. Upon first launch, UniSat Wallet automatically scans the user’s Bitcoin address for inscribed Cat20 assets using indexed blockchain data from UniSat’s indexer node.

2. Users can manually add unsupported or newly minted Cat20 tokens by entering the token’s ticker or inscription ID in the “Add Token” section under the Assets tab.

3. Balances update in real time as new transactions confirm on-chain; no manual refresh is required due to persistent WebSocket connections to UniSat’s infrastructure.

4. Token metadata—such as decimals, logo URI, and description—is fetched from decentralized storage locations referenced in the inscription’s JSON payload.

Transferring Cat20 Tokens

1. To initiate a transfer, users select a Cat20 asset, enter the recipient’s Bitcoin address, and specify the amount in base units aligned with the token’s declared decimal precision.

2. The wallet constructs a multi-output transaction: one output carries the Cat20 transfer inscription, while others handle change UTXOs and fee allocation according to Bitcoin Core’s standard relay policies.

3. Before broadcasting, UniSat validates that the sender owns sufficient inscribed satoshis tied to the target token and that the destination address has not been blacklisted for malicious activity.

4. Transaction status appears instantly in the Activity feed, showing confirmation progress, block height, and final settlement on the Bitcoin ledger.

Viewing Inscription Details and Ownership History

1. Clicking any Cat20 asset opens a dedicated detail page listing all associated inscriptions, including mint, transfer, and burn events sorted chronologically.

2. Each event displays raw transaction hash, input/output indices, scriptPubKey snippets, and decoded Cat20 opcodes such as CAT20_TRANSFER or CAT20_MINT.

3. Ownership lineage traces back to the genesis inscription, revealing whether the token was minted via an authorized deployer or through a community fork mechanism.

4. Users may export full ownership history as a CSV file containing timestamp, block height, sender, receiver, amount, and inscription ID for external analysis.

Frequently Asked Questions

Q: Can UniSat Wallet hold both BRC-20 and Cat20 tokens simultaneously?A: Yes. UniSat Wallet maintains separate asset registries for BRC-20 and Cat20 protocols, preventing cross-contamination of balances or metadata.

Q: Why does my newly minted Cat20 token not appear immediately after confirmation?A: Indexing latency may cause up to two block delays. UniSat’s indexer processes new blocks sequentially; tokens become visible once the inscription is fully parsed and validated.

Q: Is it possible to delegate Cat20 token management to a hardware wallet via UniSat?A: No. Cat20 operations require inscription-aware signing logic currently unsupported by Ledger or Trezor firmware. All signing occurs client-side within UniSat’s secure execution environment.

Q: Do I need to pay Bitcoin network fees when transferring Cat20 tokens?A: Yes. Every Cat20 transfer is embedded inside a standard Bitcoin transaction, so miners’ fees apply based on transaction size and priority, not token type.
