TAP on Doge

Protocol documentation for TAP on Dogecoin mainnet: the TAP token protocol from the Trac ecosystem, carried by Doginals inscriptions.

Site: https://bitcoinuniverseio.github.io/tap-on-doge/

TAP on Doge shares its operation names with TAP on Bitcoin and very little else. This documentation stands alone: a reader who has never seen the Bitcoin site can use it, and every place the two chains differ is stated concretely rather than in general terms.

Chain and network	Dogecoin mainnet

Pages

Page	What it covers
Overview	What the protocol is, what Dogecoin changes, the operation list, verified product support
Specification	Numbered rules: envelope, payload, identifiers, tapping, operations, state, activations, invalid conditions
Guide	Worked mint, transfer and batch send; confirmation counts; the mistakes that cost money
Reference	Terminology, confirmation, mempool and reorg semantics, fees, limitations, security, checklist
Test vectors	Accepted and rejected envelopes and payloads, address vectors, state transitions
Validator	Client-side payload validator and confirmation time comparator
Changelog	Document history and Dogecoin protocol activation heights

Operations

Every TAP token operation name is prefixed. A payload carrying p: "tap" with a bare mint or transfer confirms on chain, costs a full Dogecoin fee, and is then indexed by nobody: no TAP indexer recognises the name, and no DRC-20 indexer claims the message because the tag is not drc-20.

• External: token-deploy, token-mint, token-transfer
• Internal: token-send, block-transferables, unblock-transferables, token-trade, token-auth, privilege-auth
• DMT: dmt-deploy, dmt-mint

What Dogecoin changes

Concern	TAP on Bitcoin	TAP on Doge
Block target	10 minutes	1 minute, so six confirmations is about six minutes
Inscription carrier	Taproot witness envelope	Push data in the signature script of input 0
Byte economics	Witness bytes at one quarter weight	No witness, no discount, full rate on every byte
Large content	One reveal transaction	A chain of transactions; an interrupted chain indexes as nothing
Addresses	Bech32m ordinals address	Base58check payment address, version 0x1e or 0x16, case-sensitive
Reorg window	40 to 49 blocks is 7 to 8 hours	40 to 49 blocks is under an hour

A Bitcoin OP_FALSE OP_IF envelope decodes to nothing on Dogecoin: the parser accepts push opcodes only, and OP_IF is not one.

Bitcoin Universe product support

Verified against the protocol registry and the generated capability snapshot in the Bitcoin Universe codebase. Absence means the code does not implement it.

• Wallet: view, send, receive
• Inscribe: mint
• Marketplace: feature gated, external execution. Bitcoin Universe builds and validates the exact Dogecoin transaction; your wallet signs it. Settlement requires at least one confirmation plus the expected protocol state transition in a later authoritative checkpoint.
• Not supported: sell. Recorded reason: TAP on Doge has no executable offer workflow on this marketplace surface.
• Coverage: reported as partial. The pinned reader exposes no Dogecoin mempool feed and publishes no block replacement notifications.
