Bitcoin Mainnet
DUST-20 — each SATDUST locks 546 sats in a UTXO on L1.
More supply only after milestones and holder votes. Contributors whitelist mints first.
DUST-20 shapes a UTXO-native token: each accepted mint binds the asset to a fixed carrier of real sats. That SATDUST is swap inventory on Bitcoin L1 — spendable liquidity, not an empty indexer balance.
At mint, the BTC that backs the token must actually sit in the same output that carries it — 546 sats locked in that UTXO, not an indexer IOU. Afterward, moving SATDUST is mostly a normal Bitcoin spend of that UTXO, not a separate transfer inscription.
L1 swap architecture
The pool holds BTC and SATDUST carrier UTXOs under a declared control path. Swaps spend and recreate those outputs atomically — inventory stays on L1, visible in the UTXO set.
Price moves with every swap. A constant-product style curve (reserves stay on x·y = k) sets how much you get — the rule is fixed, the quote is not.
Parallel intents contend for the same pool UTXOs. Reservation, conflict drop, and retry keep fills serializable on L1 without freezing the whole market on one mempool race.
Mint path
Bitcoin mainnet tx │ ▼ Inscription (commit → reveal) │ dust-20 mint JSON ▼ Mint UTXO │ value == declared sats │ inscription offset == 0 ▼ Indexer accept → SATDUST + spendable sats ▼ Transfer = spend that UTXO
Deploy
SATDUST: 54,600 × 546 sats = 29,811,600 sats total.

Transfer
No separate transfer inscription — and no op:transfer. You spend the carrier UTXO like any other Bitcoin output; the token moves with those sats. Mint price only on /mint. Swap migrates when the first mint batch completes.
