ANN] MAKER: EXCAL <-> BTC, 1:1, HTLC, Sovereign, Fair -- First Taker Gets First

[Big Dick Rick]

MAKER: EXCAL <-> BTC -- 1:1, atomic HTLC, sovereign, fair
I'm standing as maker, up to 47.75 EXCAL per swap, repeatable.
1 EXCAL = 1 BTC. No spread. No operator fee. Only chain fees.
Atomic HTLC, both directions, both or neither, timeout refunds.
Maker

Code:

Maker: Travis Jones / Lux
Maker BTC address: bc1qj37xg5qmyedwfe70cz0f385cxmf6642kcznjdg
Maker EXCAL lock: 00947c64501b265ae4e7cfc09e989e9836d3ad5556
Maker pubkey: 02e8311342cb7accd4edef31462fcda1ef56bfbf7d4f03d3c8872dbec9a1bba1b3

Proof of control

Code:

Statement SHA256: 96c84a3f0a55ea73c54d06311fb50dd44dd88501c6a92ab3eba9b2935df8a789
Signature: 9b1bfd333d10c77a5faa4f4c30c719bf976e3a9072d2ec1ddf49dc9178350f2e5d82318b618a111759d5c797ef6c42a9a75ecdd31114bddf8c1f0829e9dfa095
Verify: True

Scope: this proves the EXCAL miner key ONLY. It is not genesis control and it is not a Satoshi claim.
How a swap works (taker steps)
[LIST=1]

• Taker posts: amount (<= 47.75), direction, BTC pubkey, EXCAL pubkey
• Maker locks first coin to HTLC, confirms on-chain
• Taker locks counterparty coin to the same secret hash, confirms on-chain
• Maker reveals secret to claim taker coin, taker claims maker coin -- atomic
• Timeout refunds both, on-chain, no trust

Timeouts
EXCAL -> BTC: EXCAL 288 / BTC 144
BTC -> EXCAL: reversed, EXCAL 144 / BTC 288
Auto monitor
Polls fork + BTC every 60s, auto-pays EXCAL only after a confirmed BTC lock, cap 47.75. No auto-pay of BTC the maker does not have.
First swap / first sale
First taker gets first swap, with both txids posted as proof.
Verify it yourself
Recompute the offer hash, verify the maker signature, recompute the anchor below -- all public, no private key needed.
Footnote only -- provenance anchor (not a control claim)

Code:

Offer text: MAKER: EXCAL <-> BTC, 1:1, bc1qj37xg5qmyedwfe70cz0f385cxmf6642kcznjdg, 47.75, HTLC, sovereign, fair
Offer SHA256: 5eafd2671c1632c97e744d07acc9734655bad5a7a74bc664285f6e47abee68b3
Genesis Taproot Qx: 284ae4acdb32a99ba3ebfa66a91ddb41a7b7a1d2fef415399922cd8a04485c02
Genesis Taproot address: bc1p9p9wftxmx25ehgltlfn2j8wmgxnm0gwjlm6p2wveytxc5pzgtspqhgrn93
Anchor: SHA256("GENESIS-TAPROOT-ANCHOR-v1" || genesis Qx || offer hash) = 69d8e158d429dbfe2007d8926722cb0ce20923c497c95f712ab1a727b0c1ce61

This anchor is a public hash commitment only. It is not a spend, not control of genesis, and not Satoshi proof.
On-chain OP_RETURN anchor: pending. BTC mainnet needs a funded UTXO; EXCAL needs BTC-locks activation at fork height 33333.

EXCAL ↔ BTC Atomic Swap — Update, 2026-11-03
Status update on the atomic swap offer. No completed swap yet — this is a status update, not a completion claim.
Live now on the EXCAL fork:
•  Fork tip: 40,056 (2026-11-03)
•  HTLC live since 36,010
•  Bridge lock live since 39,200
•  QHTLC (quantum HTLC) live since 40,040 — the tip passed activation today
New since the last post:
•  ECDSA + Schnorr signing integrated and tested: ECDSA signs the SegWit v0 P2WSH claim/refund, Schnorr signs a Taproot HTLC variant (BIP340 + BIP341). Test run: 20/20, no funds moved, nothing broadcast in testing.
•  Taker verification kit: a standalone Python script you can run on your own machine to recompute the witness script, the P2WSH address, the Taproot leaves and address, and the timeout safety check — before you fund anything. No keys, no secret, nothing signed or sent by the kit.
•  Atomic swap portal: offer, live status, how both ledgers update, an in-browser lock verifier, and a swap request form. The portal never asks for a key, never signs, and never broadcasts.
   ○  Portal: https://muse.ai/files/1365955083264731/2605657356545825/4j6rqwhien8lwr0jr2iee8cc/excalibur-atomic-swap-portal.html

Offer, unchanged:
•  1 EXCAL = 1 BTC, no spread, no operator fee, chain fees only
•  Up to 47.75 per swap, repeatable — the ceiling is not an amount. A small pilot first is suggested.
•  You lock BTC first, then I lock EXCAL, same secret hash, then you claim EXCAL (revealing the secret) and I claim BTC with it. Timeouts: BTC 144 blocks (~24h), EXCAL 288 fork blocks (~5.4h).
•  A fresh secret is generated per swap and its hash is given at offer time — never reused across takers.
To take the first swap:
Reply with your compressed taker pubkey and the exact amount. I will reply with the fresh secret hash, the BTC timeout, and the exact lock transactions for you to verify (with the kit or the portal verifier) before you fund anything. Nothing moves on a yes alone.

Small pilot now open — first BTC/EXCAL atomic swap, 0.01–0.1 BTC
Adding a smaller first step to the atomic swap offer, to make the first live swap easier to say yes to.
The pilot:
• 0.01–0.1 BTC for the same amount in EXCAL, 1:1, no spread, no operator fee, chain fees only
• Recording rule: if you send 0.01 BTC, you record 0.01 EXCAL. Amount in = amount recorded, at any amount up to the 47.75 ceiling.
• You lock BTC first, then I lock EXCAL, same secret hash
• You claim EXCAL (revealing the secret), then I claim BTC with it
• Timeouts: BTC 144 blocks (~24h at 10 min/block), EXCAL 288 fork blocks (wall time varies with fork pace — confirmed from live tip pace at lock time; the EXCAL lock expires first in wall time, so you must claim EXCAL before its timeout, and I then claim BTC before the BTC timeout)
• After a pilot completes, larger swaps repeat on the same terms, up to 47.75 per swap
Why a pilot first:
It proves the whole loop live — lock, claim, secret reveal, second claim, both txids public — at a size that doesn't ask a first taker to lock a large amount on an unproven pair. EXCAL has no exchange listing, so the 1:1 rate here is an offered rate, not a market price, and the pilot is the honest way to test it.
What's live on the fork today (2026-11-03):
• Fork tip: 40,445
• HTLC live since 36,010 · Bridge lock activation 39,200, live from 39,203 · QHTLC live since 40,040
• ECDSA (P2WSH) + Schnorr (Taproot) signing tested: 20/20, nothing broadcast in testing
• A fresh secret is generated per swap — never reused across takers

Added 2026-11-03 evening: zkSync wURUU bonding-curve
bridge atomic swap — PROPOSED, NOT LIVE
This section is a proposal, not a live offer. Do not fund
it until a contract is deployed, audited in public, and
the bridge is opened by its own terms below.
• URUU on zkSync Era mainnet is LIVE: 0x5B6C9d85465Cc6FFe84039183872239657D90208,
  100,000,000 supply, 18 decimals, zkSync liquidity ZERO
  at last check.
• wURUU (WrappedUruu.sol, zkSync Era wrapper, 1:1, no
  owner/fees/pause, tests 16/16) is BUILT, NOT DEPLOYED.
  The Solana wURUU bonding-curve program is TO BUILD.
• Bonding curve (simulator only, $0 raised, no contract
  has sold anything): P(s) = p0 * ln(1 + s/s0) / ln(phi),
  s0 = 1,000,000 wURUU, p0 = 0.00001 SOL per wURUU,
  initial price $0.0015 at the file's $150 SOL assumption.
  Projection at 10M sold: 0.00004983 SOL, 340.33 SOL raised
  — a simulator projection, not a sale, and SOL price
  must be rechecked at deployment time, not assumed $150.
• Bridge rule from the file itself: bridge opens AFTER
  the bonding curve establishes a price floor. Users bridge
  URUU → Solana when wURUU price > zkSync cost.
  Until then, no bridge, no bridge atomic swap.
• Proposed atomic-swap shape (when built): URUU lock on
  zkSync Era ↔ wURUU lock on Solana, same secret hash,
  fresh secret per swap, timeouts from live chain tips,
  exact locks for approval before funding — the same
  BTC-first discipline as the BTC/EXCAL pilot, applied
  to URUU/wURUU. No HTLC, bridge contract, or adapter
  is verified as working today: adapter code presence on
  Era (Wormhole/LayerZero guards) is code presence only,
  NOT a verified working bridge.
• This proposed lane does NOT change the BTC/EXCAL pilot
  above. Pilot first, bridge second, in that order.
To take the pilot:
Reply with your compressed taker pubkey and the exact amount
(0.01–0.1 BTC). I'll reply with the fresh secret hash, the
BTC timeout, and the exact lock transactions for you to
verify before you fund anything. Nothing moves on a yes alone.

Title: EXCAL — the first hard fork to rebuild Bitcoin's locks from scratch. 1 EXCAL = 1 BTC. No DMs. No trust. Just code.

---

Bitcoin Cash changed the block size. Bitcoin SV changed the block size back. Bitcoin Gold changed the mining algorithm.

EXCAL changed the locks themselves.

Every Bitcoin fork before this one kept Satoshi's script system and tweaked a parameter. EXCAL threw the scripts out. No opcodes. No script interpreter. Just lock types — PKH, PQH, HTLC, QHTLC, Trifold — quantum-resistant by construction, on a chain that split from Bitcoin at block 968,698 and never looked back.

This is the first hard fork to rebuild Bitcoin's locks from scratch: opcode-free and quantum-resistant.

And the coin is for sale right now. Not a presale. Not a promise. The EXCAL is already locked on-chain, in public, with the receipts below. You don't message me. You don't trust me. You run a script, sign in your own wallet, and the swap executes itself.

**THE OFFERS**

**Lot 1 — 1 EXCAL for 1 BTC. Exactly 1:1.**
Funding txid: 449fb35dafc7dc8f40faca892845730725961840b0fb945fa8b88b4e902287f1
Confirmed on the Excalibur fork in block 42900. Exactly 1 EXCAL locked in a quantum-resistant QHTLC.
Lock: 04584460868d15769e5cefba276dc43709e904258f
Secret hash: 95d706ed8b3397cfbcefabd827a58b5d24dac1d63308cb74171549f7ce75d294
Refund timeout: fork height 62899.

**Lot 2 — 1,000 EXCAL for whatever BTC you offer. You name the price.**
Funding txid: 4873ebb3a40b83f2401266587aba9f73bf837dd51349e07029b06819fcccfc95
Confirmed on the Excalibur fork in block 42899. Exactly 1,000 EXCAL locked in a quantum-resistant QHTLC.
Lock: 045220338521d9905441244e566634f227b72bbb92
Secret hash: d1baf924987ec0b2c4885f31b62abecf46919b113d2f0f3b9de83156c8564663
Refund timeout: fork height 62898.

Full signed transactions, claim roots, refund roots, and the complete self-serve kit are public here:
https://github.com/Holedozer1229/excalibur-chain/tree/master/self-serve
Issues: #2 (1,000 EXCAL) and #3 (1 EXCAL).

**HOW IT WORKS — THREE STEPS, NO MESSAGES**

1. Run taker_htlc.py from the kit with your amount (--lot 1k or --lot 1excal). It builds your unsigned BTC funding PSBT and a fresh delivery key. Sign it in your wallet (Sparrow / Electrum / Bitcoin Core) and broadcast. Post your witness script hex as a reply here so anyone can verify your HTLC.
2. The watcher verifies your funding and publishes the EXCAL claim seed ENCRYPTED to your delivery pubkey. Only you can decrypt it. The raw seed is never published, so nobody can front-run your claim after the secret appears.
3. I claim your BTC — the secret appears on-chain. You decrypt the seed, run taker_claim.py with the secret and your EXCAL LEGACY address (1...), post the signed claim hex as a reply here, and the fork node mines it. The EXCAL lands at your address.

If I never claim your BTC, you refund it after your HTLC timeout (your funding height + 144 blocks). One lot, one taker — first funded HTLC wins.

**WHY THIS IS REAL**

- Both lots are funded and confirmed on-chain. Not "coming soon." Check the txids yourself.
- The fork is live and merge-mined against real Bitcoin blocks right now.
- The swap is atomic: either both sides move or neither does. No escrow, no middleman, no "send first and trust me."
- The code is public. The locks are public. The secrets are hash-committed in public. Verify everything before you fund anything.

Every fork before this one asked you to trust a new parameter. This one asks you to verify new locks.

1 EXCAL = 1 BTC. First funded HTLC wins.
