1
00:00:00.000 --> 00:00:02.720
Every payment leaves a story.

2
00:00:03.200 --> 00:00:05.580
Who you pay, what you spend, and when.

3
00:00:06.180 --> 00:00:07.800
What if you could keep more of that

4
00:00:07.800 --> 00:00:12.120
story private? Tacit brings confidential notes to Bitcoin

5
00:00:12.120 --> 00:00:15.960
and Ethereum. Let's open WELD, walk through the

6
00:00:15.960 --> 00:00:18.580
payment flow, and see exactly where that privacy

7
00:00:18.580 --> 00:00:20.540
begins, and ends.

8
00:00:21.280 --> 00:00:25.060
Start at tacit dot finance slash weld, then

9
00:00:25.060 --> 00:00:28.840
choose Get started. WELD brings private Ether and

10
00:00:28.840 --> 00:00:31.220
Bitcoin payment tools together in one place.

11
00:00:31.680 --> 00:00:34.520
I'm using an unfunded demo identity here.

12
00:00:34.700 --> 00:00:36.700
You'll see the real forms, but I won't

13
00:00:36.700 --> 00:00:38.420
broadcast a deposit or payment.

14
00:00:39.300 --> 00:00:41.500
You can open a Tacit identity with an

15
00:00:41.500 --> 00:00:44.640
Ethereum wallet, a Bitcoin wallet, or a passkey.

16
00:00:44.640 --> 00:00:47.180
With Ethereum, you sign a message.

17
00:00:47.540 --> 00:00:50.300
That's different from sending a transaction, so opening

18
00:00:50.300 --> 00:00:51.920
the identity doesn't spend gas.

19
00:00:52.380 --> 00:00:55.700
That signature matters: it controls the Tacit identity.

20
00:00:56.300 --> 00:00:58.320
Check that you're on the official app, and

21
00:00:58.320 --> 00:01:00.980
keep your wallet or passkey recovery method safe.

22
00:01:01.620 --> 00:01:05.020
For this walkthrough, open Private Ether and choose

23
00:01:05.020 --> 00:01:08.660
Tacit pool. The neighboring On this device option

24
00:01:08.660 --> 00:01:10.600
uses a different pool, so don't mix up

25
00:01:10.600 --> 00:01:14.540
their instructions. Choose Make private, enter an amount,

26
00:01:14.700 --> 00:01:17.780
and review the funding source, quote, and fees.

27
00:01:18.600 --> 00:01:21.540
This route wraps Ether into confidential tETH notes.

28
00:01:22.060 --> 00:01:24.680
Confirm the deposit in your wallet, then wait

29
00:01:24.680 --> 00:01:27.500
for confirmation and settlement before using the private

30
00:01:27.500 --> 00:01:27.920
balance.

31
00:01:29.060 --> 00:01:31.000
So, what's a note?

32
00:01:31.920 --> 00:01:33.920
Think of it as a private claim to

33
00:01:33.920 --> 00:01:37.760
funds. Spending consumes valid notes and creates new

34
00:01:37.760 --> 00:01:40.840
ones. A zero knowledge proof checks the rules

35
00:01:40.840 --> 00:01:42.860
without exposing the hidden values.

36
00:01:43.620 --> 00:01:47.660
Tacit's general pool uses SP1 proofs to reconcile

37
00:01:47.660 --> 00:01:49.360
Bitcoin and Ethereum state.

38
00:01:50.080 --> 00:01:52.860
The animation is a simplified model of verification.

39
00:01:53.540 --> 00:01:56.020
It isn't a transaction, and it doesn't mean

40
00:01:56.020 --> 00:01:58.540
every Tacit pool uses the same proof system.

41
00:01:59.620 --> 00:02:02.060
Back in the Tacit pool, choose Send.

42
00:02:02.060 --> 00:02:05.620
Enter the recipient's Tacit address or a supported

43
00:02:05.620 --> 00:02:08.900
name. If a name resolves, check the recipient

44
00:02:08.900 --> 00:02:10.620
it points to before you continue.

45
00:02:11.100 --> 00:02:13.380
Then review the amount and relay fees.

46
00:02:14.100 --> 00:02:16.700
In this route, the recipient claims the payment

47
00:02:16.700 --> 00:02:17.780
in their Tacit wallet.

48
00:02:18.100 --> 00:02:20.200
The claim fee comes out of that payment,

49
00:02:20.320 --> 00:02:22.320
so factor it into what they'll receive.

50
00:02:23.500 --> 00:02:25.820
Want to explore the Bitcoin side first?

51
00:02:26.140 --> 00:02:29.080
Open Secret Sats and select signet.

52
00:02:29.080 --> 00:02:33.300
Use Get signet sats, then buy and shield

53
00:02:33.300 --> 00:02:39.800
test cBTC. After that, explore Pay privately, Receive,

54
00:02:40.100 --> 00:02:44.400
and Exit. These specialized pool spends are proved

55
00:02:44.400 --> 00:02:47.480
in your browser. Keep the test network label

56
00:02:47.480 --> 00:02:51.740
in view. Signet sats are test coins, and

57
00:02:51.740 --> 00:02:55.480
signet cBTC is a test token with no

58
00:02:55.480 --> 00:02:56.460
Bitcoin backing.

59
00:02:57.320 --> 00:02:58.660
Here's the key limit:

60
00:02:59.160 --> 00:03:00.740
privacy has a boundary.

61
00:03:01.520 --> 00:03:05.420
Inside the confidential pool, amounts, consumed notes, and

62
00:03:05.420 --> 00:03:07.200
stealth recipients can stay hidden.

63
00:03:07.840 --> 00:03:10.640
Deposits and withdrawals remain public chain events.

64
00:03:11.260 --> 00:03:14.380
Bitcoin addresses and the public transaction graph don't

65
00:03:14.380 --> 00:03:17.280
disappear either. So private payments don't make your

66
00:03:17.280 --> 00:03:18.980
entire wallet history anonymous.

67
00:03:19.440 --> 00:03:22.020
Read the security details for the pool and

68
00:03:22.020 --> 00:03:23.240
route you're actually using.

69
00:03:23.940 --> 00:03:26.740
Before you send, check four things:

70
00:03:27.200 --> 00:03:30.660
the app, the pool, the recipient, and the

71
00:03:30.660 --> 00:03:33.080
fees. Wait for your deposit to settle.

72
00:03:33.540 --> 00:03:35.980
If a balance lookup fails, retry it.

73
00:03:36.240 --> 00:03:38.440
An unavailable balance doesn't mean zero.

74
00:03:38.880 --> 00:03:41.400
Keep a recovery method you can use, and

75
00:03:41.400 --> 00:03:43.620
practice on signet if you're still learning the

76
00:03:43.620 --> 00:03:43.920
flow.

77
00:03:44.580 --> 00:03:46.760
Now you've seen how the pieces fit:

78
00:03:47.240 --> 00:03:50.600
a wallet identity, confidential notes, and a route

79
00:03:50.600 --> 00:03:52.820
you can follow. Ready to explore?

80
00:03:53.320 --> 00:03:55.620
Open the companion guide for the app links,

81
00:03:55.760 --> 00:03:57.980
official docs, and every step we covered.

82
00:03:58.480 --> 00:04:00.240
Start on signet if you're learning.

83
00:04:00.920 --> 00:04:03.680
Open. Shield. Understand.

84
00:04:04.540 --> 00:04:07.980
And a final shout-out to Ross, Tacit's creator,

85
00:04:08.300 --> 00:04:11.140
and to XNS for its work on human-readable

86
00:04:11.140 --> 00:04:14.540
wallet names. Their profiles and project links are

87
00:04:14.540 --> 00:04:16.480
in the guide. Thanks for watching.
