Hi Devs,

As promised, a Sapio Tutorial. In this tutorial we'll walk through how to
use the Sapio CLI to generate contracts and play with them on the network.
We'll use a congestion control tree because it's very simple! We will walk
through this step-by-step during the meeting today.

-1. Install JQ (json manipulating tool) if you don't have it / other things
needed to run a bitcoin node.
0. Set up a node as described above.  You'll likely want settings like this
in your bitcoin.conf too:
[signet]
# generate this yourself

rpcauth=3Dgenerateme:fromtherpcauth.pyfile
txindex=3D1
signetchallenge=3D512102946e8ba8eca597194e7ed90377d9bbebc5d17a9609ab3e35e70=
6612ee882759351ae

rpcport=3D18332
rpcworkqueue=3D1000
fallbackfee=3D0.0002

Get coins https://faucet.ctvsignet.com/ / DM me

1. Follow the install instructions on
https://learn.sapio-lang.org/ch01-01-installation.html You can skip the the
sapio-studio part / pod part and just do the Local Quickstart up until
"Instantiate a contract from the plugin". You'll also want to run *cargo
build --release* from the root directory to build the sapio-cli.


2. Open up the site https://rjsf-team.github.io/react-jsonschema-form/
3. Run *sapio-cli contract api --file
plugin-example/target/wasm32-unknown-unknown/debug/sapio_wasm_plugin_exampl=
e.wasm*
4. Copy the resulting JSON into the RJSF site
5. Fill out the form as you wish. You should see a JSON like
{
"context": {
"amount": 3,
"network": "Signet",
"effects": {
"effects": {}
}
},
"arguments": {
"TreePay": {
"fee_sats_per_tx": 1000,
"participants": [
{
"address": "tb1pwqchwp3zur2ewuqsvg0mcl34pmcyxzqn9x8vn0p5a4hzckmujqpqp2dlma"=
,
"amount": 1
},
{
"address": "tb1pwqchwp3zur2ewuqsvg0mcl34pmcyxzqn9x8vn0p5a4hzckmujqpqp2dlma"=
,
"amount": 1
}
],
"radix": 2
}
}
}

You may have to delete some extra fields (that site is a little buggy).

Optionally, just modify the JSON above directly.

6. Copy the JSON and paste it into a file ARGS.json
7. Find your sapio-cli config file (mine is at
~/.config/sapio-cli/config.json). Modify it to look like (enter your
rpcauth credentials):
{
 "main": null,
 "testnet": null,
 "signet": {
   "active": true,
   "api_node": {
     "url": "http://0.0.0.0:18332",
     "auth": {
       "UserPass": [
         "YOUR RPC NAME",
         "YOUR PASSWORD HERE"
       ]
     }
   },
   "emulator_nodes": {
     "enabled": false,
     "emulators": [],
     "threshold": 1
   },
   "plugin_map": {}
 },
 "regtest": null
}

8. Create a contract template:
*cat ARGS.json| ./target/release/sapio-cli contract create  --file
plugin-example/target/wasm32-unknown-unknown/debug/sapio_wasm_plugin_exampl=
e.wasm
 | jq > UNBOUND.json*
9. Get a proposed funding & binding of the template to that utxo:

*cat UNBOUND.json| ./target/release/sapio-cli contract bind | jq >
BOUND.json*
10. Finalize the funding tx:

*cat BOUND.json | jq ".program[\"funding\"].txs[0].linked_psbt.psbt" |
xargs echo | xargs -I% ./bitcoin-cli -signet utxoupdatepsbt % |  xargs -I%
./bitcoin-cli -signet walletprocesspsbt % | jq ".psbt" | xargs -I%
./bitcoin-cli -signet finalizepsbt % | jq ".hex"*

11. Review the hex transaction/make sure you want this contract... and then
send to network:



*./bitcoin-cli -signet sendrawtransaction
020000000001015e69106b2eb00d668d945101ed3c0102cf35aba738ee6520fc2603bd60a87=
2ea0000000000feffffff02e8c5eb0b000000002200203d00d88fd664cbfaf8a1296d3f7176=
25595d2980976bbf4feeb10ab090180ccdcb3faefd020000002251208f7e5e50ce7f65debe0=
36a90641a7e4d719d65d621426fd6589e5ec1c5969e200140a348a8711cb389bdb3cc0b1050=
961e588bb42cb5eb429dd0a415b7b9c712748fa4d5dfe2bb9c4dc48b31a7e3d1a66d9104bbb=
5936698f8ef8a92ac27a650663500000000*


12. Send the other transactions:

*cat BOUND.json| jq .program | jq ".[].txs[0].linked_psbt.psbt" | xargs -I%
./target/release/sapio-cli psbt finalize --psbt %  | xargs -I%
./bitcoin-cli -signet sendrawtransaction %*



Now what?

- Maybe load up the Sapio Studio and try it through the GUI?
- Modify the congestion control tree code and recompile it?
- How big of a tree can you make (I did about 6000 last night)?
- Try out other contracts?
