Docs Issues / Improvements

[qlp]

below a list of improvements I found reading https://docs.union.build

✅ issue 1-9 are about https://docs.union.build/integrations/ucs01/cosmwasm
(used a fresh orbstack ubuntu arm image to review the instructions)

** ✅ issue 1: error: linker cc not found**
solution
$ sudo apt update
$ sudo apt install build-essential

** ✅ issue 2: need nightly rust**
$ rustup override set nightly-2024-10-11
$ rustup component add rust-src --toolchain nightly-2024-10-11-aarch64-unknown-linux-gnu

** ✅ issue 3: unused import in example**
use std::collections::BTreeMap;

** ✅ issue 4: missing wasm-opt**
$ cargo install wasm-pack
$ cargo install wasm-opt

✅ issue 5: no instruction to set WALLET_ADDRESS

✅ issue 6 rg only prints code_id, not the context. add -C 1 to the rg command to show line before and after
$ ./uniond query tx $DEPLOY_TX_HASH --node https://rpc.testnet-8.union.build:443 | rg -C 1 "code_id"

✅ issue 7 payload cannot be consumed by contract. changed to

{
  "transfer": {
    "receiver": "d8da6bf26964af9d7eed9e03e53415d37aa96045",
    "memo": "hello friend",
    "channel": "channel-86"
  }
}

✅ issue 8: use ‘not library feature’ recommendation in example 
recommended here: https://docs.cosmwasm.com/core/conventions/library-feature
#[cfg_attr(not(feature = "library"), entry_point)]

✅ issue 9: us jq to extract data from responses, like explained on https://docs.cosmwasm.com/wasmd/getting-started/cli
jq -r '.events[]| select(.type=="store_code").attributes[]| select(.key=="code_id").value'

issue 10: filling: https://docs.union.build/protocol/channels/ucs03-zkgm/#open-filling
maybe introduce / link ot the concept of filling

issue 11: about the sequence diagrams
a more detailed view (that includes all the messages and the role of the relayer) would be nice

issue 12: conditional light client: https://docs.union.build/concepts/conditional-light-clients/

• explain l1a/l1b
• a sequence diagram would really help

issue 13: https://docs.union.build/infrastructure/node-operators/getting-started/
repo is not private anymore?
maybe remove this whole ‘infrastructure’ section as it overlaps ‘joining the testnet’?

issue 14: https://docs.union.build/integrations/cometbft/connecting-a-cometbft-chain/
Title is a bit misleading: maybe Connecting New Cosmos Chain?
