How to submit a blob via Ledger

This gist contains steps to submit a blob via a Ledger hardware wallet.

Steps

Git clone celestia-app
Install celestia-appd
```
make install
```

In one terminal start a celestia-appd node

./scripts/build-run-single-node.sh

Sample output:

Home directory: /var/folders/y0/dd92_x8x4tlf397xstgwfz_c0000gn/T/celestia_app_XXXXXXXXXXXXX.KbLWfNrM

Note the first log line contains a temporary directory.

In a new terminal, export the temporary directory logged in the first terminal.

export CELESTIA_APP_HOME=/var/folders/y0/dd92_x8x4tlf397xstgwfz_c0000gn/T/celestia_app_XXXXXXXXXXXXX.KbLWfNrM

Export the address of the validator that has tokens.

export CELESTIA_APP_ADDRESS=$(./build/celestia-appd keys show validator --keyring-backend test --address --home $CELESTIA_APP_HOME)

Plug in your Ledger and unlock it.
Add an alias to your Ledger's address
```
celestia-appd keys add ledger-1 --ledger --home $CELESTIA_APP_HOME
```
Note this alias exists in the keyring-backend test

Ensure two addresses exist in your keyring-backend

celestia-appd keys list --home $CELESTIA_APP_HOME

Sample output:

- address: celestia1xdc39xr027r78w4eeq6e7e35glgza9ka9rsds2
name: ledger-1
pubkey: '{"@type":"/cosmos.crypto.secp256k1.PubKey","key":"A+u46124WB1YIjLA+Ufriy5aQzcvdM4bily/Y32INEGV"}'
type: ledger
- address: celestia1anmkfa3p5dfe327c2g63jnupegncf5yfad50yn
name: validator
pubkey: '{"@type":"/cosmos.crypto.secp256k1.PubKey","key":"AuTao0TBcgFUl6mhtH6Bz3/jHUBFy+wsar6X0HamMlT4"}'
type: local

Export more aliases

export CELESTIA_VALIDATOR=celestia1anmkfa3p5dfe327c2g63jnupegncf5yfad50yn
export CELESTIA_LEDGER=celestia1xdc39xr027r78w4eeq6e7e35glgza9ka9rsds2

Send tokens from validator address to Ledger address

celestia-appd tx bank send --chain-id private --keyring-backend test --home $CELESTIA_APP_HOME --yes $CELESTIA_VALIDATOR $CELESTIA_LEDGER 100000utia --fees 21000utia

Ensure tokens landed in Ledger address

celestia-appd query bank balances $CELESTIA_LEDGER --home $CELESTIA_APP_HOME

Sample output:

balances:
- amount: "100000"
denom: utia
pagination:
next_key: null
total: "0"

Submit a PayForBlob from the Ledger address

export NAMESPACE_ID=01010101010101010101
export DATA=FF
celestia-appd tx blob PayForBlobs $NAMESPACE_ID $DATA --from $CELESTIA_LEDGER --keyring-backend test --fees 21000utia --yes --chain-id private

Sample output:

Default sign-mode 'direct' not supported by Ledger, using sign-mode 'amino-json'.
