Check sync:​

(False -> Done)

xiond status 2>&1 | jq .SyncInfo

Validator Public Key Registration​

Add the configuration below to app.toml if it’s not already present:​

[seda]

# enable-seda-signer enables the SEDA signer.
enable-seda-signer = false

# seda-key-file is the path to the SEDA key file from the node's home directory.
seda-key-file = "config/seda_keys.json"

# allow-unencrypted-seda-keys enables unencrypted use of the SEDA key file.
allow-unencrypted-seda-keys = false

Set app.toml:​

xiond config set app seda.enable-seda-signer true
xiond config set app seda.allow-unencrypted-seda-keys false

Create SEDA key:​

xiond tx pubkey add-seda-keys \
  --from wallet \
  --chain-id seda-1 \
  --gas-prices 10000000000aseda --gas auto --gas-adjustment 2.0 \
  --generate-only

*Carefully back up the value of SEDA_KEYS_ENCRYPTION_KEY, as it is the encryption key used to unlock the SEDA key file. You will then need to add SEDA_KEYS_ENCRYPTION_KEY to your systemd service file so the node can access it during startup.

Add on service:​

Environment="SEDA_KEYS_ENCRYPTION_KEY=your_encryption_key_here"

Restart node​

sudo systemctl daemon-reload
sudo systemctl restart xiond

Submit the transaction:​

xiond tx pubkey add-seda-keys \
  --from wallet \
  --chain-id seda-1 \
  --gas-prices 10000000000aseda --gas auto --gas-adjustment 2.0 \
  --key-file $HOME/.xiond/config/seda_keys.json \
  --key-file-custom-encryption-key

Check status:​

xiond query seda-signer-status

This is the command that ran successfully. ` signer_keys:

  • index: 0 index_name: SEDA_KEY_INDEX_SECP256K1 is_proving_scheme_active: false is_synced: true public_key: 049784a09c85a69d852xxxxxxx validator_address: sedavaloper1lpv7ncf3jpal5gylusfskgr64pgmc7pfa4caum `
