Install And Configure

Install Switchboard on a machine that can hold local signing material. A Switchboard app repository should contain app code and project config, not live credentials.

Requirements​

  • Node.js 22 or newer for the CLI.
  • Access values from PROOF for your deployment environment.
  • A funded Acurast mainnet account for deployment fees.
  • A funded Polkadot Hub account with an accepted quote asset.
  • A small Hub native balance for payment transactions.
  • Permission to create DNS records for any customer hostname you attach.

Install The PROOF CLI​

npm install --global @proof-computer/proof-cli
proof plugins install @proof-computer/proof-cli-switchboard
proof switchboard --help

All public examples use the proof switchboard ... command group.

Use The Wizard​

Switchboard contexts store environment variable names, not secret values. Keep the values in your shell, password manager, or local secret file.

proof switchboard context add mainnet

The wizard prompts for:

  • Acurast seed environment variable
  • expected Acurast address environment variable
  • Polkadot payment address and signer
  • optional Ledger payment signer settings
  • soft balance checks

The wizard refuses to overwrite an existing context. Edit an existing context with context set:

proof switchboard context set mainnet \
  --use \
  --acurast-seed-env ACURAST_MAINNET_SEED \
  --acurast-address-env ACURAST_MAINNET_ADDRESS \
  --polkadot-address-env POLKADOT_ADDRESS \
  --polkadot-seed-env POLKADOT_SEED

Ledger Payment Signing​

Ledger signing is scoped to Hub funding, claim, and refund transactions. It does not replace Acurast deployment signing.

proof switchboard context set ledger \
  --use \
  --polkadot-signer ledger \
  --polkadot-address '<ledger polkadot address>' \
  --ledger-account 0 \
  --ledger-address-index 0 \
  --ledger-metadata-chain-id '<zondax chain id>' \
  --acurast-seed-env ACURAST_MAINNET_SEED \
  --acurast-address-env ACURAST_MAINNET_ADDRESS

Use --ledger-mode generic for the Polkadot Generic app. The legacy Statemint path is available with --ledger-mode legacy --ledger-chain statemint.

Check The Active Context​

proof switchboard context current
proof switchboard context list
proof switchboard preflight --quote

Run preflight after changing credentials, funding accounts, or the selected context.
