Mainnet config audit + env-var diff ​

Last updated 2026-06-16. Pre-launch audit of scripts/localnet.sh and the per-service env vars needed when flipping testnet → mainnet.

Part 1 — scripts/localnet.sh audit ​

Run NETWORK=mainnet scripts/localnet.sh to build the mainnet genesis. Below is what the script branches on, what's hard-coded the same for both networks, and what to override.

What the mainnet branch already gets right ​

Governance periodsWas wrong: SDK defaults are 2d voting / 2d deposit / 10⁷ base-unit deposit, not 14d. Mainnet genesis shipped with them. Fixed on chain by MsgUpdateParams (see scripts/mainnet/gov-params-update.md); localnet.sh now sets 14d / 14d / 1d expedited / 10,000 SNCT / 50,000 SNCT for mainnetexplicit mainnet block in localnet.sh

What's the same on both networks (intentional — verify these are still right for mainnet) ​

What needs operator decisions before mainnet genesis ​

DecisionDefault if you don't setRecommended for mainnet
Single genesis address vs splitSingle $VAL_KEY gets full 1BUse post-genesis GenesisSplit Foundry script to distribute 1B → 3 Safes after genesis is built (testnet pattern)

Genesis build command for Day 0 ​

bash
NETWORK=mainnet \
CHAIN_ID=sanect_7628-1 \
MIN_GAS_PRICE=10000000000.000000000000000000 \
BASE_FEE=10000000000.000000000000000000 \
BASEFEE=10000000000 \
MIN_SELF_DELEGATION_BASE=1000000000000000000000 \
HOMEDIR=/tmp/sanect-mainnet-genesis \
VAL_MNEMONIC="<the launch-day validator's mnemonic>" \
bash scripts/localnet.sh

After this builds, you have a genesis.json at /tmp/sanect-mainnet-genesis/config/genesis.json ready to ship with the Docker image.

What the script does NOT do for mainnet (manual steps) ​

  1. Doesn't run GenesisSplit.s.sol — do that on-chain at block N after launch.
  2. Doesn't include extra validators' gentx — those go through sanectd genesis add-genesis-account + gentx for each separately, OR via the new validator script.
  3. Doesn't bake any pre-deployed contracts. Privacy / DEX / Domain / Bridge contracts deploy via Foundry scripts post-genesis.

Part 2 — Per-service env-var diff (testnet → mainnet) ​

Each Railway service needs its env updated. Below is the COMPLETE delta per service.

Part 3 — Order of operations on Day 0 ​

  1. Run mainnet genesis builder locally — produces genesis.json
  2. Deploy primary mainnet validator container with the new genesis baked in
  3. Stand up 3 more validators (use scripts/spin-up-mainnet-validator.sh once it's written) pointing at primary as seed
  4. Wait for all 4 to reach height = 1 (primary self-stakes at gentx)
  5. Deploy protocol contracts in this order:
    • ShieldedPool (with 0x7cB61D… as initial owner)
    • HonkVerifier
    • DEX (Factory, Router, WSNCT, init code hash)
    • .snct registry + resolvers
    • Hyperlane core deploy (Mailbox + default ISM)
    • SanectHypAdapter + StubIgp + TrustedRelayerIsm
  6. Deploy 3 Gnosis Safes on the live mainnet
  7. Run GenesisSplit Foundry script — transfers all contract ownerships to GOVERNANCE_SAFE + sends initial balances to TREASURY_SAFE / OPS_SAFE
  8. Rotate Hyperlane relayer key — generate fresh keypair, fund, redeploy relayer container
  9. Update all Railway env vars per the diffs above, redeploy each service
  10. Verify every app loads + connects + chain functions: swap, bridge, stake, register .snct name, shield, unshield
  11. Snapshot publisher redeploy with mainnet R2 + SNAPSHOT_PUBLISHER=true
  12. Public announcement (per docs/launch-announcements.md when that PR lands)
  13. Pre-commit Phase 1 airdrop snapshot block publicly (Tweet + Telegram)
