Going live

What will change

Live keys and a live API address. Live keys start with ptn_live_ and work only with the mainnet API, whose address we will publish at launch. Your test keys stay on the testnets.
Access on request. Your organization’s owner requests live access in the console.
A new gas wallet. The live gas wallet is a different address. Fund it on each chain you use.
New contracts. Your batcher and delegates on mainnet are new contracts with new addresses: register your hot wallets again, check each delegate with verify-delegate, and sign new authorizations for mainnet.

Signing. Your HSM, KMS or MPC signs raw 32-byte digests, your code matches the test vector, and it refuses chain ID 0.
Delegate checks. verify-delegate runs before the first authorization for every hot wallet, for example in your onboarding script or CI.
Idempotency. Every sweep and revocation carries an external_id, and your retries reuse it. See Idempotency.
Webhooks. Your receiver verifies signatures on the raw body, drops duplicate event ids and does not rely on the order of events. See Webhooks.
Gas wallet. You know how fast you spend gas, keep a few days of it, and have a low balance alert set.
Amounts. Amounts are integers in the token’s smallest units. On mainnet, USDT and USDC have 6 decimals on Ethereum and 18 on BSC: the same 1 USDT is 1000000 on one chain and 1000000000000000000 on the other.
Native coin deposits. If your users send ETH or BNB from exchanges, read Deposits from exchanges before you delegate those addresses.
Your settings. Decide whether to keep one unit on deposit addresses: see First and repeat sweeps.
