Le mainnet utilise l'identifiant de chaîne 324 et de l'ETH pour payer les frais de gaz. Sepolia utilise https://zksync-sepolia-testnet.core.chainstack.com/YOUR_ENDPOINT_ID et l'identifiant de la chaîne 300. Voir le ZKsync Era tooling guide.
Utilisation eth_getBalance pour les soldes en ETH, eth_call pour les lectures de contrats, eth_getLogs pour l'historique des événements, et eth_sendRawTransaction for signed transactions. Connect over WebSocket for supported new-block and log subscriptions. Use native zks_* methods for fees, transaction details, and L1 batches. ZKsync method availability describes chain-specific APIs.
