No, this is not like regular EVM event subscriptions

What eth_subscribe should have been

Think event subscriptions are old news? On Ethereum or other EVM chains, they're just events, no state, and no on-chain reactions. Somnia's push subscriptions deliver state along side event data, something other EVMs cannot offer.

Chain Comparison

• Other Chains: eth_subscribe gives events only—you still pull state separately, risking inconsistency.

• Somnia: Pushes event + state atomically; invokes Solidity handlers directly.

Code Comparison

Ethereum (Pull):

web3.eth.subscribe('logs', { address: '0x...' }, (err, log) => {
  // Now pull state manually
  contract.methods.balanceOf(...).call();
});

Somnia (Push):

sdk.subscribe({ ethCalls: ['balanceOf'], onData: (data) => {
  // Event + state delivered with `data`
});
