Gas Limits

Contract calls consume gas. Omni enforces a gas limit when executing an xcall. You can specify a gas limit when making an xcall.

xcall(
   destChainId,  // destination chain id
   to,           // contract address on the destination chain
   data,         // abi encoded calldata, ex abi.encodeWithSignature("foo()")
   gasLimit      // gas limit to enforce on destination execution
)

If you do not provide sufficient gas for an xcall, its execution will revert. It's important to set appropriate gas limits for each xcall. Determine gas limits with testing.
