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.

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

If you do not specify a gas limit, Omni enforces a default gas limit, currently set to 200_000. You can read the default gas limit via the portal contract.

/// @notice Default xmsg execution gas limit, enforced on destination chain

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 proper unit testing.
