+# Wormhole Generalised Incentives
+
+This is a Wormhole implementation of Generalised INcentives. It works by Hijacking the Wormhole contract. It relies on the Wormhole state while re-implementing the verification logic in a way that is cheaper.
+
+# Address encoding
+
+Wormhole uses 32 bytes to represent addresses.
+
+EVM -> EVM
+
+```solidity
+
+function _to_bytes32(address target) internal returns(bytes memory) {
+    return abi.encode(target);
+}
+
+```
