Tools
Functions exposed to the LLM to take actions
read_contract
Read contract state from a blockchain. important:
In case of a tuple, don't use type tuple, but specify the inner types (found in the source) in order. For nested structs, include the substructs types.
Example:
struct DataTypeA {
DataTypeB b;
//the liquidity index. Expressed in ray
uint128 liquidityIndex;
}
struct DataTypeB {
address token;
}
results in outputs for function with return type DataTypeA (tuple in abi): outputs: [{"type": "address"}, {"type": "uint128"}]
